Tacx Vortex resistance issues


I am using a Tacx Vortex and the resistance is not altering.
I have updated the firmware, and calibrated the trainer.

I have paired the trainer.
Yet when I get to a hill, the resistance does not change.
I have tried this on 2 computers with 2 different ant+ dongles.

I have connected the trainer to Bcool and the resistance changed instantly.

try disconnecting your Vortex in the Tacx app before using it in Zwift. It is a known issue. 

Done that…  Switched Bluetooth off as well.



Hi Mark,

Make sure trainer difficulty is set to beyond zero and that it is paired as both a Power Source and a Controllable Trainer.

Difficulty needs putting to 100% in settings

It was the ant+ stick. Bought a new one, seems to have been solved.
