This should be plugged into a PC USB port, a USB hub, or a main adaptor with a USB output. If a hub is used, it should be a powered USB hub to ensure that sufficient current is available at the port. The BT830 module can be driven by the available current at a USB port. The low noise LDO (U11) on the DVK-BT830 provides the 1.8V out to support the operating voltage configuration.

These can be used for an LED indicator or Wi-Fi and BT coexistence. The default setting on BT830 is to support Wi-Fi and BT coexistence. Further details on configuring the BT830 module for WLAN coexistence and LED status are available in the following application note:  BT830 Configuration File The oscillator Y1 provides a 32.768 kHz clock for deep sleep and other low-power modes. The pin descriptions of J12 are shown in Table 2. Table 2: J12 pin descriptions J12 Description Direction Pin-1 PIO[2] I/O Pin-2 PIO[0]/32K_CLK_IN I/O Pin-3 PIO[1]/BT_ACTIVE I/O Pin-4 PIO[4]/WLAN_ACTIVE I/O Pin-5 PIO[9]/BT_PRIORITY I/O Pin-6 GND Turn off the external 32 kHz oscillator by fitting a jumper on CON26. There are two LED indicators on the DVK-BT830. LED2 is connected to BT_PRIORITY/PIO[9]; LED3 is connected to WLAN_ACTIVE/PIO[4]. With default Pskey settings, the co-existence scheme is set to disable. Figure 2: Pin Headers - J12 and CON26 You can configure the PIO for other applications such as LED indicators for different connection stages (inquiry, connection, and transmission). For more information for PIO PSkey settings, see the BT830 documentation, found at the BT830 page: http://www.lairdtech.com/Products/BT830 5.2 PCM/I2S/SPI (PIN HEADER – J11) The DVK-BT830 has a 4-wire digital audio port capable of operating in PCM or I2S mode. The port also provides a debug SPI interface to the BT830 for use during test and development. Select between SPI and PCM using the PCM/SPI slide switch SW5 (Figure 3). The pin descriptions of J11 in PCM/I2S or SPI mode are shown in Table 3.

The default is USB. Figure 4: Pin Header J10 5.3.1 UART Interface Driven by USB   USB Connector. The development kit provides a USB Type mini-B connector (CON4) which allows connection to any USB host device. The connector optionally supplies power to the DVK-BT830 when SW4 is set to the USB position. The USB signals are connected to a USB to serial convertor device (FT232R) (Figure 5). USB – UART. The development kit is fitted with a (U9) FTDI FT232R USB to UART converter which provides USB-to-Virtual COM port on any Windows PC (Win 7 or later). Upon connection, Windows auto-installs the required drivers. For more details and driver downloads, visit http://www.ftdichip.com/Products/FT232R.htm.

In normal operation, the BT830 HCI interface is driven by the FTDI FT232R USB to UART converter.  Note: Before using the 4-wire UART through J10, place the jumper on CON2 to disable the function of FT232R. Figure 5: USB Connector (CON4) , FT232R (U9) , SW4 , and CON2 5.3.2 Pin Header J10 The pins of header J10 are detailed in Table 4. Table 4: J10 Descriptions J10 Description (PCM/I2S/SPI) Pin 1 GND Pin 2 Module_RTS Pin 3 NA Pin 4 Module_RX Input Pin 5 Module_TX Output Pin 6 Module_CTS Input Note: Direction Output For a 3-wire interface, you can leave RTS/CTS floating. You can use TX/RX and GND pin to access the module. 5.4 Operating Voltage Selection and Push Button Switch CON17 on the DVK-BT830 is used to toggle the operating voltage between 1.8V and 3.3V. This allows you to select a suitable I/O signal voltage level when the DVK-BT830 is connected to your platform. SW2 (push button TACT switch) provides a reset signal to reset the BT830 module (Figure 6).

For normal operation, CON1 must be fitted. Figure 7 shows the locations of SB9 and CON1. Note: This measures the current consumption of the BT830 series module only. Figure 7: Current measurement circuit To prepare the board for current measurement, cut the shorting of the solder bridge SB9. After this modification there are two primary ways to measure the current consumption:   Using Ammeter – Connect an ampere meter between the two pins of connector CON1. This monitors the current directly. Using Oscilloscope (Note) – Mount a resistor on the footprint R28. The resistor should not be larger than 10 Ohm. Connect an oscilloscope or similar with two probes on the pin on the CON1 connector and measure the voltage drop. The voltage drop is proportional with current consumption. If a 1 Ohm resistor is chosen, 1 mV equals 1mA. There is also a third way to measure current:  Using Current Shunt Monitor – The current drawn by the BT830 module can be monitored using the Current Shunt Monitor (CSM), INA216 (U8). The gain of INA216 is 200 V/V for lowest possible drop voltage. Note: The Current Shunt Monitor method allows the dynamic current consumption waveforms on oscilloscope as the BT830 radio operates. This can provide insight into power optimization. Embedded Wireless Solutions Support Center: http://ews-support.lairdtech.com www.lairdtech.com/bluetooth 9 © Copyright 2015 Laird.

I(mA) = Vmeas_TP14(mV) /51 CAUTION: Take care not to short TP14 (the Current Shunt Monitor IC (U8)) output to GND, as that will permanently damage the IC U8. 7 ADDITIONAL DOCUMENTATION Laird offers a variety of documentation and ancillary information to support our customers through the initial evaluation process and ultimately into mass production.
