My MBM seems to only detect the SIM if it is inserted during the modem
enumeration (on USB or PCI). If you there's no SIM during modem
initialisation, or you extract the SIM, then inserting a new SIM is
never detected, the modem will always return "SIM not inserted" until
Yes, most modem don't support dynamic detect SIM.
Caiwen, have you looked at drivers/atmodem/sim-poll.c?
I have read drivers/atmodem/sim-poll.c. It looks very good.
I have two questions.
1. It seems it depends on the invoking of ofono_sim_register to trigger the SIM status
Polling. I'm not sure whether it is allowed to register the APIs(invoke
before make sure the SIM is inserted.
2. According to the modems that I used previously, it seems it is required to send profile
to SIM before fetch the first STK command. It just my guess, I don't test it. If
please correct me.
Here I suggest put STK initialization(fetch the SET UP MENU command) in SIM state watch,
Because it is also required to fetch SET UP MENU command after unblock PIN or REFRESH
