I do not think an even more condensed guide would be useful, as you need a minimum level of knowledge in order to understand the bootloader and DFU process. You might also want to refer to the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.2.0/lib_bootloader_modules.html?cp=4_0_0_3_5">bootloader documentation</a> or <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.2.0/examples_bootloader.html?cp=4_0_0_4_3">DFU examples</a>, but that will give you more information in a less condensed way (which I guess is not what you are looking for).</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/150539?ContentTypeID=1Wed, 26 Sep 2018 16:20:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bb809ff9-eb54-4882-b7bf-66657c7e0dabRichard D.<p>While the procedure described appears (and is) laborious, all except Step E are one-time setup stuff. &nbsp;Step E is the procedure to actually update an application OTA.</p><div style="clear:both;"></div>
