示例1: socketProtocol
/*!
Returns the protocol that the QBluetoothServiceInfo object uses.
*/
QBluetoothServiceInfo::Protocol QBluetoothServiceInfo::socketProtocol() const
{
QBluetoothServiceInfo::Sequence parameters = protocolDescriptor(QBluetoothUuid::Rfcomm);
if (!parameters.isEmpty())
return RfcommProtocol;
parameters = protocolDescriptor(QBluetoothUuid::L2cap);
if (!parameters.isEmpty())
return L2capProtocol;
return UnknownProtocol;
}示例2: protocolServiceMultiplexer
/*!
This is a convenience function. Returns the protocol/service multiplexer for services which
support the L2CAP protocol, otherwise returns -1.
This function is equivalent to extracting the information from
QBluetoothServiceInfo::Sequence returned by
QBluetoothServiceInfo::attribute(QBluetoothServiceInfo::ProtocolDescriptorList).
*/
int QBluetoothServiceInfo::protocolServiceMultiplexer() const
{
QBluetoothServiceInfo::Sequence parameters = protocolDescriptor(QBluetoothUuid::L2cap);
if (parameters.isEmpty())
return -1;
else if (parameters.count() == 1)
return 0;
