ModemManger behaves strange

[Vanja Žerić]

Hi,

thanks for the answer, I saw your thread, but for me it is strange because AT command does not return SIM PIN2 but READY, but reading with library returns that SIM PIN2 is required.

BR,
Vanja

Hello,

I had the same question a while ago, and found an explanation:

Hello everyone,

I am working with some USB Connectivity Module and I am using ModemManager to get status of SIM PIN. When I am using C app that is using ModemManager library and when I extract status of SIM PIN, I am getting that SIM requires PIN2 (MM_MODEM_LOCK_SIM_PIN2), but when I send AT command I am getting that SIM is READY, that means that SIM is unlocked. SIM is connected correctly, but it seems only that message is wrong.
After calling test app:

After calling AT command:

I am getting correct PIN status messages if SIM requires PIN or PUK, I tested it, but when I send correct PIN, SIM connects, but PIN status message is that SIM requires PIN2.

This is how I am extracting the status:
This is prototype of my function:

This is how I extract status in that function:

Hal_modem_pin_status_enum convert MM PIN status to my enum…

Does anyone has any idea?
