Body
copied!<p>I am starting on Android and in my first application I need to establish a communication between and android table a PC. The communication is direct by staqtic IPs as I need that when I have several PCs and tablets each table only communicates with its PC.</p> <p>The communication from the tablet to the Pc is already working but from the PC to the table I cannot get data transfered</p> <p>Android side</p> <pre><code>public class Server implements Runnable { @Override public void run() { while (always==true) { while(start2==false) { } try { InetAddress serverAddr = InetAddress.getByName("192.168.173.133"); updatetrack("\nServer: Start connecting\n"); //*DatagramSocket socket = new DatagramSocket(SERVERPORT2, serverAddr);/ DatagramSocket socket = new DatagramSocket(SERVERPORT2); byte[] buf = new byte[17]; DatagramPacket packet = new DatagramPacket(buf, buf.length, serverAddr, SERVERPORT2); //*DatagramPacket packet = new DatagramPacket(buf, buf.length);/ updatetrack("Server: Receiving\n"); socket.receive(packet); updatetrack("Server: Message received: '" + new String(packet.getData()) + "'\n"); updatetrack("Server: Succeed!\n"); start2=false; } catch (Exception e) { updatetrack("Server: Error!\n"); start2=false; } } } } </code></pre> <p>192.168.173.133 is the table IP and SERVERPORT2 is 4445 When I start the application it remains waiting for data after displaying "Server: Receiving" but </p> <p>C# code</p> <pre><code>public static void Main() { IPEndPoint iep2 = new IPEndPoint(IPAddress.Parse("192.168.173.133"), 4445); string hostname = Dns.GetHostName(); byte[] data = Encoding.ASCII.GetBytes(hostname); sock.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.Broadcast, 1); sock.SendTo(data, iep2); sock.Close(); } </code></pre> <p>I suppose that it is any silly think I am forgotten but after reading many forums and books I am stopped on this point</p> <p>Any advise will be welcome</p>
