I use OAT 3.10 and OS 6.55 with Q2501B.
The problem is that when i lanch AT+CREG=1 throgh adlcmdCreate to activate registration unsolicited responses. i receive OK and i subscribe for this reponses (+CREG:…) but i receive anything after !!!
And when i try the AT command in HyperTerminal AT+CREG? i havve the reponse +CREG:0,1 means that the unsolicited responses are not activated !!!
