IOS Swift服务特性

我正在尝试连接到蓝牙设备（Adable），并查找要附加通知回调的特征数据。问题是，我没有看到列出任何特征。我看到的只是服务本身的属性，没有任何特征

下面是一些代码，显示设备标识和查找服务发生的位置。恕我直言，现在只是调试/破解一个原型

基本上，我正在尝试为arduino/flora模块上的BLE服务设置一个通知程序，以便通过UART传感器发送数据。我有所有的连接工作，但似乎无法让侦听器和更新部分工作。谢谢

func startScanning() {
    print("Started scanning.")
    visiblePeripheralUUIDs.removeAllObjects()
    visiblePeripherals.removeAll(keepCapacity: true)
    tableView.reloadData()
    manager.scanForPeripheralsWithServices(nil, options: nil)
    scanTimer = NSTimer.scheduledTimerWithTimeInterval(10, target: self, selector: Selector("stopScanning"), userInfo: nil, repeats: false)
}

更新了DidDiscoveryCharacteristicsForService，但它仍然没有返回任何内容供我在for循环中解析：

`func peripheral(peripheral: CBPeripheral, didDiscoverCharacteristicsForService service: CBService, error: NSError?) {
        print("GOT TO PERIPHERAL")

    if (peripheral != self.peripheral) {
        // Wrong Peripheral
        print("WrONG PERIPHERAL")
        return
    }

    if (error != nil) {
        print(" GOTS US AN ERROR")
        return
    }

    print("What is service:  \(service)")
    for characteristic in service.characteristics! {
        print("CHARACTERISTIC \(characteristic)")
        if characteristic.UUID == service2 {
            print("WHAT THE F*** BRO \(characteristic as CBCharacteristic)");
            peripheral.setNotifyValue(true, forCharacteristic: characteristic as CBCharacteristic)

            // Send notification that Bluetooth is connected and all required characteristics are discovered
            //self.sendBTServiceNotificationWithIsBluetoothConnected(true)
        }
    }
}

我是不是错过了什么蠢事

在

打印（“启动服务发现”）

之后，您需要调用

discoverServices:

。它应该触发

外围设备：DidDiscoveryServices:

然后调用

发现特征：forService:

哪个应该触发

外围设备：DidDiscoveryCharacteristicsForService:错误：

。上面粘贴的更新代码：您没有在

centralManager中调用
外围设备上的
发现服务：
：didConnectPeripheral:
对不起，为了简洁起见，我没有更改，但我确实调用了它。我看到以下内容：以下回调确实执行：func peripal（peripal:cbperipal，didDiscoveryCharacteristicsforService:CBService，error:NSError？）在该回调中，我运行：for characteristic in service.characteristics！{if characteristic.UUID==service1{…..这最终不会计算为true，无论我使用的是CBUUID常量还是UUID的原始字符串。
service1
是
CBService
UUID还是
CBCharacteristic
UUID？请记录
characteristic.UUID
，以确保正确。
    func peripheral(peripheral: CBPeripheral, didDiscoverCharacteristicsForService service: CBService, error: NSError?) {
    print("GOT TO PERIPHERAL")

    if (peripheral != self.peripheral) {
        // Wrong Peripheral
        print("WrONG PERIPHERAL")
        return
    }

    if (error != nil) {
        print(" GOTS US AN ERROR")
        return
    }

    print("CHECKING ON CHARACTERISTICS \(service.UUID)")


//        for characteristic in service.characteristics! {
//            print("CHARACTERISTIC \(characteristic)")
//            if characteristic.UUID == service2 {
//                print("WHAT THE F*** BRO \(characteristic as CBCharacteristic)");
//                peripheral.setNotifyValue(true, forCharacteristic: characteristic as CBCharacteristic)
//                
//                // Send notification that Bluetooth is connected and all required characteristics are discovered
//                //self.sendBTServiceNotificationWithIsBluetoothConnected(true)
