This is a strange one. I have been using my Instinct Solar to broadcast HR to my 1040. Sometime between July 21st and August 3rd my Edge stopped recording HR. I finally remembered to look into it yesterday and found that the "sensor" was trying to connect via Bluetooth instead of Ant+. After deleting it and reconnecting as Ant+ it is working as expected again.
Anyone else have a sensor change protocols without any user input?
