Detailed Description
The QL2capServer class allows you to connect to a service using the L2CAP protocol.
QL2capServer is used to implement Bluetooth services over L2CAP.
Start listening for incoming connections with listen(). Wait till the newConnection() signal is emitted when the connection is established, and call nextPendingConnection() to get a QBluetoothSocket for the connection.
To enable other devices to find your service, create a QBluetoothServiceInfo with the applicable attributes for your service and register it using QBluetoothServiceInfo::registerService(). Call serverPort() to get the L2CAP port number that is being used.
Member Function Documentation
QL2capServer::QL2capServer(QObject * parent = 0)
Constructs an L2CAP server with parent.
QL2capServer::~QL2capServer()
Destroys the L2CAP server.
void QL2capServer::close()
Closes and resets the listening socket.
bool QL2capServer::hasPendingConnections() const
Returns true if a connection is pending, otherwise false.
bool QL2capServer::isListening() const
Returns true if the L2CAP server is listening for incoming connections, otherwise false.
bool QL2capServer::listen(const QBluetoothAddress & address = QBluetoothAddress(), quint16 port = 0)
Start listening for incoming connections to address on port.
Returns true if the operation succeeded and the L2CAP server is listening for incoming connections, otherwise returns false.
See also isListening() and newConnection().
int QL2capServer::maxPendingConnections() const
Returns the maximum number of pending connections.
See also setMaxPendingConnections().
void QL2capServer::newConnection() [signal]
This signal is emitted when a new connection is available.
The connected slot should call nextPendingConnection() to get a QBluetoothSocket object to send and receive data over the connection.
See also nextPendingConnection() and hasPendingConnections().
QBluetoothSocket * QL2capServer::nextPendingConnection()
Returns a pointer to a QBluetoothSocket for the next pending connection. It is the callers responsibility to delete the pointer.
Returns the Bluetooth security flags.
See also setSecurityFlags().
QBluetoothAddress QL2capServer::serverAddress() const
Returns the server address.
quint16 QL2capServer::serverPort() const
Returns the server port number.
void QL2capServer::setMaxPendingConnections(int numConnections)
Sets the maximum number of pending connections to numConnections.
See also maxPendingConnections().
Sets the Bluetooth security flags to security. This function must be called before calling listen().
See also securityFlags().
