Stress and Heart Rate in Low Power Mode

When you are in low power mode, onUpdate() is only called once a minute so nothing will change more often than that.  With the AMOLED devices, onPartialUpdate() isn't used.

Any idea why the Stress level displayed on my Watch Face does not always correspond to the one shown on the other watch face or on the Stress glance?

Native watch faces aren't written in Monkey C can can do this differently,

i am still able to access both Stress and Body data on my Venu 2

I'm puzzled then... doing as below using SDK 4.1 beta and Venu2system5preview (updated again today), but still getting blank values. If removing the "has :getBodyBatteryHistory" check, getting the "Could not find symbol 'getBodyBatteryHistory'" error.

if (ActivityMonitor has :getBodyBatteryHistory){
	var bbIterator = ActivityMonitor.getBodyBatteryHistory();
	var sample = bbIterator.next(); 

	if (sample != null){
		dc.setColor(Graphics.COLOR_WHITE, Graphics.COLOR_TRANSPARENT);
		dc.drawText(x, y, fontSize, sample.bodyBatteryData.bodyBattery, Graphics.TEXT_JUSTIFY_LEFT);
	}
}

Do CrusinUSA or anyone else have any clue of what I might be doing wrong? I assumed that if the simulator is not ready to simulate/show values for BB and stress, it should at least show zero and not throw an error about not finding the getBodyBatteryHistory class.

Here is the code i am using for Body Battery

Since i am blocked from showing Code, i will copy it below ...

               // Get Body Battery Data             

               function getBodyBatIterator() {

                   if ((Toybox has :SensorHistory) && (Toybox.SensorHistory has :getBodyBatteryHistory)) {

                       return Toybox.SensorHistory.getBodyBatteryHistory({});

                   }

                   return null;

               }

                   // Update the view

    function onUpdate(dc as Dc) as Void {

                                             // Show Body Battery

                                             sensorIter = getBodyBatIterator();

                                             dc.setColor(Gfx.COLOR_BLUE,Gfx.COLOR_BLACK);

                                             dc.drawText(358,55,myfontIQicons,"}",Gfx.TEXT_JUSTIFY_RIGHT);              

                                             if (sensorIter != null) {

                                                            dc.setColor(Gfx.COLOR_GREEN,Gfx.COLOR_BLACK);

                                                            dc.drawText(320,55,myfont48,Lang.format("$1$",[sensorIter.next().data.format("%02d")]),Gfx.TEXT_JUSTIFY_RIGHT);

                                             }

Thanks for sharing that CrusinUSA! However, still getting the symbol not found error on the simulator, even with a code that was adjusted to look very similar to yours... so I'll wait a bit more until the next beta (or final SDK version) is released to test BB and Stress.

One thing I noticed is that you're using SensorHistory instead of ActivityMonitor, the later being what I found on the API docs from beta SDK. Since you've mentioned the data not corresponding to the default Garmin widgets, then maybe you could give the ActivityMonitor a try to see if it improves the accuracy?

So far i have been unable to get Stress info using ActivityMonitor. I get a "Could not find symbol 'stress' error.

This is what Garmin wrote on the SDK 4.1 beta API docs:

using Toybox.ActivityMonitor;
using Toybox.System;

// get a StressHistoryIterator object
var stressIterator = ActivityMonitor.getStressHistory();
var sample = stressIterator.next();                        // get the stress data

while (sample != null) {
    System.println("Sample: " + sample.stressData);        // print the current sample
    sample = stressIterator.next();
}

You don't necessarily need the while and next should work just fine, but not working for me either way.
