Can't initiate ping in nRF9160 to one APN.

[olegtk1]

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

Hello Oleg,

What are your NCS and Modem FW versions?

Also, do you have the original .bin/.mtrace modem traces as well?

Best regards,

Hi Michal.

Thanks for Your response.

This is Modem FW version:

I am not sure if it is NCS:

I will ask Customer for original .bin/.mtrace .

We are planning another log collection session with Customer.

Would You suggest please if anything else is needed except Trace Collector logs?

Ah, I am sorry then, thought that it was compiled on your computer.

Sorry, many different cases and it's easy to get confused sometimes.

Those are some weird issues. I would have thought about hardware issue, but now you have tested it on two DKs at least...

Could you test it on another computer? At least connecting to the serial port. If you are using USB hub by chance, maybe try to connect it directly.

Best regards,

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?

Hi Michal.

I opened new case 332988 "nRF Connect for Desktop (v5.0.2) cannot detect our nRF9160 Development Kit".

This case can be closed.

Thank You very much for support.
