Hi Terje,

Thanks so much for the feedback, I can confirm that this does indeed resolve the issue I was experiencing.

If everything was this easy:P

Have a good day.

Hi,

I am very sorry for the delays.

It turns out, if you do the DFU from the nRF Connect Device Manager app, the smartphone application will erase application data by default. You can enable this in the app, through the settings for Firmware Upgrade. Disable the "Erase application settings" checkbox, after which upgrades should preserve the provisioning data through the upgrade.

Regards,
Terje

Hi Tsec, thanks for getting back to me.

So the light example is actually where I got the fragment from. I tested the mesh light example and I am seeing the exact same behaviour.

I have not seen this with NCS v2.3.0, only with 2.5.0.

Hi,

It sounds like a situation where the configuration data of the node is erased or corrupted. Have you done the same successfully with the Bluetooth mesh: Light sample, which should work with BLE DFU according to the documentation?

Terje
