Heart rate sensor stops periodically. stevefox over 4 years ago. A few days ago my VA3 heart rate sensor began randomly stopping. I will notice my heart rate is "0" on the display. The LED's will not be flashing. If I turn the watch off and on, the measurement will restart. I've noticed that if I just leave it, it restarts on its own after a while. I have used it with success on my vivoactive 3. You must pair the chest strap as ChrisSinfield1963 mentioned.

You can view heart rate data on the heart rate widget. If both wrist-based heart rate and chest heart rate data are available, your device uses the chest heart rate data. Wrist-based Heart Rate. SAME HERE! VA3-Music. I have this problem multiple times per week. I shut it off, wait, and turn back on and SOMETIMES it works. If not, then I do a reset (HUGE PITA because I have to reconnect to phone, reconnect to wi-fi, reconfigure watch face and I lose my progress). .
