windows 蓝牙 API使用

Question

如何通过BluetoothAuthenticateDeviceEx配对蓝牙鼠标，回调函数里面怎么写，有没有对应的demo或者示例代码看看？

Answer 1

1。 配对代码
BOOL CBluetooth::BtSocketAuthenticate(char *szAddr)
{
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) {
    return FALSE;
}

dwRet = BluetoothRegisterForAuthenticationEx(&m_device.bdi, &hRegHandle, &BluetoothAuthCallback, NULL);
if (dwRet != ERROR_SUCCESS)
{
    return FALSE;
}

if ( m_device.bdi.fAuthenticated ) 
{   
    return TRUE;    // 已经配对了
}

DWORD status = BluetoothUpdateDeviceRecord ( &m_device.bdi );
if ( ERROR_SUCCESS != status )
    return FALSE;

// authenticate device (will call authentication callback)
AUTHENTICATION_REQUIREMENTS authreqs = MITMProtectionRequired ;
dwRet = BluetoothAuthenticateDeviceEx(NULL, m_radio.hRadio , &m_device.bdi, NULL, authreqs);

}
2.回调函数
BOOL CALLBACK BluetoothAuthCallback(LPVOID pvParam, PBLUETOOTH_AUTHENTICATION_CALLBACK_PARAMS pAuthCallbackParams)
{
DWORD dwRet;

BLUETOOTH_AUTHENTICATE_RESPONSE AuthRes;
AuthRes.authMethod = pAuthCallbackParams->authenticationMethod;

AuthRes.bthAddressRemote = pAuthCallbackParams->deviceInfo.Address;
AuthRes.negativeResponse = FALSE;
AuthRes.numericCompInfo.NumericValue = pAuthCallbackParams->Numeric_Value;

// Send authentication response to authenticate device
dwRet = BluetoothSendAuthenticationResponseEx(NULL, &AuthRes);

}
//正在测试，可能会有点小bug，一人计短，一起研究
