Question

我正在实施一个使用蓝牙连接到Raspberry Pi的OS X应用程序。问题是应用程序无法发现RPI，而我可以在Mac的本机蓝牙面板上看到它。该应用程序仅发现一个具有＆＃34; null＆＃34;名称（我在Mac的蓝牙面板上看到的每个设备都有一个名字）。

对问题可能是什么有任何想法？

以下是我的蓝牙管理器单例的实现：

static let sharedInstance = KNKBluetoothManager()

var centralManager : CBCentralManager!
var remotePeripheral : CBPeripheral?
var bluetoothReady = false

func startUpCentralManager()
{
    print("Initializing central manager")
    centralManager = CBCentralManager(delegate: self, queue: nil)
}

func discoverDevices()
{
    print("discovering devices")
    centralManager.scanForPeripheralsWithServices(nil, options: nil)
}

func centralManager(central: CBCentralManager, didDiscoverPeripheral peripheral: CBPeripheral, advertisementData: [String : AnyObject], RSSI: NSNumber)
{
    print("Discovered \(peripheral)")

    if (peripheral.name == "rpi")
    {
        self.remotePeripheral = peripheral
        self.centralManager.stopScan()
        self.remotePeripheral?.delegate = self
        centralManager.connectPeripheral(peripheral, options: nil)
    }
}

func centralManagerDidUpdateState(central: CBCentralManager)
{
    print("checking state")
    switch (central.state)
    {
    case .PoweredOff:
        print("CoreBluetooth BLE hardware is powered off")
        bluetoothReady = false

    case .PoweredOn:
        print("CoreBluetooth BLE hardware is powered on and ready")
        bluetoothReady = true;

    case .Resetting:
        print("CoreBluetooth BLE hardware is resetting")

    case .Unauthorized:
        print("CoreBluetooth BLE state is unauthorized")

    case .Unknown:
        print("CoreBluetooth BLE state is unknown");

    case .Unsupported:
        print("CoreBluetooth BLE hardware is unsupported on this platform");

    }
    if bluetoothReady
    {
        discoverDevices()
    }
}

didDiscoverPeripheral方法总是找到相同的外围设备：

Discovered <CBPeripheral: 0x6080000aada0 identifier = 36844111-01E4-4D00-926B-AAF089C04305, Name = "(null)", state = disconnected>

很好地指出我在iOS应用程序（使用iPhone 5）上使用相同的实现时遇到了完全相同的问题。

CoreBluetooth：只发现一个外设，而原生蓝牙功能发现三个
