使用 PyQt6 连接到 MAC 地址

Question

I would like to connect to a MAC address ( of a BLE dongle ) with PyQt or PySide. I know that I need to create a controller and a mac address object but somehow it does not work.

def connect_to_mac(self, mac_address: str):
    self.current_device = QtBluetooth.QBluetoothDeviceInfo()
    self.controller = QtBluetooth.QLowEnergyController.createCentral(self.current_device)
    QtBluetooth.QBluetoothAddress(mac_address)
    address_type = QtBluetooth.QLowEnergyController.RemoteAddressType.PublicAddress
    self.controller.setRemoteAddressType(address_type)
    self.controller.connectToDevice()

Answer 1

Do things in the right order. First, convert your mac address to a QBluetoothAddress . Then, pass that to QBluetoothDeviceInfo to create a device info structure. Then, pass that to createCentral and connect to the device.

I have not tried this, but this should be the right sequence:

def connect_to_mac(self, mac_address: str):
    addr = QtBluetooth.QBluetoothAddress(mac_address)
    device = QtBluetooth.QBluetoothDeviceInfo(addr)
    self.controller = QtBluetooth.QLowEnergyController.createCentral(device)
    self.controller.connectToDevice()
