Guide XBee/XBee-PRO S2C 802.15.4 RF Modules are embedded solutions providing wireless end-point connectivity to devices. These devices use the IEEE 802.15.4 networking protocol for fast point-tomultipoint or peer-to-peer networking. They are designed for high-throughput applications requiring low latency and predictable communication timing. There are two footprints for the XBee/XBee-PRO S2C 802.15.4 RF Module hardware: through-hole (TH) and surface-mount (SMT). TH devices include a 20-pin header and require the placement of two 1x10 sockets on the carrier board for mounting the device. SMT devices include 37 pads. They are placed directly on the carrier board, which means they do not require holes or sockets for mounting. The TH version may be useful for prototyping and production, but we recommend SMT for highvolume applications, as the component can be placed automatically by a pick-and-place machine and you save the cost of a socket on each board. The XBee/XBee-PRO S2C 802.15.4 RF Module supports the needs of low-cost, low-power wireless sensor networks. The devices require minimal power and provide reliable delivery of data between devices. The devices operate within the ISM 2.4 GHz frequency band. The XBee/XBee-PRO S2C 802.15.4 RF Module uses S2C hardware and the Silicon Labs EM357 chipset. As the name suggests, the 802.15.4 module is over-the-air compatible with our Legacy 802.15.4 module (S1 hardware), and the TH versions of the new product are also form factor compatible with designs that use the Legacy module.

The effect is: XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 56 Operation n Networking The receiver may display duplicate packets. The solution is: n Set bit 0 of the C8 (802.15.4 Compatibility) parameter to 1 to enable TX compatibility mode in the XBee/XBee-PRO S2C 802.15.4 RF Module. This eliminates the transmission queue to avoid sending to multiple addresses simultaneously. It also limits the packet size to the levels of the Legacy 802.15.4 module. Networking The following table describes some common terms we use when discussing networks. Term Definition Association Establishing membership between end devices and a coordinator. Coordinator A full-function device (FFD) that provides network synchronization by polling nodes. End device When in the same network as a coordinator. Devices that rely on a coordinator for synchronization and can be put into states of sleep for low-power applications. PAN Personal Area Network. A data communication network that includes one or more end devices and optionally a coordinator. MAC Mode configuration Medium Access Control (MAC) Mode configures two functions: 1. Enables or disables the use of a Digi header in the 802.15.4 RF packet. When the Digi header is enabled (MM = 0 or 3), duplicate packet detection is enabled as well as certain AT commands. Modes 1 and 2 do not include a Digi header, which disables many features of the device. All data is strictly pass through. 2. Enables or disables MAC acknowledgment request for unicast packets. When MAC ACK is enabled (MM = 0 or 2), transmitting devices send packets with an ACK request so receiving devices send an ACK back (acknowledgment of RF packet reception) to the transmitter. If the transmitting device does not receive the ACK, it re-sends the packet up to three times or until the ACK is received. Modes 1 and 3 disable MAC acknowledgment. Transmitting devices send packets without an ACK request so receiving devices do not send an ACK back to the transmitter.  Broadcast messages are always sent with the MAC ACK request disabled. The following table summarizes the functionality. Mode Digi Header MAC ACK 0 (default) V V 1 2 3 V V XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 57 Operation Networking The default value for the MM configuration parameter is 0 which enables both the Digi header and the MAC acknowledgment. XBee retries configuration Configures the maximum number of retries the device executes in addition to the three retries provided by the 802.15.4 MAC. RR (XBee Retries) controls XBee retries configuration. It is also known as Application Retries. For each XBee retry, the 802.15.4 MAC can execute up to three retries. This only applies if MAC Mode configuration has Digi Header enabled. Transmit status based on MAC mode and XBee retries configurations When working in API mode, a transmit request frame sent by the user is always answered with a transmit status frame sent by the device, if the frame ID is non-zero. The following tables report the expected transmit status for unicast transmissions and the maximum number of MAC and application retries the device attempts.  The tables also report the transmit status reported when the device detects energy above the CCA threshold (when a CCA failure happens). The following table applies in either of these cases: l Digi Header is disabled. l Digi Header is enabled and XBee Retries (RR parameter) is equal to 0 (default configuration). Destination reachable Mac ACK Config Destination unreachable Retries CCA failure happened Retries TX status MAC App TX status MAC App Enabled 00 (Success) up to 3 0 01 (No acknowledgment received) 3 0 Disabled 00 (Success) 0 0 00 (Success) 0 0 Retries TX status MAC App 02 (CCA failure) 3 0 02 (CCA failure) 3 0 The following table applies when: l Digi Header is enabled and XBee Retries (RR parameter) is bigger than 0. Destination reachable Mac ACK Config Enabled Destination unreachable Retries Retries CCA failure happened TX status MAC App TX status MAC App TX status 00 (Success) up to 3 per app up to RR value 21 (Network ACK 3 RR value 02 (CCA failure) XBee/XBee-PRO S2C 802.15.4 RF Module User Guide Retries MAC App 3 RR value 58 Operation Networking Destination reachable Mac ACK Config Destination unreachable Retries TX status MAC Retries App TX status retry Disabled 00 (Success) 0 CCA failure happened MAC App TX status 0 RR value 02 (CCA failure) Retries MAC App 3 RR value Failure) up to RR value 21 (Network ACK Failure) Peer-to-peer networks By default, XBee/XBee-PRO S2C 802.15.4 RF Module modules are configured to operate within a peerto-peer network topology and therefore are not dependent upon master/slave relationships. This means that devices remain synchronized without the use of master/server configurations and each device in the network shares both roles of master and slave. Our peer-to-peer architecture features fast synchronization times and fast cold start times. This default configuration accommodates a wide range of RF data applications. Master/slave networks In a Master Slave network, there is a coordinator and one or more end devices. When end devices associate to the coordinator, they become members of that Personal Area Network (PAN). As such, they share the same channel and PAN ID. PAN IDs must be unique to prevent miscommunication between PANs. Depending on the A1 and A2 parameters, association may assist in automatically assigning the PAN ID and the channel. These parameters are specified below based on the network role (end device or coordinator). End device association End