Alternatively you can have a look at the legacy DFU solution from SDK 11, which had a solution where you can also initiate the DFU process over the air (&quot;buttonless DFU&quot;). We also have a buttonless DFU solution for secure DFU, in SDK version 13 and newer, but those SDK releases only supports the nRF52 series.</p><div style="clear:both;"></div>
