As you mentioned, you can bootload external memory from the app&nbsp;(from the App Store), which uses the library. It&#39;s exactly the same code, though the default parameters might be different. The apps have no knowledge or visibility of accessories or other functionality attached to nRF5340 during DFU.</p> <p>Kind Regards,</p> <p>Abhijith</p><div style="clear:both;"></div>
