This app has been updated by Apple to display the Apple Watch app icon. * Improved compatibility with (more or less) ELM327-compatible adapters. * Better performance: Now 30% less data traffic due to a more compact transfer syntax. * In some rare cases during setup the App claimed that a WiFi controller wasn't recognized, although it was already identified.

Stuck at “loading services” forever

Somehow it keeps scanning for tens of bluetooth devices around me, instead of allowing me to simple pick the obd one, and it keeps “scanning services” forever, I waited for longer than 20 minutes for nothing

Does not read trouble codes

Purchased the OBD2 app to scan trouble codes. I hooked it up to an Elm Wi-Fi adapter, got it connected, but does not seem to read any codes or do anything beyond identify the vehicle. No settings or instructions. I purchased it as I thought it could read and clear codes. It does less than free apps currently. Maybe I’m missing something.

Don’t waste your time & money!!

I downloaded the app, paid for the complete app and the only thing the app does is “identifying..” my OBD tool that is clearly shown when you try and connect! Closed the app 5 times and the same thing every time, identifying but never connecting!

FAQ

What does OBD2 Expert do?

OBD2 Expert is a comprehensive tool for vehicle diagnostics and monitoring. It allows you to connect an OBD2 adapter to your vehicle to view real-time sensor data, read and clear diagnostic trouble codes (DTCs), and analyze various diagnostic parameters like Mode 6.

What are the key features of OBD2 Expert?

Key features include revealing vehicle problems before visiting a garage, loading vehicle status files to test app functionality, sharing vehicle status data with others, acting as a BLE-OBD2-ScanTool for developers, and serving as a BTLE/WiFi Bridge to inspect OBD2 protocol communication.

Is OBD2 Expert free to use?

The app is free to download and offers the ability to load vehicle status files to try out its functionality without connecting to an adapter. However, full functionality, including connecting to an OBD2 adapter, may involve in-app purchases.

What kind of Bluetooth hardware does OBD2 Expert support?

OBD2 Expert supports Bluetooth 4.0 (BLE) adapters. It will not work with older Bluetooth 2.x or 3.x adapters due to hardware limitations. It's important to ensure your OBD2 adapter is Bluetooth 4.0 compatible.

How can developers use OBD2 Expert?

Developers can utilize OBD2 Expert as a BLE-OBD2-ScanTool, eliminating the need for expensive hardware simulators when developing OBD2-related applications. Additionally, it can function as a BTLE/WiFi Bridge, allowing inspection of OBD2 protocol communication for learning or debugging purposes.
