@Capstone-0 Our drone crashed and we ditched our project but has ModalAI added support for AT commands for the 5G (I assume EM9291) modem yet? If not, I figured out how to do it and posted instructions here

Once you get those commands, you can set up a service to query the modem for its signal strength and pump the output somewhere. Someone else in that forum discusses it a bit.
