Tips and questions relating to the GPS modules from SFE
By smalcom

Script on module:
>>> AT+CGDCONT=1,"IP","my_apn"
<<< OK
>>> GPRS=1
<<< +CME ERROR: activation failed

but if at this time(script still working and got errors) in another port(with TelitMUX) i type the same:
>>> AT+CGDCONT=1,"IP","my_apn"
<<< OK
>>> GPRS=1
<<< GPRS: 1
<<< MY_IP

whats wrong?

Add: Heh. solved. When modem get settings from remote server(my own) it incorrect parse packet and locally save string: 0x12 (and MyAPN) after reboot this APN applied and result - error. Ok, its a stupid bug, but... but im happy because found them.
