Kickr Core resistance issue

Anyone else found something similar?

TL;DR: you might consider rolling back the firmware.

Hey there to all: Hope everyone is well and keeping safe. Listen - I think something is up with my trainer and I want to see if people can help me trouble shoot and maybe figure out what is up. I use a BMC bike on a Wahoo Kickr core with Apple TV. Since doing my last spin down calibration with t…

Thank you for the info. I tried some of this.

It turned out to be a faulty ANT+ dongle. It must have been receiving power data but not sending the FE-C data. Fixed with a new one.
