EST Monitoring Manager in Background

Hello,
I´m having trouble implementing the Monitoring Manager when the App is running in the Background.
didEnterRangeOfIdentifier and didExitRangeOfIdentifier are simply not called when the app is in background. With the “Display notifications, based on Estimote Monitoring” Demo App from the estimote cloud it works but I can´t implement it in my app.
I have Background Modes ON and “Uses Bluetooth LE accessory” checked.
I also have the “NSLocationAlwaysUsageDescription” in the Info.plist.

What could be missing? In foreground it works fine. Here´s my AppDelegate.swift:

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, ESTMonitoringManagerDelegate {
    
    let monitoringManager = ESTMonitoringManager()

    
    
    /////////////////////////////////////////////////
    ///////////// ENTER / EXIT LOGIC ////////////////
    /////////////////////////////////////////////////
    

    
    func monitoringManager(manager: ESTMonitoringManager, didEnterRangeOfIdentifier identifier: String) {
        print("ENTER Location")
        let notification = UILocalNotification()
        notification.alertBody = "ENTER Location"
        notification.soundName = "Default"
        UIApplication.sharedApplication().presentLocalNotificationNow(notification)
    }
    func monitoringManager(manager: ESTMonitoringManager, didExitRangeOfIdentifier identifier: String) {
        print("EXIT Location")
        let notification = UILocalNotification()
        notification.alertBody = "EXIT Location"
        notification.soundName = "Default"
        UIApplication.sharedApplication().presentLocalNotificationNow(notification)
    }
    
    func monitoringManager(manager: ESTMonitoringManager, didFailWithError error: NSError) {
        print("error")
        print(error)
    }
    
    

    
    
    
    /////////////////////////////////////////////////
    ///////////// ENTER / EXIT LOGIC ////////////////
    /////////////////////////////////////////////////
    ////////////////// END END END //////////////////
    /////////////////////////////////////////////////
    
    

    

    var window: UIWindow?
    
    
    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        
        


        ESTConfig.setupAppID("***", andAppToken: "***")
        
        self.monitoringManager.delegate = self
        self.monitoringManager.startTurboMode()
        self.monitoringManager.startMonitoringForIdentifier("***", inProximity: .Near)
        

        return true
    }
    
    

    func applicationWillResignActive(application: UIApplication) {
        // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
        // Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
    }

    func applicationDidEnterBackground(application: UIApplication) {
        // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
        // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
    }

    func applicationWillEnterForeground(application: UIApplication) {
        // Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.

    }

    func applicationDidBecomeActive(application: UIApplication) {
        // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.

    }

    func applicationWillTerminate(application: UIApplication) {
        // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
    }
