Can't initiate ping in nRF9160 to one APN.

Hi.

In our private network we experience one problem.

We can ping Google (8.8.8.8) via APN customer4. In Wireshark traces it is seen that ping is initiated.

On RRC level Control plane service request is initiated, and ping is run successfully.

When we change APN to internet, we can see that ping is not initiated, UE turns into RRC-IDLE state after expiration of inactivity timer.

And we can see error-22 at terminal session.

Can somebody prompt what can be a reason for such fails?

Thanks,

Oleg

  • Hi Michal.

    After some exercises with our modems by other group engineers we have another problem now.

    Application nRF Connect for Desktop (v5.0.2) cannot detect our nRF9160 Development Kit.

    Quick Start can't detect it:

    In logs I can see this info:

    Programmer does not recognize device as nRF9160 DK:

    And I can't flash:

    Would You be so kind as to suggest what can be done in our situation?

    Best Regards
