无法通过Core蓝牙(MacOS Swift)发现蓝牙鼠标和键盘

我对使用corebuttle框架的设备有问题。基本上,我需要在OSX中复制标准蓝牙发现应用程序的功能,所以我做了以下操作:

let bluetoothManager = CBCentralManager()

//Lifecycle

 override func viewDidLoad() {
    super.viewDidLoad()
    bluetoothManager.delegate = self
}

//delegate method

func centralManagerDidUpdateState(_ central: CBCentralManager) {
    switch central.state {
    case .poweredOn:
        print("powered on")
        central.scanForPeripherals(withServices: nil, options: nil)
    case .unknown:
        print("state unknown")
    case .resetting:
        print("resetting")
    case .unsupported:
        print("unsupported")
    case .unauthorized:
        print("unauthorized")
    case .poweredOff:
        print("powered off")
    }
}

现在我只是把外设打印到控制台上:

func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber) {
    print("discovered some perilherials", peripheral)    
}

我搜索了 bluetooth.com 规格,但没有运气

任何建议都很好!
