I have been having trouble with my chest strap heart rate monitor

not record the projected respiration either. I sent it back to Garmin
for refund.

If you had the Coospro still within range of the watch, the watch may

Yes, that does seem strange. I'm not familiar with Coospro, but I know
the Garmin NRM models do store data until the activity is stopped and
the data transfer is complete. That may be the Coospro architecture as well.

AI suggested the garmin on the handle bars could be sensing vibration
and picking that up for a reading but once I shut the phone off no HR.
RIght now sitting here says my HR is 46 and I counted and it is close I

I don't know about the strap picking up the heart rate signal. I
replaced the straps on both my Garmin watches with Hemsut velcro
straps. My Fenix 5X is 7+ years old and it's heart rate measurements
are always very close to my finger clamp device and my Blood Pressure >moniter. The Fenix is the watch I almost always use for my bike ride
