- description
- Control Carrera HYBRID RC cars (by Sturmkind) via BLE. Use when user wants to drive, steer, control lights, write text with, or reverse-engineer Carrera HYBRID / Sturmkind RC cars over Bluetooth Low Energy. Supports Telegram remote control with inline buttons, MITM proxy for protocol sniffing, and text-drawing via driving paths.
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]| Byte | Function | Values |
|---|---|---|
| 6 | Gas | 0xDF=idle, higher=forward (wraps 0xFF→0x00→0x11=max), lower=reverse |
| 7 | Steering | 0x00=center, 0x01-0x7F=right, 0x81-0xFF=left |
| 14 | Light | 0x82=on, 0x80=off |
| 19 | CRC-8 | Poly=0x31, Init=0xFF over bytes 0-18 |
