Current consumption
The F2MGXA module is power by dual voltages, one for logic and I/O, and the other for the FEM (Front End
Module, LNA / PA). These two voltages are connected separately externally but can be driven by one single
voltage regulator. Preferably, two separate voltage regulators should be used to minimize interference from
logic and I/O on the radio frequency signal. Due to the nature of Bluetooth®, switching between transmit
and receive, the regulator must be able manage fast changes in current consumption, not adding extensive
amount of noise.

5 Firmware versions
F2M03 is supplied with Bluetooth® stack firmware, which runs on the internal RISC micro controller of the
Bluetooth® module. This chapter includes an overview of the different options for more in depth
information please use separate firmware datasheets provided by Free2move.
All firmware versions are compliant with the Bluetooth® specification v2.0. The F2M03 software architecture
allows Bluetooth® processing to be shared between the internal micro controller and a host processor.
Depending on application the upper layers of the Bluetooth® stack (above HCI) can execute on-chip or on
the host processor.
Running the upper stack on F2M03 module reduces (or eliminates, in the case of a on module application)
the need for host-side software and processing time.
The integration approach depends on the type of product being developed. For example, performance will
depend on the integration approach adopted. In general Free2move offers four categories of Bluetooth®
stack firmware:
•
•
•
•
Wireless UART; offers a transparent interface to the Bluetooth® channel. There is no need for
additional drivers or Bluetooth® software on the host.
Embedded module solutions offer an application to run on the module. There is no need for an
external host (E.g. a Bluetooth® headset).
Two-processor solution involving a host and host controller, where the higher layers of the
Bluetooth® stack has to be implemented on the host.
Two-processor embedded solution offers a host with limited resources to gain access to a
Bluetooth® stack, with the higher layers on-chip, via a special API.
The protocol layer models for the different Bluetooth® stack firmware categories can be represented as
shown in the figures below.

Wireless UART
Free2move’s Wireless UART (WU) firmware is intended to replace the serial cable(s) connecting portable
and/or fixed electronic devices. Key features are robustness, high configurability, high security, low
complexity and low power. The WU firmware is compliant with the Bluetooth® Serial Port Profile (SPP) for
setting up emulated serial cable connections between connected devices. There is no additional need for
drivers or an external host with Bluetooth® software when using the WU firmware. When a successful
Bluetooth® connection is established the data channel and the voice channel can be used simultaneously or
separately. All information sent/received at the data/voice interface of the WU unit is exchanged
transparently via Bluetooth® with the connected remote device.
HCI (Standard Two-Processor Solution)
For the standard two-processor solution, where the split between higher and lower layers of the stack takes
place at the HCI, a complete Bluetooth® stack is needed in the external host. It is often preferable to use this
solution when the host is a personal computer of some description. However, in general this category can
include any computing platform with communications capability that is not resource limited.
Free2move do not offer a host stack.
Embedded Solution
This version of the stack firmware requires no host processor. All software layers, including application
software, run on the internal RISC processor in a protected user software execution environment.
The embedded solution can be used for a single chip Bluetooth product. One example is a cordless headset.
However this solution is equally applicable to any small wireless device that would benefit from a single
processor solution.
Free2move can offer among others the following single chip solutions upon a custom request*:
• Headset / Hands Free
• Human Interface Device; Mouse, keyboard etc (HID)
• Dial Up Network (DUN)
• Audio Gateway Profile (AGP)
• OBEX
• Onboard application (development of customer specific applications)
*Please consult your reseller for more information about custom firmwares.

