Locations are reported infrequently

[jwasnoggin]

Describe the bug Using this plugin in my app, locations are being recorded much less frequently than I expect. I have interval set to 60000 (1 minute), and stationaryRadius and distanceFilter set to 10. I would expect an update close to every minute, but instead it was only happening every 3-10 minutes typically. Sometimes if I opened Google Maps it would then send a location (I guess because the GPS was activated), but not always.

Is there any way I can set an expected frequency and have the app honour that?

My full config:

{
    locationProvider: BackgroundGeolocation.DISTANCE_FILTER_PROVIDER,
    desiredAccuracy: BackgroundGeolocation.MEDIUM_ACCURACY,
    stationaryRadius: 10,
    distanceFilter: 10,
    stopOnTerminate: false,
    notificationTitle: 'Background tracking',
    notificationText: 'enabled',
    debug: false,
    interval: frequencySeconds * 1000,
    startForeground: true,
    pauseLocationUpdates: false,
    saveBatteryOnBackground: false,
    maxLocations: 1000,
    url,
    syncUrl,
    httpHeaders,
    postTemplate
}

Expected behavior The app should report a location every minute (as long as the speed is less than 60 m/s).

I would consult the plugin's logs to see what might have caused this, also I would recommend trying all kind of configurations. If nothing helps feel free to add prints in the code. The plugin mainly send back what the OS sends it...

I had a look at the logs, doesn't seem to be any errors. There are a few gaps where nothing happens for several minutes, for example here between 17:36 and 17:45. The tracking was supposedly running the whole time.

It might be related to distance? You also have medium accuracy which might be affecting somehow, IDK, it's complicated... Adding logs to the java code might help I guess...