device association occurs if CE is 0 and A1 has bit 2 set. See the following table. Bit Hex value Meaning 0 0x01 Allow PAN ID reassignment 1 0x02 Allow channel reassignment 2 0x04 Auto association 3 0x08 Poll coordinator on pin wake By default, A1 is 0, which disables association and effectively causes an end device to operate in peerto-peer mode. When bit 2 is set, the end device associates to a coordinator. This is done by sending XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 59 Operation Networking out an active scan to detect beacons from nearby networks. The active scan selects one channel and transmits a Beacon Request command to the broadcast address and the broadcast PAN ID. It then listens on that channel for beacons from any coordinator operating on that channel. The listen time on each channel is determined by the SD parameter. Once that time expires, the active scan selects the next channel, repeating until all channels have been scanned. If A1 is 0x04 (bit 0 clear, bit 1 clear, and bit 2 set), then the active scan will reject all beacons that do not match both the configured PAN ID and the configured channel. This is the best way to join a particular coordinator. If A1 is 0x05 (bit 0 set, bit 1 clear, and bit 2 set), then the active scan will accept a beacon from any PAN ID, providing the channel matches. This is useful if the channel is known, but not the PAN ID. If A1 is 0x06 (bit 0 clear, bit 1 set, and bit 2 set), then the active scan will accept a beacon from any channel, providing the PAN ID matches. This is useful if the PAN ID is known, but not the channel. If A1 is 0x07 (bit 0 set, bit 1 set, and bit 2 set), then the active scan will accept a beacon from any PAN ID and from any channel. This is useful when the network does not matter, but the one with the best signal is desired. Whenever multiple beacons are received that meet the criteria of the active scan, then the beacon with the best link quality is selected. This applies whether A1 is 0x04, 0x05, 0x06, or 0x07. Before the End Device joins a network, the Associate LED will be on solid. After it joins a network, the Associate LED will blink twice per second. In the event that association parameters are changed after the end device is associated, the end device will leave the network and re-join in accordance with the new configuration parameters. Coordinator association Coordinator association occurs if CE is 1 and A2 has bit 2 set. See the following table. Bit Hex value Meaning 0 0x01 Allow PAN ID reassignment 1 0x02 Allow channel reassignment 2 0x04 Allow association By default, A2 is 0, which prevents devices from associating to the coordinator. So, if CE is 1 and A2 bit 2 is 0, the device still creates a network, but end devices are unable to associate to it. If A2 bit 2 is set, then joining is allowed after the coordinator forms a network. If A2 bit 0 is set, the coordinator issues an active scan. This means it will send out beacon requests to the broadcast address (0xFFFF) and the broadcast PAN ID (0xFFFF). Then, it will listen for beacons. The listen time is determined by the SD parameter. Then the same beacon request is sent out on the next channel and the device listens for beacon responses on that channel. This process repeats until each channel in the channel mask (SC) is scanned for SD time. If none of the beacons on any of the channels return a PAN ID equivalent with the ID parameter, then the coordinator will use the ID parameter for the PAN ID of the new network it forms. But, if a beacon response matches the PAN ID of the coordinator, the coordinator will form a PAN on a unique PAN ID. If A2 bit 0 is clear, then the coordinator will form a network on the PAN ID identified by the ID parameter, without regard to another network that might have the same PAN ID. If A2 bit 1 is set, the coordinator will issue an energy scan, similar to the active scan. It will listen on each channel specified in the SC parameter for the time indicated by the SD parameter. After the scan is complete, the channel with the least energy is selected to form the new network. XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 60 Operation Networking If A2 bit 1 is clear, then no energy scan is performed and the CH parameter is used to select the channel of the new network. If bits 0 and 1 of A2 are both set, then an active scan is done followed by an energy scan. However, the channels on which the active scan finds a coordinator are eliminated as possible channels for the energy scan, unless such an action would eliminate all channels. If beacons are found on all channels in the channel mask, then then the energy scan behaves the same as it would if beacons are not found on any of those channels. Therefore, the active scan will be performed on all channels in the channel mask. Then, an energy scan will be performed on the channels in the channel mask that did not find a coordinator. Depending on the result of the active scan, the set of channels for the energy scan varies. If a PAN ID is found on all the channels in the channel mask, then the energy scan operates on all the channels in the channel mask. If at least one of the channels in the channel mask did not find a PAN ID, then the channels with PAN IDs are eliminated from consideration for the energy scan. After the energy scan completes, the channel with the least energy is selected for forming the new network. Whenever CE, ID, A2, or MY changes, the network will leave and association will recur with the new parameters. Any end devices associated to the coordinator prior to changing one of these parameters will lose association. For this reason, it is important not to change these parameters on a coordinator unless needed. Before the Coordinator forms a network, the Associate LED will be on solid. After it forms a network, the Associate LED will blink once per second. Indirect addressing The XBee/XBee-PRO S2C 802.15.4 RF Module may hold indirect messages until it runs out of buffers and the size of those messages does not matter. A brief summary follows: A coordinator (CE = 1) must have SP set to a non-zero value to use indirect addressing. Otherwise, all frames will be sent directly, assuming the target device is awake. For best operation, SP and ST should be set to match the SP and ST values of the end nodes. The coordinator will hold onto an indirect message until it receives a poll from the device to which the message is addressed, or until a timeout, whichever occurs first. The timeout is 2.5 times the value of SP. After an indirect message is sent, subsequent messages to the same address will be sent directly for a period of time equal to the ST parameter. The assumption is that the end device will remain awake for ST time after the last transmission or reception. Therefore, after a poll, every transmission and reception involving that address restart the ST timer. After the ST timer expires, the coordinator will again use indirect messaging (i.e it will hold messages awaiting a poll.) End devices using cyclic sleep send a poll to the coordinator when they wake up