Wireless UART architecture
The WU application runs on top of an embedded Bluetooth® v2.0 + EDR compliant stack, including protocols
up to the RFCOMM layer. Point-to-point connections are supported. This means that a unit running WU can
be either a master or slave unit.
The WU firmware offers one asynchronous data channel and one synchronous voice channel, both channels
capable of full duplex transmissions.
When a successful Bluetooth® connection is established the data channel and the voice channel can be used
simultaneously or separately. All information sent/received at the data/voice interface of the WU unit is
exchanged transparently via Bluetooth® with the connected remote device.
The WU unit is set to operate in a default mode that allows the user to communicate via the asynchronous
data channel over Bluetooth®, as soon as a successful connection has been established. This can be
achieved without sending any configuration commands to the WU firmware. However, as long as there is no
Bluetooth® connection established, it is possible to configure the WU firmware via hex commands
(described in the document Wireless_UART_protocol) or using a Windows configuration software.

5.1.1
General I/O
General I/O interfaces are used for different purposes between the WU firmware and the Host:
• Asynchronous data interface – configuration of the WU firmware or exchange transparent digital
information between the connected Bluetooth® devices.
• Synchronous voice interface – exchange transparent voice information between the connected
Bluetooth® devices.
• Bluetooth® connectivity PIO interfaces – indication and disconnection of the established
Bluetooth® connection.
• Emulate serial handshaking PIO lines interface – DTE or DCE serial handshake emulation between
the connected Bluetooth® devices.

While the handshaking lines are transparent to the data channel these I/O may also be used to transfer
digital signals between two Free2move devices running WU
Settings
The default settings allow the user to communicate via Bluetooth®, without sending any configuration
commands, as soon as a successful connection has been established. Information sent and received on the
serial interface of the WU unit at 38400 bps is transmitted transparently between the two connected devices.
The default settings are valid as long as the user has made no configuration.
When there is no Bluetooth® connection established it is possible to configure the WU firmware via
commands sent on the serial interface. All settings changed by the user are stored in persistent memory.
The following serial settings are used for configuration mode and are not configurable:

To be able to send commands to the Wireless UART firmware, it must be set in Host Controlled Mode (HCM).
As previously described the Wireless UART firmware can only enter HCM when no Bluetooth® connection is
established.
Once entered HCM there are several commands that can be issued:
• Configuration commands
• Software / Hardware reboot
• Inquiry (search for Bluetooth® devices in the neighborhood)
• Pairing (device security - authentication and encryption)
• Advanced configuration commands
• SCO commands
• Information commands
• Control commands
Configuration Commands
There are several settings stored in the Wireless UART firmware that can be read and modified by using the
configuration commands.
Examples of these settings are:
• Local Bluetooth® name
• Local SDP-service name
• Operating mode
• Serial port settings
• Bluetooth® security settings (authentication, encryption)
There are two normal operating modes:
• Connecting mode – Bluetooth® master
• Endpoint mode – Bluetooth® slave
In Connecting mode the Wireless UART firmware will continuously try to establish a Bluetooth® connection
to a specified remote Bluetooth® device in the neighborhood (Bluetooth® master).

13
In Endpoint mode the Wireless UART firmware may accept connections from remote Bluetooth® devices. A
connection request will be accepted when the specified rules are fulfilled (Bluetooth® slave).
Software / Hardware Reboot
This option gives the ability to be able to reboot the module via software commands.
Inquiry
Search for other Bluetooth® devices in the neighborhood.
There are three configuration parameters:
• How many seconds the search should be active
• A filter, used when searching for devices of as certain class
• The possibility to include the Bluetooth® name of the discovered devices
Pairing
When authentication is enabled, the devices must be paired before a successful connection can be
established.
The Wireless UART firmware can either initiate pairing with a remote device or accept pairing requests.
During a pairing PIN codes are exchanged between the local and remote device. A successful pairing requires
identical PIN codes. The result of the pairing attempt will be returned to the Host. If pairing was successful, a
unique link key has been generated and saved in non-volatile memory. The link key is used in the connection
establishment procedure for secure verification of the relationship between the paired devices.
The Wireless UART firmware allows the user to be paired with one device at a time. The last pin code entered
and link key generated are saved.
Advanced configuration
Includes among others commands for enabling power save modes, fine tune performance, enabling modem

