Hacking Bluetooth to brew coffee in GitHub actions

This is my adventure reverse engineering a De'Longhi coffeemaker's Bluetooth-Low-Energy-based protocol, writing a rust CLI for it, and hooking it up to GitHub actions to let us brew from either the browser or the GitHub app by filing issues (all the coffee are defined in issue templates).

In plain words

This project reverse-engineered a De'Longhi coffeemaker's Bluetooth protocol and built a Rust command-line tool to control it. The maker integrated it with GitHub Actions, allowing users to trigger coffee brewing by filing issues in a repository through their browser or GitHub app. Issue templates define different coffee options. It's designed for developers interested in IoT automation and Bluetooth protocol exploration.
