## Description

ELM327 Identifier is a powerful Chrome extension designed to help you quickly determine whether your ELM327 Bluetooth or WiFi adapter is genuine or a clone. Many China clone adapters falsely claim ELM327 compatibility, leading to unreliable diagnostics. This tool sends nearly all available AT commands (114 commands) based on official ELM327 datasheets (firmware v2.2 and experimental v2.3) to verify your adapter's authenticity.

Using the app is simple: connect and pair your ELM327 device with your Android device or computer, run the scan, and review detailed results showing supported commands. The extension helps you spot discrepancies in claimed features, ensuring you can trust your adapter for automotive diagnostics. Note that some commands require a live vehicle connection to work and aren’t tested by the app. Users can also save scan results for future reference. Additionally, the app supports multiple translations thanks to community contributions.