unless SO bit 0 is set. End devices using pin sleep may be configured to send a poll on a pin wakeup by setting bit 3 of A1. Also the FP command can be used to send a poll upon exiting command mode. However, the poll is not sent while in command mode. Rather the poll is sent after changes are applied so that the module is ready to receive data after the poll is sent. It is more difficult to use indirect addressing with pin sleep than with cyclic sleep because the end device must wake up periodically to poll for the data from the coordinator. Otherwise, the coordinator will discard the data. Therefore, cyclic sleep is the only recommended sleep mode for indirect addressing. Association indicators There are two types of association indicators: Asynchronous device status messages, and on demand queries. Asynchronous device status messages occur whenever a change occurs and API mode is enabled. On demand queries occur when the AI command is issued, which can occur in Command mode, in API mode, or as a remote command. XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 61 Operation Networking Device Status Messages Not all device status messages are related with association, but for completeness all device status types reported by XBee/XBee-PRO S2C 802.15.4 RF Module are listed in the following table. Type Meaning 0x00 Hardware reset. 0x01 Watchdog reset. 0x02 End device successfully associated with a coordinator. 0x03 End device disassociated from coordinator or coordinator failed to form a new network. 0x06 Coordinator formed a new network. 0x0D Input voltage on the XBee-PRO device is too high, which prevents transmissions. Association indicator status codes The XBee/XBee-PRO S2C 802.15.4 RF Module code can potentially give any of the status codes in the following table. Code Meaning 0x00 Coordinator successfully started, End device successfully associated, or operating in peer to peer mode where no association is needed. 0x03 Active Scan found a PAN coordinator, but it is not currently accepting associations. 0x04 Active Scan found a PAN coordinator in a beacon-enabled network, which is not a supported feature. 0x05 Active Scan found a PAN, but the PAN ID does not match the configured PAN ID on the requesting end device and bit 0 of A1 is not set to allow reassignment of PAN ID. 0x06 Active Scan found a PAN on a channel does not match the configured channel on the requesting end device and bit 1 of A1 is not set to allow reassignment of the channel. 0x0C Association request failed to get a response. 0x13 End device is disassociated or is in the process of disassociating. 0xFF Initialization time; no association status has been determined yet. Sleep Sleep is implemented to support installations where a mains power source is not available and a battery is required. In order to increase battery life, the device sleeps, which means it stops operating. It can be woken by a timer expiration or a pin. For more information about sleep modes, see Sleep modes. Sleep conditions Since instructions stop executing while the device is sleeping, it is important to avoid sleeping when the device has work to do. For example, the device will not sleep if any of the following are true: XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 62 Operation Clear Channel Assessment (CCA) 1. The device is operating in command mode, or in the process of getting into command mode with the +++ sequence. 2. The device is processing AT commands from API mode 3. The device is processing remote AT commands 4. Something is queued to the serial port and that data is not blocked by RTS flow control If each of the above conditions are false, then sleep may still be blocked in these cases: 1. Enough time has not expired since the device has awakened. a. If the device is operating in pin sleep, the amount of time needed for one character to be received on the UART is enough time. b. If the device is operating in cyclic sleep, enough time is defined by a timer. The duration of that timer is: i. defined by ST if in SM 5 mode and it is awakened by a pin ii. 30 ms to allow enough time for a poll and a poll response iii. 750 ms to allow enough time for association, in case that needs to happen c. In addition, the wake time is extended by an additional ST time when new OTA data or serial data is received. 2. Sleep Request pin is not asserted when operating in pin sleep mode 3. Data is waiting to be sent OTA. Clear Channel Assessment (CCA) Prior to transmitting a packet, the device performs a CCA (Clear Channel Assessment) on the channel to determine if the channel is available for transmission. The detected energy on the channel is compared with the CA (Clear Channel Assessment) parameter value. If the detected energy exceeds the CA parameter value, the device does not transmit the packet. Also, the device inserts a delay before a transmission takes place. You can set this delay using the RN (Backoff Exponent) parameter. If you set RN to 0, then there is no delay before the first CCA is performed. The RN parameter value is the equivalent of the “minBE” parameter in the 802.15.4 specification. The transmit sequence follows the 802.15.4 specification. By default, the MM (MAC Mode) parameter = 0. On a CCA failure, the device attempts to re-send the packet up to two additional times. When in Unicast packets with RR (Retries) = 0, the device executes two CCA retries. Broadcast packets always get two CCA retries. Note Customers in Europe who have the XBee 802.15.4 module must manage their CCA settings. See CA (CCA Threshold) for CA values. CCA operations CCA is a method of collision avoidance that is implemented by detecting the energy level on the transmission channel before starting the transmission. The CCA threshold (defined by the CA parameter) defines the energy level that it takes to block a transmission attempt. For example, if CCA is set to the default value of 0x2C (which is interpreted as -44 dBm) then energy detected above the 44 dBm level (for example -40 dBm) temporarily blocks a transmission attempt. But if the energy level is less than that (for example -50 dBm), the transmission is not blocked. The intent of this feature is to prevent simultaneous transmissions on the same channel. XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 63 Operation Serial interface CCA can be set down to 0x50 (or -80 dBm), which approaches the sensitivity level. Setting such a threshold may not work in a noisy environment. In the event that the energy level exceeds the threshold, the transmission is blocked some random number of backoff periods. The number of backoff periods is defined by random(2^n - 1) where the initial value of n is defined by the RN parameter and it increments after each failure. When RN is set to its default value of 0, then 2^n -1 is 0, preventing any delay before the first energy detection on a new frame. However, n increments after each CCA failure, giving a greater range for the number of backoff periods between each energy detection cycle. In the event that five energy detection cycles occur and each one detects too much energy, the