GR551x Fast DFU Example Application
This document introduces how to quickly implement Fast DFU on GR551x SoCs with the debugging App GRToolbox(Android) by using Bluetooth Low Energy (Bluetooth LE) technology, to help users have better understanding of FastDFU for GR551x SoCs.
● Introduction:
■ The Fast Device Firmware Update (Fast DFU) enables downloading the target firmware to a target device and enablesthe device to automatically check and update the firmware through Bluetooth transmission.
■ Compared with the over-the-air (OTA) technology which also enables downloading and updating the target firmware through Bluetooth transmission, GR551x Fast DFU greatly shortens the time for firmware update by providing Fast OTA Service which enables control, interaction, and various features of Fast DFU, as well as optimizing data read and write. As a solution for wireless firmware update, Fast DFU features faster update process and better user experience.
■ This document elaborates on principles and applications of Fast DFU for GR551x SoCs.
