Currently using kickr pro paired with iPhone, also have wahoo app paired with fans etc. Erg mode works wonderfully, but when I toggle it off to standard mode nothing changes. This happens on multiple trainers. I tried closing the wahoo app to ensure that connection was not controlling. Any ideas? PS - I was able to get it into standard mode by unplugging all and reconnecting the trainer starting on standard mode. However, as soon as I went to erg it was stuck again. Also - this issue does not happen with zwift. TIA.
This is a bit strange.
Just to confirm, you’ve tried reproducing this with the same setup in Zwift and haven’t had any issues. Is that right?
A couple of questions for you:
- Were you using BLE or ANT+ to connect to TR?
- Was the Wahoo app fully force-closed (not just backgrounded) before trying to switch modes?
- Does the issue happen without the Wahoo app ever being open in that session?
It sounds like Wahoo’s app can hold a BLE control lock on the trainer, which prevents TR from switching resistance modes even after closing the app (the BLE connection sometimes persists in the background).
Let me know what you find..
Doesn’t iPhone default to Bluetooth for TR connection? Can I choose this in TR?
I can test if this happens when wahoo app is never opened. Holding that connection would make sense. It happens on multiple trainers in different localities, but always same cell phone.
Yeah, Bluetooth is the only natively supported signal. Sorry for any confusion there. 
I’d check to see how things behave without the Wahoo app on.
