Checking the Status of the GSM Login
The INSYS GSM 4.3 logs in into the GSM network automatically with each restart
of the device. The login status into the GSM network may be requested for test
purposes. Then, you can see, whether the INSYS GSM 4.3 is logged out at the
moment, whether a network search is performed, whether a login has been re-
fused by the GSM network, or whether the device is logged in into a foreign net-
work via roaming.
Configuration with HSComm
The Login state is indicated in text form in HSComm on the “Basic Set-
tings” tab in the “GSM Connection” panel under “PIN active”.
Configuration with AT commands
In order to request the Status of the GSM
login, use the command
AT+CREG?
The Status is indicated in the reply by the second number following the
comma.
Reply example
