与Windows 7和手机自动（蓝牙配对）-Java 学习之路

目前我在C＃2010中编程USB蓝牙适配器 . 我想以这样一种方式编程，它自动与找到的蓝牙设备配对 . 我不希望用户在手机和Windows 7中手动接受配对请求 . 我正在使用我的手机（X Peria S）来测试这一点 . 这种编程方法是否可行？我尝试使用32feet.net库为蓝牙编码，这是我的代码

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

using InTheHand.Net;
using InTheHand.Net.Bluetooth;
using InTheHand.Net.Sockets;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {

    private Guid service = BluetoothService.BluetoothBase;
    private BluetoothClient bluetoothClient;




    public Form1()
    {
        InitializeComponent();
    }

    private void Search_Bluetooth(object sender, EventArgs e)
    {
        BluetoothRadio.PrimaryRadio.Mode = RadioMode.Discoverable;
        bluetoothClient = new BluetoothClient();
        Cursor.Current = Cursors.WaitCursor;

        BluetoothDeviceInfo [] bluetoothDeviceInfo = bluetoothClient.DiscoverDevices(10);
        comboBox1.DataSource = bluetoothDeviceInfo;
        comboBox1.DisplayMember = "DeviceName";
        comboBox1.ValueMember = "DeviceAddress";
        comboBox1.Focus();
        Cursor.Current = Cursors.Default;
    }

    private void Pair(object sender, EventArgs e)
    {
        if (comboBox1.SelectedValue != null)
        {
            try
            {
                bluetoothClient.Connect(new BluetoothEndPoint((BluetoothAddress)comboBox1.SelectedValue, service));
                MessageBox.Show("Connected");
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);


            }
        }
    }
}
}

当我运行这个项目时，我看到周围的蓝牙设备列表，但是当我想要配对时它给我一个错误说“ A connection attempt failed because the connected party did not properly respond a period of time ”

我认为问题是 private Guid service = BluetoothService.BluetoothBase 但我不确定，我使用正确的 service .BluetoothBase 与我的手机配对吗？

有没有现成的解决方案？任何帮助和建议都非常感谢 .

谢谢 .

您必须知道在身份验证期间将要求的加密狗的PIN .

如果你想连接到例如移动蓝牙RS-232加密狗，您必须知道PIN，但由于缺少用户界面，您不必接受远程设备（RS-232加密狗）上的连接 . 但是你必须在手机上 .

我写了以下界面：

interface IStackAdapter
{
    IList<IRemoteBTDevice> DiscoveredDevices { get; }
    void LoadStack();
    void DoInquiry();
    void DoConnection(IRemoteBTDevice rd);
    void ReleaseLink();
}

接下来，我实现了该接口 for each different bluetooth stack . 这是Widcomm堆栈的连接：

/// <summary>
/// Connects to a remote device.
/// </summary>
/// <param name="rd">Remote device that the adapter is supposed to connect to.</param>
public void DoConnection(IRemoteBTDevice rd)
{
    BluetoothAddress remoteAddress = new BluetoothAddress(Convert.ToInt64(rd.Id, 16));
    BluetoothDeviceInfo bdi = new BluetoothDeviceInfo(remoteAddress);

    try
    {
        if (!bdi.Authenticated)
        {
            string pair = rd.Pin; /* PIN for your dongle */
            bool paired = BluetoothSecurity.PairRequest(bdi.DeviceAddress, pair);
        }
    }
    catch (Exception ex)
    {
        //Log and rethrow
    } 
}

如果您使用Windows Phone，则可以使用Windows Phone中的PeerFinder进行连接：

PeerFinder.AlternateIdentities["Bluetooth:PAIRED"] = "";
        var available_devices = await PeerFinder.FindAllPeersAsync();
        HostName hostName = null;
        for (int i = 0; i < available_devices.Count; i++)
        {
            PeerInformation dispositivo = available_devices[i];
            if (dispositivo.DisplayName.ToUpper() == /*Name of you device */)
            {
                hostName = dispositivo.HostName;
                break;
            }
        }
        if (hostName != null)
        {
            var socket = new StreamSocket();
            await socket.ConnectAsync(hostName, "1");
        }
