Frequently asked
The adapter will not connect
- The adapter must be paired in the system Bluetooth settings (Settings → Bluetooth) first.
- The ignition must be on — the adapter is powered from the OBD-II port.
- Make sure no other app (Torque, Car Scanner, etc.) is holding the adapter.
- Connecting can take up to 90 seconds: the app walks through several methods to wake a sleeping adapter.
Connected but no data
- Check that the background service is running (the indicator in Settings).
- Check internet access: data goes to https://device.llcar.ru.
- If you use a filtering VPN, add llcar.ru to its exclusions or enable the VPN bypass in Settings → Server.
Why does the app ask for permissions
- Bluetooth — communication with the adapter; diagnostics are impossible without it.
- Microphone — sound analysis; off by default, enabled in Settings.
- Location — route tracking; off by default. Precise coordinates are not transmitted, only an approximate geohash is sent.
How do I delete my data
Write to llcar@llcar.ru and include the client identifier from the app's Settings.

The AI assistant does not answer
The model runs on the device and is downloaded separately (about 1.4 GB, Wi-Fi
recommended). The app works without it: the knowledge base, the situation matcher and all
sensor readings remain available.
Compatibility
- iPhone with iOS 15.0 or later.
- A Bluetooth OBD-II adapter (ELM327 or compatible).
- A vehicle with an OBD-II port (petrol, diesel, hybrid, electric).
