OTClient TCP/IP communication

[MagicWall]

Hi,
I have problem with TCP/IP communication betwen two otclients.

In first OTClient I create server:
otclient/server.cpp at master · edubart/otclient · GitHub

local Serv = nil

function testCreateServer()
    Serv = Server.create(7175)
end

In second OTClient I connect to the server and send something using protocol:
otclient/protocol.cpp at master · edubart/otclient · GitHub

local Send = Protocol.create()

function testConnectSend()
    Send:connect("127.0.0.1", 7175)
end

function testConnectSendMes()
    msg = OutputMessage.create()
    msg:addString('Hello World!')

    Send:send(msg)

    print('isConnected:  '..tostring(Send:isConnected())) --terminal show true
    print('isConnecting:  '..tostring(Send:isConnecting())) --terminal show false
end

Next I create in first OTClient listener but it doesn't work:

local List = Protocol.create()

function testConnectListener()
    List:connect("127.0.0.1", 7175)
end

function testConnectListenerOne()
    print('Recv:  '..List:recv())
end

--Or
testEventServer = {}
function testConnectListener()
    testEventServer['myId'] = cycleEvent(function()
        local xxx = List:recv()
        if xxx then
            print(xxx)
        end
    end, 1)
end

Terminal send (function testConnectListenerOne()) Error: command failed: /modules/terminal_scriptwrite/scripts/target.lua:75: attempt to concatenate a nil value.

Someone have idea how to received messages sended from second to first OTClient?

I check in Process Hacker (network) and I see:
Local Port: 7175 - Listener
Remote Port: 7175 - Established
Remote Port: 7175 - Established

So I think, I connect properly.

well this looks really interesting.. i'd like to help with that somehow if i can

are you thinking of creating gamerooms?
did you managed it to work already?

my guess is that io_service is not processing scheduled async operations (no .run or .poll is called on that bad boy).
In short, GraphicalApplication needs to be running in order to poll asio's requests.
