Hello, I am 955 solar user.
I recently got a replacement due to heart rate error of 955 solar.
But it has same problem, too. So I don't think it's a H/W problem.
My issue is a heart rate is inaccuracy when I'm not using acitivity mode(riding, running and other activity) of 955 solar.
I did zwift using tickerfit+edge830.
At this time, the heart rate of the ticker fit is about 160
But, the HR of 955 solar is about 90~100 (at this time, 955 is not working in acitvity mode)
If I run the acitivity mode(anything) of 955 solar, then the HR of 955 solar quickly goes up to 160(same to ticker fit)
I wonder if this is normal.
