LELink Bluetooth LE OBD-II Car Diagnostic Adapter — Configurable Auto On/Off, iPhone & Android Live Data

This compact, low-energy OBD2 dongle turns a smartphone or tablet into a real-time vehicle scanner without complex setup. It supports all OBD-II/EOBD compliant cars worldwide, works with a wide range of popular apps, and includes new user-configurable features like auto on/off zero-power standby and passcode protection so the device stays secure and power-efficient when not in use.

How does the LELink adapter connect to my phone or tablet?

The adapter uses Bluetooth Low Energy (BLE) to link directly with compatible apps—no traditional Bluetooth pairing required for LE-capable devices. Simply plug the device into the vehicle’s OBD-II port, open a supported app on your phone or tablet, and choose the LELink unit from the app’s connection options.

• BLE connection means fast reconnection and minimal battery drain on the adapter.
• Compatible with iOS (iPhone/iPad/iPod) and Android devices.
• Works with both free and premium OBD apps like Torque, OBD Fusion, and LeafSpy Pro.
• No extra cables or pairing screens for LE-enabled devices—plug and go.

What diagnostics and real-time data can I read from my car?

LELink provides access to standard OBD-II parameters including stored and pending fault codes, live sensor values, and emission-related data. With a compatible app you can monitor engine RPM, coolant temperature, fuel trim, oxygen sensor readings, and more to understand vehicle behavior or troubleshoot issues.

• Read and clear generic and manufacturer-specific trouble codes.
• Stream real-time parameters like RPM, speed, and temperatures.
• Log data for later review or export for performance analysis.
• Use supported apps for advanced features such as graphing and custom dashboards.

Will this work with my car and which apps are supported?

LELink conforms to the universal OBD-II/EOBD standard, so it functions with any vehicle that adheres to that protocol—most cars sold globally since the late 1990s. The adapter also supports many well-known OBD apps, giving you flexibility to choose an interface that fits your needs from simple code readers to full telematics suites.

How do the new auto on/off and security features help me?

New configurable auto on/off lets you minimize the adapter’s power draw when the vehicle is parked, avoiding battery drain. Passcode protection restricts unauthorized access to the device, so only users with the code and a compatible app can retrieve vehicle data.

• Zero-power standby mode to prevent battery depletion when idle.
• User-set auto-power options to control when the adapter is active.
• Passcode protection adds a layer of privacy and security for your vehicle data.

Who is this for? LELink’s BLE OBD-II adapter is designed for car owners, DIY mechanics, fleet managers, and performance enthusiasts who want instant access to OBD data on smartphones or tablets. It’s especially useful for drivers with OBD-compliant vehicles who prefer a lightweight, cross-platform solution that keeps power usage low and adds optional security for shared or fleet vehicles.
