Bluetooth server and client

[ug94bxs]

Hello, I have setup a server on a pc and a client on a phone (6600) using java.

The code works fine, the phone searches for the serevr and sends and recives data.

However i want the server on the phone and the client on the pc. I have simply switrched
over the code however nothing happens. No exceptions are thrown, the pc find the phone (server)
but doesnt do anyuthing even though the pc opens a connection and writes to it!


The following code is running on the phone (works fine as a pc server)



public class BTServer{

private String serviceName = "BCal"; // service name
private UUID serviceUUID = new UUID("2d26618601fb47c28d9f10b8ec891363", false);


//private calenderPanel panel; // allows to write to the panel

public BTServer(){

try {
LocalDevice local =LocalDevice.getLocalDevice();

local.setDiscoverable(DiscoveryAgent.GIAC);

}catch (BluetoothStateException e){

}

setUpServer();
}

// sets up the sever
public void setUpServer(){

// Define the server connection URL
String connection = "btspp://localhost:"+serviceUUID+";name="+serviceName;

try{

// server connection
// also registers the service record in database
StreamConnectionNotifier notifier = (StreamConnectionNotifier) Connector.open(connection, Connector.READ_WRITE);

StreamConnection client = notifier.acceptAndOpen();

// handle client
RemoteDevice rd = RemoteDevice.getRemoteDevice(client);

DataInputStream in = client.openDataInputStream();

String recived = in.readUTF();

System.out.println(recived);

recived = in.readUTF();

System.out.println(recived);

// panel.addToPanel(recived);
in.close();


}catch(IOException io){
}
}

}


The following is running on the pc (client). (it works fine on the phone as a client). I use the
xp bluetooth stack


public class BTClient{


public static void main(String [] args){
BTClient{b = new BTClient{
}

protected LocalDevice local = null;
protected DiscoveryAgent agent = null;
protected DeviceListener listener;

public BTServer(){
doDeviceDiscovery();
}


// searche for local devices
public void doDeviceDiscovery() {
try {

local = LocalDevice.getLocalDevice();

}catch (BluetoothStateException bse) {

System.out.println("error");
}

agent = local.getDiscoveryAgent();

try {
// the device listner has the device listenrs in
listener = new DeviceListener();

if(!agent.startInquiry(DiscoveryAgent.GIAC,listener)) {
// System.out.println("Inquiry not started");
System.out.println("erro 1");
}

}catch(BluetoothStateException bse) {
//System.out.println("BluetoothStateException " + bse.getMessage());
System.out.println("erro r3");
}
}

// The device and service listern
class DeviceListener implements DiscoveryListener{

protected Vector list = new Vector(); // holds the devices found in the search

public void deviceDiscovered(RemoteDevice remoteDevice, DeviceClass deviceClass) {

list.addElement(remoteDevice);
}

// the inquiry has completed
public void inquiryCompleted(int param) {

switch (param) {
case DiscoveryListener.INQUIRY_COMPLETED:

for(int i=0; i<list.size(); i++){

// remote device
RemoteDevice rd = (RemoteDevice)list.elementAt(i);


// found server, hardcoded the server phone bluetooth adress
if(rd.getBluetoothAddress().equals("000e6d51b034")){


// the uuid is the same as the one in the server
UUID [] uuid = new UUID[1];

uuid[0] = new UUID("2d26618601fb47c28d9f10b8ec891363",false);

try{

// *CARRY OUT A SERVICE SEARCH ON THE REMOTE DEVICE (E.G IF
// BLUETOOTH ADDRESS IS 000e6d51b034 I.E. THE SERVER)
// *
// * AS A RESULT THERE WILL ONLY BE ONE SERVICE FOUND IN
// * THE SERVICEDISCOVERED METHOD
// *


agent.searchServices(null,uuid,rd,this);

}catch(BluetoothStateException bse){
// Calender.numberFound.setText("Error when search began");
System.out.println("error 3");
}

}
}

break;

case DiscoveryListener.INQUIRY_ERROR:
// System.out.println("Inquiry error");
// synMemo.setText("inquiry error");
System.out.println("error");
break;

case DiscoveryListener.INQUIRY_TERMINATED:
// System.out.println("Inquity completed");
System.out.println("error");
break;
}
}

public void servicesDiscovered(int transID,ServiceRecord[] serviceRecord) {

/*
IS THE PROBLEM HERE? , HOWEVER I AM SEARCHING WITH THE UUID, THERE SAME AS THE ONE IN THE SERVER
*/


ServiceRecord sr = (ServiceRecord)serviceRecord[transID];


String connURL = sr.getConnectionURL(ServiceRecord.NOAUTHENTICATE_NOENCRYPT, false);

try{
StreamConnection sc = (StreamConnection) Connector.open(connURL);

DataOutputStream out = sc.openDataOutputStream();

out.writeUTF("end");
System.out.println("written");

out.close();

}catch(IOException io){
// synMemo.setText("ioerror");
System.out.println("IO ERROR, MAIN");
}


}

public void serviceSearchCompleted(int transID, int respCode) {
}

}






tHATS IT, THE FUNNY think is that the above code fully excutes e.g. outputs end!

Its just the server on the phone doesnt "StreamConnection client = notifier.acceptAndOpen();"

But no erroe are thrown,

Any help will be great.

Thanks alot

how do u know no errors are thrown?
look at your server code..
"try{

// server connection
// also registers the service record in database
StreamConnectionNotifier notifier = (StreamConnectionNotifier) Connector.open(connection, Connector.READ_WRITE);

StreamConnection client = notifier.acceptAndOpen();

// handle client
RemoteDevice rd = RemoteDevice.getRemoteDevice(client);

DataInputStream in = client.openDataInputStream();

String recived = in.readUTF();

System.out.println(recived);

recived = in.readUTF();

System.out.println(recived);

// panel.addToPanel(recived);
in.close();


}catch(IOException io){
}"

the catch is empty and since its not the phone that u are running the server you wont see any stack trace or the app wont close since its in try/catch block

so place some debug msgs there and only then you can say whats realy going on..

hello, i have alread done that, i removes all output statemensts to reduce the amount of code,

why would there be a prblem when switching the code over?

[shaii]

have you done somthing in the catch clause???
if so print that exception msg to the screen and write it here...

[ug94bxs]

hey, its ok i sorted it out. the connection url was wrong