Extra Functionality
The firmware extends the standard Bluetooth® functionality with the following features:
• Supports BlueCore Serial Protocol (BCSP) - a proprietary, reliable alternative to the standard
Bluetooth® (H4) UART Host Transport.
• Provides a set of approximately 50 manufacturer-specific HCI extension commands. This command
set (called BCCMD – “BlueCore Command”) provides:
o Access to the module’s general-purpose PIO port
o The negotiated effective encryption key length on established Bluetooth links
o Access to the firmware’s random number generator
o Controls to set the default and maximum transmit powers - these can help to reduce
interference between overlapping, fixed-location piconets
o Dynamic UART configuration
o Radio transmitter enable/disable - a simple command connects to a dedicated hardware
switch that determines whether the radio can transmit.
• The firmware can read the voltage on a pair of the module’s external pins (normally used to build a
battery monitor, using either VM or host code).
• A block of BCCMD commands provides access to the module’s Persistent Store (PS) configuration
database. The database sets the device’s Bluetooth address, Class of Device, radio (transmit class)
configuration, SCO routing, LM, USB and DFU constants, etc.
• A UART “break” condition can be used in three ways:
o Presenting a UART break condition to the module can force the module to perform a
hardware reboot.
o Presenting a break condition at boot time can hold the module in a low power state,
preventing normal initialisation while the condition exists.
o With BCSP, the firmware can be configured to send a break to the host before sending data
- normally used to wake the host from a Deep Sleep state.
• The DFU standard has been extended with public/private key authentication, allowing
manufacturers to control the firmware that can be loaded onto their Bluetooth® modules.
• A modified version of the DFU protocol allows firmware upgrade via the module’s UART.
• A block of “radio test” or Built-In Self-Test (BIST) commands allows direct control of the module’s
radio. This aids the development of modules’ radio designs and can be used to support Bluetooth®
qualification.
• Virtual Machine (VM). The VM allow development of customer applications on the module. Although
the VM is mainly used with “RFCOMM builds” (alternative firmware builds providing L2CAP, SDP and
RFCOMM), the VM can be used with this build to perform simple tasks such as flashing LEDs via the
module’s PIO port.
• Hardware low power modes: Shallow Sleep and Deep Sleep. The module drops into modes that
significantly reduce power consumption when the software goes idle.
SCO channels are normally routed over HCI (over BCSP). However, up to three SCO channels can be routed
over the module’s single PCM port (at the same time as routing any other SCO channels over HCI).

6 Device terminal description
6.1 UART Interface
The F2M03 Bluetooth® module’s Universal Asynchronous Receiver Transmitter (UART) interface provides a
simple mechanism for communicating with other serial devices using the RS232 standard(1).
Universal Asynchronous Receiver
Four signals are used to implement the UART function, as shown in the figure above. When F2M03 is
connected to another digital device, UART_RX and UART_TX transfer data between the two devices. The
remaining two signals, UART_CTS and UART_RTS, can be used to implement RS232 hardware flow control
where both are active low indicators. All UART connections are implemented using CMOS technology and
have signalling levels of 0V and VDD. UART configuration parameters, such as Baud rate and packet format,
are set by Free2move firmware.
Note:
In order to communicate with the UART at its maximum data rate using a standard PC, an accelerated serial
port adapter card is required for the PC.

