TCP Client on Hololens Emulator ?

ChristophMarkoChristophMarko ✭
in Questions And Answers

Hy guys,

I'm trying for 3 hours to get a TCP Client running on the hololens emulator (PC) and sends a string over wifi to a MATLAB TCP Server running on my Surface. Both are in the same wlan but I'm not able to send the string.
I tested my settings with my UDP Client on the hololens emulator and the udp server in MATLAB but this works.
I used the recommended files from Microsoft:
https://docs.microsoft.com/en-us/windows/uwp/networking/sockets

Please help me :(

    The funny thing about the error is that I have access to the internet but cannot send a string to my Surface over TCP ??? I checked my firewall settings and I also created a rule for this port (incoming and outcoming). :s:s:s:s

    this is my code :

    using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;
    using System;
    using System.IO;

    if !UNITY_EDITOR

    using Windows.Networking.Sockets;
    using Windows.Networking;
    using Windows.Networking.Connectivity;

    endif

    public class NewBehaviourScript2 : MonoBehaviour {

    if !UNITY_EDITOR

    private async void Start()
{

    Windows.Networking.Sockets.StreamSocket socket = new Windows.Networking.Sockets.StreamSocket();
    Windows.Networking.HostName server = new Windows.Networking.HostName("192.168.0.xx");
    string serverPort = "8000";
    await socket.ConnectAsync(server, serverPort);

    Stream streamOut = socket.OutputStream.AsStreamForWrite();
    StreamWriter writer = new StreamWriter(streamOut);
    string message = "Hallo Server";
    await writer.WriteLineAsync(message);
    await writer.FlushAsync();



}

    else

    // Use this for initialization
void Start()
{

}

    endif

    }
