I try to simulate a connection loss by disconnecting the antenna after a valid ppp connection has been set up.
After reconnecting the antenna, activating a context again and trying to set up a ppp connection, the modem always sends
+CGEV: ME DEACT IP, , 1
and the ppp connection fails.
Why do I get this URC? Am I doing something wrong? It seems as if IP Control Protocol is failing and the modem cannot receive IP configuration from the network. IP phase is deactivated by the modem.
I have attached a full debug output.
The basic steps I take to set up a ppp connection after network registration:
I also use AT&C0 to disable data carrier detect. When the DCD is disabled the modem does not hangup anymore after the data connection.
Thanks in advance!
