The Concept
The standard LEGO Bluetooth protocols require complex asynchronous management to keep connections alive. TechnicMoveHub abstracts this complexity away.
By reverse-engineering the raw GATT characteristics, this library handles the asyncio event loop and BLE packet handshake internally. The result is a clean, synchronous API that lets you write linear Python scripts to control hardware without managing await chains or race conditions.
Key Features
- Sync-over-Async: Abstracts the
bleaklibrary to provide blocking calls for ease of use. - Motor Control: granular control over speed and direction for ports A, B, and C.
- RGB Management: Real-time LED color manipulation.
- Fault Tolerance: Includes graceful connection drops and exit handling if the Hub disconnects.
Installation
The package is available on PyPI:
pip install technicmovehub
