Enable heartbeat to be sent automatically with async and Http Requests #1245

danielgomezrico · 2024-03-08T05:33:25Z

We need to keep calling our server with the latest know location every x seconds, even if the device is stationary, and we are using config async to call a service for that.

What we need to know how to do is that when the motion stops, the HTTP server stops being called and the heartbeat starts sending signals to the headless service or the listener. But they are not been sent to the HTTP server, it just beats.

It does make sense to me that this is the default behavior since it is beat, right? But for our use case, we still have to call the service when the beat is called, and so, how can we set up the library to still call the HTTP service even for heartbeat locations?

Your Environment

Plugin version: 4.13.5
Platform: iOS And Android
OS version: ios 12 > and android 9 >
Device manufacturer / model:
Flutter info (flutter doctor): flutter 3.16.4 and dart 3.2.3
Plugin config:

Config(
      // Run setup
      autoSync: true,
      foregroundService: true,
      stopOnTerminate: false,
      startOnBoot: true,
      desiredAccuracy: Config.DESIRED_ACCURACY_HIGH,
      reset: true,
      enableHeadless: true,

      // Force updates every x milliseconds ignoring distance
      disableMotionActivityUpdates: true,
      allowIdenticalLocations: true,
      useSignificantChangesOnly: false,
      activityRecognitionInterval: 0,
      isMoving: true,
      disableElasticity: remoteConfig.disableElasticity,
      distanceFilter: remoteConfig.distanceFilter,
      heartbeatInterval: 10,
      locationUpdateInterval: remoteConfig.locationUpdateIntervalMilliseconds,
      fastestLocationUpdateInterval: remoteConfig.locationUpdateIntervalMilliseconds,
      preventSuspend:  true,

      // Url Request
      url: url,
      httpRootProperty: '.',
      headers: { 'Content-Type': 'application/json' },
      params: { 'reference_type': 'id' },

      // Logging
      debug: true,
      logLevel: Config.LOG_LEVEL_VERBOSE,
    );

Expected Behavior

The HTTP service is executed for the URL in the setup for the new locations and for all heartbeat events

Actual Behavior

The HTTP service is executed for the URL in the setup only for the new locations.

The heartbeat listeners and headless function are executed, but not the automatic HTTP service that is set up via the config.

Steps to Reproduce

Run the service
Check that it starts emitting, but it stops at some time with:

And then theres only heartbeat but no HTTP requests:

Context

My company needs to have the location of the hole travel with times less than 5 minutes between each call, and even if the car is stopped, so we are trying to fetch them every 10 seconds or 30 to try to make it into that time window.

The text was updated successfully, but these errors were encountered:

We need to keep calling our server with the latest know location every x seconds, even if the device is stationary

Why?? You're fighting an uphill battle. The OS doesn't want you to do this.

This sort of behaviour is the reason that https://dontkillmyapp.com exists.

If the plug-in says the device is stationary, it's pointless to keep reporting "here I am", "here I am", "here I am", wasting the device battery.

christocracy · 2024-03-08T05:41:04Z

You're responsible for requesting your own location in your onHeartbeat by calling .getCurrentPosition. The plug-in does NOT turn on location-services at all while stationary. The location provided to onHeartbeat is the "last known location".

You'll never get what you want on iOS and Android is becoming more strict with "exact" timers.

Thanks for answering, that totally makes sense, but our business is related to moving other companies' packages. One of our providers is now requiring us to report the location in a time window less than 5 minutes per point in the hole of travel. We are struggling to make that happen. Do you think that trying to do this will make the OS to kill the service? Even if we are not accessing the GPS but just the latest known position and sending it back?

The easiest thing to do, is simply call .changePace(true) with a really large stopTimeout, forcing location-services to stay on, preventing the plug-in from entering the stationary state.

With location-services ON, your app continues to spin the CPU and your code is completely alive to run your own Dart timers to call .getCurrentPosition.

Be sure to call .changePace(false) when a "delivery" is complete or you'll kill the battery.
