Notify user of low signal strength as error

[Frijol]

Currently difficult to identify errors– is the code wrong, the module, or just not enough service?

Is there a way to expose the received signal strength to make this more debuggable?

you mean other than 'at+csq' that reports the RSSI?

Fair point, but first-time users of the GPRS module don't know about the at+csq command, and I think those are the people who are most confused if their module works.

Maybe this would be best addressed with better example code. Similar to the example code for GPS, which shows the user how to log information re "satellites in view" vs "fixed" vs actually getting the coordinates (http://start.tessel.io/modules/gps).
