Add SDP service record

Hi all,

I want to add a my own SPP to the SDP record, but I don't know why it is not success. I have read through some and the UIQ documentation, but still can't find the solution. Could anyone tell me what I have done wrong? Following is my code,

// 1. Create and open session to the database
//RSdp sdp;
User::LeaveIfError(sdp.Connect());

// 2. Create and open a subsession
//RSdpDatabase sdpSubSession;
User::LeaveIfError(sdpSubSession.Open(sdp));
   
// Assumes sdpSession is an open session to the database
// 1. Create blank record handle
recordHandle = 0;

// 2. Create the service class UUIDs
TUUID uuid(0x1101);

// 3. Enter record into the database
sdpSubSession.CreateServiceRecordL(uuid, recordHandle);

// Assumes sdpSubSession is an open subsession to the database,
// and recordHandle is the service record

_LIT8(KProvName,"Vincent SPP.");
CSdpAttrValueString* attrVal = CSdpAttrValueString::NewStringL(KProvName);
CleanupStack::PushL(attrVal);
sdpSubSession.UpdateAttributeL(recordHandle, 0x0102, *attrVal);
CleanupStack::PopAndDestroy();

Thank you very much for any help!

Thanks,
Vincent
