是，the reference documentation is available on MSDN。

32feet.NET是C＃包装程序，available here。配对信息为here。

Python是一个诱人且总体上很简单的解决方案，但是PyBlueZ在这里没有公开Windows蓝牙身份验证API：https://msdn.microsoft.com/en-us/library/windows/desktop/cc766819(v=vs.85).aspx

解决此问题的一种方法是创建一个命令行工具，并通过Python使用它。要为Windows创建命令行工具，请使用Visual Studio并将必要的库添加到项目链接器属性中：Bthprops.lib和ws2_32.lib

以下是一个项目的代码，该项目使用1个参数MAC地址来制作命令行工具，该参数使用“ Just Works”配对将指定的设备配对。请参阅注释的代码以使用密码配对。

#include "stdafx.h"
#include <initguid.h>
#include <winsock2.h>
#include <BluetoothAPIs.h>
#include <ws2bth.h>

BOOL WINAPI BluetoothAuthCallback(LPVOID pvParam, PBLUETOOTH_AUTHENTICATION_CALLBACK_PARAMS pAuthCallbackParams);

int _tmain(int argc, _TCHAR* argv[])
{
    SOCKADDR_BTH sa = { 0 };
    int sa_len = sizeof(sa);
    DWORD dwRet;
    BLUETOOTH_DEVICE_INFO  btdi = { 0 };
    HBLUETOOTH_AUTHENTICATION_REGISTRATION hRegHandle = 0;

    // initialize windows sockets
    WORD wVersionRequested;
    WSADATA wsaData;
    wVersionRequested = MAKEWORD(2, 0);
    if (WSAStartup(wVersionRequested, &wsaData) != 0) {
        ExitProcess(2);
    }

    // parse the specified Bluetooth address
    if (argc < 2) {
        fprintf(stderr, "usage: csbtpair <addr>\n"
            "\n  addr must be in the form (XX:XX:XX:XX:XX:XX)");
        ExitProcess(2);
    }
    if (SOCKET_ERROR == WSAStringToAddress(argv[1], AF_BTH,
        NULL, (LPSOCKADDR)&sa, &sa_len)) {
        ExitProcess(2);
    }

    // setup device info
    btdi.dwSize = sizeof(BLUETOOTH_DEVICE_INFO);
    btdi.Address.ullLong = sa.btAddr;
    btdi.ulClassofDevice = 0;
    btdi.fConnected = false;
    btdi.fRemembered = false;
    btdi.fAuthenticated = false;

    // register authentication callback. this prevents UI from showing up.
    dwRet = BluetoothRegisterForAuthenticationEx(&btdi, &hRegHandle, &BluetoothAuthCallback, NULL);
    if (dwRet != ERROR_SUCCESS)
    {
        fprintf(stderr, "BluetoothRegisterForAuthenticationEx ret %d\n", dwRet);
        ExitProcess(2);

        }
        else if (dwRet == ERROR_INVALID_PARAMETER)
        {

        }
        else if (dwRet == ERROR_NO_MORE_ITEMS)

代替您自己创建，您可以尝试使用以下预制的解决方案：http://bluetoothinstaller.com/bluetooth-command-line-tools/它不适用于我的特定解决方案。

然后，您将需要以管理员身份从python运行已下载或自定义的命令行工具。为了可靠地做到这一点，我建议您使用stackoverflow问题：How to run python script with elevated privilege on windows

我遇到相同的问题，并且已经解决了这个问题，也许您可​​以尝试：

  1. 制作一个名为pairtool.exe的Windows工具，它可以帮助您与命令行配对。关键api是BluetoothAuthenticateDevice，请参考功能文档

    dwRet = BluetoothAuthenticateDevice(NULL, NULL, &btdi, L"1234", 4);
if(dwRet != ERROR_SUCCESS)
{
    fprintf(stderr, "BluetoothAuthenticateDevice ret %d\n", dwRet);
    ExitProcess(2);
}

