使用 32 英尺通过蓝牙将文件传输到 iphone

tranfer file via bluetooth to iphone using 32feet

我正在尝试使用 32 英尺蓝牙将文件传输到我的 iphone,但似乎无法通过 ObexWebResponse。

我已经阅读了很多 post,但 none 的解决方案似乎对我有用。

我得到的错误是
// 连接失败
// 请求的地址在其上下文中无效 "address:Guid"

    private BluetoothClient _bluetoothClient;
    private BluetoothComponent _bluetoothComponent;
    private List<BluetoothDeviceInfo> _inRangeBluetoothDevices;
    private BluetoothDeviceInfo _hlkBoardDevice;
    private EventHandler<BluetoothWin32AuthenticationEventArgs> _bluetoothAuthenticatorHandler;
    private BluetoothWin32Authentication _bluetoothAuthenticator;

    public BTooth() {
        _bluetoothClient = new BluetoothClient();
        _bluetoothComponent = new BluetoothComponent(_bluetoothClient);
        _inRangeBluetoothDevices = new List<BluetoothDeviceInfo>();
        _bluetoothAuthenticatorHandler = new EventHandler<BluetoothWin32AuthenticationEventArgs>(_bluetoothAutenticator_handlePairingRequest);
        _bluetoothAuthenticator = new BluetoothWin32Authentication(_bluetoothAuthenticatorHandler);

        _bluetoothComponent.DiscoverDevicesProgress += _bluetoothComponent_DiscoverDevicesProgress;
        _bluetoothComponent.DiscoverDevicesComplete += _bluetoothComponent_DiscoverDevicesComplete;

        ConnectAsync();

    }

    public void ConnectAsync() {
        _inRangeBluetoothDevices.Clear();
        _hlkBoardDevice = null;
        _bluetoothComponent.DiscoverDevicesAsync(255, true, true, true, false, null);
    }

    private void PairWithBoard() {
        Console.WriteLine("Pairing...");

        bool pairResult = BluetoothSecurity.PairRequest(_hlkBoardDevice.DeviceAddress, null);

        if (pairResult) {
            Console.WriteLine("Success");
            Console.WriteLine($"Authenticated equals {_hlkBoardDevice.Authenticated}");
        } else {
            Console.WriteLine("Fail"); // Instantly fails
        }
    }

    private void _bluetoothComponent_DiscoverDevicesProgress(object sender, DiscoverDevicesEventArgs e) { _inRangeBluetoothDevices.AddRange(e.Devices); }

    private void _bluetoothComponent_DiscoverDevicesComplete(object sender, DiscoverDevicesEventArgs e) {
        for (int i = 0; i < _inRangeBluetoothDevices.Count; ++i) {
            if (_inRangeBluetoothDevices[i].DeviceName == "Uranus") {
                _hlkBoardDevice = _inRangeBluetoothDevices[i];
                PairWithBoard();
                TransferFile();
                return;
            }
        }
        // no devices found
    }

    private void _bluetoothAutenticator_handlePairingRequest(object sender, BluetoothWin32AuthenticationEventArgs e) {
        e.Confirm = true; // Never reach this line
    }

    // not working
    // transfers a file to the phone
    public void TransferFile() {
        string file = "E:\test.txt",
            filename = System.IO.Path.GetFileName(file);
        string deviceAddr = _hlkBoardDevice.DeviceAddress.ToString();
        BluetoothAddress addr = BluetoothAddress.Parse(deviceAddr);

       _bluetoothClient.Connect(BluetoothAddress.Parse(deviceAddr), BluetoothService.SerialPort);

       Uri u = new Uri($"obex://{deviceAddr}/{file}");
       ObexWebRequest owr = new ObexWebRequest(u);

       owr.ReadFile(file);
       // error:
       // Connect failed
       // The requested address is not valid in its context ...
       var response = (ObexWebResponse)owr.GetResponse();

       Console.WriteLine("Response Code: {0} (0x{0:X})", response.StatusCode);

       response.Close();

    }

配对和身份验证工作正常,我可以让 BluetoothService.Handsfree 为我打电话,但文件传输失败。不知道实际错误是什么,我尝试了几乎所有可用的服务,但没有成功。

你能帮我弄清楚这是怎么回事吗?这是我第一次尝试使用蓝牙服务,所以我还有很多东西要学。

是否可以通过蓝牙将文件从 iPhone 传输到 Windows 桌面?

但是,如果您需要从 Android 设备传输媒体文件(图像、视频等),您可以使用 ObexListener class 提供通过 32Feet 库为此目的,然后您可以简单地调用 _obexListener.GetContext() 方法,该方法将阻塞并等待传入​​连接。

接收到新连接后,您可以将接收到的文件保存到本地存储,如下例所示:

ObexListener _listener = new ObexListener();
_listener.Start();

// This method will block and wait for incoming connections
ObexListenerContext _context = _listener.GetContext();

// Once new connection is received, you can save the file to local storage
_context.Request.WriteFile(@"c:\sample.jpg");

注意:在 Windows 上使用 OBEX 时,确保禁用 "Bluetooth OBEX Service" Windows 服务,以免让它处理传入的 OBEX 请求,而不是所需的应用程序。

我离开了一段时间。并开始尝试使用 xamiren,但后来不得不创建一个虚拟 Mac,这样我就可以让苹果商店在我的 phone 上加载软件。从那里开始,xamerin 'should' 工作得很好,但它是另一个领域,还有很多东西需要弄清楚。
