Hi, I'm searching a way to keep monitored the registration SIM into GSM modems. I found the way to send the AT command "AT+CREG?" at every keepalive...I could monitor the log file and when I see an "+CREG: 0,x" (where x is 1 or 5) all is fine. If I see other value, i will catch an alert to my monitoring system.
There is a best way to do this? Thanks M.
