[#VS2013] HowTo: Validate if a BlueTooth this device in range

Hello!

I’m still with the posts of BlueTooth with 32Feet, the truth is that you are giving me enough surprises and very nice some. The following code is a console that once app found one device Bluetooth that corresponds to a Windows Phone 8.1, is in charge to see if it is within a range of acceptable connection.

   1: class Program

   2:  {

   3:      static void Main()

   4:      {

   5:          var wp = GetWindowsPhoneBtDevice();

   6:          Console.WriteLine("{0}Press any key to validate if device is in range, or ESC to close the app", Environment.NewLine);

   7:          bool exit;

   8:          var i = 0;

   9:          do

  10:          {

  11:              i++;

  12:              ValidateIfDeviceIsOnRange(i, wp);

  13:              var cki = Console.ReadKey(true);

  14:              exit = cki.Key == ConsoleKey.Escape;

  15:          } while (!exit);

  16:      }

17:

  18:      private static void ValidateIfDeviceIsOnRange(int i, BluetoothDeviceInfo wp)

  19:      {

  20:          Console.WriteLine("   " + i + " validating device in range");

  21:          var inRange = true;

  22:          var fakeUuid = new Guid("{F13F471D-47CB-41d6-9609-BAD0690BF891}"); // A specially created value, so no matches.

  23:          try

  24:          {

  25:              wp.GetServiceRecords(fakeUuid);

  26:          }

  27:          catch (SocketException)

  28:          {

  29:              inRange = false;

  30:          }

  31:          Console.WriteLine("     In range: " + inRange);

  32:      }

33:

  34:      private static BluetoothDeviceInfo GetWindowsPhoneBtDevice()

  35:      {

  36:        // You can get this from my previous post ...

  37:      }

  38:  }

The code is quite simple, and the truth is that the result is 100% acceptable. The following video shows my 1520 Lumia where I change the status of BlueTooth ON / OFF and then as console app checks the State and shows the true / false.
