Not receiving continuous updates

[romuye123]

1] Thanks for the superb example, it is working perfectly fine. But i am facing a small problem.
I have added timestamp to your foreground watcher example:

String timeStamp = GetTimestamp(DateTime.Now);
Debug.WriteLine("TS: " + timeStamp  + " UUID: " +beacon.UUID.ToString()+" Major: "+beacon.Major+" Minor:"+beacon.Minor+" Power: "+ beacon.TxPower+ " Rssi: "+RawSignalStrengthInDBm+" Distance:"+ beacon.Distance);

And the updates i am receiving from Beacon are not continuous. Have a look at below output:

There is a random gap of 3-4 seconds between each update. Sometimes even larger of 15+seconds, notice the last 2 outputs. What could be the problem ? Is there anything wrong ?

NOTE: The iBeacon is broadcasting data every 900ms. And i have confirmed this by developing Android and iOS app.

2] Background watcher project does not shows anything on screen. Not even on debug and no errors at all.
