Does that mean I need to develop my application using Mesh DFU example code, any other mesh application like light_switch server/client won't work directly right?

Hi Bhavit,

Your comment was right. When you update ble_app_blinky , the app doesn't support Mesh DFU so that's why it wouldn't allow you to do another DFU.

You would need to implement Mesh DFU as we did in the \examples\dfu example.

I'm not sure why you want to update a non-mesh application to mesh node.

If you want to switch from application to the bootloader to do a DFU you would need to assign NRF_POWER->GPREGRET = 0x00. Please have a look at file main.c of the \mesh\bootloader to see how it works.

It looks like for the time it was already in DFU mode that why it is happening but after 1st time it was running the application that's why it has to go in DFU mode but it is not going.
