Been going crazy about this, if theres no solution Garmin should def take a look at this!
So my garmin edge logs RHR when I turn it on with my chest sensor or forerunner 965.
For example today when I woke up, my recorded RHR through the night was 46, I got out of bed, had breakfast and then turned on my edge 540 with my forerunner as a heart sensor while I was getting ready to go cycling, 2 min later the app on my phone showed RHR 54 because of the EDGE, of course is not resting cause im getting ready to go cycling!!
Same thing happens if im using my chest strap before cycling. I dont want my EDGE to log resting heart rate, im never resting when im using it!!
Anyone having this issue???
