In a watchface I created which ConnectIQ (4.30) I can show the clocktime, but when I try to show the heartrate I get the error
Details: Module 'Toybox.Sensor' not available to 'Watch Face'
Stack: - onStart() at /Users/…/source/_garmin_projectAPP.mc:13 0x10000095 Permission Required
In the manifest I added all available permissions, I also imported the Sensor with
using Toybox.Sensor
I am also not sure where exactly to enable the heartrate-sensor with e.g.
Sensor.setEnabledSensors([Sensor.SENSOR_HEARTRATE]);
Sensor.enableSensorEvents(method(:onSensor));
I tried in the initialize() and onStart(state) method, but still I get the error shown above.
CIQ apps of type "watch face" do not have access to sensors in that manner. Instead you need to use the methods available in the Activity and/or ActivityMonitor modules.
If the watch device is newer it will likely support calling this method, which returns an heart rate value that is updated every second:
Activity.getActivityInfo().currentHeartRate()
Otherwise, you can call this method and use the most recent value, which will be the heart rate within the last minute:
ActivityMonitor.getHeartRateHistory()
In both cases you will need to check for a null value, which will happen if the sensor is not available or the user is not wearing the watch.
