I’m developing an application with GPS and GSM on a GM862 and yesterday something really strange happend, and after a few days working the serial port just stops responding.
It recovers itself after 40 minutes.
What could do that?
One of the mistake that I did was not having a guardtime before and after escape sequence (+++), could be that?
ok, before and after escape sequence (+++) you have to put a guard time.
Anyway which is the firmware (at+cgmr)?
which is the at command sequence used?
