https://devzone.nordicsemi.com/f/nordic-q-a/79242/nrf52840-dfu-otaGreetings, I am looking over your React Native Git Repo &quot; This library allows you to do a Device Firmware Update (DFU) of your nrf51 or nrf52 chip from Nordic Semiconductor. It works for both iOS and Android.&quot; We are using the &quot;nRF52840&quot; chip in our boarden-USTelligent Community 13Fri, 03 Sep 2021 13:23:52 GMThttps://devzone.nordicsemi.com/thread/327989?ContentTypeID=1Fri, 03 Sep 2021 13:23:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e720734d-1832-4df9-aec6-af9326283430ovrebekk<p>Hi Jonathan</p> <p>I assume you are referring to this?<br /><a href="https://github.com/Pilloxa/react-native-nordic-dfu">https://github.com/Pilloxa/react-native-nordic-dfu</a></p> <p>This is not a repository provided by us, so it is limited what support we can provide, but in general I would expect their DFU solution to work with any device in the nRF52 family.&nbsp;</p> <p>The DFU implementation doesn&#39;t really care which nRF52 device you use, as long as the size of the images is scaled accordingly.&nbsp;</p> <p>Best regards<br />Torbjørn</p> <p></p><div style="clear:both;"></div>
