Provision does not work for one board. Stuck in identifying phase.

[Pascal__]

I have a strange problem. I have two nRF52840 DK boards and I build an application on top of the light switch example. One board works fine, but on the other board stuck in the identifying phase while provisioning. This happens with my application and even with the original light switch example. I am using the mesh app for provisioning.

I also tried the blinky example which works fine on this board. 

I cannot make difference in the settings of the two boards. But is there maybe something that I could try? Or is it maybe a hardware issue?

Hi Pascal, 

Do you see the LEDs blink when you click identify ? 

Could you check if there is any crash/assertion when issue happens  ? Could you check the RTT log ? 

You can add a breakpoint inside device_identification_start_cb() to see if that is called. 

Have you tried to use another phone ? 

You can also try to do provisioning from one of the DK to that DK by using the provisioner project.

The identification was not the problem. Just the provision step. 

But somehow, the board just works again today.
