# Pix Backpack Go: reconstructing PIX display control over BLE

> Pix Backpack Go reconstructs local BLE control of PIX Backpack LED displays as a Go library and CLI. Its protocol notes and code cover GATT commands, RGB palettes, image and animation upload, live updates and scrolling text, drawing on app materials and local BLE experiments.

## Requirements & limits

- **Prerequisites:** Go 1.25 or later is required; macOS hardware use also needs Bluetooth permission and Xcode Command Line Tools.
- **Testing evidence:** The author reports testing on PIX Original V1 firmware 2.5.1 with a 16×20 display.
- **Limits:** Game controls, other firmware and Mini are experimental; flash persistence, OTA and PIN management remain unverified or unavailable.
- **License:** MIT license for the implementation and documentation; bundled PIX Mono fonts use SIL OFL 1.1.
