Hello, I have big problem with my JAVA code on real 6230 phone. My code looks:

LocalDevice localdevice = LocalDevice.getLocalDevice();
discoveryAgent = localdevice.getDiscoveryAgent();

Here I am getting NullPointerException and I can't use JSR 82 on this mobile.

I have also real N6600 and on this mobile, everything is working perfectly.

Can someone help me???

Hello,

Nokia 6230 does not have JSR-82 support.

Whereas Nokia 6600 does have the support.

Hence the case.


regards,

Nokia 6230 DOES support JSR-82. Have you looked at the existing Bluetooth examples?

The following two documents both include a Java MIDP example:
-Introduction to Developing Networked MIDlets using Bluetooth
-Games over Bluetooth: Recommendations to Games Developers

You can download these pakcages from the Bluetooth -> Documents section at Forum Nokia:

I looked there, I try to install the sample application - bluetooth chat on 6230, but it's the same as in my program - NullPointerException, on 6600 it's working well. I don't understand why...

Maybe you have an old frimware version on your phone. I had similar problem with
the bluetooth implemenrtation on old friware version.

That's interesting, so I need to update firmware? I was looking to Nokia Website, but I didn't found any information, where to download the new firmware. On internet I found something, but I think, it's quite risky to install not official firmware, can you post, how to download and install the new firmware?
(Maybe my question is stupid, but on Nokia site, I really found nothing.)

I had this problem too. Easily solved by turning on Bluetooth (Menu->settings->connectivity->bluetooth).

Do this and then run your Midlet.

I have the same problem, but i didn't test it with a 6600 because I haven't one. If you know what's the solution, please: bombas666@gmail.com

This is my code and it works on a 6230i bought in 2005.

-------------------------------------------------------
// jsr082 API
import javax.bluetooth.BluetoothStateException;
import javax.bluetooth.DataElement;
import javax.bluetooth.DeviceClass;
import javax.bluetooth.DiscoveryAgent;
import javax.bluetooth.DiscoveryListener;
import javax.bluetooth.LocalDevice;
import javax.bluetooth.RemoteDevice;
import javax.bluetooth.ServiceRecord;
import javax.bluetooth.UUID;

LocalDevice local=null;
DiscoveryAgent agent=null;
Vector deviceVector = null;


try {

local = LocalDevice.getLocalDevice();

}catch(BluetoothStateException bse) {

a = new Alert("Bluetooth error","Bluetooth must be turned on");
a.setTimeout(Alert.FOREVER);
a.addCommand(exitCommand);
a.setCommandListener(this);

}

try {

agent = local.getDiscoveryAgent();
}

catch (Exception e) {
a = new Alert(("Can't initialize bluetooth: " + e);
a.setTimeout(Alert.FOREVER);
a.addCommand(exitCommand);
a.setCommandListener(this);

}

deviceVector = new Vector();

RemoteDevice[] devices = agent.retrieveDevices(DiscoveryAgent.PREKNOWN);
if (devices == null) {
devices = agent.retrieveDevices(DiscoveryAgent.CACHED);

}
-----------------------------------------------------------

The code to Display Alert is off topic.

My main addition I found is exception trapping. Which seems to work.

Are you 6230 with the 'i' in which case early bluetooth device need a firmware upgrade.
