I am using NCS V2.5.0.
I have managed to get the nrf/samples/bluetooth/mesh/light_ctrl sample working with DFU enabled by applying the attached overlay-dfu.conf.
I am able to perform a DFU, the application updates and works as expected. The issue I am facing is once my device was provisioned and I perform a DFU, the device starts up in an unprovisioned state. I have only made a small change to the application to be updated to, and the new application does not change any composition data.
Why is this and how can I resolve this issue?
