About this app

Use this app to identify the real ELM327 version you have, because a lot of China clone adapters often declare a wrong ELM327 compatibility.

ELM327 Identifier sends almost all AT commands available and shows what are supported in accordance with the ELM327 official datasheet (up to firmware v2.2 and v2.3 experimental), so you can quickly check if the adapter declaration is correct or if it's a fake adapter.
Some AT command requires a car connection with specific protocol to work; to obtain comparable results, these commands aren't checked by the app. The number of AT commands checked are 114.

1 - power on the ELM327 adapter (by the car diagnostic interface or simply by a power supply)
2 - if not already done, pair the ELM327 adapter from the android device bluetooth settings or connect ELM327 wifi with the android device
3 - start the app and press CONNECT button, select the connection type and eventually select the paired ELM327 adapter
4 - after the correct connection, the scan automatically starts
5 - wait for the end of the scan and check the results on screen, a white bar shows you what commands (above) should be supported
6 - press RESULTS to show scanning details and optionally save results into the internal SD card.
7 - optionally press RESCAN button if you want to verify again the adapter

IMPORTANT: a fake adapter doesn't mean that it will not work with your applications.

I never wrote a comment on this before. I can say the tool is useful to compare adapters and it sticks to real version numbers from Elm. The last update from January 2024 made the vlinker mc+ up to 2.3 as the iCar also.

My appreciation to the developers of this app. It works with Veepeak BLE+. However, It would be better if it can connect to broader OBD scanner such as AUTOPPHIX 3210. The scanner can not be paired within the Android BT settings but still be connectable with couples of apps.
