I'm trying to create a watch face which displays body battery. Even copying the code from the documented examples does not work. Any advice on what I'm doing wrong?
Watch: Forerunner 245, latest firmware update
App: Simple watch face
Minimum API supported: 3.3
Notes:
I've included "import Toybox.SensorHistory;" at the top of the code
Code runs until the following snippet is added / called
Code snippet:
// Create a method to get the SensorHistoryIterator object
function getIterator() {
// Check device for SensorHistory compatibility
if ((Toybox has :SensorHistory) and (Toybox.SensorHistory has :getBodyBatteryHistory)) {
// Set up the method with parameters
return Toybox.SensorHistory.getBodyBatteryHistory({});
}
return null;
}
// Used to draw body battery ring
// maths excessive for initilisation but function will be rarely called for that fuction
// low frequency call so memory saving better than power saving
private function bodyBattery (dc as Dc) as Number {
var bbIterator = getIterator(); // get the body battery iterator object
var sample = bbIterator.next(); // get the body battery data
if (sample != null) {
var currentValue = (sample.data / 10).toNumber() * 10; // we only want to display a granularity of 10%
}
}
