Since the Nordic nRF52832 microcontroller on the RAK8212 board has only one hardware UART and it is connected to the main UART interface of the bg96 which, according to Quectel, can only be used for AT command communication, then how is it possible to send gsm data to the Nordic MCU?
What do you mean about sending GSM data to Nordic MCU? The GSM data comes from BG96 or not?
If it comes from BG96, the data can be sent to MCU through uart interface surely. If not, i don’t know what it is, but we normally send some data or command into Nordic MCU through BLE.
