外围设备不与Central通信

Question

我正在尝试通过蓝牙低功耗进行通信，我们的CBCentralManager实现已在Objective-C中完成，但我正在尝试通过Swift实现CBPeripheral。

我无法建立连接。这就是我在CBPeripheral实施中做广告的方式：

public func initialize() 
    {
        let queue =  dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)
        perpheralManager = CBPeripheralManager(delegate: self, queue: queue)
        startConnecting()
    }



public func peripheralManagerDidUpdateState(peripheral: CBPeripheralManager)
     {
        switch peripheral.state
        {
        case CBPeripheralManagerState.PoweredOn:
            setUpServices()
            break
        default:break

        }
    }

private func setUpServices()
    {

        self.slideIndexCharacterestics = CBMutableCharacteristic(type: CBUUID(string: UUID.transferSlideIndex), properties: [CBCharacteristicProperties.Read,CBCharacteristicProperties.NotifyEncryptionRequired],
            value: nil, permissions: CBAttributePermissions.ReadEncryptionRequired)

        let services = CBMutableService(type: CBUUID(string: UUID.transferService), primary: true)
        services.characteristics = [self.slideIndexCharacterestics!]
        self.perpheralManager!.addService(services)
    }
 public func peripheralManager(peripheral: CBPeripheralManager, didAddService service: CBService, error: NSError?)

    {
        startConnecting()
    }


func startConnecting()
{
    let adData = [CBAdvertisementDataServiceUUIDsKey:CBUUID(string:"D6087B90-F460-4BE1-A9C8-E1CD8E7858E9")]
    self.perpheralManager!.stopAdvertising()
    self.perpheralManager!.startAdvertising(adData)
}

注意：如果我在Objective-C两端实现，我能够成功通信。
