External HR: Polar Verity Sense.
I have had this Polar Verity Sense for over a year now, it's brilliant, always reliable, and doesn't get annoying to wear (I found an HR strap annoying at times).
When I connected the Verity for the first time (over a year ago), I never considered whether I should connect it using Bluetooth or ANT.
I noticed it was always connected via Bluetooth and never had problems.
Today I switched it to ANT (or ANT+ I'm not sure actually if the '+' was there), and noticed after half an hour it started to lag out quite a bit, how can this be happening?
I paused the run, deleted the sensor, and reconnected it with Bluetooth. No issues afterward.
I did nothing different than all the other times it worked fine.
Why would this be happening?
