About this app

A key feature of the nRF5x Series and their associated software architecture and S-Series SoftDevices is the possibility for Over-The-Air Device Firmware Upgrade (OTA-DFU) over Bluetooth LE. The DFU application allows to update nRF5 devices using Secure or Legacy DFU bootloader from nRF5 SDK version 4. 3 or newer. The nRF5x Series chips are flash-based SoCs, and as such they represent the most flexible solution available. The firmware should be in . zip file format, prepared using "nrf util" ( ).
