I have an issue in being unable to recive the URC message from the modem whenever it receives an SMS.
I know that it receives them since i can find and read them if I use AT+CMGL but, i don't receive any notification when the modem gets them. I played around with the URC related commands but I've been unable to get it to work (other URCs work fine).
The modem is a BG600L M3 from Quectel and following is the sequence of commands i'm sending ("AT" is always omitted and the first command is literally "AT\r", basically an empty one).
