This is not a question, but I wanted to report that Heart Rate Broadcasting over Bluetooth (BLE?) is working to Apple TV HD. I know the question has come up a few times and the option was added on a recent Beta version, but I just wanted to report my findings.
I've been the Venu2 to broadcast over Ant+ to my Peloton Bike, but I wanted to use my Venu2 to broadcast to the Peloton app on Apple TV. When you go to the class details and click on the "heart" icon, you will be asked to accept Bluetooth connection.
