Socket TCP / bluetooth

Bonjour;
le but de mon projet se de faire communiquer entre appareil android et pc via bluetooth, j'ai un programme en java qui joue le role d'un serveur java et j'ai le code coté android, utilisant les sockets TCP, mais pour mon projet , il est demander de faire ca avec le protocole Bluetooth, comment puisse je remplacer les sockets TCP par les sockets Bluetooth, et que-est-ce qu'il faut chenger , voila le code coté serveur (pc):
package com.oumaya.app.serveurBluetooth;

import java.net.*;


public class Server {

public static void main(String[] args) {

int nreq = 1;
try
{
ServerSocket sock = new ServerSocket (8080);
for (;;)
{
Socket newsock = sock.accept();
System.out.println("Creating thread ...");
Thread t = new ThreadHandler(newsock,nreq);
t.start();
}
}
catch (Exception e)
{
System.out.println("IO error " + e);
}
System.out.println("End!");
}
}

*********************************************** avec :
package com.oumaya.app.serveurBluetooth;

import java.io.*;
import java.net.*;

class ThreadHandler extends Thread {
Socket newsock;
int n;

ThreadHandler(Socket s, int v) {
newsock = s;
n = v;
}


public void run() {
try {

PrintWriter outp = new PrintWriter(newsock.getOutputStream(), true);
BufferedReader inp = new BufferedReader(new InputStreamReader(
newsock.getInputStream()));

outp.println("Hello :: enter QUIT to exit \n");
boolean more_data = true;
String line;

while (more_data) {
line = inp.readLine();
System.out.println("Message '" + line + "' echoed back to client.");
if (line == null) {
System.out.println("line = null");
more_data = false;
} else {
outp.println("From server: " + line + ". \n");
if (line.trim().equals("QUIT"))
more_data = false;
}
}
newsock.close();
System.out.println("Disconnected from client number: " + n);
} catch (Exception e) {
System.out.println("IO error " + e);
}

}
}