The UART interface is capable of resetting the Free2move module upon reception of a break signal. A Break
is identified by a continuous logic low on the UART_RX terminal, as shown in figure below. If tBRK is longer
than a special value, defined by the Free2move firmware a reset will occur. This feature allows a host to
initialize the system to a known state. Also, the F2M03 can emit a Break character that may be used to wake
the Host. The above capabilities are not supported in the standard firmware, please contact Free2move for
more information.
Break signal
6.2 USB Interface
F2M03 contain a full-speed (12Mbits/s) USB interface, capable of driving a USB cable directly. No external
USB transceiver is required. The device operates as a USB peripheral, responding to requests from a master
host controller such as a PC. Both the OHCI and the UHCI standards are supported. The set of USB endpoints
implemented behave as specified in the USB section of the Bluetooth® specification v2.0+EDR. As USB is a
master-slave orientated system, F2M03 only supports USB slave operation.
Note: The USB interface can only be used with the HCI firmware
6.2.1
USB Data Connections
The USB data lines emerge as pins USB_DP (USB +) and USB_DN (USB -) on the package. These terminals are
connected to the internal USB I/O buffers of F2M03 and therefore have low output impedance. To match the
connection to the characteristic impedance of the USB cable, series resistors must be connected to both
USB + and USB -.
6.2.2
USB Pull-up Resistor
F2M03 features an internal USB pull-up resistor. This pulls the USB_DP pin weakly high when F2M03 is ready
to enumerate. It signals to the PC that it is a full-speed (12Mbit/s) USB device.
The USB internal pull-up is implemented as a current source, and is compliant with 7.1.5 of the USB
specification v1.1. The internal pull-up pulls USB DP high to at least 2.8V when loaded with a 15kΩ-5% pulldown resistor (in the hub/host) (when VDD=3.1V). This presents a Thevenin resistance to the host of at least
900Ω. Alternatively, an external 1.5kΩ pull-up resistor can be placed between a PIO line and D+ on the USB
cable. The default setting for the HCI-firmware uses the internal pull-up resistor.
6.2.3
Power Supply
The minimum output high voltage for USB data lines is 2.8V. To safely meet the USB specification, the
voltage on terminals must be an absolute minimum of 3.1V. Free2move recommends 3.3V for optimal USB
signal quality.
6.2.4
Self-Powered Mode
In self-powered mode, the circuit is powered from its own power supply and not from the VBUS (5V) line of
the USB cable. It draws only a small leakage current (below 0.5mA) from VBUS on the USB cable. This is the
easier mode for which to design for, as the design is not limited by the power that can be drawn from the
USB hub or root port. However, it requires that VBUS be connected to F2M03 via a resistor network (Rvb1
and Rvb2), so F2M03 can detect when VBUS is powered up. F2M03 will not pull USB + high when VBUS is off.

PIO

USB –
PIO[2] (USB ON)
Connections to F2M03 for Self-Powered Mode
The terminal marked USB ON is default PIO[2] in the standard HCI-firmware.
6.2.5
Bus-Powered Mode
In bus-powered mode the application circuit draws its current from the 5V VBUS supply on the USB cable.
F2M03 negotiates with the PC during the USB enumeration stage about power consumption. Bus-Powered
mode is not supported in the default firmware of the HCI-firmware
When selecting a regulator, be aware that VBUS may go as low as 4.4V. The inrush current (when charging
reservoir and supply decoupling capacitors) is limited by the USB specification (see USB 1.1 specification,
section 7.2.4.1). Some applications may require soft-start circuitry to limit inrush current if more than 10µF is
present between VBUS and GND.
The 5V VBUS line emerging from a PC is often electrically noisy. Regulation down to e.g. VDD=3.3V should
include careful filtering of the 5V line to attenuate noise that is above the voltage regulator’s bandwidth.
Excessive noise on the VDD supply pins of F2M03 may result in reduced receive sensitivity and a distorted
transmit signal. Recommended voltage regulator for the F2M03 is presented in section 6.7.

