Hi all,
Here are some robustness fixes for MBM modem.
In 1/2 I've corrected my older patches which tried to detect the presence of
the SIM card on the particular error response returned to AT+CPIN?. It did
not work as expected.
The patch 2/2 addresses problems initializing the modem too early. The
initial command tends to fail when a MBM modem is inserted via USB and oFono
tries to access the modem while it is still powering up and initializing
itself.
