Haywatch

Haylou Smart Watch 2 (LS02) reverse-engineering project

Since nothing technical popped up about this watch model on the Internet (only the usual smart-watch articles and some apps), I decided to investigate and document it (its Bluetooth functionality) as deeply as I can.

This project contains the following:

• Documentation (work-in-progress) on reversed functionalities (here)

• Rust Bluetooth libraries implementing reversed functionalities (ls02 crate)

• Simple desktop Rust UI showcasing all this work and serving as an example for the libraries (haywatch project)

• Testing (dirty and quite unorganized) Rust command-line program, used to test/keep track of unknown watch requests/responses/etc, might also serve as an example for the libraries (ls02dev program)
