I work on Q2687 module ,I succeded to make TCP connection but I have a problem with +CREG
the problem as follow:
1- I run my code and TCP connection is establised.
2- when the network is disconnected, I check AT+CREG? and I found the value +CREG: 0,0
3- the module is stuk at this value and I should reset the module to register to network agin
in berif, when the network disappears for litte time and comeback the value of CREG stuk at 0
and doesn’t back to 1 even network back and I need to reset the module
thanks and waiting your reply,
