Provisioning error in Light Switch server (NRF52832)

[Dmitro Balo]

Hello! I am trying to run the "Light switch" example on a custom board.

My environment:
- nRF5 SDK v17.0.2
- nRF5 SDK for Mesh v5.0.0
- SoftDevice S132 v7.2.0
- NRF52832_xxAA (on custom board)
- Keil uVision 5.33.0 (Compiler v5)
- J-link debugger
- nRF Mesh App v3.1.6 for Android

I'm using Keil's built-in MDK. When trying to add a device to the network, nRF Mesh reports an error:

The example code remained unchanged, except for the fact that I commented out all calls related to the board (controlling the LEDs). After the error occurs, my log looks like this:

While debugging, I was able to figure out that the "m_device_provisioned" flag is set to "true" at this location:

However, after that, the GATT connection is closed, as evidenced by the call to the "a_link_close_notify" function, which informs subscribers about the NRF_MESH_PROV_LINK_CLOSE_REASON_ERROR error:

Call stack up to this function:

When compiling the project, I see that some of the declared sections do not have observers registered, but the project starts successfully:

I hope for your help!

Hi Dmitro, 

Do you have the same problem if you try to compile and flash the example on a DK (unmodified example) ? 

Could you also check if you have the sdh_* section defined in the flash_placement.xml file ?

Sometimes we have the issue that the connection between the phone and the fresh provisioned device and you will need to manually connect and do configuration as showed in your screenshot: 

If the issue remains, please send us your project so we can test here.
