fibocom: Monitor connection status using +GTRNDIS?
In situations where the configured APN for the initial EPS bearer
(cid=1) does not match the APN for the actual connection, ModemManager
sets up a context (cid!=1) with the proper APN when connecting. If the
APN for the initial EPS bearer was not valid, the SIM may fall back to a
default one. If that default matches the APN for the proper connection,
the initial EPS bearer is re-used for the actual connection. In that
scenario, +CGACT? will report deactivated for the actual connection
context (cid!=1). ModemManager subsequently reports the connection as
disconnected.
+GTRNDIS? will always reflect the correct state for the context ID we
used to set up the ECM connection. Hence, it makes sense to use this
command to assess the connection status.
This has been tested with the MA510-GL modem module.
