如何以编程方式配对蓝牙设备

我最近买了一个Lilypad Simblee BLE Board，我想以编程方式将它与我的电脑配对（使用C＃中的32feet.NET库） .

我知道StackOverflow（例如here）已经询问了“如何以编程方式配对蓝牙设备”，但出于某种原因，我所有尝试配对设备 programatically 都失败了 . 的确， I successfully paired the device with the "Manage Bluetooth devices" window in Windows 10 Settings panel （设置>设备>蓝牙） .

首先，我不知道pairing method（遗留系统或SSP）与我的设备一起使用 . Windows从未向我询问过PIN或其他内容，所以我猜它是不确定的's SSP, but I' .

我在Google上搜索了如何使用32feet.NET进行 SSP 配对请求：我找到了this .

但是，一旦它发现我的设备（设备发现正常工作），配对请求立即失败 .

我的代码：

using InTheHand.Net.Bluetooth;
using InTheHand.Net.Sockets;
using System;
using System.Collections.Generic;

namespace HLK_Client
{
    class HLKBoard
    {
        public event HLKBoardEventHandler HLKBoardConnectionComplete;
        public delegate void HLKBoardEventHandler(object sender, HLKBoardEventArgs e);

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


        public HLKBoard()
        {
            _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;
        }


        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");
            }

            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 == "HLK")
                {
                    _hlkBoardDevice = _inRangeBluetoothDevices[i];
                    PairWithBoard();

                    return;
                }
            }

            HLKBoardConnectionComplete(this, new HLKBoardEventArgs(false, "Didn't found any \"HLK\" discoverable device"));
        }

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

知道为什么配对请求失败了吗？
