I am now using Buttonless DFU which works fine using nrfutil. But my question is : how can we update firmware code directly through our mobile or desktop application.

It seems Javascript code just supports USB CBC. Is there a clear workflow on taking client side for this process so we can implement it inside our application.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/187744?ContentTypeID=1Sun, 19 May 2019 12:55:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3a8e8aa0-dd3f-4157-9834-40f419acce2ckirkus<p>Nordic has a DFU library available for&nbsp;<a href="https://github.com/NordicSemiconductor/IOS-Pods-DFU-Library">iOS</a>,&nbsp;<a href="https://github.com/NordicSemiconductor/Android-DFU-Library">Android</a>, and&nbsp;<a href="https://github.com/NordicSemiconductor/pc-nrf-dfu-js">JavaScript</a></p><div style="clear:both;"></div>
