Xamarin Forms Sockets - sockets

Question

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..
