IOS background problem

[Dionysios]

Hi, I have a small project which requires ibeacons ranging in the foreground and monitoring with local notifications on the background. The plugin works great on Android but on IOS once I put the app on the background nothing happens. I looked the issue #53 but no luck. Here is the code. Any help is appreciated. Thanks in advance!

app.startScanForBeacons = function() { console.log('startScanForBeacons');

var delegate = new locationManager.Delegate();

delegate.didStartMonitoringForRegion = function(pluginResult){ console.log('Call monitoring'); app.didBeaconsInRegion(pluginResult); };

// Called when monitoring and the state of a region changes. // (Not used in this example, included as a reference.) delegate.didDetermineStateForRegion = function(pluginResult){ //console.log('didDetermineStateForRegion: ' + JSON.stringify(pluginResult)) };

delegate.didStartRangingBeaconsInRegion = function(pluginResult){ console.log('didDetermineStateForRegion: ' + JSON.stringify(pluginResult)) };

delegate.didRangeBeaconsInRegion = function(pluginResult){ console.log('didDetermineStateForRegion: ' + JSON.stringify(pluginResult)) // app.didBeaconsInRegion(pluginResult); };

// Set the delegare object to use. locationManager.setDelegate(delegate) // Request permission from user to access location info. // This is needed on iOS 8. locationManager.requestAlwaysAuthorization();

// Start monitoring and ranging our beacons. for (var r in app.beaconRegions) { var region = app.beaconRegions[r]

var beaconRegion = new locationManager.BeaconRegion( region.id, region.uuid, region.major, region.minor)

// Start monitoring.
locationManager.startMonitoringForRegion(beaconRegion)
.fail(console.error)
.done()

// Start ranging.
locationManager.startRangingBeaconsInRegion(beaconRegion)
.fail(console.error)
.done()

} } // Display pages depending of which beacon is close. app.didBeaconsInRegion = function(pluginResult) {

i have the same problem

Any solutions? I would love to use this plugin for a new project I have coming up but if this isn't working its a bit of a deal breaker for me.

i got a notification when app is colsed today but still testing I have de.appplant.cordova.plugin.local-notification and com.unarin.cordova.beacon installed looks like this var app = (function() { // Application object. var app = {};

// Specify your beacon UUIDs here.
var regions =
[
    // Estimote Beacon factory UUID.
    {uuid:'xxx'}
];

// Dictionary of beacons.
var beacons = {};

// Timer that displays list of beacons.
var updateTimer = null;

app.initialize = function()
{
    document.addEventListener('deviceready', onDeviceReady, false);
};

function onDeviceReady()
{
    // Specify a shortcut for the location manager holding the iBeacon functions.
    window.locationManager = cordova.plugins.locationManager;

    // Start tracking beacons!
    startMonitoring();

    // Display refresh timer.
    //updateTimer = setInterval(displayBeaconList, 500);
}

function startMonitoring()
{

    window.plugin.notification.local.cancelAll();
    //window.plugin.notification.local.add({ message: 'startScanForBeacons' });

    var createLocalNotification = function (message) {
        window.plugin.notification.local.add({
            title:   'iBeacon',
            message: message
        });
    };

    // specified below.
    var delegate = new locationManager.Delegate();

I added these lines var notifyEntryStateOnDisplay = true; var beaconRegion = new cordova.plugins.locationManager.BeaconRegion(identifier, uuid, major, minor, notifyEntryStateOnDisplay);

and change testing device from an ipad mini to an iphone 5 and it started working for me. If you still have problems go through #53

Hi, i have some questions:

1. is it possible do notify only if the app is closed or runs in background?
2. I want to notify the user only one time ('please open the app') if he enters a region of a single beacon the first time. If the app is running he should not be notified.
3. How can i check the distance to the beacon if the app runs in background in didEnterRegion function, so that i can say if entered a beaconregion and the distance to the beacon is closer than 4meter, createLocalNotification

like

delegate.didEnterRegion = function(pluginResult) { if (app runs in background mode && beacon.distance < 4meter && userisnotalreadynotified == false){ createLocalNotification('didEnterRegion: ' + JSON.stringify(pluginResult))

   var userisnotalreadynotified = true

} };

does someone maybe have a codesnippet for that?

greez & thx 4 help Sebastian

Setting up the iBeacon regions like this didn't change a thing

new cordova.plugins.locationManager.BeaconRegion(identifier, uuid, major, minor, true);
