I am trying to evaluate the BC-G module but I am not able to get the module connected to a cell.
I am able to readout the IMSI of the SIM card by using the AT+CIMI command. Autoconnect is enabled and the UE is powered on but the module does not seem to receive any signal (see output of AT+NUESTATS=RADIO).
Do I need to send any other command to manually activate the radio of the module so that the NUESTAT command outputs valid signal information?
Hardware setup:
- MIKROE 3294 NB IOT CLICK breakout board with BC95-G modem
- LTE NB-IoT antenna
- SIM4IOT LTE NB-IoT capable sim card with national/international roaming
