有一个问题:
有没有办法在Windows上以编程方式配对蓝牙设备?(c ++,c#)
感谢回复。
感谢回复。
是的,MSDN上提供了参考文档。

如果您不想自己创建,可以尝试使用预制解决方案: http://bluetoothinstaller.com/bluetooth-command-line-tools/ 但这并未适用于我的特定解决方案。
接下来,您需要以管理员身份从Python运行下载或自定义的命令行工具。为了可靠地执行此操作,我建议查看stackoverflow问题: 如何在Windows上以提升的权限运行Python脚本
我遇到了同样的问题,但我已经解决了它。也许你可以试一下:
make a windows tool named pairtool.exe, it help you to pairing with command line. the key api is BluetoothAuthenticateDevice, please refering the functions document
dwRet = BluetoothAuthenticateDevice(NULL, NULL, &btdi, L"1234", 4);
if(dwRet != ERROR_SUCCESS)
{
fprintf(stderr, "BluetoothAuthenticateDevice ret %d\n", dwRet);
ExitProcess(2);
}
python code:
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的全部代码:
#include "stdafx.h"

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);
