LELink Bluetooth Low Energy OBD-II Car Diagnostic Adapter — Configurable Auto On/Off, Passcode Protection

This compact OBD2 adapter uses Bluetooth Low Energy (BLE) to deliver live engine data, read and clear diagnostic trouble codes, and support a wide range of third-party apps. Plug it into any OBD-II or EOBD compliant vehicle worldwide and access sensors, performance metrics, and fault codes through popular apps like Torque, Car Scanner, Engine Link, and the free Engine Link LE. The device adds a new configurable auto on/off zero-power standby and optional passcode protection so it won’t drain the car battery or allow unauthorized connections.

How does the LELink adapter help me diagnose my car?

The LELink acts as a bridge between your vehicle’s OBD-II port and diagnostic apps on your smart device, showing sensor values, error codes, and engine performance in real time. You can pull stored or pending fault codes and view live PID data to narrow down issues before visiting a repair shop.

• Read and clear generic and manufacturer OBD-II trouble codes (DTCs)
• Stream live sensor data: RPM, coolant temp, fuel trims, oxygen sensors
• Monitor performance gauges and log data for later analysis

Which phones and apps work with this Bluetooth adapter?

LELink is built for cross-platform compatibility: it communicates with both iOS and Android devices that support Bluetooth Low Energy. It works natively with LELink’s apps and with industry-standard apps for deeper diagnostics or performance tuning.

• Compatible with iPhone, iPad, iPod and Android phones and tablets
• Supports Engine Link LE, LELink Scanner, LELink Security apps
• Also compatible with Torque, Car Scanner, OBD Fusion, LeafSpy Pro, and more

Will this adapter work in my car and what about power usage?

Any vehicle sold with an OBD-II or EOBD port should be compatible — that covers most cars and light trucks worldwide since the mid-1990s. LELink’s low-energy design minimizes current draw, and the new configurable auto on/off feature places the unit into a true zero-power standby when not in use.

• Works on all OBD-II and EOBD compliant vehicles worldwide
• User-configurable auto on/off prevents battery drain
• Plug-and-play operation with no manual Bluetooth pairing required for LE devices

Is my data secure and can others connect to the adapter?

LELink includes optional passcode protection to limit access to the adapter and your vehicle data. You can also control when the device is discoverable by using the auto on/off settings, giving you both convenience and privacy.

• Optional passcode locks the adapter to trusted users only
• Configurable discoverability reduces unauthorized connections
• Works with secure apps that respect device permissions

Who is this for: LELink’s BLE OBD-II adapter is ideal for DIY mechanics, vehicle owners who want insight into performance and fuel economy, fleet managers checking multiple cars, and enthusiasts who use third-party apps for data logging or tuning. It’s also a practical tool for technicians who need a compact, low-power diagnostic interface compatible with modern mobile devices.