application tries again 1 to 48 ms later. After the application retries are exhausted, then the transmission fails with a CCA error. Whenever the MAC code reports a CCA failure, meaning that it performed five energy detection cycles with exponential random back-offs, and each one failed, the EC parameter is incremented. The EC parameter can be read at any time to find out how noisy the operating channel is. It continues to increment until it reaches its maximum value of 0xFFFF. To get new statistics, you can always set EC back to 0. Serial interface The XBee/XBee-PRO S2C 802.15.4 RF Module interfaces to a host device through a serial port. The device can communicate through its serial port with: n Through logic and voltage compatible universal asynchronous receiver/transmitter (UART). n Through a level translator to any serial device, for example, through an RS-232 or USB interface board. n Through a SPI, as described in SPI signals. Select a serial port The device has two serial ports and only one is active at a time. To be active, a port must be enabled and in use. The UART is always enabled. The SPI is enabled if it is configured. To be configured, SPI_MISO, SPI_ MOSI, SPI_SSEL , and SPI_CLK must all be configured as peripherals. On the surface-mount device, these lines are configured as peripherals by setting P5, P6, P7, and P8 to 1. This is also the default configuration for surface-mount devices. On the through-hole device, those pins are not available and SPI is disabled by default. Therefore, to configure the SPI pins on a through-hole device, hold DOUT low during a reset. If the UART is not hooked up, then DOUT can be treated as an input to force the device into SPI mode. It is best to follow this special operation by a WR operation so that the SPI port will still be enabled on future resets without forcing DOUT low. Once the SPI port is enabled by either means, it is still not active until the external SPI master asserts SPI_SSEL low. After the SPI port is active, the device continues to use the SPI port until the next reset. Serial receive buffer When serial data enters the device through the DIN pin (or the MOSI pin), it stores the data in the serial receive buffer until the device can process it. Under certain conditions, the device may not be able to process data in the serial receive buffer immediately. If large amounts of serial data are sent to the device such that the serial receive buffer would overflow, then it discards new data. If the UART is in use, you can avoid this by the host side honoring CTS flow control. XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 64 Operation Serial interface Serial transmit buffer When the device receives RF data, it moves the data into the serial transmit buffer and sends it out the UART or SPI port. If the serial transmit buffer becomes full and the system buffers are also full, then it drops the entire RF data packet. Whenever the device receives data faster than it can process and transmit the data out the serial port, there is a potential of dropping data. UART data flow Devices that have a UART interface connect directly to the pins of the XBee/XBee-PRO S2C 802.15.4 RF Module as shown in the following figure. The figure shows system data flow in a UART-interfaced environment. Low-asserted signals have a horizontal line over the signal name. Serial data A device sends data to the XBee/XBee-PRO S2C 802.15.4 RF Module's UART through TH pin 3/SMT pin 4 DIN as an asynchronous serial signal. When the device is not transmitting data, the signals should idle high. For serial communication to occur, you must configure the UART of both devices (the microcontroller and the XBee/XBee-PRO S2C 802.15.4 RF Module) with compatible settings for the baud rate, parity, start bits, stop bits, and data bits. Each data byte consists of a start bit (low), 8 data bits (least significant bit first) and a stop bit (high). The following diagram illustrates the serial bit pattern of data passing through the device. The diagram shows UART data packet 0x1F (decimal number 31) as transmitted through the device. Flow control The XBee/XBee-PRO S2C 802.15.4 RF Module maintains buffers to collect serial and RF data that it receives. The serial receive buffer collects incoming serial characters and holds them until the device can process them. The serial transmit buffer collects the data it receives via the RF link until it XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 65 Operation Serial interface transmits that data out the serial port. The following figure shows the process of device buffers collecting received serial data. CTS flow control If you enable CTS flow control (by setting D7 to 1), when the serial receive buffer is 17 bytes away from being full, the device de-asserts CTS (sets it high) to signal to the host device to stop sending serial data. The device reasserts CTS after the serial receive buffer has 34 bytes of space. The maximum space available for receiving serial data is 174 bytes, which is enough to hold 1.5 full packets of data. Flow control threshold Use the FT parameter to set the flow control threshold. Since the receive serial buffer is 174 bytes, you cannot set FT to more than 174-12 = 162 bytes. This allows up to 17 bytes of data to come in after CTS is de-asserted before data is dropped. The default value of FT is 109, leaving space for an external device that responds slowly to CTS being de-asserted. The minimum value of FT is 17, which is the minimal operational level. RTS flow control If you send the D6 command to enable RTS flow control, the device does not send data in the serial transmit buffer out the DOUT pin as long as RTS is de-asserted (set high). Do not de-assert RTS for long periods of time or the serial transmit buffer will fill. If the device receives an RF data packet and the serial transmit buffer does not have enough space for all of the data bytes, it discards the entire RF data packet. If the device sends data out the UART when RTS is de-asserted (set high) the device could send up to five characters out the UART port after RTS is de-asserted. Cases in which the DO buffer may become full, resulting in dropped RF packets: 1. If the RF data rate is set higher than the interface data rate of the device, the device may receive data faster than it can send the data to the host. Even occasional transmissions from a large number of devices can quickly accumulate and overflow the transmit buffer. 