ELM327 Identifier

ELM327 Identifier is an app used to check the version of the ELM327, as there are many China clone adapters that falsely claim compatibility. This app sends AT commands and displays the supported ones according to the ELM327 official datasheet. However, some commands require a car connection with a specific protocol, so they are not checked by the app. The app checks a total of 114 AT commands. To use the app, power on the ELM327 adapter, pair it with the Android device's Bluetooth settings, or connect it via WiFi. Then, press the connect button, select the connection type and the paired adapter, and start the scan. The results will be displayed on the screen, indicating which commands should be supported. You can also save the results if desired. It is important to note that a fake adapter may still work with your applications.

The ELM327 Identifier app has the following advantages:

- It helps users identify the real version of their ELM327 adapter, as many China clone adapters often declare a wrong compatibility.

- The app sends almost all available AT commands and shows which commands are supported according to the ELM327 official datasheet, allowing users to quickly check if the adapter declaration is correct or if it's a fake adapter.

- Some AT commands require a car connection with a specific protocol to work, so these commands are not checked by the app to ensure comparable results.

- The app checks a total of 114 AT commands.

- The app provides instructions on how to use it, including powering on the ELM327 adapter, pairing it with the Android device via Bluetooth or connecting it with the Android device via Wi-Fi, and starting the scan after the correct connection is established.

- The app displays the scan results on screen, with a white bar indicating which commands should be supported. Users can also press the "RESULTS" button to show scanning details and optionally save results into the internal SD card. Additionally, there is an option to press the "RESCAN" button to verify the adapter again if desired.
