https://devzone.nordicsemi.com/f/nordic-q-a/17593/is-it-possible-to-do-live-dfu-over-the-radioI&#39;m wondering, is it possible? This is what I think it will be like if it were going to be implemented: Acquire the firmware from a host somewhere. Since the payload would have a max of 31 bytes, let&#39;s use only 16, for the sake of playing it safeen-USTelligent Community 13Fri, 11 Nov 2016 07:56:44 GMThttps://devzone.nordicsemi.com/thread/67639?ContentTypeID=1Fri, 11 Nov 2016 07:56:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:95f41cba-93cb-46bd-b4e8-923899e5d16eHung Bui<p>It&#39;s hard to understand what you&#39;re asking about, Mitch. Please describe it more clearly. What is your set-up? How do you want to do DFU, when in connection or when advertising.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/67638?ContentTypeID=1Fri, 11 Nov 2016 03:01:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4ab39687-1a4a-4433-92fb-f0fe55550508Mitch996<p>Hello, are you 2 suggesting a gatt connection between 2 devices to download firmware? My question still stands, what happens if the bond gets interrupted?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/67637?ContentTypeID=1Wed, 09 Nov 2016 12:58:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:babc08cb-94b1-4659-a9dc-6d363cde0cdeHung Bui<p>@Mitch: As Roger already mentioned, have you tried the DFU bootloader example ? If yes, why you want to do it with advertising packet?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/67636?ContentTypeID=1Wed, 09 Nov 2016 03:58:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:73b21795-0f5f-42c3-8a43-0421343bfaccRoger Clark<p>As you mention 31 bytes... Do you mean that something will be constantly broadcasting the firmware image as part of its advertising packet?</p> <p>Why not just accept connections and perform DFU in the normal way.</p><div style="clear:both;"></div>