2. If the host does not allow the device to transmit data out from the serial transmit buffer due to being held off by hardware flow control. Asynchronous Parameters Asynchronous communication over a UART is configured with a start bit, data bits, parity, stop bits, and baud rate. Out of these, only parity and baud rate are configurable on the device for 802.15.4. This XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 66 Operation SPI operation means that the connecting micro-controller must match the the start bits (1), the data bits (8), and the stop bits (1) of the device for proper communication. Parity Use the NB command to configure parity; see NB (Parity). SPI operation This section specifies how SPI is implemented on the device, what the SPI signals are, and how full duplex operations work. SPI signals The XBee/XBee-PRO S2C 802.15.4 RF Module supports SPI communications in slave mode. Slave mode receives the clock signal and data from the master and returns data to the master. The SPI port uses the following signals on the device: Signal SMT pin SMT applicable AT # command TH Pin TH applicable AT # command SPI_MOSI (Master out, Slave in) 16 P6 11 D4 SPI_MISO (Master in, Slave out) 17 P5 4 P2 SPI_SCLK (Serial clock) 14 P8 18 D2 SPI_SSEL (Slave select) 15 P7 17 D3 SPI_ATTN (Attention) 12 P9 19 D1 By default, the inputs have pull-up resistors enabled. Use the PR command to disable the pull-up resistors. When the SPI pins are not connected but the pins are configured for SPI operation, then the device requires the pull-ups for proper UART operation. Signal description SPI_MISO: When SPI_CLK is active, the device outputs the data on SPI_MISO at the SPI_CLK rate. If there are other SPI slave devices connected to the same SPI master, then the SPI_MISO output from XBee device must be externally tri-stated when SPI_SSEL is de-asserted to prevent multiple devices from driving SPI_MISO. SPI_MOSI: The SPI master outputs data on this line at the SPI_CLK rate after it selects the desired slave. When you configure the device for SPI operations, this pin is an input. SPI_SCLK: The SPI master outputs a clock on this pin, and the rate must not exceed the maximum allowed, 5 Mb/s. This signal clocks data transfers on MOSI and MISO. SPI_SSEL: The SPI master outputs a low signal on this pin to select the device as an SPI slave. When you configure the device for SPI operations, this pin is an input. This signal enables serial communication with the slave. SPI_ATTN: The device asserts this pin low when it has data to send to the SPI master. When you configure this pin for SPI operations, it is an output (not tri-stated). This signal alerts the master that the slave has data queued to send. The device asserts this pin as soon as data is available to send to the SPI master and it remains asserted until the SPI master has clocked out all available data. XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 67 Operation SPI operation SPI parameters Most host processors with SPI hardware allow you to set the bit order, clock phase and polarity. For communication with all XBee/XBee-PRO S2C 802.15.4 RF Modules, the host processor must set these options as follows: n Bit order: send MSB first n Clock phase (CPHA): sample data on first (leading) edge n Clock polarity (CPOL): first (leading) edge rises All XBee/XBee-PRO S2C 802.15.4 RF Modules use SPI mode 0 and MSB first. Mode 0 means that data is sampled on the leading edge and that the leading edge rises. MSB first means that bit 7 is the first bit of a byte sent over the interface. SPI and API mode The SPI only operates in API mode 1. The SPI does not support Transparent mode or API mode 2 (with escaped characters). This means that the AP configuration only applies to the UART interface and is ignored while using the SPI. Full duplex operation When using SPI on the XBee/XBee-PRO S2C 802.15.4 RF Module the device uses API operation without escaped characters to packetize data. The device ignores the configuration of AP because SPI does not operate in any other mode. SPI is a full duplex protocol, even when data is only available in one direction. This means that whenever a device receives data, it also transmits, and that data is normally invalid. Likewise, whenever a device transmits data, invalid data is probably received. To determine whether or not received data is invalid, the firmware places the data in API packets. SPI allows for valid data from the slave to begin before, at the same time, or after valid data begins from the master. When the master sends data to the slave and the slave has valid data to send in the middle of receiving data from the master, a full duplex operation occurs, where data is valid in both directions for a period of time. Not only must the master and the slave both be able to keep up with the full duplex operation, but both sides must honor the protocol. The following figure illustrates the SPI interface while valid data is being sent in both directions. Slave mode characteristics In slave mode, the following apply: XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 68 Operation I/O support n SPI Clock rates up to 5 MHz (5 Mb/s) are possible. n Data is MSB first. n It uses Frame Format Mode 0. This means CPOL= 0 (idle clock is low) and CPHA = 0 (data is sampled on the clock’s leading edge). The picture below diagrams Mode 0. n The SPI port is setup for API mode and is equivalent to AP = 1. The following picture shows the frame format for SPI communications. I/O support The following topics describe analog and digital I/O line support, line passing and output control. XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 69 Operation I/O support Digital I/O line support Digital I/O is available on pins D0 through D8. Each of these pins may be configured as 3, 4, or 5 with the following meanings: n 3 is digital input n 4 is digital output low n 5 is digital output high Pins D0 through D8 are available for digital input, but only D0 through D7 are available for digital output. Function SMT pin TH pin AT command DIO0 33 20 D0 (DIO0/AD0) DIO1 32 19 D1 (DIO1/AD1) DIO2 31 18 D2 (DIO2/AD2) DIO3 30 17 D3 (DIO3/AD3) DIO4 24 11 D4 (DIO4) DIO5 28 15 D5 (DIO5/ASSOCIATED_INDICATOR) DIO6 29 16 D6 (DIO6/RTS) DIO7 25 12 D7 (DIO7/CTS) DIO8 10 9 D8 (DIO8/SLEEP_REQUEST) Analog input Analog input is available on D0 through D3 by configuring these parameters to 2. Analog input is not available on D4 and D5. On demand I/O sampling You can use the IS (Force Sample) command to sample pins configured as digital I/O and analog input. If no pins are configured in this manner (with the DO - D8 commands set to 2, 3, 4, or 5), then the IS command returns an error. In Command mode, the output is: Output Description 01 Indicates one sample. That is the only possibility for Command mode. 20E Mask to indicate which lines are sampled (A0, D3, D2, and D1). 00A Digital sample indicates D3 high, D2 low, and D1 high. 3FF Analog sample for A0 indicates that A0 is reading maximum voltage of 1.2 V. In API mode, the output is: 7E 00 0C 83 00 00 00 00 01 03 3E 01 2A 02 10 FD XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 70 Operation I/O support In this example, note the following: 83 indicates RX Packet: 16-bit Address I/O frame (0x83). 00 00 indicates 16-bit source address. 00 indicates RSSI (does not apply). 00 indicates options. 01 indicates the number of samples. 03 3E mask to indicate which lines are sampled (A0, D8, D5, D4, D3, D2, and D1). 01 2A digital sample that indicates that D8 is high, D5 is high, D4 is low, D3 is high, D2 is low, and D1 is high. 02 10 indicates that A0 has input voltage nearly half of capacity, where 03 FF would indicate the full voltage of 1.2 V = 1200 mV.

