ICCID not requested when PIN is locked

ICCID not requested when PIN is locked

Hi all,
I have a problem with SimManager interface.
When I start ofono with pin locked it starts to read the sim file manager
but the first message fails:

ofonod[29427]: Aux: > AT+CRSM=192,12258\r
ofonod[29427]: Aux: < \r\n+CME ERROR: 4\r\n

The callback of this message contains the following call which would
success but it is never called because of the error.

This results in the problem that ICCID is never retried even if I enter the
pin.

How can I solve this problem?

​Thank you!

Enrico

This is a modem firmware problem.  The ICCID request should always 
succeed, even if the PIN is locked.

You can disable the PIN, or power-cycle the modem.

You can also add code to try re-reading the ICCID when PIN is entered. 
Patches are always welcome.

Thank you!

You can always try to read ICCID again after the PIN has been retrieved 
if the ICCID is missing.  e.g. something like:

if (sim->iccid == NULL)
	sim_iccid_changed(SIM_EF_ICCID_FILEID, sim);

in sim_initialize_after_pin()
