IntervalTrigger not working

[sc00n]

When I use interval trigger it works for a few seconds and then it stops. For example when I have the following code in local_study_protocol_managaer.dart:

    protocol.addTriggeredTask(
        IntervalTrigger(period: Duration(milliseconds: 300)),
        BackgroundTask()
          ..addMeasure(Measure(type: SensorSamplingPackage.PEDOMETER)),
        phone);

I get the following output:

So I have output for a few seconds, and then it completely stops. The same holds for when I use the intervaltrigger with ContextSamplingPackage.LOCATION or DeviceSamplingPackage.DEVICE . The app is still open and I see no errors. I used the example app from GitHub.

[sc00n]

The following also doesn't work:

    Measure loc =Measure(type: ContextSamplingPackage.GEOLOCATION)..overrideSamplingConfiguration = PeriodicSamplingConfiguration(
      interval: const Duration(seconds: 2),
      duration: const Duration(seconds: 1),
    );

What did work for me was using

LocationService locationService = LocationService(interval: Duration(seconds: 10));

pedometer also kind of shoots with every step. DeviceSamplingPackage.DEVICE I still have to figure out. In general I like it more when I can just use an interval (e.g. every 10 seconds) to measure something. This is mainly because of the gaps and the app being killed. If I have no information I don't know if nothing happened or the app was just killed.

[sc00n]

I think there is just in general something wrong with the interval trigger. Also the following doesnt work while it is one of the examples in the example app (I only changed the duration for testing purposes).

  protocol.addTriggeredTask(
        IntervalTrigger(period: Duration(seconds: 5)),
        BackgroundTask()
          ..addMeasure(Measure(type: ContextSamplingPackage.WEATHER)),
        weatherService);

When I use interval trigger it works for a few seconds and then it stops. For example when I have the following code in local_study_protocol_managaer.dart:

    protocol.addTriggeredTask(
        IntervalTrigger(period: Duration(milliseconds: 300)),
        BackgroundTask()
          ..addMeasure(Measure(type: SensorSamplingPackage.PEDOMETER)),
        phone);

I get the following output:

So I have output for a few seconds, and then it completely stops.

The IntervalTrigger is intended to be used when sampling a single piece of measure - the so-called "One Time" (OT)measure. This is in contrast to the measure which are "Event Based" (EB). In the overview of measures, you can see which measures are OT and EB.

Since the PEDOMETER measure is a EB, it does not make sense to use an IntervalTrigger - this measure collect a step count event each time "some" steps are detected by the phone (when this happens depends on the phone and its step counter hardware). Hence, a PEDOMETER measure should be triggered always (ImmediateTrigger) or - if you want it to happen with a interval - you can use a PeriodicTrigger which runs periodically with a fixed period.

However, it does not make sense to collect step count on such a short time window ( 300 milliseconds) -- the user will not be able to take any steps in such a short timeframe. So - I would make something like:

 protocol.addTriggeredTask(
        PeriodicTrigger(period: Duration(minutes: 30), duration: Duration(minutes: 10),
        BackgroundTask()
          ..addMeasure(Measure(type: SensorSamplingPackage.PEDOMETER)),
        phone);

which would collect step counts for 10 minutes every half hour.

The same holds for when I use the intervaltrigger with ContextSamplingPackage.LOCATION or DeviceSamplingPackage.DEVICE . The app is still open and I see no errors. I used the example app from GitHub.

I think the problem here is that the sampling time is extremely short - 300 miliseconds - the GPS will never be able to collect any location data in such a short time frame

pedometer also kind of shoots with every step

Yes - this is how this sensor works on most phones.

  protocol.addTriggeredTask(

          ..addMeasure(Measure(type: ContextSamplingPackage.WEATHER)),
        weatherService);

Note that in order to use the Open Weather web service, you need a API key. See the README file for documentation of this. You can also look at the example to see how a WeatherService is created and added to the protocol.

[sc00n]

Thank you for your replies!

I'll start with your last reply. The problem is that it works once (showing that the API is correctly connected) and then stops. I used exactly the code from the example, with a filled in API key:

    // Define the online weather service and add it as a 'device'
    WeatherService weatherService =
    WeatherService(apiKey: '066c4ff8fe6a59b17da65a3f96544b80');
    protocol.addConnectedDevice(weatherService);

    // Add a background task that collects weather every 30 miutes.
    protocol.addTriggeredTask(
        IntervalTrigger(period: Duration(seconds: 5)),
        BackgroundTask()
          ..addMeasure(Measure(type: ContextSamplingPackage.WEATHER)),
        weatherService); 

With location the following code doesn't work. It again works once (one output), and then stops.

    LocationService locationService = LocationService();
    protocol.addConnectedDevice(locationService);

    // Add a background task that collects location on a regular basis
    protocol.addTriggeredTask(
        IntervalTrigger(period: Duration(seconds: 15)),
        BackgroundTask()
          ..addMeasure(Measure(type: ContextSamplingPackage.LOCATION)),
        locationService);

The following however does work (using geolocation and setting interval in location service):

    LocationService locationService = LocationService(interval: Duration(seconds: 15));
    protocol.addConnectedDevice(locationService);

    // Add a background task that collects location on a regular basis
    protocol.addTriggeredTask(
        ImmediateTrigger(),
        BackgroundTask()
          ..addMeasure(Measure(type: ContextSamplingPackage.LOCATION)),
        locationService);

Showing that 15 seconds is not too fast to sample but that the IntervalTrigger somehow fails. So for location, it doesn't really matter if IntervalTrigger doesn't work as there is a work around. This can however not be used to the weather measure or others.

I also tried CONNECTIVITY and APP_USAGE (other OT). They all give one measurement and then stop.

Steps to reproduce:

1. Import Example app (https://github.com/cph-cachet/carp.sensing-flutter.git)
2. Open apps/carp_mobile_sensing_app/ (make sure its a flutter project)
3. In pubspec.yaml change _researchpackage to _researchpackage: ^1.2.0 (otherwise pub get didn't work)
4. Do pub get
5. Go to getStudyProtocol in Sensing/local_study_protocol_mananger.dart
6. Replace everything after protocol.addMasterDevice(phone); with the following code (to focus on one sensor):

    LocationService locationService = LocationService();
    protocol.addConnectedDevice(locationService);

    // Add a background task that collects location on a regular basis
    protocol.addTriggeredTask(
        IntervalTrigger(period: Duration(seconds: 15)),
        BackgroundTask()
          ..addMeasure(Measure(type: ContextSamplingPackage.LOCATION)),
        locationService);

    return protocol;

7. Run app using the command Flutter run . I am testing on an Android 12 Samsung.
8. Click on the play button to start sensing
9. After a couple of seconds, accept location to be accessed (while using app)

I then get the following output after a couple of minutes:

As you can see location is only measured once. As permission was not given in time, the location data is also not filled in. When I restart the app I again get one measurement, but now permission was given in time so it is filled in:

I have the same problem with other OT measurements, they all result in one measurement and then stop.

I reproduced this problem uses the steps above on a Xiaomi Mi 10T (Android 11) Lite and also found it only ran once. Additionally, I got a warning:

I also made sure all permissions were given and battery optimisation was disabled. I then restarted to app to start in a clean slate but the behaviour was the same. Pausing and then restarting sensing (by using the green button in the app) again produced a single measurement.

I've just found that the same problem applies for the PeriodicTriggerExecutor ... will fix it now.

Has been fixed now - released as version 0.40.5
