https://devzone.nordicsemi.com/f/nordic-q-a/55736/dfu-ota-using-a-pc-appWe&#39;re developing a product where a single NRF52840 board - lets call it the central- serves as the focal point for multiple NRF52840 boards spread out across an area - lets call these boards peripherals. So, we have one central connected to a PC via USBen-USTelligent Community 13Wed, 18 Dec 2019 09:30:04 GMThttps://devzone.nordicsemi.com/thread/226061?ContentTypeID=1Wed, 18 Dec 2019 09:30:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:516fad69-57da-4d08-881b-ad2db55e0badEinar Thorsrud<p>Hi,</p> <p>We do not provide a C# DFU master implementation for the PC side. However, we provide two options which you can use or refer to (both require an nRF board connected to the PC):</p> <p>1) Use <a href="https://github.com/NordicSemiconductor/pc-nrfutil">nrfutil</a> from the command line, and integrate that with your application.</p> <p>2) Pick what you can reuse from nRF Connect for desktop. The <a href="https://github.com/NordicSemiconductor/pc-nrfutil">core is found here</a>, and the <a href="https://github.com/NordicSemiconductor/pc-nrfconnect-ble">BLE app</a> supports DFU, using the <a href="https://github.com/NordicSemiconductor/pc-nrfconnect-launcher">nRF DFU library</a>.</p><div style="clear:both;"></div>
