Pairing can sometimes take up-to 25 seconds and sometimes you have to try it several times.

3: ElmAllObd asks the supported protocols.

Sometimes a "hidden" Elm327 v1.0
On the Tested Elm327 page there are two tested Elm interfaces.

You can only really test this Elm327 by checking whether a Ecu can actually be read.
You can try this with one of the many brand-specific apps that are available.
If you cannot find a brand-specific app for your car brand, or if it does not exist, then you have one other option.
Then you can try to test your Elm327 interface by using my server.
You may choose one of the Ecu's I have tested that you would like to use for the test.