I/O data format I/O data begins with a header. The first byte of the header defines the number of samples forthcoming. The last two bytes of the header (Channel Indicator) define which inputs are active. Each bit represents either a DIO line or ADC channel. The following figure illustrates the bits in the header. Sample data follows the header and the channel indicator frame determines how to read the sample data. If any of the DIO lines are enabled, the first two bytes are the DIO sample. The ADC data follows. ADC channel data is represented as an unsigned 10-bit value right-justified on a 16- bit boundary. The following figure illustrates the sample data bits. XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 71 Operation I/O support Multiple samples per packet The IT parameter specifies how many I/O samples can be transmitted in a single OTA packet. Any single-byte value (0 - 0xFF) is accepted for input. However, the value is adjusted downward based on how many I/O samples can fit into a maximum size packet; see Maximum payload. A query of the IT parameter after changes are applied tells how many I/O samples actually occur. Since MM must be 0 or 3 to send I/O samples, the maximum payload in the best of conditions (short source address, short destination address, and no encryption) is 114 bytes. Seven of those bytes are used by the command header and the I/O header, leaving 107 bytes for I/O samples. The minimum I/O sample is 2 bytes. Therefore the maximum possible usable value for IT is 53 (or 0x35). API support I/O data is sent out the UART using an API frame. All other data can be sent and received using Transparent Operation or API frames if API mode is enabled (AP > 0). API Operations support two RX (Receive) frame identifiers for I/O data (set 16-bit address to 0xFFFE and the device does 64-bit addressing): n 0x82 for RX Packet: 64-bit Address I/O n 0x83 for RX Packet: 16-bit Address I/O The API command header is the same as shown in 64-bit Receive Packet - 0x80 and 16-bit I/O Sample Indicator - 0x83. RX data follows the format described in I/O data format. Periodic I/O sampling Periodic I/O sampling is done by periodically gathering samples on the source node and sending the samples to the destination node to output on its serial port. Source node On the source node, the IR parameter specifies how many milliseconds between samples. The IT parameter specifies how many samples will be sent OTA in a single packet, and the DH/DL parameters designate the node that will receive the samples. In addition MM must be 0 or 3 for I/O samples to be sent. The maximum value of IR is 0xFFFF. If IR is 0, periodic I/O sampling is disabled. Otherwise, IR specifies the number of milliseconds between samples. If IT is 0, than an I/O sample is sent every IR milliseconds. If IR is greater than 0, then an I/O sample is sent every IR*IT milliseconds. Any single-byte value (0 - 0xFF) is accepted for input. However, the value is adjusted downward based on how many I/O samples can fit into a maximum size packet. A query of the IT parameter after changes are applied tells how many I/O samples will actually occur. Since MM must be 0 or 3 to send I/O samples, the maximum payload in the best of conditions (short source address, short destination address, and no encryption) is 114 bytes. Seven of those bytes are used by the command header and the I/O header, leaving 107 bytes for I/O samples. The minimum I/O sample is 2 bytes. Therefore the maximum possible usable value for IT is 53 (or 0x35). XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 72 Operation I/O support Although samples may be taken every millisecond, IR*IT should be at least 20 milliseconds. This allows time for OTA transmission and output on the serial port of the receiving module. Destination node On the destination node, the IU parameter enables the serial port to output I/O samples it receives. IU is set to 1 by default. If IU is set and the destination node is not in Command mode, it displays samples it receives on its serial port in API format. The AP parameter is ignored in this case. Data format The I/O sample is formatted as follows: IT Mask Samples 1 byte 2 bytes 2 * number of samples The IT field is described above. The Mask is a bit field formatted as follows: Reserved A3 - A0 D8 - D0 3 bits 4 analog bits 9 digital bits If you set any of the digital bits, then a digital sample follows the Mask. For every analog bit that is set, there is a 10-bit sample using two bytes where A0 is included first and A3 is included last. The number of samples indicated by the mask is repeated IT times. The mask is not repeated. The sending node sends I/O samples to the address specified by DH/DL. The receiving node displays the samples as described above, providing API mode is enabled, the node is not in Command mode, and the IU parameter is 1 (IU is 1 by default). If any of these are false, the I/O sample is discarded without being displayed. Change Detect I/O sampling When you use the IC (DIO Change Detect) command to enable DIO Change Detect, DIO lines 0 - 7 are monitored. When a change is detected on a DIO line, the following occurs: 1. This packet does not contain DIO8 and does not contain any analog samples. However, it does contain a digital reading of the D0 - D7 pins configured for input or output, whether or not all those bits are set in IC. 2. Any queued samples are transmitted before the change detect data. This may result in receiving a packet with less than IT (Samples before TX) samples. Change detect does not affect Pin Sleep wake-up. The D8 pin (DI8/SLEEP_RQ/DTR ) is the only line that wakes a device from Pin Sleep. If not all samples are collected, the device still enters Sleep mode after a change detect packet is sent. Change detect is only supported when the Dx (DIOx Configuration) parameter equals 3, 4 or 5. XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 73 Operation I/O support Wakeup I/O sampling Bit 2 of the SO parameter specifies whether or not the device automatically samples the ADC/DIO lines on wakeup. On the receiving side the I/O sample may go to the I/O pins, the serial port, both, or neither based on the settings of the IA (I/O Input Address) and IU (I/O Output Enable) parameters. For more information, see SO (Sleep Options), IA (I/O Input Address), and IU (I/O Output Enable). Sample rate (interval) The Sample Rate (Interval) feature allows enabled ADC and DIO pins to be read periodically on devices that are not configured to operate in Sleep Mode. When one of the Sleep Modes is enabled and the IR (Sample Rate) parameter is set, the device stays awake until IT (Samples before TX) samples have been collected. Once a particular pin is enabled, the appropriate sample rate must be chosen. The maximum sample rate that can be achieved while using one A/D line is 1 sample/ms or 1 kHz. The device cannot keep up with transmission when IR and IT are equal to 1 and we do not recommend configuring the device to sample at rates greater than once every 20 ms. I/O line passing You can configure XBee/XBee-PRO S2C 802.15.4 RF Modules to perform analog and digital line passing. When a device receives an RF I/O sample data packet, you can set up the receiving device to update any enabled outputs (PWM and DIO) based on the data it receives. Digital I/O lines are mapped in pairs; pins configured as digital input on the transmitting device affect the corresponding digital output pin on the receiving device. For example: DI5 (pin 25) can only update DO5 (pin 25). No I/O line passing occurs if the receiving device does not have the corresponding pins set for output. For Analog Line Passing, the XBee/XBee-PRO S2C 802.15.4 RF Module has two PWM output pins