下面是我的配对代码 和 回掉函数,我发现,我的电脑主动配对手机,手机上会提示失败:"无法和xxx-pc配对",但是我用手机主动配对电脑,就提示配对成功,请问各位大神,哪里有问题呢?
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. 回掉函数
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);
}
