How to know if a device have optical heart rate available ?

Hello,

I developed a watchface for Forerunner 235 and 230 with heart rate information but there is a problem with Forerunner 230 without optical heart rate sensor.
I try to retrieve the HR history through ActivityMonitor.getHeartRateHistory() function but I suppose this function fail because watch face crashes...

How can I test that this function is available on the current device ?

I think I can use different ressources for each devices with a boolean to say if heart rate is available or not but maybe I can do differently...

Thank you.

Hi,

You could use this checking before your code:

if ( Toybox.ActivityMonitor has :HeartRateIterator )
{
//Your Code here
}
