https://devzone.nordicsemi.com/f/nordic-q-a/36725/airfuel-sdk-uses-serial-dfuhi, nordic team: Now I am using the nRF5 AirFuel SDK version 2.2.0 to develop the PTU and successfully use the serial to do the dfu function. I used nrfutil for DFU, but I want to write a PC program instead of nrfutil. How can I do this?en-USTelligent Community 13Fri, 27 Jul 2018 08:14:35 GMThttps://devzone.nordicsemi.com/thread/141626?ContentTypeID=1Fri, 27 Jul 2018 08:14:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7e90bbbc-a94b-4446-911b-e276dfd1f853shuenn<p>Thank you,&nbsp;Bj&oslash;rn.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/141506?ContentTypeID=1Thu, 26 Jul 2018 11:46:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b026f0ee-9778-44d5-a59d-ca6ae1d638e3bjorn-spockeli<p>Hi Hung,</p> <p>the pc-nrfutil source code is available on Github (<a href="https://github.com/NordicSemiconductor/pc-nrfutil">https://github.com/NordicSemiconductor/pc-nrfutil</a>). I would recommend that you use this code as a reference for your own PC software.&nbsp;<br /><br /></p> <p>Best regards</p> <p>Bjørn&nbsp;</p> <p>&nbsp;</p><div style="clear:both;"></div>