  2. python代码：

    def connect2Btdev(devName):
#found the device addr
addr = inquiry(devName)
if addr == None:
   return None

#pairing with pairtool.exe
cmd=r'%s %s' % ('pairtool.exe',addr)
ret = os.system(cmd)

if ret <> 0:
    return None

这里是pairtool.exe的所有代码：

#include "stdafx.h"
#include <initguid.h>
#include <winsock2.h>
#include <BluetoothAPIs.h>
#include <ws2bth.h>

bool BluetoothAuthCallback(LPVOID pvParam, PBLUETOOTH_AUTHENTICATION_CALLBACK_PARAMS pAuthCallbackParams)
{
    DWORD dwRet;

    fprintf(stderr, "BluetoothAuthCallback 0x%x\n", pAuthCallbackParams->deviceInfo.Address.ullLong);

    dwRet = BluetoothSendAuthenticationResponse(NULL, &(pAuthCallbackParams->deviceInfo), L"1234");
    if(dwRet != ERROR_SUCCESS)
    {
        fprintf(stderr, "BluetoothSendAuthenticationResponse ret %d\n", dwRet);
        ExitProcess(2);
        return 1;
    }
    fprintf(stderr, "BluetoothAuthCallback finish\n");
    ExitProcess(0);
    return 1;
}

int _tmain(int argc, _TCHAR* argv[])
{
    SOCKADDR_BTH sa = { 0 };
    int sa_len = sizeof(sa);
    DWORD dwRet;
    BLUETOOTH_DEVICE_INFO  btdi = {0};
    HBLUETOOTH_AUTHENTICATION_REGISTRATION hRegHandle = 0;

    // initialize windows sockets
    WORD wVersionRequested;
    WSADATA wsaData;
    wVersionRequested = MAKEWORD( 2, 0 );
    if( WSAStartup( wVersionRequested, &wsaData ) != 0 ) {
        ExitProcess(2);
    }

    // parse the specified Bluetooth address
    if( argc < 2 ) {
        fprintf(stderr, "usage: rfcomm-client <addr>\n"
                "\n  addr must be in the form (XX:XX:XX:XX:XX:XX)");
        ExitProcess(2);
    }
    if( SOCKET_ERROR == WSAStringToAddress( argv[1], AF_BTH,
                NULL, (LPSOCKADDR) &sa, &sa_len ) ) {
        ExitProcess(2);
    }

    //注册回调函数
    btdi.dwSize = sizeof(BLUETOOTH_DEVICE_INFO);
    btdi.Address.ullLong = sa.btAddr;
    btdi.ulClassofDevice = 0;
    btdi.fConnected = false;
    btdi.fRemembered = false;
    btdi.fAuthenticated = false;

    dwRet = BluetoothRegisterForAuthenticationEx(&btdi, &hRegHandle, &BluetoothAuthCallback, NULL);
    if(dwRet != ERROR_SUCCESS)
    {
        fprintf(stderr, "BluetoothRegisterForAuthenticationEx ret %d\n", dwRet);
        ExitProcess(2);
    }

    dwRet = BluetoothAuthenticateDevice(NULL, NULL, &btdi, L"1234", 4);
    if(dwRet != ERROR_SUCCESS)
    {
        fprintf(stderr, "BluetoothAuthenticateDevice ret %d\n", dwRet);
        ExitProcess(2);
    }

    Sleep(1000);
      fprintf(stderr, "pairing finish\n");
    ExitProcess(0);

    return 0;
}

您可以使用MSDN Bluetooth Functions中记录的功能来这样做。

这些使可以通过编程方式搜索和配对蓝牙设备。

Microsoft引入了可用于UWP和传统应用程序的Windows.Devices.Enumeration API，这使蓝牙设备的配对非常容易（有关详细信息，请参阅the official C# and C++ example）。据我了解，内置“蓝牙和其他设备” UI对话框使用的API。作为可以使用此API编写的控制台实用程序的示例，您可以看一下我的控制台BluetoothDevicePairing实用程序。
