PC程序为什么搜索不到蓝牙设备？

[dog357]

PC为XP SP3，ThinkPad SL400，自带有蓝牙功能，现在我在PC旁边打开手机蓝牙，使用PC的蓝牙搜索，可以搜索到手机蓝牙。
但是我自己编写的程序为什么就搜索不到呢？代码如下：

int _tmain(int argc, _TCHAR* argv[])
{
	WSADATA wsaData;
	DWORD dwResult;
	HANDLE hLookup = 0;
	WSAQUERYSET lpRestrictions;
	GUID guid = SVCID_HOSTNAME;
	dwResult = WSAStartup(MAKEWORD(2,2), &wsaData);

	if (dwResult != 0)
	{
		printf("Cannot startup Winsock, error code %d\n", dwResult);
		exit(1);
	}
	else
		printf("WSAStartup is OK!\n");

	ZeroMemory(&lpRestrictions, sizeof(WSAQUERYSET));
	lpRestrictions.dwSize = sizeof(WSAQUERYSET);
	lpRestrictions.lpServiceClassId = &guid;

	dwResult = WSALookupServiceBegin(&lpRestrictions, LUP_RETURN_NAME, &hLookup);
	if (dwResult != SOCKET_ERROR)
	{
		DWORD dwLength = 0;
		WSAQUERYSET * pqs = NULL;

		printf("WSALookupServiceBegin() is OK!\r\n");

		pqs = (WSAQUERYSET *) malloc(sizeof(WSAQUERYSET) + 100);
		dwLength = sizeof(WSAQUERYSET) + 100;

		do
		{
			if (WSALookupServiceNext(hLookup, 0, &dwLength, pqs) != 0)
			{
				dwResult = WSAGetLastError();
				if((dwResult == WSA_E_NO_MORE) || (dwResult == WSAENOMORE))
				{
					printf("No more record found!\n");
					break;
				}
				printf("WSALookupServiceNext() failed with error code %d\n", WSAGetLastError());
			}
			else
			{
				dwResult = 0;
				printf("WSALookupServiceNext() looks fine!\r\n");
			}

			if (dwResult == WSAEFAULT)
			{
				if (pqs)
				{
					printf("Freeing pqs...\r\n");
					free(pqs);
				}

				// Reallocate

				pqs = (WSAQUERYSET *) malloc(dwLength);
				if (!pqs)
				{
					printf("Could not allocate memory: %d\n", GetLastError());
					exit(2);

				}
				else
				{
					printf("Memory allocated for pqs successfully!\r\n");
					continue;
				}
			}

			// Output it since we have it now
			if ((dwResult == 0) && (pqs))
			{
				printf("  Service instance name: %S\n", pqs->lpszServiceInstanceName);
				printf("  Name space num: %d\r\n", pqs->dwNameSpace);
				printf("  Num of protocols: %d\r\n", pqs->dwNumberOfProtocols);
				//printf("  Version: %d\r\n", pqs->lpVersion->dwVersion);
			}
		} while ((dwResult != WSA_E_NO_MORE) && (dwResult != WSAENOMORE));

		// clean-up

		free(pqs);
		if(WSALookupServiceEnd(hLookup) == 0){
			printf("hLookup handle was released!\n");
		}
		else{
			printf("WSALookupServiceEnd(hLookup) failed with error code %d\n", WSAGetLastError());
		}

	}
	else
	{
		printf("Error on WSALookupServiceBegin: %d\n", WSAGetLastError());
		exit(3);
	}

	if(WSACleanup() == 0){
		printf("WSACleanup() is OK!\n");
	}
	else{
		printf("WSACleanup() failed with error code %d\n", WSAGetLastError());
	}

	printf("按回车键退出!\n");
	char c = getchar();
	return 0;
}

搜索到的结果一直是：
WSAStartup is OK
WSALookupServiceBegin() is OK!
WSALookupServiceNext() looks fine！
Service instance name:FHJUN2007 //这是该PC的电脑名，应该是手机的呀
Name space num:12 //应该是16(NS_BTH)吧，而不是12(NS_DNS)
Num of protocols:0
No more record found!
hLookup handle was released!

搜索到的一直是自己的电脑。。。蓝牙设备无法搜索到

[dog357]

WSALookupServiceBegin提示错误10108，但使用电脑自带的蓝牙搜索，可以搜索到周围的蓝牙模块啊

[pig357]

买块蓝牙模块试试。。。

请问你这个问题解决了没有，我也和你一样的问题啊！
