TR not seeing power from trainer since bike change w/ di2

Equipment
1

Hi there, recently changed my bike and it has the 12s Ultegra di2. Since then, my wahoo kicker core smart trainer has been not seeing the power and cadence whenever loading a workout or it’s very spotty. The device is connected via Bluetooth, and it’s paired and has been paired without any issues in the past.

I did all the testing of calibrations, removing the device, turning it off/on, etc and nothing is doing.

Has anyone ever encountered this issue ? Any thoughts as to what might be the issue ?

I even removed all potential interfering devices, etc but it’s not resolving the matter.

Thanks,
Jonathan

That sounds sketchy. I would try to debug:

  • Does it work without the bike mounted? That would be strange but who knows.
  • Did you change something else besides the bike?
  • To what kind of device are you trying to conmect?

Maybe the trainer got damaged somehow?

Agree it’s sketchy.

I put back my girlfriend’s bike on it (no di2) … no issues.

I added a Sonos speaker in the room, which I unplugged to test even if it was that. Removed all other connectivity elements on the bike, even my powermeter, nothing is doing.

Tested iPad instead of iPhone, no difference.

A bit out of solutions at this point. Would Ant+ or direct connect change anything ?

BT is sometimes finicky. If your bike was previously connect to your phone or another device via BT remove it and give it a shot. ANT+ I think is way better. Hope that helps.

No harm in trying it. A wild guess di2 is interfering with bluetooth but I thought that was more likely with Ant + :exploding_head:
