Hi Christopher,
I also tried the HE910 and had the same problem. In case a PIN is
required, the following solves the problem:
In /drivers/atmodem/sim.c, at_qss_notify()
case 2: /* PIN unlocked */
has to be changed to
case 3: /* SIM INSERTED and READY */
After the PIN was entered, we wait until the modem states that the SIM
is ready, i.e. #QSS: 3.
I haven't found a proper way to do this in case there is no PIN required.
We should only get to "post sim state" if we received #QSS: 3
The current work around is to signal sim_inserted only when you know it
is ready. This is less than ideal since oFono can read non-PIN
protected files from the SIM as soon as the SIM is inserted (e.g. ICCID,
EFpl, etc). However, the modem behavior is quite strange in this area.
Is it really unusual for a modem to deactivate the SIM in flight mode? I
had a look at some mobile phones and they seem to deactivate the SIM in
flight mode.
I've not seen one that turns off the SIM. After all, it would be pretty
inconvenient not to read SMS messages or access contacts, or mess with
MSISDN, or any other setting that is on the SIM.
Regards,
-Denis
