I’m the owner of a Tacx Vortex trainer. It is eqipped with a ANT+ Antenna (not a dongle). This one: Everything works fine with the TTS4, but in Zwift it won’t pair. It seems to find the ANT+ but not the rest. Any suggestions?

Me to. Do I need an alternative ANT+ dongle?

Have you updated your Vortex to the latest firmware ? Here is a link on howto do that


same problem here, I connect like powermeter 7719, but zwift dont control the resistance…

You must at least be at firmware 1.3.7 (update via iOS device only as I’m ware of)

How new is the Vortex. Make sure it’s the new T2180 “Smart” model, or you wont be able to connect.
