Differing behavior between DKs when running sid_end_device sample

[mbprx]

Hello,

I've been playing with an nRF54L15 PDK, specifically with the sid_end_device sample. I was having a lot of trouble getting the device to register/connect to Sidewalk using the DUT example. However, when I flashed the exact same sample to my nRF52840DK and provisioned it with the same certificate, it succeeded in registering and connecting. I then tried a separate nRF54L15 PDK, and it also worked. Is it safe to assume that there may be a hardware issue with the first PDK? Is there anyway I could validate that for sure?

For example, the first PDK just hangs here after calling "sid start":

Hi Miles, I will check inn with our sidewalk team and get back to you. I see the setup do not say anything regerdaging PDK/DK V0.8.1 or higher so I need to check if there is anything specific there.

Hi Runar,

Just checking back -- any word from the sidewalk team?

[runsiv]

Hi and sorry for the delay

I could not get any good explanation for what was the issue with the board on question. The only thing I can think (and this is just speculation on my end) is that the same provision file was used for two devices at the same time. But this would not however explain why it worked on the next 54l15.

Hey Runar,

I thought that as well, but ran into the same trouble with a different provisioning file. Nothing I've tried has successfully returned the sample back into working condition. Everything seems to be normal, except that it won't register any more after the board configurator step. Our sales rep sent us two more DKs, so I may see if I can replicate it with more explicit & traceable steps. If I do, I'll open a separate ticket. 

Thanks,

Miles

That sounds great. I hope it will not be the case but if it happens again please make a ticket

Regards

Runar
