    Hi, im working with A6 GSM/GPRS module V03.03.20160830011H03, and I have a weird trouble. As a context, i can already send SMS and make calls with this device, now im trying to connect to gprs, just that, only establish a connection.

    Its a weird situation becouse some times works and other just dont, i noticed something odd in AT+CGATT=1 command, some times takes so much time or dont answer, (command dont responds! message) and when that happend the AT+CGACT=1,1 responds with “error 148”.

    In case AT+CGATT=1 command has responded quickly “OK” then the command AT+CGACT=1,1 is accepted and a connection is established.

    Im entering this commands….

    ATrn

    AT+CPIN=”1721″rn

    AT+CGATT=1rn

    AT+CGDCONT=1,”IP”,”web.vodafone.de”,,0,0

    AT+CGACT=1,1

    Thanks a lot, I hope you can tell me something to fix the problem.
    Have a nice day.
