Hi,

I have checked the WindowsBeacons.sln, and run the Bluetooth Beacon Interactor in Win10, the beacons info in the listview don't updeted immediately. My beacons brocast the advertismement frame every 500ms, but the rssi and timestamp don't updated in 500ms.
I dont know why, please!
thanks!

I've got the same/a similar problem I'm currently working on.
In a file called MainPage.xaml.cs in a sample project I found the following comment regarding the BeaconManagerOnBeaconAdded method:

    /// This event will only be invoked once, the very first time a beacon is discovered.
    /// For more fine-grained status updates, subscribe to changes of the ObservableCollection in
    /// BeaconManager.BluetoothBeacons (_beaconManager).
    /// To handle all individual received Bluetooth packets in your main app and outside of the
    /// library, subscribe to AdvertisementPacketReceived event of the IBluetoothPacketProvider
    /// (_provider).

But I really don't know how to implement this functionality. I would be glad if somebody had a solution for this.
The AdvertisementPacketReceived event is the unformatted event of the Windows.Devices.Bluetooth API (I think) and therefore a step back, as we are using the Universal Beacon Library for receiving user-friendly formatted Advertisements.
Therefore it must be something with this ObservableCollection, but I can't figure it out.