6.2.6
Suspend Current
USB devices that run off VBUS must be able to enter a suspended state, whereby they consume less that
0.5mA from VBUS. The voltage regulator circuit itself should draw only a small quiescent current (typically
less than 100µA) to ensure adherence to the suspend-current requirement of the USB specification. This is
not normally a problem with modern regulators. The entire circuit must be able to enter the suspend mode.
6.2.7
Detach and Wake_Up Signalling
F2M03 can provide out-of-band signalling to a host controller by using the dedicated control lines called
USB_DETACH and USB_WAKE_UP. These are outside the USB specification (no wires exist for them inside
the USB cable), but can be useful when embedding F2M03 into a circuit where no external USB is visible to
the user. Both control lines are shared with PIO pins and can be assigned to any PIO pin by firmware settings
(contact Free2move)
USB_DETACH, is an input which, when asserted high, causes F2M03 to put USB- and USB+ in a highimpedance state and turns off the pull-up resistor on USB+. This detaches the device from the bus and is
logically equivalent to unplugging the device. When USB_DETACH is taken low, F2M03 will connect back to
USB and await enumeration by the USB host.
USB_WAKE_UP, is an active high output (used only when USB_DETACH is active) to wake up the host and
allow USB communication to recommence. It replaces the function of the software USB WAKE_UP message
(which runs over the USB cable proper), and cannot be sent while F2M03 is effectively disconnected from the
bus.
USB_DETACH and USB_WAKE_UP Signal
6.2.8
USB Driver
A USB Bluetooth® device driver is required to provide a software interface between F2M03 and Bluetooth®
applications running on the host. Free2move don’t supply this driver.
6.2.9
USB 1.1 Compliance
The Bluetooth® chip on the F2M03 is qualified to the USB specification v1.1, details of which are available
from http://www.usb.org. The specification contains valuable information on aspects such as PCB track
impedance, supply inrush current and product labeling.
Although F2M03’s Bluetooth® module meets the USB specification, Free2move cannot guarantee that an
application circuit designed around the chip is USB compliant. The choice of application circuit, component
choice and PCB layout all affect USB signal quality and electrical characteristics. The information in this
document is intended as a guide and should be read in association with the USB specification. Independent

USB qualification must be sought before an application is deemed USB compliant and can bear the USB
logo. Such qualification can be obtained from a USB plugfest or from an independent USB test house.
Terminals USB+ and USB- adhere to the USB specification v2.0 (Chapter 7) electrical requirements.
For ac and dc specifications for terminals USB_DETACH, USB_WAKE_UP, USB_PULL_UP and USB_ON, refer
to section PIO specification.
6.2.10 2.0 Compatibility
F2M03 is compatible with USB specification v2.0 host controllers; under these circumstances the two ends
agree the mutually acceptable rate of 12Mbits/s according to the USB v2.0 specification.
6.3 Serial Peripheral Interface
F2M03 is a slave device that uses terminals SPI_MOSI, SPI_MISO, SPI_CLK and SPI_CSB. This interface is used
for program emulation/debug and IC test. It is also the means by which the F2M03 flash may be
programmed, before any 'boot' program is loaded.
Note:
The SPI signals should be routed out from the module if you need to upgrade the firmware on the module in the future
when the module is already soldered. It is highly recommended to route out the SPI-signals of the module for software
upgrade of the firmware!
Note:
The designer should be aware that no security protection is built into the hardware or firmware associated
with this port, so the terminals should not be permanently connected in a PC application. This interface is
not a user interface and only used for initial download and configuration of the firmware for the module.
6.4
I 2 C Interface
PIO[8:6] can be used to form a master I2C interface. The interface is formed using software to drive these
lines. Therefore, it is suited only to relatively slow functions such as driving a dot matrix liquid crystal display
(LCD), keyboard scanner or EEPROM.
Note:
The I2C interface is controlled by firmware specific settings. Please see specific firmware datasheet for information
PIO lines need to be pulled-up through 2.2k: resistors.
PIO[7:6] dual functions, UART bypass and EEPROM support, therefore, devices using an EEPROM cannot
support UART bypass mode.

