heart rate function dose not work on older watches if forerunner235 or hr 3

heart rate function :Activity.getActivityInfo().currentHeartRate

se not work on older watches if forerunner235 or hr 3

what should i do?

Are you running an activity that uses the HR sensor? I'm not sure if that value gets updated outside an activity on the CIQ 1 devices.

What are you using the HR for? What type of app?

watch face

How long since an activity was recorded? The data can go state after a while, and on older devices (CIQ 1) may not be updated in real time.

You may be able to fall back to

ActivityMonitor.getHeartrateHistory() and use the newest sample (a few minutes old any times), but I'm not sure.

Then there is no way to get it in a WF on those devices. Per the API doc, it's been available since 1.2.1

Get the heart rate history for the given period, up to the last power cycle.

This function always returns the most recent heart rate samples. The time between each HeartRateSample in the iterator may be device dependent.

Parameters:

period — (Toybox.Time.Duration, Toybox.Lang.Number) —
The period of time from which to retrieve heart rate samples
- If period is null, the entire available history is retrieved
- If period is a Duration, then the history for the given Duration is retrieved
- If period is a Number, then the last Number entries are retrieved
newestFirst — (Toybox.Lang.Boolean) —
The order in which to retrieve heart rate samples
- true to get the samples newest first
- false to get the samples oldest first

Returns:

Toybox.ActivityMonitor.HeartRateIterator —

An iterator for the heart rate history for the given period

Since:

1.2.1
