long press the middle left button on your Forerunner (UP) select: wrist heart Rate -> Broadcast heart rate -> start. This works for both bluetooth and ANT. And yeah, using the watch without your phone for strava is pointless, if you want to ride routes with navigation or even just see your pulse in front of you ;) Turning On Pulse Oximeter Sleep Tracking. You can set your device to continuously measure your blood oxygen saturation while you sleep. NOTE: Unusual sleep positions can cause abnormally low sleep-time SpO2 readings. From the pulse oximeter widget, hold UP. Select Sleep Pulse Ox > On. New design: The Forerunner 55 resembles the Forerunner 245. It’s not a 1:1 match, but the similarities are abundant. Notably, the Forerunner 55 does not report heart rate data as often as So i just got a forerunner 35 2 days ago and its been a really good experienceapart from the heart rate. There is no way i have been averaging 175+bpm on my easy runs as I have been running in a group whilst talking to people during the run, do I just have a faulty unit or is my heart really working that hard? Press and hold down the power button for up to 5 seconds or until the watch turns off. Release the button. Again, press and hold down the power button for another 5 seconds for the watch to turn on. Go back to the Garmin Connect app and repair the watch. Check if the watch is measuring the heart rate. I bought my 245 music specifically for pool swimming and started running because of owning it. Since the 245/M doesn't record my heart rate whilst swimming it says I'm detraining even though I train 2-3 times a week. When I finish my swimming activity, the heart rate sensor working fine while I'm swimming casually. You can "pair" (make the device listen) the heart rate strap with both the watch and the Edge, and they'll both listen. You can tell if they're using the external sensor by looking for the heart icon. On the Edge it's in the drop-down at the top, and on the 245 it'll show up where the GPS signal level is at the top when you open an activity Had the same issue on my Forerunner 245. My watch gets GPS fine and tells me an accurate speed/pace, but the distance stays at 0.00 the whole time and it gets stuck on the Saving or Discarding screens. Plugged the watch in and it turns out there is only 1.35 MB of space left. .
