Hello again, and thank you for your patience.

We are using the Laird dongle for PTS testing, with latest version of PTS.

On the IUT side we use 52840 DKs running mesh stack in nRF Connect SDK. The core mesh stack itself resides in zephyr repo and it is tested using tester application that is located here.

This tester application runs on the 52840 DK as IUT.

Regards,

Elfving

Hi,

Can you please specify which hardware/controller/dongle you are using on Stack side and on PTS end.

Regards,

Harsha

Hello again, I just got some additions to this from our Mesh R&D team.

If PTS and IUT both are run on the same computer, it is possible that you will have a lot of packet loss due to how driver handles two dongle at the same time. If you are running on different computers, it is possible there are issues with driver integration with the stack. Unfortunately, we don't have such testing configuration setup, so we don't know much about this in the mesh team.

Though we do not see issues with PTS packet losses (when used for testing the NCS mesh stack running on hardware) in our internal testing.

Elfving

Hello,

This doesn't immediately seem mesh related to me. Are you seeing the same issue using some like the radio test sample?
