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 a Micro-SIM card into J303; a NB-IoT USIM card should be selected;
6.
Connect the rod antenna with the SMA connector on J304 (RF antenna connector);
7.
Switch J302 (UART Switch) to the “MAIN UART TO MCU” state;
8.
Connect BC660K-GL-TE-B with STM32 Nucleo-64 board via the Arduino interface. Specifically,
connect J305, J306, J307 and J308 of BC660K-GL-TE-B with CN5, CN6, CN8 and CN9 respectively.
9.
Connect CN1 of STM32 Nucleo-64 board with your PC via a Mini USB cable. After powering on the
BC660K-GL module, the device information will be displayed on the “Device Manager” of the PC (as
shown in the following figure).
