SW 15.19 HR sensor blinks a few times each minute when watch is unworn

hassan987 over 2 years ago

Just a quirk I noticed since the update,

The sensor LEDs blink briefly every few seconds when the watch is not on your wrist.

This did not happen with 14.XX softwares on both my 955 and wife's 255S.

I'm not sure if this is a bug or not. If it is not a bug, what purpose could it serve?

To detect if it's worn or not?

As at least old versions gave HR from who knows what, so if that would do some detection if it's worn or not, so should it…

I can see the blinking at 15.19 as well. Very slight and short blink of the red LEDs. Never noticed that in the previous firmwares. Maybe someone still on 14.xx could confirm?

Both green and red blink for me, as seen in the video.

As at least old versions gave HR from who knows what, so if that would do some detection if it's worn or not, so should it try to find HR or not and report it or not?

But I kind of feel it pretty irrelevant if it blinks or not, do you have some real concern here?
