Hello,
it appears that there is no smart trainer functionality when I pair TPVr to an Elite Drivo. It connects, but only works as dumb trainer.
For the record:
I just checked and the trainer is updated to the latest Drivo/Drivo2 firmware.
I have checked the "trainer compatibility" box in the settings
The Drivo has all the smart functionality (simulating climbs/ wind/ Erg mode etc) when paired to an app other than TPVr.
