https://devzone.nordicsemi.com/f/nordic-q-a/53470/is-it-possible-to-deactivate-mesh-dfu-relaying-from-app-sideWe 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?en-USTelligent Community 13Wed, 23 Oct 2019 14:31:36 GMThttps://devzone.nordicsemi.com/thread/216418?ContentTypeID=1Wed, 23 Oct 2019 14:31:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:16ff0919-ddd0-4366-ad95-6e94a5afdf61rmarques<p>Ok, thank you!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/216406?ContentTypeID=1Wed, 23 Oct 2019 13:44:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:de280c0d-051a-48c3-8d8b-a3ac076197ecMttrinh[quote user="rmarques"]as long as the packet is forwarded to the bootloader, the bootloader relays it right?

Note: that you can&#39;t control this in the bootloader.</p><div style="clear:both;"></div>
