export.lua socket fail when listener is not up

[karpiyon]

Hi,

I am trying to export DCS data. I want to transfer data every 500ms and try to receive it in my c# plugin when i need it. I am new to this so I try to follow existing examples. When I start the listener before DCS starts (the client) the connection is working. However, I want to open start the listener after the client starts transmitting or be able to open close it.

 

on the client(DCS) i use:

 

socket = require("socket")
IPAddress = "127.0.0.1"
Port = 31090

MySocket = socket.try(socket.connect(IPAddress, Port))
MySocket:setoption("tcp-nodelay",true) 

The error i get from that client (when my listener is not set is the:

 

Lua::Config: Call error LuaExportStart:<LUA_TTABLE>
stack traceback:
   [C]: ?
   [C]: in function 'try'

on this line:

 

MySocket = socket.try(socket.connect(IPAddress, Port))

My test c# code is something like this:

 

var listener = new TcpListener(IPAddress.Parse("127.0.0.1"), 31091);
               listener.Start();
               Thread.Sleep(700);

               if (!listener.Pending())
               {
                   vaProxy.WriteToLog("Sorry, no connection requests have arrived", "Red");
               }
               else
               {
                   vaProxy.WriteToLog("Server started.", "Green");
                   vaProxy.WriteToLog("Waiting for DCS connection...", "Green");
                   var client = listener.AcceptTcpClient();
                   vaProxy.WriteToLog("DCS connected :-)", "Green");

                   var reader = new StreamReader(client.GetStream());
                   var writer = new StreamWriter(client.GetStream());
                   var s = string.Empty;

                   s = reader.ReadLine();
                   vaProxy.WriteToLog(s, "Blue");

                   reader.Close();
                   writer.Close();
                   client.Close();
               }
               listener.Stop();
