3.2.2. Operation Procedure When Using Multi Boards
1. Install driver for STM32-Nucleo board, which can be downloaded from the following address:
2. Install USB-UART driver, which can be downloaded from the following address:
https://www.ftdichip.cn/Drivers/VCP.htm;
3. Remove 0
Ω
resistors of SB13 and SB14 with soldering iron, and then solder them onto SB62 and
SB63 respectively;
4. Short-circuit pin 1 and pin 2 of CN2, pin 3 and pin 4 of CN2, pin 1 and pin 2 of JP5 and pin 1 and pin 2
of JP6;
5. Insert Micro USIM card (NB-IoT/GSM card) into J401, or insert Micro USIM card (NB-IoT card) into
J402;
6. Connect rod antenna with SMA connector on J301;
7. Switch UART_SWITCH J304 to “MAIN UART TO MCU” state;
8. Connect Arduino interface to STM32-Nucleo board, and connect J307, J309, J311 and J310 of
BC92-TE-B to CN5, CN6, CN8 and CN9 respectively;
9. Connect CN1 of STM32-Nucleo board with PC via Mini USB cable, and switch S201 to “ON”. After
powering on BC92 module, device information will be shown in the device manager on PC.
