发现后iOS周边服务还是空的

Question

我正在尝试使用蓝牙我有这样的东西:

func centralManager(central: CBCentralManager, didConnectPeripheral peripheral: CBPeripheral) {
    Connected = true
    TableView.reloadData()
    Activityview.stopAnimating()
    TabBar.topItem!.rightBarButtonItem = UIBarButtonItem(title: "Suivant", style: UIBarButtonItemStyle.Done, target: nil, action: #selector(Connexion.next))
    CM.stopScan()
    Scanning = false
    Refresh_Button.setTitle("Deconnecté", forState: UIControlState.Normal)
    let AlertMessage = UIAlertController(title: "Connecté", message: "Le module est bien connecté", preferredStyle: .Alert)
    let ActionAlert = UIAlertAction(title: "Ok", style: .Default) { (action) in }
    AlertMessage.addAction(ActionAlert)
    self.presentViewController(AlertMessage, animated: true, completion: nil)
    peripheral.delegate = self
    let servicetoFind = CBUUID(string: "19B10000-E8F2-537E-4F6C-D104768A1214")
    peripheral.discoverServices([servicetoFind])
}

我的服务功能:

func peripheral(peripheral: CBPeripheral, didDiscoverServices error: NSError?) {
    print("found service")
    print(peripheral)
    print(peripheral.services)
    print(error)
    for service in peripheral.services! {
        print("Searching for charac...")
        peripheral.discoverCharacteristics(nil, forService: service)
    }
}

找到我的服务并进入控制台:

found service
<CBPeripheral: 0x13ce1c430, identifier = F39F9D5D-98FE-A350-17BD-21C1185E2089, name = GENUINO 101-1E2D, state = connected>
Optional([])
nil

为什么我的外设服务发现后还是空的，但没有报错？

有什么想法吗？

谢谢!
