Description
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.
HOW TO USE THE APP 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.

Really useful tool when you're going to buy a cheap LM327 replica, and be sure that you have bought a compatible device. Credits to the author!

Very easy to use and accurate detection of OBD device. Quick connection and report. Does what's advertised.

Fairly reliable then previously. Tested 5 Bluetooth devices read correctly, however Wi-Fi it got two correct and 4 known and working brands came back as unconnected, another app proved all to be ok. will look at this app in a few weeks and will update my results. But hey they trie, and it's a good free app for testing, just unreliable

One star because my device is not recognized or can communicate with app. My ELM327 is ENGIE branded in Android version. Is fault of my device or app isn't support yet?
