RE: Bluetooth Mesh Light Switch Example Provisioner DFU implementation fail.

This solved it. By moving the flash area used by dsm by defining DSM_FLASH_AREA_LOCATION in device_state_manager.c and setting it outside of the area of the bootloader the assert problem dissappeared. The serial problem was solved by removing the call to nrf_mesh_evt_handler_add. It's currently in test but it looks promising.

Thank you!

Hi Martin,

The first issue is caused by a limitation in the serial driver in the mesh, that makes it lock up when the host doesn't pop its outgoing packets. See the note in step 8 of the DFU quickstart guide. Only enable the serial module for devices that are actively communicating with the host. You can also remove the call to nrf_mesh_evt_handler_add in serial_handler_mesh_init() in serial_handler_mesh.c, if you only want the DFU module to push events to serial.

I believe the second problem happens because you've got other stuff in your flash manager regions. If you're adding your own flash manager before this mesh_stack_init call, that might be it, otherwise, check your flash configuration, and see if your app, bootloader or softdevice is using the same flash page for something else.
