CoreBluetooth：无法findiPad

我不知道如何使用CoreBluetooth ，我试图find我的iPad，并从该iPad获取GPS，加速计，陀螺仪的信息（不要问为什么）。 我知道如何获得GPS位置，但我不知道如何获得加速度计和陀螺仪。 Plz帮助我。 应用程序必须快速。

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

好吧，我做了LighBlue应用程序的虚拟外设，这个代码的作品：

  // // ViewController.swift // BLE // // Created by Tomasz Kaczmarzyk on 01.09.2014. // Copyright (c) 2014 Tomasz Kaczmarzyk.

[CBService] { for servicePeripheral in servicePeripherals { servicesBLE.text = "Services: \(servicePeripheral)" println(servicePeripheral) peripheral.discoverCharacteristics(nil, forService: servicePeripheral) } } } @IBAction func refreshBLE(sender: UIButton) { centralManager.scanForPeripheralsWithServices(nil, options: nil) } func peripheral(peripheral: CBPeripheral!, didDiscoverCharacteristicsForService service: CBService!, error: NSError!) { if let charactericsx = service.characteristics as? [CBCharacteristic] { for charactericsx in charactericsx { //servicesBLE.text = "Characterics: \(charactericsx)" println(charactericsx) peripheral.readValueForCharacteristic(charactericsx) } } } func peripheral(peripheral: CBPeripheral!, didUpdateValueForCharacteristic characteristic: CBCharacteristic!, error: NSError!) { var data :NSData = characteristic.value println("Data \(characteristic.value)") } } 

此代码适用于LightBlue应用程序，并从CoreBluetooth Objective C编程指南转换而来。
