When not running an OpenAT application can you send AT commands to both UARTs on a Q24plus?
I have always assumed that you can, but have not been able to try it because I don’t have a set up that connects to both UARTs on the connector.
What I would like to be able to do is plug a Q24plus into a PCB that has a USB to serial chip on it and gives you 2 USB serial ports, one for the data connection and once for checking the signal quality and sending/receiving SMS - all without using multiplexing (AT+CMUX). Does anyone know if anyone makes something like this?
Does the USB IESM let you do this?
