# alpha1s: reconstructing UBTECH Alpha 1S Bluetooth control

> alpha1s reconstructs the UBTECH Alpha 1S robot's Bluetooth control link as a Python SDK for telemetry, servo movement and stored actions. Its protocol layer documents FB BF frame headers, length and checksum fields, RFCOMM channel 6, a 16-servo command and optional BLE transport, with examples and tests against captured frames.

## Requirements & limits

- **Prerequisites:** A UBTECH Alpha 1S robot and compatible Bluetooth transport are required for hardware use.
- **Prerequisites:** The package specifies Python 3.9 or later; RFCOMM uses PyBluez on Linux, while BLE uses bleak.
- **Limits:** The API is being consolidated, and the author notes that some LED behavior still needs checking across firmware revisions.
- **License:** MIT license.
