Carrera HYBRID BLE Controller

Control Sturmkind Carrera HYBRID RC cars via BLE from any Linux machine with Bluetooth.

Requirements

• Python 3.10+, bleak (BLE), bless (MITM proxy)
• Linux with BlueZ and a BLE-capable adapter
• Install: pip install bleak bless

Protocol

20-byte packets sent every ~50ms via Nordic UART TX (6e400002-b5a3-f393-e0a9-e50e24dcca9e):

BF 0F 00 08 28 00 [GAS] [STEER] 86 00 72 00 02 FF [LIGHT] 00 00 00 00 [CRC8]

Scripts

scripts/carrera_drive.py — Drive Controller

# Basic commands
python3 scripts/carrera_drive.py forward [gas] [duration_ms]
python3 scripts/carrera_drive.py back [gas] [duration_ms]
python3 scripts/carrera_drive.py left [gas] [duration_ms]
python3 scripts/carrera_drive.py right [gas] [duration_ms]
python3 scripts/carrera_drive.py spin [gas] [duration_ms]
python3 scripts/carrera_drive.py light_on
python3 scripts/carrera_drive.py light_off
python3 scripts/carrera_drive.py demo

• gas: 1-50 (default 40)
• duration_ms: milliseconds (default 3000)
• Edit ADDRESS in script to match your car's BLE address

On callback car_forward, car_back, etc. → run the corresponding carrera_drive.py command.

Calibration

At Gas=20, Steer=80: one full circle ≈ 7100ms. Adjust timing for your surface/car.
