Jpdiag

That's the problem. I haven't the license file.
When i click the blue button to get the license, and click the send button in the form, i got an error: the data is incomplete.

any chances for trying a different elm ?
i can generate a licence but i'mnot sure it can works , elm seems reading almost nothing

I have tried another elm, but is always an 1.5. Same story.
Writing "no ecu data" in the data collected for registration, the mail was sent and i received the license.
But the reset button for annual service is not working.
If you say that the app cannot read any data, i understand why the button doesn't work.
I'm searching an elm327 v 1.4, but is not so simple.
