I'm experiencing heart rate wrong data during activity.

I'm experiencing heart rate wrong data during activity. I tested it with fenix 5x, 5x plus and 6x plus. It works fine for the very first 20/30 minutes then drop under 110 bpm and stays there until i restart the app. I tested with many app on store and also one i m developing. With my app i tried with a chest band and it works like a charm. Is there something with the whirst sensor??

thank you

OHR can have issues based on things like skin tone, tattoos, even how hairy you are, It's also got two modes - a less accurate 24/7 mode and an activity mode. You can tell which mode you in by peeking…

1. I've asked if you call getActivityInfo() only once (e.g. in initialise), but probably not because in onUpdate so you have current info

2.Activity.getActivityInfo() can return null....

var

a = Activity…

but he's not getting null In fact he even gets a "valid" currentHeartrate that is < 100

function getHRData_RT()

{

// populate global HR data object

HRInfoObj=Activity.getActivityInfo();

if (HRInfoObj!=null && HRInfoObj.currentHeartRate != null)

{

ActualHRVal=HRInfoObj.currentHeartRate;

} else {ActualHRVal=0;}

gentlemen... i'm trying to get rid of a problem that is not a memory leak or out of memory or not compiling: To me looks like a common (not only mine) issue which is affecting the HR sensor.

I'm trying to change the plot to see if something change and lightup the bug

So please run along the forum, check all the others having the same issue and try to understand if could be a fw issue or not.

as far as i know in app onupdate is not fired each sec as for watchface. You need to use a timer and so YES there is a timer firing the onupdate where i can update the display, retrieve sensor data, etc...
