The fix is to use &quot;--family NRF52810&quot;. Note that this is only supported in recent nrfutil versions, so you should update to the latest (currently&nbsp;3.5.1).</p> <p>For the specific questions:</p> <p>1. Yes, the application and bootloader version is user-defined. (The&nbsp;limitation&nbsp;is that you can only update to a higher version that the current version.)</p> <p>2. Yes, there is only version &quot;1&quot; (for now).</p> <p>3. The&nbsp;NRF_DFU_SETTINGS_VERSION&nbsp;preprocessor definition is not set in a .c or .h file, but rather in the Makefile or project settings.</p><div style="clear:both;"></div>
