Is there a simple way to list the signal strength on all available networks?
It looks like it should be possible to do AT+COPS=? to get the list of available operators, then select each one in turn (ignoring any “network not allowed” errors) and do AT+CSQ to find its signal strength…
Would this work?
Is there a simpler way?
Is there a command that returns the list of operators with the signal strength for each one?