that simulate the voltage measured by the ADC lines AD0 and AD1. For example, when configured as an ADC, AD0 (pin 33) updates PWM0 (pin 7); AD1 (pin 32) updates PWM1 (pin 8). The default setup is for outputs to not be updated. Instead, a device sends I/O sample data out the serial interface in API mode, even if the destination node is not configured for API mode. You can use the IU command to disable sample data output. To enable updating the outputs, set the IA (I/O Input Address) parameter with the address of the device that has the appropriate inputs enabled. This effectively binds the outputs to a particular device’s input. This does not affect the ability of the device to receive I/O line data from other devices - only its ability to update enabled outputs. Set the IA parameter to 0xFFFF (broadcast address) to set up the device to accept I/O data for output changes from any device on the network. For line passing to function, the device configured with inputs must generate sample data. When outputs are changed from their configured state, the device can be setup to return the output level to its configured state after a timer expires. The timers are set using the Tn (Dn Output Timer) and PT (PWM Output Timeout) commands. The timers are reset every time the device receives a valid I/O sample packet with a matching IA address. You can adjust the IT (Samples before TX) and IR (Sample Rate) parameters on the transmitting device to keep the outputs set to their active output if the system needs more time than the timers can handle. Alternatively, the timers can be set to 0xFF, which prevents them from expiring (in other words, the outputs remain in the state specified by the input device indefinitely). XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 74 Operation Sleep support I/O line passing details The same message is received for both I/O sampling and for I/O line passing. But I/O line passing only occurs if IA matches the short or long address of the sending node or if IA is 0xFFFF to match a sample from any node. The default value of IA is 0xFFFFFFFF, which prevents I/O line passing from occurring on the node because no node has that address. Additionally, the receiving device must have a matching value for output. For example, if an ADC0 sample is received, then P0 must be configured with 2 for PWM output. Otherwise, the analog signal will not be reflected with a matching PWM signal. Likewise, if the sample indicates that D2 is high, but D2 is not set to 4 or 5 on the receiving device, then the D2 pin will not be affected by I/O line passing. When a digital output pin is set to something different than its configured value, that pin may return to its configured value after the time specified for the corresponding timer. T0 specifies how long D0 will hold its non-configured value and T1 specifies how long D1 will hold its non-configured value. A value of 0xFF indicates that a pin holds the value of the input of the corresponding device indefinitely and a value less than 0xFF specifies how many tenth second units the pin holds the non-configured value. For PWM outputs, PT timer applies to both PWM0 and PWM1. A value of 0xFF allows the PWM pin to output a duty cycle reflective of the analog input indefinitely and a smaller value indicates how many 10th second units before PWM output reverts to the duty cycle specified by M0 or M1. Output control The IO (Digital Output Level) command controls the output levels of D0 through D7 that are configured as output pins (either 4 or 5). These values override the configured output levels of the pins until they are changed again (the pins do not automatically revert to their configured values after a timeout.) You can use the IO command to trigger a sample on change detect. Sleep support Set SO (Sleep Options) bit 1 to suppress automatic wake-up sampling. When a device wakes, it always performs a sample based on any active ADC or DIO lines. This allows sampling based on the sleep cycle whether it be Cyclic Sleep (SM = 4 or 5) or Pin Sleep (SM = 1). Set the IR (Sample Rate) parameter to gather more samples when awake. For Cyclic Sleep modes: If the IR parameter is set, the device stays awake until the IT (Samples before TX) parameter is met. The device stays awake for ST (Time before Sleep). Sleep modes Sleep modes enable the device to enter states of low-power consumption when not in use. In order to enter Sleep mode, one of the following conditions must be met (in addition to the device having a non-zero SM parameter value): n SLEEP_RQ/DTR (TH pin 9/SMT pin 10) is asserted and the device is in a pin sleep mode (SM = 1, or 5) n The device is idle (no data transmission or reception) for the amount of time defined by the ST (Time before Sleep) parameter. Note ST is only active when SM = 4 or 5. The following table shows the sleep mode configurations. XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 75 Operation Sleep support Sleep mode Description SM 0 No sleep SM 1 Pin sleep SM 4 Cyclic sleep SM 5 Cyclic sleep with pin wake-up Pin Sleep mode (SM = 1) Pin Sleep mode minimizes quiescent power (power consumed when in a state of rest or inactivity). This mode is voltage level-activated; when Sleep_RQ (TH pin 9/SMT pin 10) is asserted, the device finishes any transmit, receive or association activities, enters Idle mode, and then enters a state of sleep. The device does not respond to either serial or RF activity while in pin sleep. To wake a sleeping device operating in Pin Sleep mode, de-assert Sleep_RQ. The device wakes when Sleep_RQ is de-asserted and is ready to transmit or receive when the CTS line is low. When waking the device, the pin must be de-asserted at least two 'byte times' after CTS goes low. This assures that there is time for the data to enter the DI buffer. Cyclic Sleep mode (SM = 4) The Cyclic Sleep modes allow devices to periodically check for RF data. When the SM parameter is set to 4, the XBee/XBee-PRO S2C 802.15.4 RF Module is configured to sleep, then wakes once per cycle to check for data from a coordinator. The Cyclic Sleep Remote sends a poll request to the coordinator at a specific interval set by the SP (Cyclic Sleep Period) parameter. The coordinator transmits any queued data addressed to that specific remote upon receiving the poll request. ON_SLEEP goes high and CTS goes low each time the remote wakes, allowing for communication initiated by the remote host if desired. Cyclic Sleep with Pin Wake-up mode (SM = 5) Use this mode to wake a sleeping remote device through either the RF interface or by de-asserting SLEEP_RQ for event-driven communications. The cyclic sleep mode works as described previously with the addition of a pin-controlled wake-up at the remote device. The SLEEP_RQ pin is leveltriggered. The device wakes when a low is detected then set CTS low as soon as it is ready to transmit or receive. Any activity resets the ST (Time before Sleep) timer, so the device goes back to sleep only after there is no activity for the duration of the timer. Once the device wakes (pin-controlled), it ignores further pin activity. The device transitions back into sleep according to the ST time regardless of the state of the pin. Sleep parameters The following AT commands are associated with the sleep modes. See the linked commands for the parameter's description, range and default values. n SM (Sleep Mode) n SO (Sleep Options) n A1 (End Device Association) n ST (Time before Sleep) XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 76 Operation Sleep support n SP (Cyclic Sleep Period) n DP (Disassociated Cyclic Sleep Period) Sleep current The following table shows the sleep current during the XBee/XBee-PRO S2C 802.15.4 RF Module sleep modes.

