Brief Guide to Secure DFU via Gateway RESTful API

This document briefly describes the main process of performing DFU on BLE devices using the Nordic SDK through the BLE gateway's RESTful API.

Version	Update Notes	Update Date
v0.1.0	Basic Features	June 16, 2023
v0.1.1	Typo Fix	June 17, 2023
v0.1.2	Fix Set Receipt Notification Error	January 17, 2024

This document briefly describes the main process of performing DFU on BLE devices using the Nordic SDK through the BLE gateway's RESTful API.

The basic successful main process of DFU has been handled, and no additional processing has been done for the exception process for the time being

Specific use may need to be adjusted according to the actual situation of the device, please feedback in time if there are any problems.

4. Script Usage

The script is a NodeJS script. If Node is not installed, please install and use Node v10.0 or higher. For more details, refer to Nodejs

If the script is executed normally, it will complete the entire DFU process. If an error occurs midway, it will print error information.
