Hi all,

I have a problem with attribute in bluetooth, here is my code:

try {
device = LocalDevice.getLocalDevice();
device.setDiscoverable(DiscoveryAgent.GIAC);

String url2 = "btspp://localhost:"
+ uuid2.toString()
+";authorize=true;authenticate=false;encrypt=false"
+ ";name="
+ appName;

server = (StreamConnectionNotifier) Connector.open(url2);


ServiceRecord rec = device.getRecord(server);

DataElement elm = null;
elm = new DataElement(DataElement.STRING,"BT Server");
if(rec.setAttributeValue(0x101,elm))
log("101 added");

/* Set service provider name */
elm = new DataElement(
DataElement.STRING,"CINI, Research Group");
if(rec.setAttributeValue(0x102,elm))
log("102 added");
// rec.setDeviceServiceClasses(SERVICE_TELEPHONY);
device.updateRecord(rec);
c = server.acceptAndOpen();
}
Server should add these attributes: 258,257,256,4,1

Client:

DataElement dataelem = null;
String name = null;
for ( int i=0; i< records.length; i ++ )
{

ServiceRecord record = records[i];
int IDs2[] = record.getAttributeIDs();
for (int j=0;j<IDs2.length;j++){
DataElement prova = record.getAttributeValue(IDs2[j]);
System.out.println(IDs2[j]+" "+prova.getDataType());
if(prova.getDataType()==DataElement.STRING)
System.out.println(prova.getValue().toString());
}
services.addElement( record );
}
}

Client retrieves only these attribute: 0,1,4

where is the problem?
My code has been copied from other working code.
I use nokia 9500 but also nokia 6680 and it does not work the same.

please help me :-(

Hello.
Could you please talk about the solution? I have the same problem, but only when I build with NetBeans 5.0 (building with WTK attributes are correctly published).
Thanks.

If you are using BluecoveXP the Service Record will not support extra attributes.

Only UUID = {0x0000,0x0001,0x0004,0x0100);
You can recompile BlueCove to add attributes,which works,but obviously its unique, and not dynamic and non standard.


The Mobility toolkit will support more but obviously this does not connect with the real world! as its an emulator.

I have not use NB 5.1 and Netbeans 5.1 mobility, but NB 5.0 beta did NOT work, so updgrading to 5.1 and Netbeans 5.1 Mobility might be the answer. It works in Nb 4.1

Thanx Jim.
My problem with custom service attributes in midlets was that I was not fetching them at service discovery. I solved it simply adding my custom attribute numbers in the array passed to DiscoveryAgent.searchServices function as first parameter. It was not a problem of NetBeans :$

About Bluecove, I could see that UpdateRecord function is not available with this library, so it does not allow for custom service attributes. I'll try to achieve this using Avetana with Bluez in a Linux Server instead.

Glad you has success.

Yes this is true. I dont have a problem as Avetana cannot currently update services either, you may have more luck on Bluez because you do not have to work with XP internals for bluetooth.
