The URL it gave me = https://jpdiag.akress.com/jpdiag.php?Li ... D=9A3EFF5D

yes it didn't collect many data .
have you tried with an other elm ?

Hello, I have exactly the same problem with my 2018 Ducati Panigale V4.
I'm using an ELM 327 V2.1 with Bluetooth (China). I tried changing the communication speed to 9600 baud, but it didn't work any better.
Is it a ELM 327 problem or cable problem !!??

if you can see the elm version , don't touch the speed ; it's the correct one

it's possible your elm is not fully compliant yes . prefer 1.4 version

Same problem. Has anyone managed to solve it?

if the problem is the elm unit, can anyone tell me which one to buy? this is already the second one I've changed and it doesn't work

Hello
After experiencing the same problem with my ELM327 Bluetooth V2.1 as thesanerone. I ordered an ELM327 USB V1.4 and it works for my Panigale V4 2018 .
The problem comes from the ELM version .
Version 2.1 is not supported by the MelcoDiag application.

thanks for the feed back.

it's not as simple as a matter of version.
some cheap elm only works on 7df pid , this is a broadcast PID that can be used with standard electronics systems .
but our bikes are more picky , they need specific PID's
