https://devzone.nordicsemi.com/f/nordic-q-a/30485/source-code-of-the-sdk-51422-pca10028-s-firmware-availableHi, I wondered if the source code of the SDK 51422 PCA10028&#39;s firmware is available ? The one firmware which allows the SDK to flash other nRF51X over the air? If it is, where can I find it ? Thank you ! :)en-USTelligent Community 13Wed, 14 Feb 2018 14:43:29 GMThttps://devzone.nordicsemi.com/thread/120869?ContentTypeID=1Wed, 14 Feb 2018 14:43:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9b7991bb-e661-452f-9ffc-92ad7ad57aa8Edvin<p>Hello,</p> <p>I have not seen such an example for the nRF DKs, but you can do this in nRF Connect either for Desktop, or in the app for iOS or Android (or Windows).</p> <p>There is a good blog post <a href="https://devzone.nordicsemi.com/b/blog/posts/getting-started-with-nordics-secure-dfu-bootloader" rel="noopener noreferrer" target="_blank">here</a>, explaining how to use the OTA DFU (over the air device firmware update).</p><div style="clear:both;"></div>
