At Climbing or Downhill I have always the same resistence at my Trainer. How Can i fix it?
There is a good write-up on Zwiftblog regarding Zwift and the Tacx Vortex (see http://zwiftblog.com/vortex/ ) where issues are covered under the section “Help! My Vortex Smart isn’t changing resistance on hills!”
Most common issue is that you must disconnect bluetooth.
@Pawel: I had a look at your account, and you’ve only paired your Vortex under the Power category. You need to pair it under both Power and Controllable Trainer to get resistance.
@Jason K. thanks for your answer.
Is the pairing with bluetooth and the app on my android phone possible or only in the combination PC and ANT±Stick compatible ?
Both are possible. BLE instructions are here: https://support.zwift.com/hc/en-us/articles/206576683-Bluetooth-LE-BLE-Support-in-Zwift
