Hi there, Is it only me that feels harder when I do workouts via BT? The same workout feels harder when I use my iPad and BT, while it feels so smooth when I do it on my PC via ANT+. Maybe I am just dreaming :slight_smile:

You’re probably dreaming. With both protocols, the trainer receives a target power, and then adjusts its resistance to maintain that power (assuming you’re in erg mode and not using Power Match). It’s the same trainer reacting to the same command - it has no way of acting differently.

Since I got me a Kickr I’ve always used Ant+, that is until just recently when I switched to BT. The main thing I noticed is that BT offers a more responsive feel and a smoother ride. I can’t determine if it easier or not but it feels different.

I might try tomorrow’s workout using BLE.

Will be interesting to see @gpl ’s result. I will also test this week BT and ANT+ over both desktop and mobile apps. I don’t have anything to compare but only RPE based result.

A trainer will be slower to react to commands over ANT+ than Bluetooth Low Energy (BLE), just because of how the protocols work. From what I remember of ANT+ FE-C communication: The trainer is master. Zwift/TR is slave Master transmits every 1/4 second (every 250ms) Slave is only allowed to trans…

Is there any advantage between protocols based on stability of connection?

TR recommends BLE for that reason.

I’m very interested to know if other users report this. I’ve not heard of it before. I’m curious to know the reasons. Maybe @gpl has some insights?
