无法通过BLE连接到AirPods [英] Can't connect to AirPods via BLE

问题描述

我正在尝试使用BLE使用一个简单的应用程序自动连接到我的AirPods.我得到了设备的名称和状态为正在连接"，但是由于某种原因我无法连接到它.永远不会触发功能"didConnect外设".

I am trying to connect automatically to my AirPods with a simple app using BLE. I get the name of the device and the status to "connecting", but for some reason I can't connect to it. Function 'didConnect peripheral' is never triggered.

我尝试了教程和其他文章中提出的所有不同方法，试图将外围数据存储在数组中以保留引用，但似乎无济于事.

I tried all different approaches from tutorials and from other posts, tried to store the peripheral data in an array to keep the reference but nothing seem to work.

在"didDiscover"和"didConnect"之间，有没有什么步骤可以使我获得一些额外的信息?

Is there any step which I can get some extra info between 'didDiscover' and 'didConnect'?

在iPhone上使用Swift 4和iOS 11.2在XCode 9.2中工作.

Working in XCode 9.2, using Swift 4 and iOS 11.2 on iPhone.

这是我的代码:

let deviceName = "AirPods de Roger"
var isConnected = false

var manager: CBCentralManager!
var peripheralBLE: CBPeripheral?

override func viewDidLoad() {
    super.viewDidLoad()
    manager = CBCentralManager(delegate: self, queue: nil)
}

func centralManagerDidUpdateState(_ central: CBCentralManager) {
    switch manager.state {
    case.poweredOff:
        print("BLE service is powered off")
    case.poweredOn:
        print("BLE service is powered on and scanning")
        manager.scanForPeripherals(withServices: nil, options: nil)
    default:
        print("BLE service in another state")
    }
}

func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber) {
    if peripheral.name == deviceName && isConnected == false {
        self.manager.stopScan()
        self.peripheralBLE = peripheral
        self.peripheralBLE?.delegate = self
        manager.connect(peripheral, options: nil)
        isConnected = true
        print("\(peripheral.name) pre-connected")
    }
}

func centralManager(_ central: CBCentralManager, didConnect peripheral: CBPeripheral) {
    lblConnected.isHidden = false
    print("AirPods Connected")
    peripheral.discoverServices(nil)
}

推荐答案

由于AirPods使用kCBAdvDataIsConnectable = 0做广告，因此不应将它们通过BLE连接.

Since the AirPods advertise with kCBAdvDataIsConnectable = 0, they're not supposed to be connected via BLE.
