I am using a Tacx Flux since a few week and since yesterday I am experiencing some power drop downs during a workout. For example: I should bike 3 minutes at 200 watt but it keeps going down to 150 for 1 second and then bounce up again.
My set up is a MacBook Air for the Zwift screen.
Garmin 530 to register my activity in Garmin connect
iPhone 11 Pro with bluetooth wireless earphones.
After the power fluctuations I tried different settings,
Once with my phone and without bluetooth earphones,
once with my phone and without the garmin
once with only my phone and same goes for using my MacBook instead of the phone.
I deleted the swift app on my phone and laptop. updated every device to the newest software and calibrated the Tacx multiple times. nothing really seemed to work.
After 2 hours by some miracle the original set up worked again but today I found the same problem.
Does anyone have an idea of what can cause this to happen?
