Bad readings from an external HRM while RUNNING and JUMPING
I have a TT Music+Cardio and I'm using a Polar H10 HRM strap to measure my HR accurately during workouts, but I have noticed the TT gives me bad readings ONLY when I'm running (no matter the mode) or jumping - it basically stops measuring HR and shows some random number between 70 and 80. If I connect the HRM to an app on my phone, the readings are always ok, hence I know it has to do something with the TT.
I've tried turning all the surrounding BTs off, resetting the HRM, resyncing and nothing.
Anyone has a different idea?
