Hi guys,
I´m new here and since yestarday I´m strugling with set up connection. I checked version on Tack, is up to date, app on windows pc up to date but I can´t calibrate or start propper run. Is says it is connected bo in the same time “no signal”. When I want toi ride sometimes will go for few seconds then stops again. What´s wrong? Any ideas?
did you try pairing with the ANT+ fe-c profile.
Do you have other software connecting to the trainer.
I have the same issue but with Kickr Core (seems like this is a long known issue if you search for “no-signal-in-the-pairing-screen” in the forum here).
it is really a pain 
If you’re using Windows 11 and Bluetooth, then it might be this problem - Bluetooth devices connect, but No Signal [January 2022] [Windows11]
I did pair with ANT+ profile. No othere software is connected to the trainer.
I have windows 10.
It look like you pair with bluetooth
When I switch off bluetooth and is only on ANT - basiclly same thing 
confirm your TACX app is not running at same time as it will conflict with zwift
it is not runnning in the same time
Try running the Tacx app by it self without zwift
