Hello,

Are there plans to support RLC UNACK with nRF9160? If not, why? Traditionally/generally RLC UNACK seems to have been supported also within LTE Cat M1.

Hello,

So the expert was able to reproduce what you see, and the first screenshot is because of incorrect RLC mode in the “default bearer” setting which you seemingly have solved in the second screenshot.

Furthermore, he instructs:

If you press “Connect” button in the 2^nd screenshot, RLC mode needs to be ack also in the pop-up window or in test mode dedicated bearer in GUI config menu (depending on callbox version).

But if you are directly trying to connect to the internet and get RRC connection reconfiguration error (around 20 seconds after attaching), can you save the configuration (with soft button) as a *.dfl file and attach to this ticket. This way, we can try here. Or if possible send tester / UE logs.

It would also help to know what procedure you are trying after attach.

Thanks!

I'm sorry, I do not have any details on this. Will need to forward your question to our CMW500 expert.

Hi. Does this RLC setting address the RCC error mentioned above? Or the first which the link acknowledge was changed to get to the second RCC error?

Based on your first screenshot, it looks like the CMW500 is configured to RLC UNACK which the nRF9160 does not support. Can you please reconfigure to RLC ACK:

Connection->default bearer : Change from RLC UM to RLC AM

Thanks!

Kind regards,
Øyvind

Hello,

Sorry for the late reply, I have been out of the office for the last days.

The technical support team does not work with R&S CMW500 that much, so I will need to contact one of our experts and see what they recommend.

Kind regards,
Øyvind
