I maintain a project called [ITD](https://gitea.elara.ws/Elara6331/itd), a companion app for Pine64's [PineTime](https://www.pine64.org/pinetime/) smartwatch. The PineTime uses a Nordic nRF52832 SoC and implements the Nordic DFU protocol. I found the documentation for this protocol on Nordic's site to be severely lacking and had to resort to digging through source code to implement it properly. In this article, I'll explain exactly how to upgrade your firmware over BLE using the information that I've learned.

Once the firmware is successfully validated, write `[0x05]` to the control point, which tells your device to activate the new firmware and reset.
That's it! Your device should reboot running the new firmware. Some firmware (such as InfiniTime for the PineTime) requires you to manually validate the firmware in their settings or they'll revert on the next reboot, so make sure to remember to do that if your device requires it.
