https://devzone.nordicsemi.com/f/nordic-q-a/73024/ota-dfu-thread-merge-with-ncp-hexHi all, in my current platform I have: a DK (we are working to implement HW modifications to use a nrf52 dongle for this purpose) that is performing as a Thread DFU server (following this example https://infocenter.nordicsemi.com/index.jsp?topicen-USTelligent Community 13Mon, 22 Mar 2021 15:09:20 GMThttps://devzone.nordicsemi.com/thread/301258?ContentTypeID=1Mon, 22 Mar 2021 15:09:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d4ad969f-64df-4558-90e5-3201356212b4Edvin<p>Hello,</p> <p></p> <p>Actually, the NCP example is the one being used when running the command &quot;nrfutil dfu thread -f -pkg app_dfu_package.zip -p COMx --channel 11 --panid 43981 -r 4 -rs 5000 -a FF03::1&quot;. However, it is the uart version, and not the USB version.&nbsp;</p> <p></p> <p>Try manually compiling the dongle using nRF Connect for Desktop -&gt; Programmer, and then call your nrfutil call &quot;nrfutil dfu thread -pkg app_dfu_package.zip -p COMx --channel 11 --panid 43981 -r 4 -rs 5000 -a FF03::1&quot; without the &quot;-f&quot; flag. Does that work?</p> <p>Please note that the COM port may change after you program it with the NCP example.</p> <p></p> <p>Best regards,</p> <p>Edvin</p><div style="clear:both;"></div>
