Anyway, for those who don’t know, ANT+ is just basically a wireless protocol not that dissimilar to Bluetooth but it’s primarily used to transmit training data – like heart rate, cadence, and power. There are advantages in that unlike Bluetooth, ANT+ devices can connect to multiple devices simultaneously whereas Bluetooth is more of a dedicated 1 on 1 connection.
So, I can’t believe I didn’t realize all this time I was using Bluetooth LE to connect to my HR monitor, and not ANT+.
Just posting here in case someone knows something that I totally missed. Still puzzling how this phone doesn’t have that support whereas all the others Notes and Galaxy (post 2013) by Samsung do.
