RE: Booting Mesh-Application from BLE secure Booltoader

Hello Roland,

I just did a test with the light_switch\proxy_server example, where I created a DFU image with this, and used the secure_bootloader from SDK15.0.0, and it worked on my computer. I didn't do any changes to either the bootloader or the Mesh example.

Can you describe how you created the DFU image, and how you transferred it?

Are you sure that it is not running? The mesh examples doesn't necessarily use the LEDs, but I could see the RTT output that the example was running.

Best regards,

Edvin

I have encountered this problem before. The problem lies in the fact the mesh sdk assumes the mesh bootloader being present, and calls into it during initialisation, which is not supported by the BLE bootloader. The solution is to comment out the lines where this happens. in core/src/nrf_mesh.c there is a call to nrf_mesh_dfu_init(). (in nrf_mesh_init() , line 360) Comment that out, and then it should work fine with the BLE bootloader.