United States (FCC) 172 Regulatory information United States (FCC) RF exposure If you are an integrating the XBee into another product, you must include the following Caution statement in OEM product manuals to alert users of FCC RF exposure compliance: CAUTION! To satisfy FCC RF exposure requirements for mobile transmitting devices, a separation distance of 20 cm or more should be maintained between the antenna of this device and persons during device operation. To ensure compliance, operations at closer than this distance are not recommended. The antenna used for this transmitter must not be colocated in conjunction with any other antenna or transmitter. FCC publication 996369 related information In publication 996369 section D03, the FCC requires information concerning a module to be presented by OEM manufacturers. This section assists in answering or fulfilling these requirements. 2.1 General No requirements are associated with this section. 2.2 List of applicable FCC rules This module conforms to FCC Part 15.247. 2.3 Summarize the specific operational use conditions Certain approved antennas require attenuation for operation. For the XBee/XBee-PRO S2C 802.15.4 RF Module, see FCC-approved antennas (2.4 GHz). Host product user guides should include the antenna table if end customers are permitted to select antennas. 2.4 Limited module procedures Not applicable. 2.5 Trace antenna designs While it is possible to build a trace antenna into the host PCB, this requires at least a Class II permissive change to the FCC grant which includes significant extra testing and cost. If an embedded trace antenna is desired, select the XBee module variant with the preferred antenna. 2.6 RF exposure considerations For RF exposure considerations see RF exposure and FCC-approved antennas (2.4 GHz). Host product manufacturers need to provide end-users a copy of the “RF Exposure” section of the manual: RF exposure. 2.7 Antennas A list of approved antennas is provided for the XBee/XBee-PRO S2C 802.15.4 RF Modules.

Each footprint requires different mounting techniques. We designed a footprint that allows you to attach either device to a PCB. The following drawing shows the layout. XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 190 Migrate from XBee through-hole to surface-mount devices Mount the devices The round holes in the diagram are for the TH design, and the semi-oval pads are for the SMT design. Pin 1 of the TH design is lined up with pad 1 of the SMT design, but the pins are actually offset by one pad; see Pin mapping. By using diagonal traces to connect the appropriate pins, the layout will work for both devices. PCB design and manufacturing contains information on attaching the SMT device.

The device will reflow during this cycle, and therefore must not be reflowed upside down. Take care not to jar the device while the solder is molten, as this can remove components under the shield from their required locations. Hand soldering is possible and should be performed in accordance with approved standards. The device has a Moisture Sensitivity Level (MSL) of 3. When using this product, consider the relative requirements in accordance with standard IPC/JEDEC J-STD-020. In addition, note the following conditions: a. Calculated shelf life in sealed bag: 12 months at < 40 °C and < 90% relative humidity (RH). b. Environmental condition during the production: 30 °C /60% RH according to IPC/JEDEC J-STD033C, paragraphs 5 through 7. c. The time between the opening of the sealed bag and the start of the reflow process cannot exceed 168 hours if condition b) is met. d. Baking is required if conditions b) or c) are not met. e. Baking is required if the humidity indicator inside the bag indicates a RH of 10% more. f. If baking is required, bake modules in trays stacked no more than 10 high for 4-6 hours at 125 °C. Recommended footprint and keepout We recommend that you use the following PCB footprints for surface-mounting. The dimensions without brackets are in inches, and those in brackets are in millimeters. XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 193 PCB design and manufacturing Recommended footprint and keepout While the underside of the module is mostly coated with solder resist, we recommend that the copper layer directly below the module be left open to avoid unintended contacts. Copper or vias must not interfere with the three exposed RF test points on the bottom of the module (see below). Furthermore, these modules have a ground plane in the middle on the back side for shielding purposes, which can be affected by copper traces directly below the module. XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 194 PCB design and manufacturing Flux and cleaning Flux and cleaning We recommend that you use a “no clean” solder paste in assembling these devices. This eliminates the clean step and ensures that you do not leave unwanted residual flux under the device where it is difficult to remove. In addition: n Cleaning with liquids can result in liquid remaining under the device or in the gap between the device and the host PCB. This can lead to unintended connections between pads. n The residual moisture and flux residue under the device are not easily seen during an inspection process. Rework CAUTION! Any modification to the device voids the warranty coverage and certifications. Rework should never be performed on the module itself. The module has been optimized to give the best possible performance, and reworking the module itself will void warranty coverage and certifications. We recognize that some customers will choose to rework and void the warranty; the XBee/XBee-PRO S2C 802.15.4 RF Module User Guide 195 PCB design and manufacturing Rework following information is given as a guideline in such cases to increase the chances of success during rework, though the warranty is still voided. The module may be removed from the OEM PCB by the use of a hot air rework station, or hot plate. Care should be taken not to overheat the module. During rework, the module temperature may rise above its internal solder melting point and care should be taken not to dislodge internal components from their intended positions.
