Hi there,
I have a problem with my GM862-GPS.
I managed so far interfacing it with an ATmega8. What works:
* switching it on and off
* initializing it
* pulling gps position through the AT command AT$GPSACP (second serial port is unused)
* sending position as SMS.
Now I try to do these things in a loop.
The problem is, that after sending the SMS, further AT commands only are echoed, but no "OK" or error is returned. It is not a problem of the microcontroller as I have checked it with a direct PC to GM862 serial communication.
Any hint, someone?
Cheers,
Alex
