My module can not catch +CREG: 2 response!
Simply, my module registers gsm network. When module receives +CREG: 2 unsolisited response(gsm disconnection) it logs a record accourding to the event. When i able to read the logs today, i see that module established gsm registration on 3rd of September but catched +CREG: 2 response on 8th of September! Between 4th-8th i could not connect my module by gsm(call).
So i think that module can not catch gsm unregistration and it still thinks that gsm connection is alive. And this state takes even 5 days!
I suspect that this stuation happens on a particullar area. Because these kinds of problems happens most in a particular city. So that makes me think the problem can be related to the gsm network.
I want to know that anyone experiences the same stuation and how to make a solution.
Module: Airprime Q2687RD, FW: R7.43
Edit: not gprs it is gsm.
