I used many thousands of TC65i rev 01.100 without problems, now I need to use TC65i rev 02.004 (A-REVISION 03.000.20). I replaced the module with the new one but it doesn't register to the network (+CREG: 0,0).

Is it necessary to enable some feature by AT commands?

Hello,

Is the CREG 0,0 after restart also - that would mean that it is not searching for the network. Maybe it is in the airplane mode. Please check AT^SCFG? output - maybe there's the answer.

Regards,

Bartłomiej

Hello,

I solved the problem, the module ***** to receive AT+COPS=0, otherwise it doesn't find the network.

Thanks,

Alessio.

Hello,

This command chooses the automatic network selection.

Is it needed each time after booting? If so maybe the manual network selection was configured in the past and stored to the user profile which is restored after each boot.

Maybe you should try to restore the factory settings and then store to the user profile. Please check the commands AT&F, AT&V, AT&W.

Regards,

Bartłomiej
