What I Built

There is no clean, simple, cross‑platform, developer‑friendly BLE CLI today. Linux has bluetoothctl, macOS has no official CLI, and Windows exposes only low‑level PowerShell APIs.

Developers working with BLE devices — especially ESP32‑based prototypes — lack a simple, unified, ergonomic CLI. My goal was to create a minimal, script‑friendly CLI for scanning, connecting, and interacting with BLE devices.

My Experience with GitHub Copilot CLI

bt was built using Copilot, which acted as a co‑pilot for the project. It helped me in brainstorming, planning, and rapid prototyping using natural‑language processing—even when I made typos.

🤖 Copilot reduced context switching, provided pair‑programming assistance, helped with testing, and more.

As a beginner with Bluetooth modules, it guided me through documentation, debugging, beautifying output, and testing without leaving the IDE, polishing the whole project.
