nRF Device Firmware Update: Update Your Firmware with Ease

nRF Device Firmware Update is a mobile app that allows you to update the firmware of your nRF51 or nRF52 Series SoCs using Bluetooth Low Energy as a transport. It is developed by Nordic Semiconductor ASA and is available for free on the Android platform under the Utilities & Tools category.

This app supports the updating of firmware that is in .zip file format, prepared using nRF Util. The firmware can be selected from the local storage on your Android device or downloaded from the cloud using a deep-link. However, it is essential to note that this app cannot be used to update firmware developed with the nRF Connect SDK. In that case, the nRF Connect Device Manager mobile app must be used instead.
