是的，the reference documentation is available on MSDN。
32feet.NET是一个C#包装器，available here。有关配对的信息是here。

https://msdn.microsoft.com/en-us/library/windows/desktop/cc766819(v=vs.85).aspx是一个诱人的整体简单的解决方案，但是Python在这里没有公开windows蓝牙身份验证API:Python
解决这个问题的一种方法是创建一个命令行工具，并通过Python使用它。若要为Windows创建命令行工具，请使用Visual Studio并将所需的库添加到项目链接器属性中: Bthprops.lib和ws2_32.lib
下面是一个项目的代码，用于制作一个带有一个参数的命令行工具，即MAC地址，它使用"Just Works“配对来配对指定的设备。有关使用密钥配对的信息，请参阅注释代码。

}与其自己创建此解决方案，您可能希望尝试这个预先制作的解决方案：http://bluetoothinstaller.com/bluetooth-command-line-tools/它不适用于我的特定解决方案。
然后，您需要以管理员身份从python运行下载的或自定义的命令行工具。为了可靠地做到这一点，我建议使用堆栈溢出问题：How to run python script with elevated privilege on windows

我遇到了同样的问题，我已经解决了这个问题，也许你可以试试：
- 制作了一个名为pairtool.exe的windows工具，它可以帮助你与命令行配对。关键接口为BluetoothAuthenticateDevice，请参考函数文档
dwRet = BluetoothAuthenticateDevice(NULL，NULL，&btdi，L"1234"，4)；if(dwRet != ERROR_SUCCESS) { fprintf(stderr，"BluetoothAuthenticateDevice ret %d\n"，dwRet)；ExitProcess(2)；}
- python代码：
def connect2Btdev(devName)：#找到设备地址addr =查询(DevName) if addr == None: return None #与pairtool.exe配对=r‘%s %s’% ('pairtool.exe'，addr) ret = os.system(cmd) if ret <> 0: return None
以下是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;
