Is it possible to deactivate Mesh DFU relaying from App side?

[rmarques]

We want to deactivate Mesh DFU packets relaying from the App side to avoid messing with the bootloader firmware. Is there any flag we may use for that?

Hi,

Yes, you can do this by ignoring the DFU relay requests, and never call nrf_mesh_dfu_relay. Note: that you can't control this in the bootloader.

To clarify: as long as the packet is forwarded to the bootloader, the bootloader relays it right? Nothing can be done to the packet to prevent this from happening? Changing a flag in the packet or something?

Yes, that is correct. There is a flagg in the packet but the bootloader ignores it.

Ok, thank you!