6.5 PCM
Pulse Code Modulation (PCM) is the standard method used to digitise audio (particulary voice) for
transmission over digital communication channels. Through its PCM interface, F2M03 has hardware support
for continual transmission and reception of PCM data, thus reducing processor overhead for wireless
headset and other audio applications. F2M03 offers a bi-directional digital audio interface that routes
directly into the baseband layer of the on-chip firmware. It does not pass through the HCI protocol layer.
Hardware on F2M03 allows the data to be sent to and received from a SCO connection. Up to three SCO
connections can be supported by the PCM interface at any one time(1)
F2M03 can operate as the PCM interface Master generating an output clock of 128, 256 or 512kHz. When
configured as PCM interface slave it can operate with an input clock up to 2048kHz. F2M03 is compatible
with a variety of clock formats, including Long Frame Sync, Short Frame Sync and GCI timing environments.
It supports 13 or 16-bit linear, 8-bit µ-law or A-law companded sample formats at 8ksamples/s and can
receive and transmit on any selection of three of the first four slots following PCM_SYNC. The PCM
configuration options are enabled by firmware settings (contact Free2move).
F2M03 interfaces directly to PCM audio devices includes the following:
Qualcomm MSM 3000 series and MSM 5000 series CDMA baseband devices
• OKI MSM7705 four channel A-law and µ-law CODEC
• Motorola MC145481 8-bit A-law and µ-law CODEC
• Motorola MC145483 13-bit linear CODEC
• Winbond W681360R 13-bit linear CODEC
• STW 5093 and 5094 14-bit linear CODECs
• F2M03 is also compatible with the Motorola SSITM interface

6.5.2
Long Frame Sync
Long Frame Sync is the name given to a clocking format that controls the transfer of PCM data words or
samples. In Long Frame Sync, the rising edge of PCM_SYNC indicates the start of the PCM word. When F2M03
is configured as PCM Master, generating PCM_SYNC and PCM_CLK, then PCM_SYNC is 8-bits long. When
F2M03 is configured as PCM Slave, PCM_SYNC may be from two consecutive falling edges of PCM_CLK to half
the PCM_SYNC rate (i.e., 62.5µs) long.
Long Frame Sync (Shown with 8-bit Companded Sample)
F2M03 samples PCM_IN on the falling edge of PCM_CLK and transmits PCM_OUT on the rising edge.
PCM_OUT may be configured to be high impedance on the falling edge of PCM_CLK in the LSB position or on
the rising edge.
6.5.3
Short Frame Sync
In Short Frame Sync the falling edge of PCM_SYNC indicates the start of the PCM word. PCM_SYNC is always
one clock cycle long.
Short Frame Sync (Shown with 16-bit Sample)
As with Long Frame Sync, F2M03 samples PCM_IN on the falling edge of PCM_CLK and transmits PCM_OUT
on the rising edge. PCM_OUT may be configured to be high impedance on the falling edge of PCM_CLK in the
LSB position or on the rising edge

Multi-Slot Operation
More than one SCO connection over the PCM interface is supported using multiple slots. Up to three SCO
connections can be carried over any of the first four slots.
Multi-slot Operation with Two Slots and 8-bit Companded Samples
6.5.5
GCI Interface
F2M03 is compatible with the General Circuit Interface, a standard synchronous 2B+D ISDN timing interface.
The two 64Kbps B channels can be accessed when this mode is configured. In the GCI interface two clock
cycles are required for each bit of the voice sample. The voice sample format is 8-bit companded. As for the
standard PCM interface up to 3 SCO connections can be carried over the first four slots.
GCI Interface
The start of frame is indicated by PCM SYNC and runs at 8kHz. With F2M03 in Slave mode, the frequency of
PCMCLK can be up to PCM_SYNC In order to configure the PCM interface to work in GCI mode it is necessary
to have the correct firmware support (contact Free2move)

