HRM sensor drops off

Just purchased Fenix 5 plus and since having it the Heart rate stops detecting on and off throughout the day and night. When I reboot it seems to be better for a few hours but gradually gets worse. During activities have not had drop outs. Seems very random as it can go all night without dropping out. Pretty sure I'm wearing it correctly as I've upgraded from Vivoactive 3 which had no problems. I believe it's a software problem but can't find anybody else having the same problems. Heart rate sensor is set to auto. Any suggestions would be appreciated...maybe a widget conflict?

It's a computer: reboot it every day.

Is that what you have to do?

You can find in this forum a BLE/ANT+/BL update that may fix your problem. Regards.

It won't hurt, and it might very well solve your issue.

Strangely enough I have recently been experiencing similar.

I have have my Fenix 5 plus and Garmin Basic HRM since launch. I was using this setup several times a week without issue, until winter set in

Just I have restarted my workouts and the HRM has started dropping out during my daily workout, I even replaced the battery and reset the HRM strap but the problem still exists. I had assumed either the HRM was starting to fail or maybe the fact my wife is now using a laptop in the room next to my home gym.

My watch is running ANT/BLE 4.30 and 11.00 firmware. I wonder if the upgrade to these versions are causing issues.

I have the same problem with my new 5s plus. Periodically it stops recording my HR. Once I go in the widget it startsa again My old Vivoactive 3 had this on some firmwares, but overall seemed a lot better regarding optical hr.
