S603rd BluetoothPMPExample - does not work after changes

[Zdenko61]

Hi all,

I have followed instruction
Debugging Symbian S60 with Carbide C++ Express and NCF 1.2 Bluetooth
http://discussion.forum.nokia.com/fo...ad.php?t=88537

and I modified CListener::SetSecurityL
void CListener::SetSecurityL(TInt aChannel)
{
TRequestStatus status;
RBTMan secManager;
TBTServiceSecurity secSettings;
TBTSockAddr listeningAddress;
// Set the Port to listen to.
listeningAddress.SetPort( aChannel );
// setup security
TUid settingsUID;
settingsUID.iUid = KBT_serviceID;
secSettings.SetUid(settingsUID);
secSettings.SetAuthentication(EFalse);
secSettings.SetAuthorisation(EFalse);
secSettings.SetEncryption(EFalse);
secSettings.SetDenied(EFalse);
// register settings with security
// Attach the security settings.
listeningAddress.SetSecurity(secSettings);
}
but example app does not work.

If I select "Discover devices" I got "Unable to execute file for security reason"
I added "NetworkServices" and "ReadUserdata" capabilities.

Most interesting that if I select "Start Slave" application crashes without any error message.

What capabilities requires TBTServiceSecurity?
What causes application to crash?

Hi, use the following cabs:
CAPABILITY LocalServices UserEnvironment ReadUserData WriteUserData NetworkServices

Change the following:
void CListener::StartListenerL(TInt& aChannel)
{
// get out if we're already running..
if ( iState!=ENone )
{
User::Leave(KErrInUse);
}

// set this active object to connecting state
iState=EConnecting;

// load protocol, RFCOMM
TProtocolDesc pdesc;
User::LeaveIfError(iSocketServ.FindProtocol(KRfComm(), pdesc));

// open a socket
User::LeaveIfError(
iListenSock.Open(iSocketServ,
pdesc.iAddrFamily,pdesc.iSockType,KRFCOMM)
);

// get listening channel
User::LeaveIfError(iListenSock.GetOpt(KRFCOMMGetAvailableServerChannel,
KSolBtRFCOMM, aChannel));

// bluetooth socket address object
TBTSockAddr btsockaddr;
btsockaddr.SetPort(aChannel);
// bind socket
User::LeaveIfError(iListenSock.Bind(btsockaddr));
// listen on port
iListenSock.Listen(KSizeOfListenQueue);

//now set security

//old way to set security is in Listener.cpp
//CListener::SetSecurityL(TInt aChannel)
TBTServiceSecurity secSettings;

TUid settingsUID;
settingsUID.iUid = KBT_serviceID;
secSettings.SetUid(settingsUID);
//the old way involved the following two steps:
//secSettings.SetChannelID(aChannel);
//secSettings.SetProtocolID(KSolBtRFCOMM);
secSettings.SetAuthentication(EFalse);
secSettings.SetAuthorisation(EFalse);
secSettings.SetEncryption(EFalse);

// attach the security settings.
btsockaddr.SetSecurity(secSettings);

// close old accepted socket if open
iSock.Close();

// open blank socket and pass it to accept to be assigned a proper
// socket upon completion of Accept()
User::LeaveIfError(iSock.Open(iSocketServ));

// set to accept incoming connections, active object will handle
iListenSock.Accept(iSock,iStatus);
SetActive();
}

Works for me. There will be an updated version soon of BT PMP example which will support 3rd edition.

thanks so much pkosonen, for that reply, i wanted to ask you why the bluetoothpmpexample doest create the sys file when i compile it?

It's the same project that is on the nokia website

i am using s60 3d edition

thanks for any tip

[wizard_hu_]

In what environment do you compile it, and how?

Hi, thanks for the reply, i am working on carbide c/c++, i did the change that pkosonen told me and i still have the same error, it says "Unable to execute file, for security reasons"

And what pkosonen means with
"Hi, use the following cabs:
CAPABILITY LocalServices UserEnvironment ReadUserData WriteUserData NetworkServices"

Any thoughts?

Thanks so much

if it is necesarry i have this two methods

void CListener::StartListenerL(TInt& aChannel)
{
// get out if we're already running..
if ( iState!=ENone )
{
User::Leave(KErrInUse);
}

// set this active object to connecting state
iState=EConnecting;

// load protocol, RFCOMM
TProtocolDesc pdesc;
User::LeaveIfError(iSocketServ.FindProtocol(KRfComm(), pdesc));

// open a socket
User::LeaveIfError(
iListenSock.Open(iSocketServ,
pdesc.iAddrFamily,pdesc.iSockType,KRFCOMM)
);

// get listening channel
User::LeaveIfError(iListenSock.GetOpt(KRFCOMMGetAvailableServerChannel,
KSolBtRFCOMM, aChannel));

// bluetooth socket address object
TBTSockAddr btsockaddr;
btsockaddr.SetPort(aChannel);
// bind socket
User::LeaveIfError(iListenSock.Bind(btsockaddr));
// listen on port
iListenSock.Listen(KSizeOfListenQueue);

//now set security

//old way to set security is in Listener.cpp
//CListener::SetSecurityL(TInt aChannel)
TBTServiceSecurity secSettings;

TUid settingsUID;
settingsUID.iUid = KBT_serviceID;
secSettings.SetUid(settingsUID);
//the old way involved the following two steps:
//secSettings.SetChannelID(aChannel);
//secSettings.SetProtocolID(KSolBtRFCOMM);
secSettings.SetAuthentication(EFalse);
secSettings.SetAuthorisation(EFalse);
secSettings.SetEncryption(EFalse);

// attach the security settings.
btsockaddr.SetSecurity(secSettings);

// close old accepted socket if open
iSock.Close();

// open blank socket and pass it to accept to be assigned a proper
// socket upon completion of Accept()
User::LeaveIfError(iSock.Open(iSocketServ));

// set to accept incoming connections, active object will handle
iListenSock.Accept(iSock,iStatus);
SetActive();

}


// ----------------------------------------------------------------------------
// CListener::SetSecurityL(TInt aChannel)
//
// sets the security of given bluetooth channel. these settings will turn
// off authentication, authorisation and encryption on given channel.
// ----------------------------------------------------------------------------
void CListener::SetSecurityL(TInt aChannel)
{

// setup channel security
TRequestStatus status;
RBTMan secManager;

RBTSecuritySettings secDatabase;
TBTServiceSecurity secSettings;
// connect to security manager
User::LeaveIfError(secManager.Connect());
CleanupClosePushL(secManager);
User::LeaveIfError(secDatabase.Open(secManager));
CleanupClosePushL(secDatabase);
// setup security
TUid settingsUID;
settingsUID.iUid = KBT_serviceID;
secSettings.SetUid(settingsUID);
secSettings.SetChannelID(aChannel);
secSettings.SetProtocolID(KSolBtRFCOMM);
secSettings.SetAuthentication(EFalse);
secSettings.SetAuthorisation(EFalse);
secSettings.SetEncryption(EFalse);
// register settings with security
secDatabase.RegisterService(secSettings, status);
User::WaitForRequest(status);
CleanupStack::PopAndDestroy(2,&secManager);//SecDatabase, secManager

}

I am not sure if anyone has tested this example with NCF... Also note that now it is 2008, and the most recent BTPMP example has just been released 1-2 months ago. Pkosonen's suggestions from 2006 might not be really valid for it.
However I am not sure about your security warning, since it should not appear (the CAPABILITY line is already present in the .mmp file - if it is not, you might have picked a wrong .mmp).
