HoloLens TCP Socket No Connection

i have been trying for some days now to create a TCP connection from a HoloLens to my local machine. I know that there are many solutions out there, but i have no clue why i cannot connect to the device. Maybe anyone could help me or advise me what i am doing wrong.

Here is my Code so far:

Code (CSharp):

1. using UnityEngine;
2. #if WINDOWS_UWP
3. using System;
4. using System.Collections;
5. using System.Collections.Generic;
6. using System.IO;
7. using System.Threading.Tasks;
8. using Windows.Networking;
9. using Windows.Networking.Sockets;
10. using Windows.Storage.Streams;
11. using Windows.Foundation;
12. #endif
13.  
14. public class DataListener : MonoBehaviour
15. {
16. #if WINDOWS_UWP
17.  
18.   private StreamSocket _socket;
19. #endif
20.  
21.   private void Start()
22.   {
23.     SetupTcpConnection();
24.   }
25.  
26.   //HoloLens Code
27.   private void SetupTcpConnection()
28.   {
29. #if WINDOWS_UWP
30.  
31.     if (_socket != null)
32.       return;
33.  
34.     _socket = new StreamSocket();
35.  
36.     var hostName = new HostName("192.168.8.102");
37.     var socketConnectionAwaiter = _socket.ConnectAsync(hostName, "11000");
38.     var handler = new                     AsyncActionCompletedHandler(SocketConnectionCompleted);
39. socketConnectionAwaiter.Completed = handler;
40. #endif
41.  
42.   }
43. #if WINDOWS_UWP
44.  
45.   void SocketConnectionCompleted(IAsyncAction action, AsyncStatus status)
46.   {
47.     if (status != AsyncStatus.Completed)
48.     {
49.       _socket.Dispose();
50.       _socket = null;
51.       return;
52.     }
53.  
54.     // Read the data
55.     using (var reader = new     StreamReader(_socket.InputStream.AsStreamForRead()))
56.     {
57.       var data = reader.ReadToEnd();
58.  
59.       //then read data
60.  
61.     }
62.   }
63. #endif
64.  
65. }

C# Application Code:

Code (CSharp):

1. public static void StartClient3()
2. {
3.     var listener = new
4.     TcpListener(IPAddress.Any, 11000);
5.     var connectionHandler = new ConnectionHandler();
6.  
7.     var workerThread =
8.         new Thread(connectionHandler.HandleConnections);
9.     workerThread.Start(listener);
10.  
11.     while (!Console.KeyAvailable) { }
12.  
13.     Console.WriteLine("Shutting down");
14.     listener.Stop();
15.     workerThread.Abort();
16. }
17.  
18. public class ConnectionHandler
19. {
20.     TcpListener _listener;
21.  
22.     public void HandleConnections(object dataToPass)
23.     {
24.  
25.         _listener = dataToPass as TcpListener;
26.         if (_listener == null)
27.             return;
28.  
29.         _listener.Start();
30.  
31.         Console.WriteLine("We are waiting for a connection");
32.         while (true)
33.         {
34.             var client = _listener.AcceptTcpClient();
35.  
36.             Console.WriteLine("We are connected");
37.  
38.             var dataToSend = "SampleString";
39.             using (var writer = new StreamWriter(client.GetStream()))
40.             {
41.                 writer.Write(dataToSend);
42.                 writer.Flush();
43.             }
44.             client.Close();
45.         }
46.     }
47. }

I get the IP (192.168.8.102) from my local machine from ipconfig, so this should be the right one. I cannot simply connect to HoloLens and I have no idea why.

I also checked the settings in Unity like InternetClientServer, PrivateNetworkClientServer, InternetClient.

Is there anything what I forget. I would really appreciate your Help!

Cheers, Pat

 

I have same problem.

 

Did you ever figure this out?
