Heart rate not rising above 120 bpm

Hi all,

On software 14.13, my heart rate (bpm) on Forerunner 255 doesn't rise above 120 bpm - it gets stuck. When doing an anaerobic effort, the heart rate doesn't respond and flat-lines.

See pics attached.

The Forerunner is only 3 days old, basically brand new.

Thanks

Which activity type are you using? The algorithm for measuring is very different between the activity types.

Broadcast HR over Bluetooth. The data recording is set at 1 sec.

But you are not running an activity? Then the heart rate readings will basically not work.

Are you saying you have to start an activity that is broadcasting HR, not using the standalone broadcast HR function?

I don't have experience in broadcasting HR, but if you don't start an activity, the algorithms for measuring wrist based HR will not be adapted to what you are doing. It will think you are just doing everyday things like watching TV or making dinner.
