我正在研究一组需要使用的蓝牙设备。他们有一个已知的MAC地址库,所以我可以从枚举列表中选择它们。我遇到问题让系统为我提供当前列表。
BLUETOOTH_RADIO_INFO radioInfo;
radioInfo.dwSize = sizeof(radioInfo);
HRESULT hr = ::BluetoothGetRadioInfo(hRadio, &radioInfo);
BLUETOOTH_DEVICE_SEARCH_PARAMS deviceSearchParams;
memset(&deviceSearchParams, 0, sizeof(deviceSearchParams));
deviceSearchParams.dwSize = sizeof(deviceSearchParams);
deviceSearchParams.fReturnAuthenticated = false;
deviceSearchParams.fReturnRemembered = false;
deviceSearchParams.fReturnUnknown = true;
deviceSearchParams.fReturnConnected = false;
deviceSearchParams.hRadio = hRadio;
HANDLE hDeviceFind = ::BluetoothFindFirstDevice(&deviceSearchParams, &deviceInfo);
我遍历设备列表并挑选出已识别的单位。
似乎我必须重新运行控制面板小程序才能刷新可发现的设备,否则我会得到一个似乎是“记住”的列表(而不是本地,非配对和设备的实际设备列表)打开了。)
建议?
使用XP / VC2008 / MFC

FWIW:如果要重置列表,请使用以下代码:
WORD wVersionRequested = 0x202;
WSADATA m_data;
if ( ::WSAStartup(wVersionRequested, &m_data) == S_OK )
{
WSAQUERYSET querySet;
memset(&querySet, 0, sizeof(querySet));
querySet.dwSize = sizeof(querySet);
querySet.dwNameSpace = NS_BTH;
HANDLE hLookup;
DWORD flags = LUP_RETURN_NAME | LUP_CONTAINERS | LUP_RETURN_ADDR | LUP_FLUSHCACHE | LUP_RETURN_TYPE | LUP_RETURN_BLOB | LUP_RES_SERVICE;
int nResult = WSALookupServiceBegin(&querySet, flags, &hLookup);
WSALookupServiceEnd(hLookup);
WSACleanup();
if( nResult != S_OK ) return FALSE;
else return TRUE;
}
return FALSE;
