      Hi all,

      Scanning for BLE devices on MacOs seems to have issues! I detect classic bluetooth devices along with LE devices.

      I am using the following code to scan:

      self.__discovery_agent: QBluetoothDeviceDiscoveryAgent = QBluetoothDeviceDiscoveryAgent()
self._discovery_agent.deviceDiscovered.connect(self._discovery_agent_device_discovered_handler)
self._discovery_agent.finished.connect(self._discovery_agent_scan_finished_handler)
self.__discovery_agent.DiscoveryMethod = QBluetoothDeviceDiscoveryAgent.LowEnergyMethod
self.__discovery_agent.setLowEnergyDiscoveryTimeout(timeout)
self.__discovery_agent.start()

      I have an assumption that the following line of code should limit the scanning to BLE devices:

      self.__discovery_agent.DiscoveryMethod = QBluetoothDeviceDiscoveryAgent.LowEnergyMethod 

      This code works pretty fine on WindowsOS.

      I see the following traces during scanning phase:

      Please note that I've communicated with Qt C++ devs. and they replied that 
      a C++-based code on MacOS does not detect classic bluetooth devices.
