Speed lag ANT+ antenna / classic trainer


(Jedrzej LENARCIK) #1

Hi,

I have some issue with speed during my rides. I have Tacx i-Vortex (T2170) which is not compatible with Zwift… but also have Garmin ANT+ Speed Sensor and ANT+ antenna included with my Tacx trainer. Everything is OK, zwift is recognizing speed sensor but frequency of speed sampling is very pure (lag is big). When I start pedaling it takes about 15-30 seconds that zwift see it. When I stop my virtual alter ego is slowing very long time. 

What is wrong?
