ELM327 OBD2 Bluetooth Tool for Android Smartphone

Simple Bluetooth OBD2 Adapter for Android

This ELM327 Bluetooth adapter is a low-cost way to connect compatible Android phones or Windows computers to a vehicle’s diagnostic port for simple engine code reading and live data through a compatible app.

It is an app adapter, not a full diagnostic scan tool. It is mainly suited to basic engine fault code checks on OBD2-compliant vehicles.

Best Suited For

This adapter is best suited to Android users who want a simple, affordable tool for checking engine fault codes and viewing selected live engine data.

It can be useful as a glovebox tool for quick checks, but it is not designed for deeper manufacturer-level diagnostics.

Key Features

• Bluetooth OBD2 adapter for Android phones and Windows PCs
• Works with many compatible OBD2 apps
• Reads and clears engine fault codes where supported by the app
• Displays selected live engine data
• Compact plug-in design
• Low-cost option for basic checks

App-Based Operation

This adapter requires a compatible third-party app. App features, app cost, supported data and phone compatibility vary depending on the app used.

It is generally not suitable for iPhone or iPad users. iOS users usually need a WiFi or Bluetooth LE adapter, depending on the app.

Vehicle Compatibility

This adapter is intended for OBD2-compliant vehicles with a standard 16-pin diagnostic port. It is mainly for engine and emissions-related diagnostic data.

It will not provide full-system access to ABS, SRS airbags, transmission, service resets, battery registration, DPF functions or coding.

Is This the Right Scan Tool for You?

Choose this adapter if you want a cheap Android-based option for simple engine code reading.

If you want a more reliable Stahlcar-supported app adapter, compare this with the ST400. If you need full-system diagnostics, choose a handheld scan tool instead.