6.5.6
Slots and Sample Formats
F2M03 can receive and transmit on any selection of the first four slots following each sync pulse. Slot
durations can be either 8 or 16 clock cycles. Durations of 8 clock cycles may only be used with 8-bit sample
formats. Durations of 16 clocks may be used with 8, 13 or 16-bit sample formats.
F2M03 supports 13-bit linear, 16-bit linear and 8-bit µ-law or A-law sample formats. The sample rate is
8ksamples/s. The bit order may be little or big endian. When 16-bit slots are used, the 3 or 8 unused bits in
each slot may be filled with sign extension, padded with zeros or a programmable 3-bit audio attenuation
compatible with some Motorola CODECs.
6.5.7
Additional Features
F2M03 has a mute facility that forces PCM_OUT to be 0. In Master mode, PCM_SYNC may also be forced to 0
while keeping PCM_CLK running (which some CODECS use to control power-down)

6.6 PIOs
The F2M03GXA have 10 programmable general-purpose I/O ports PIO[11:2] and two analog I/O ports
AIO[1:0]. PIO lines can be configured through software to have either weak or strong pull-ups or pull-downs.
All PIO lines are configured as inputs with weak pull-downs at reset.
AIO[1:0] functions available via these pins include an 8-bit ADC but can also be used as general-purpose I/O
lines. Typically the AIO[0] is used for battery voltage measurement. The voltage range for AIO[1:0] is
constrained by the internal analogue supply voltage which is 1.8V.
Note:
The PIO and AIO lines are controlled by firmware specific settings. Please see specific firmware datasheet for information
about the PIOs used!

Power supply
The power supply for the F2M03GXA should be chosen carefully. Bad power supply can reduce the
performance and may damage the module. Please use the recommended voltage regulator or consult
Free2move if using another regulator. It is also essential to use a proper reset circuit to the module for
correct operation.
6.7.1
Voltage regulator
The F2M03GXA have two power supplies, +V_PA and +VCC.
It is recommended to use two separate voltage regulators for best performance but it is possible to use only
one regulator if the design is made carefully. The voltage supplied should have low noise, less than 10mV
rms between 0 and 10MHz. The transient response of the regulator is also important. At the start of a
Bluetooth packet, power consumption will jump to high levels. The regulator should have a response time of
20µs or less; it is essential that the power rail recover quickly.
+V_PA is feeding the external PA and is in need of high current with low noise.
+VCC is feeding the internal circuits (Bluetooth chip and memory).
The power supply for +V_PA and +VCC should have less than 10mV rms noise levels between 0 to 10MHz. The
recommended voltage regulator is: TPS73633DBVTG4 from Texas Instrument
6.7.2
Reset
The F2M03GXA has an active low reset (pin nr: 35). The reset pin MUST be connected to either a reset-circuit
(voltage monitor) such as the TC1270ASVRCTR, MAX811S, DS1818 or using an I/O from a microcontroller.
Reset cannot be done with a R-C network. It is recommended to use one of the reset circuits mentioned
above. Special considerations must be taken when using an I/O from a microcontroller; a pull-down resistor
(1.8kΩ) must be placed on the I/O-line.
It is recommended that RESET is applied for a period greater than 5ms.
At reset the digital I/O pins are set to inputs for bi-directional pins and outputs are tristated. The PIOs have
weak pull-downs.

7.2
Layout guidelines
The module uses bottom pads for soldering optimized for an automatic solder line. It is also possible to
solder the module manually by using hot air soldering. For manual soldering solder pads may in some
situation be made slightly larger to allow easier heating process.
To achieve good RF performance it is recommended to place ground plane(s) beneath the module but not
under the antenna. The ground planes should be connected with vias surrounding the module. Except from
the ground plane it is preferable that there are as few components and other material as possible nearby the
antenna. Free air is the best surrounding for the antenna.
All GND pads must be connected directly to a flooded ground-plane. If more then one ground layer is used
then make a good connection between them using many via holes. +VCC and +V_PA should be connected to
the LDO using a wide trace.
