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 |

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

Protocol Details
See references/protocol.md for full reverse-engineering notes and MITM capture analysis.
Usage Guidance
This package appears to do what it claims: control and reverse-engineer Carrera HYBRID cars via BLE. Before installing: (1) Review and run in a Python virtualenv and inspect the bless package source if you plan to use the MITM features. (2) Edit the ADDRESS in scripts/carrera_drive.py or use the provided scanner snippet to find your car. (3) Be aware the MITM instructions describe intercepting an app-to-car connection — do not perform that on devices you do not own or have explicit permission to analyze. (4) No external network endpoints or secrets are requested by the skill, but any code you run has access to your local system and Bluetooth adapter, so run only on a trusted machine.
Capability Analysis
Type: OpenClaw Skill
Name: carrera-hybrid
Version: 1.0.0
The skill bundle provides legitimate tools and documentation for controlling Carrera HYBRID RC cars via Bluetooth Low Energy (BLE). It includes a Python script (scripts/carrera_drive.py) for sending control packets and detailed protocol documentation (references/protocol.md) derived from reverse-engineering. No evidence of data exfiltration, malicious execution, or harmful prompt injection was found.
Capability Assessment
Purpose & Capability
Name/description match the included files: protocol documentation and a BLE drive script. Required libraries (bleak, bless) and Linux/BlueZ are appropriate for BLE control and MITM capture. Minor note: the SKILL.md claims 'Telegram remote control' support but doesn't include a ready Telegram bot implementation — it only suggests mapping callbacks to run the script.
Instruction Scope
Instructions stay within the stated purpose (driving, reverse-engineering via BLE). They include a MITM proxy method using 'bless' (explicitly describing how to create a fake peripheral and log writes) and a small Bleak-based scanner snippet; both are relevant to reverse-engineering but the MITM guidance can be used to intercept another person's device — it's within scope but ethically/legal considerations apply. The skill does not read unrelated system files or request extra environment variables.
Install Mechanism
No install spec (instruction-only) and the README asks to pip install bleak and bless. This is proportionate: bleak is the standard Python BLE client; bless is referenced for MITM capture. No downloads from untrusted URLs or archives are included.
Credentials
The skill declares no environment variables, no credentials, and no config paths. The code uses a hard-coded ADDRESS placeholder that the user must edit or replace with a scanner-run value.
Persistence & Privilege
always is false and the skill does not request persistent system privileges or modify other skills/configs. The skill is user-invocable only and does not ask to run autonomously with elevated presence.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install carrera-hybrid - After installation, invoke the skill by name or use
/carrera-hybrid - Provide required inputs per the skill's parameter spec and get structured output
