Question

我正在尝试连接到蓝牙设备（Adafruit Flora BLE）并寻找特征数据来附加通知回调。问题是，我没有看到列出的任何特征。我所看到的只是服务本身的属性而没有特征。

以下是一些代码，显示设备标识和查找服务的位置。请原谅意大利面条代码，现在只需调试/黑客攻击原型。

基本上，我正在尝试在arduino / flora模块上为BLE服务设置通知程序，以便我可以通过UART传感器数据发送。我有所有的连接工作，但似乎无法让听众和更新部分工作。谢谢！

func centralManager(central: CBCentralManager, didDiscoverPeripheral peripheral: CBPeripheral, advertisementData: [String : AnyObject], RSSI: NSNumber) {

    let UUID = "818ECB19-BB61-BE95-2D04-64E5D90845EF";

    if (peripheral.identifier.UUIDString == UUID){


       // print("Peripheral found with name: \(peripheral.name)\nUUID: \(peripheral.identifier.UUIDString)\nRSSI: \(RSSI)\nAdvertisement Data: \(advertisementData)")
        visiblePeripheralUUIDs.addObject(peripheral.identifier.UUIDString)
        visiblePeripherals[peripheral.identifier.UUIDString] = Peripheral(peripheral: peripheral, RSSI: RSSI.stringValue, advertisementDictionary: advertisementData)
        tableView.reloadData()
        //
        connectedPeripheral = peripheral
        connectionAttemptTimer = NSTimer.scheduledTimerWithTimeInterval(10, target: self, selector: Selector("timeoutPeripheralConnectionAttempt"), userInfo: nil, repeats: false)
        manager.connectPeripheral(connectedPeripheral!, options: nil)

    }
}

func centralManager(central: CBCentralManager, didConnectPeripheral peripheral: CBPeripheral) {
    //print("Peripheral connected: \(peripheral.name ?? peripheral.identifier.UUIDString)")
    connectionAttemptTimer?.invalidate()
    let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let peripheralViewController = storyboard.instantiateViewControllerWithIdentifier("PeripheralViewController") as! PeripheralViewController
    peripheralViewController.peripheral = peripheral
    navigationController?.pushViewController(peripheralViewController, animated: true)

    print("--------Starting service discovery")

//        print("!!!!!!!!!!Services be present \(peripheral.services?.count)");
//        for service in (peripheral.services)! {
//            print("SERVICES: \(service)")
//        }
    }

    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)
//            }
//        }
    }

`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)
        }
    }
}

更新了didDiscoverCharacteristicsForService，它仍然没有为我在for循环中解析任何东西：

我在这里错过了一些愚蠢的东西吗？
