3.2.2. Operation Procedures of Using Multi Boards

1. Install driver for STM32-Nucleo board, which can be downloaded from the following address:

http://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mcu-eval-to

ols/stm32-mcu-eval-tools/stm32-mcu-nucleo/nucleo-l476rg.html;

2. Install USB-UART driver, which can be downloaded from the following address:

https://www.exar.com/product/interface/uarts/usb-uarts/xr21v1412;

3. Remove 0 ohm resistors of SB13 and SB14 by soldering iron, and then solder them onto SB62 and

SB63 respectively;

4. Short-circuit pin 1 & 2 of CN2, pin 3 & 4 of CN2, pin 1 & 2 of JP5 and pin 1 & 2 of JP6;

5. Insert Micro USIM card into J203, please choose an appropriate USIM card according to hardware

versions of BC95 module.

6. Connect rod antenna with SMA connector on J208;

7. Switch

“

UART_SWITCH

” to “BC95 TO MCU” state;

8. Connect Arduino interface to STM32-Nucleo board, and connect J202, J204, J205 and J207 of

BC95-TE-B to CN6, CN8, CN5 and CN9 respectively.

9. Connect CN1 of STM32-Nucleo board with PC via Mini USB cable. After powering on BC95 module,

device information will be shown on the device manager of PC.
