Using the bluetooth API in j2me, I want to send a message to another mobile phone. I have been able to discover devices and services on the corresponding devices. I have also been able to connect to the services however when I try to send a message from the server to the client. The message is written but the client does not seem to receive it ..
have I erred somewhere bcause these are codes from the Net?
Code:
public void startServer() throws IOException { UUID uuid = new UUID("1101", false); //Create the service url String connectionString = "btspp://localhost:" + uuid + ";name=xyz"; //open server url StreamConnectionNotifier streamConnNotifier = (StreamConnectionNotifier) Connector.open(connectionString); //Wait for client connection System.out.println("\nServer Started. Waiting for clients to connect..."); StreamConnection connection = streamConnNotifier.acceptAndOpen(); RemoteDevice dev = RemoteDevice.getRemoteDevice(connection); System.out.println("Remote device address: " + dev.getBluetoothAddress()); System.out.println("Remote device name: " + dev.getFriendlyName(true)); Survey.setTitle(dev.getFriendlyName(true)); //read string from spp client try { DataInputStream in = connection.openDataInputStream(); OutputStream writer=connection.openDataOutputStream();
String str="";
TextField textfield;
for (int i=0;i<questions.size();i++){
textfield = (TextField) questions.elementAt(i);
str += formatSurvey(textfield,i)+"&";
}
writer.write(str.getBytes(), 0, str.getBytes().length);
writer.flush();
System.out.println("Written to client "+str);
System.out.println("Reading "+in.readUTF());
try {
displaySurveyresults(str);
}
catch(Exception e){
System.out.println(e.getMessage());
}
streamConnNotifier.close();
}
catch(Exception e){
System.err.println(e.getMessage());
}
}
public void servicesDiscovered(int transID, ServiceRecord[] servRecord) { switchDisplayable(null , getList1()); list1.append(servRecord.toString(), null); System.out.println("Service discovered..."+servRecord.toString()); for (int i=0;i
System.out.println("Test2");
DataInputStream in = con.openDataInputStream();
System.out.println("Test3"+in.readUTF());
//con.openDataOutputStream().write(142);
System.out.println("Test4 "+in.available());
byte[] bte=new byte[in.available()];
System.out.println("Test5 "+bte.length);
in.read(bte);
System.out.println("Test6");
for (int l=0;l<bte.length;l++){
System.out.println(bte[i]);
System.out.println("Test7");
stringItem.setText(stringItem.getText()+1 + bte[i]);
}
OutputStream outStream=con.openOutputStream();
OutputStreamWriter writer = new OutputStreamWriter(outStream);
writer.write("Vimal");
} catch (IOException ex) {
ex.printStackTrace();
}
}
}
