CoreBluetooth didDiscoverPeripheral在Swift中没有被调用

Question

我99%确定我按照说明正确设置了CoreBluetooth。无论我做什么，当我在我的iPad mini上运行这个应用程序时，蓝牙都会显示它是开启的。它说它正在扫描设备，但它绝对没有找到任何设备。如果我转到设备上的蓝牙菜单，我确实看到正在发现其他设备。我初始化CBCentralManager。设置centralManagerDidUpdateState。当确定蓝牙准备就绪时，它调用centralManager.scanForPeripheralsWithServices。这一切都是正确的。但是我的委托函数centralManager(central: CBCentralManager!, didDiscoverPeripheral peripheral: CBPeripheral!, advertisementData: [NSObject : AnyObject]!, RSSI: NSNumber!)永远不会被调用。我的代码非常简单。也许我遗漏了什么，但我能够确认我的Macbook是一个BTLE设备，我的ipad mini也是一个BTLE设备。这是我的代码。

import UIKit
import CoreBluetooth
class ViewController: UIViewController, CBCentralManagerDelegate {
    var centralManager:CBCentralManager!
    var blueToothReady = false
    override func viewDidLoad() {
        super.viewDidLoad()
        startUpCentralManager()
    }
    func startUpCentralManager() {
        println("Initializing central manager")
        centralManager = CBCentralManager(delegate: self, queue: nil)
    }
    func discoverDevices() {
        println("discovering devices")
        centralManager.scanForPeripheralsWithServices(nil, options: nil)
    }
    func centralManager(central: CBCentralManager!, didDiscoverPeripheral peripheral: CBPeripheral!, advertisementData: [NSObject : AnyObject]!, RSSI: NSNumber!) {
        println("Discovered (peripheral.name)")
    }
    func centralManagerDidUpdateState(central: CBCentralManager!) {
        println("checking state")
        switch (central.state) {
            case .PoweredOff:
            println("CoreBluetooth BLE hardware is powered off")
            case .PoweredOn:
            println("CoreBluetooth BLE hardware is powered on and ready")
            blueToothReady = true;
            case .Resetting:
            println("CoreBluetooth BLE hardware is resetting")
            case .Unauthorized:
            println("CoreBluetooth BLE state is unauthorized")
            case .Unknown:
            println("CoreBluetooth BLE state is unknown");
            case .Unsupported:
            println("CoreBluetooth BLE hardware is unsupported on this platform");
        }
        if blueToothReady {
            discoverDevices()
        }
    }
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
}

我得给我的macbook做广告。一旦我使用https://github.com/mttrb/BeaconOSX这样做了，它就完全像我写的那样工作了。
