Is it possible to use the NB-IoT device with BC66 chip, as external modem connected for example to arduino device over UART?
I have tried to do so, but I can't setup the proper communication.
Are all those ports usable, while powering the devkit board by the +5V_Ext pin? I'd like to be able to communicate with the devkit board using AT commands, that will be sent from the different module using serial port.
I need to connect them via UART, not over USB.
Hi,

According to the pinout - https://raw.githubusercontent.com/OLIMEX/NB-IoT/master/HARDWARE/NB-IoT-DevKit-pinout.png there are 3 pairs of RX/TX pins.
