Xamarin Forms Sockets

I don't get it, my friend and I are developing an API and our WebSocket services works, but not the mobile side.. I tried with a couple of clients, on the web, our echo messaging and everything works.

The thing is, I mean, the things seem like the socket is mono-directional. I tried the example of https://github.com/rdavisau/sockets-for-pcl#a-tcp-client:

var address = "127.0.0.1";
var port = 11000;
var r = new Random(); 

var client = new TcpSocketClient();
await client.ConnectAsync(address, port);

// we're connected!
for (int i = 0; i<5; i++)
{
    // write to the 'WriteStream' property of the socket client to send data
    var nextByte = (byte) r.Next(0,254);
    client.WriteStream.WriteByte(nextByte);
    await client.WriteStream.FlushAsync();

    // wait a little before sending the next bit of data
    await Task.Delay(TimeSpan.FromMilliseconds(500)); 
}

await client.DisconnectAsync();

First, after I get connected with this :

public async void ConnectSocketToAPIAsync()
    {
        SocketClient = new TcpSocketClient();
        await SocketClient.ConnectAsync("my.ws.service", 4242);
        ActiveSocketExchange();
    }

    public async void ActiveSocketExchange()
    {
        var bytesRead = -1;
        var buf = new byte[1];

        while (bytesRead != 0)
        {
            bytesRead = await SocketClient.ReadStream.ReadAsync(buf, 0, 1);
            if (bytesRead > 0)
                MessagingCenter.Send((App)Current, SOCKET_Message, System.Text.Encoding.UTF8.GetString(buf, 0, bytesRead));
        }
    }

Everything's fine, my TcpClient is well initialized (even the web-link becomes the http's API addr)

From my page view, when I'm done writing my text, I'm pressing the done button of the keyboard and this code is called:

private void InitSocketPart()
    {
        MessagingCenter.Subscribe<App, string>((App)Application.Current, App.SOCKET_Message, (sender, text) =>
        {
            SocketResponseText = text;
        });
    }

    private async void OnTextCompleted(object sender, EventArgs ea)
    {
        var bytes = Encoding.UTF8.GetBytes(TextToSend);
        try {
            if (App.SocketClient.WriteStream.CanRead)
                Debug.WriteLine("canRead");
            if (App.SocketClient.WriteStream.CanWrite)
                Debug.WriteLine("canWrite");

            App.SocketClient.WriteStream.Write(bytes, 0, TextToSend.Length);
            App.SocketClient.WriteStream.Flush();
        } catch (Exception e)
        {
            Debug.WriteLine(e);
        }
    }

So now CanWrite && CanRead are true, but nothing at all happens, even with the use of Async methods... Why so? I don't get it..

The use of messaging center is just to have only one point of incoming message. I'm using it for other things and it works perfectly

Thank for any help..
