GL865 and network registration

  1. Hi, while trying to register to the GSM network, I do continuous success test by issuing AT+CREG? commands repeatedly.


    Is there a "penalty" for doing so too frequently? I mean, does asking for registration success actually interfere with the ongoing registration process on the SIM?


    What would be an optimal rate of asking AT+CREG? until final success?



    1. I don’t think there are problem if you respect the timings described in AT Commands reference Guide and of course wait for the answer after each query.
