Oddly I find this when the sensor is off:
1. I call the widget heart rate and am asked if I want to turn on the sensor. If yes, all 6 diodes of the sensor light up.
2. also with the sensor turned off > I go to the "Sensors and Accessories" menu and turn on the sensor there. In this case, only the middle 2 diodes light up.
3. when I then call the widget heart rate, I logically see my frequency, but when I then press the start button, all 6 diodes light up again and do not switch back to 2 after exiting the widget.
Normal behavior ? (F7pro, Beta 14.26)
