title: Reading raw data via Bluetooth
body: <p>I have a digital Human Interface Device that I'm trying to connect to using 32feet.net so I can read input data from it and process an output in my application. I've never programmed with bluetooth before and am learning as I go. </p>
  
  <p>I can connect my device to Windows 7 using the microsoft/broadcom stack no problem. I can also discover the device using 32feet.net but when I try to connect it I get an error. I made sure my stack was supported using BluetoothRadio.IsSupported Here is a code snippet:</p>
  
  <pre><code> var client = new BluetoothClient();
   var dlg = new SelectBluetoothDeviceDialog();
   DialogResult result = dlg.ShowDialog(this);
   if (result != DialogResult.OK)
   {
       return;
   }
   BluetoothDeviceInfo device = dlg.SelectedDevice;
   BluetoothAddress addr = device.DeviceAddress;
   Console.WriteLine(device.DeviceName);
   Guid serviceClass = BluetoothService.HumanInterfaceDevice;
   client.Connect(new BluetoothEndPoint(addr, serviceClass));
  </code></pre>
  
  <p>The last line causes the following error:
  A first chance exception of type 'System.Net.Sockets.SocketException' occurred in System.dll</p>
  
  <p>I've tried some other methods as well with client.Connect. I've tried using DiscoverDevices to get a DeviceInfo array and manually choosing the device out of that array and connecting to it. I've tried setting the serviceClass as Empty because that is what shows up when I use DeviceInfo.ClassOfDevice.Service. I've been able to connect the device to windows using DeviceInfo.SetServiceState(BluetoothService.HumanInterfaceDevice, true) but not able to get a stream from it.</p>
  
  <p>Even if I can get a data stream from the device after it's been connected in Windows, that would be fine. My goal here is simple to be able to read input from the device like a button press.</p>
