react-native-beacons-manager: iOS montioring when the app is killed/in background mode does not work

Version

1.0.7

Platform

iOS

OS version

iOS 11.0.2

Steps to reproduce


listener = DeviceEventEmitter.addListener(
        'beaconsDidRange',
        (data) => {

          PushNotification.localNotificationSchedule({
            message: 'Did Detect Beacon', // (required)
            date: new Date(Date.now())
          })
        }
)

Beacons.requestAlwaysAuthorization()
Beacons.startMonitoringForRegion(region)
Beacons.startRangingBeaconsInRegion(region)
Beacons.startUpdatingLocation()

Expected behavior

Beacon should be detected also when the app is killed/in background mode

Actual behavior

The listener callback does not get called (it does get called on foreground)

We had the same problem.

Adding self.locationManager.allowsBackgroundLocationUpdates = YES; to the init method of RNIBeacon.m solved the problem.

https://developer.apple.com/documentation/corelocation/cllocationmanager/1620568-allowsbackgroundlocationupdates

maybe some function like

RCT_EXPORT_METHOD(allowsBackgroundLocationUpdates:(BOOL)allow)
{
  self.locationManager.allowsBackgroundLocationUpdates = allow;
}

would be helpful. This would allow the developer to control, when ranging in background really needed.

I just solve it by change the privacy. as your suggested, both “location always use” + “location when in use” description must fill something to make it works in the plist!

Hi All,

I enabled background update by setting BeaconsManager.allowsBackgroundLocationUpdates(true) in the beginning of componentWillMount

I would like to know if this suppose to work for only single region or multi region as I noticed when I am sending ranging information from multi region I will only get one region update instead of all of it. Or if I am doing something wrong so not all then not all region ranging update are send while in phone is locked.

Thank you 😄
