app connected but no data

[Jafar]

Hello hope that someone can help Me.
Have VW Touareg 7p 193kW Engine code CVVA.
After choose group code 10 I was able to connect to engine but no data. All is Green but all data field are empty. No idea what's wrong. BT Module or something else. On other place on this forum user reported no issue with application usage on the same car with the same engine code.
Any idea?

After the initialization connection, the app can start reading the parameters if you selected the related option, or enable the REFRESH button to let you update manually.
I see in your picture the REFRESH button disabled, this means that the app is stuck waiting for some confirmation from the ELM adapter that don't arrive.
It's difficult to me to know what's the problem, but this kind of error is 99% related to a low cost adapter that can't manage the canbus packets.
If you can, try with a good quality adapter.
