Hello dear all,

I am developing the project using Bluetooth connections in sdk 3FP2.
because The Bluetooth Engine API provides high-level access to Bluetooth settings and device management. There is a compatibility break in the Bluetooth Engine API between S60 3rd Edition, Feature Pack 1 and Feature Pack 2.
so when I install the old version(3.0\3.1) Bluetooth Engine to new version(3FP2). it can not establish the connections. when set the RSocket::Accept() functions to setActive(), but can not call the RunL() to implement the state change:
following is the code:
//////////////////////////////////////////////
CBTENGINE::ConnectL()
{
if (iState != EDisconnected)
{
TRACE("iState is not EDisconnected");
User::Leave(KErrInUse);
}

User::LeaveIfError(iSocketServer.Connect());
User::LeaveIfError(iListeningSocket.Open(iSocketServer, KServerTransportName));

// Get a channel to listen on - same as the socket's port number
User::LeaveIfError(iListeningSocket.GetOpt(KRFCOMMGetAvailableServerChannel, KSolBtRFCOMM, iChannel));

TBTSockAddr listeningAddress;
listeningAddress.SetPort(iChannel);

User::LeaveIfError(iListeningSocket.Bind(listeningAddress));
User::LeaveIfError(iListeningSocket.Listen(KListeningQueSize));

/////////
iAcceptedSocket.Close(); // close old connection - if any
User::LeaveIfError(iAcceptedSocket.Open(iSocketServer)); // Open abstract socket

iState = EConnecting;

// set the listening socket to accept new connections on
// the accepted socket.


iListeningSocket.Accept(iAcceptedSocket, iStatus);
SetActive();
}
/////////////////////////////////////////////
CBTENGINE::RunL()
{
case EConnecting:
{
// do not accept any more connections
iAdvertiser->StopAdvertisingL();
iState = EConnected;
break;
}
}


when the code run to the iListeningSocket.Accept(iAcceptedSocket, iStatus);
SetActive(); to wait for the connect. but there are no response when phones connect each other.
so the RunL() function can not work.

any one can help me??

This is known that there is a break between 3.1 & 3.2

mahbub,I am facing the same problem as landerlu.I read the document about the break from 3.2.I found this sentence."For applications using Bluetooth Engine API, this change causes both binary and source compatibility breaks between those platform versions. "
But we don't use Bluetooth Engine API in our application,so in the platform of 3.2,application can be built successfully

Hi,
You can try this example, this should work platform independent way here is the link
