My heart rate is not recorded when walking activity is done.

I went for a hikung. Since hiking is not  in the activiy list, I chose walking and it turned out the heart rate was not recorded. Wondering what is the cause of this issue

  • Was the HR sensor working (lighting) during the walk? If not, then you'll have to find out why - it could be for example because it was disabled globally, disabled by  the Power Mode selected in the activity profile, disabled by Battery Saver, sensor obscured (for example by a sleeve), hardware malfunction, etc.

    If you do not know whether it worked or not, try another walk and check whether the sensor is emitting any light.
