VC 蓝牙编程问题，纠结中

[aisq]

想请问下关于VC下蓝牙编程的问题，现在我的问题是用win socket编程，总是连接不上，connect函数总是返回10049，说什么地址不正确，我是照着官网的例子做的，还是有问题，唉。

我想实现的功能是，利用win8平板上自带的蓝牙设备，和我的蓝牙板通信。

附上我的代码吧：

int wmain()
{
	WSADATA wsaData;
	/* Use the MAKEWORD(lowbyte, highbyte) macro declared in Windef.h */
    if(0 != WSAStartup(MAKEWORD(2, 2), &wsaData))
    {
		//使用Winsock DLL 
        printf("Initialize socket dll failed.\n");
        return FALSE;
    }
	
	//确认持WinSock DLL是否支 2.2版本
    if(2 != HIBYTE(wsaData.wVersion) || 2 != LOBYTE(wsaData.wVersion))
    {
        printf("Socket version not supported.\n");

    }
	else
	{		
        printf("The Winsock 2.2 dll was found okay\n");

		WSAQUERYSET querySet;
		HANDLE hLookup;
		DWORD flags = LUP_RETURN_NAME | LUP_RETURN_ADDR; 
		
		union
		{
			CHAR buf[5000];
			double __unused; // ensure proper alignment
		};
		
		LPWSAQUERYSET pwsaResults = (LPWSAQUERYSET) buf;
		DWORD dwSize = sizeof(buf);
		BOOL bHaveName;
		ZeroMemory(&querySet, sizeof(querySet));
		querySet.dwSize = sizeof(querySet);
		querySet.dwNameSpace = NS_BTH;

		if (ERROR_SUCCESS != WSALookupServiceBegin (&querySet, LUP_CONTAINERS, &hLookup))
		{
			return (-1);
		}
		
		ZeroMemory(pwsaResults, sizeof(WSAQUERYSET));
		pwsaResults->dwSize = sizeof(WSAQUERYSET);
		pwsaResults->dwNameSpace = NS_BTH;
		pwsaResults->lpBlob = NULL;
		BOOL bError = FALSE;
		while ( TRUE )
		{
			if ( ERROR_SUCCESS == WSALookupServiceNext (hLookup, flags, &dwSize, pwsaResults) )
			{
				//ASSERT (pwsaResults->dwNumberOfCsAddrs == 1);
				BTH_ADDR b = ((SOCKADDR_BTH *)pwsaResults->lpcsaBuffer->RemoteAddr.lpSockaddr)->btAddr;
				bHaveName = pwsaResults->lpszServiceInstanceName && *(pwsaResults->lpszServiceInstanceName);
				t_RemoteBthDevInfo RemoteBthDevInfo;
				if ( bHaveName )
				{
					
					//printf("divice:  %s", pwsaResults->lpszServiceInstanceName);
				}
				
					printf("divice:  %s", pwsaResults->lpszServiceInstanceName);
				RemoteBthDevInfo.RemoteAddr = b;
				
				CSADDR_INFO* pCSAddr = (CSADDR_INFO *)pwsaResults->lpcsaBuffer;
				RemoteBthDevInfo.LocalAddr = ((SOCKADDR_BTH *)pCSAddr->LocalAddr.lpSockaddr)->btAddr;




				GUID ServerGuid = g_guidServiceClass;
				
				SOCKET m_socketClient;
				
				m_socketClient = socket (AF_BTH, SOCK_STREAM, BTHPROTO_RFCOMM);
				if (m_socketClient == INVALID_SOCKET) 
				{
					return WSAGetLastError();
				}
				else
				{				
					printf("=CRITICAL= | socket() call failed. WSAGetLastError = [%d]\n", WSAGetLastError());	
				}
				
				
				
				printf("*INFO* | socket() call succeeded. Socket = [0x%X]\n", m_socketClient);
				printf("*INFO* | connect() attempt with Remote BTHAddr = [0x%X]\n", RemoteBthDevInfo.RemoteAddr);

				SOCKADDR_BTH sa;
				memset (&sa, 0, sizeof(sa));
				sa.addressFamily = AF_BTH;
				sa.serviceClassId = ServerGuid;
				sa.btAddr = RemoteBthDevInfo.RemoteAddr;
				if (connect (m_socketClient, (SOCKADDR *)&sa, sizeof(sa)) == SOCKET_ERROR) 
				{
					m_socketClient = INVALID_SOCKET;
					
					printf("connect failed:  %d", WSAGetLastError());
					return WSAGetLastError();
				}
				else
				{				
					printf("connect success!");
				}

					


				
				//TRACE (L"%s ( %04x%08x )\n", RemoteBthDevInfo.szName, GET_NAP(b), GET_SAP(b) );
				//Add_RemoteBthDevInfo ( RemoteBthDevInfo );
			}
			else
			{
				if ( WSAGetLastError() != WSA_E_NO_MORE )
				{
					bError = TRUE;
					printf("Lookup bluetooth device failed:  %d", WSAGetLastError());
				}
				break;
			}
		}
		WSALookupServiceEnd(hLookup);
	
	}


	//Winsock dll使用完后，清理并退出
    WSACleanup();
}

现在的问题，总是connect时失败，我的环境是VC6.0 + Win xp sp3，装了个SDK是 Windows Server 2003 PSDK February 2003 Edition版本的。

有哪位大神做过windows下的蓝牙开发，给点思路吧。

万恶的windows，蓝牙居然搞得这么差

1.检查ServerGuid具体值是多少？ 2.检查RemoteBthDevInfo.RemoteAddr具体值是多少？ SOCKADDR_BTH sa; memset (&sa, 0, sizeof(sa)); sa.addressFamily = AF_BTH; // sa.serviceClassId = ServerGuid; // 这句慎重使用，要看目标蓝牙设备是否提供ServerClassId sa.port = nPort; // 改用这句通用性更强，nPort = {0, 31}，表示蓝牙通道,共32个通道。0和31为系统保留，应用程序就别用了。一般的蓝牙设备至少一个通道，nPort = 1 即可。 sa.btAddr = RemoteBthDevInfo.RemoteAddr;

看看这篇文章，或许对你有帮助。 http://www.cnblogs.com/EdmundDwyane/p/3292454.html

你好，我想请问下你那个蓝牙解决了没有；我也遇到这个问题，一直连接不上，给了高分也没有人回答； 我现在是win8 pad开发 支持4.0；不知道是winsock API问题还是咋的 连接部上；只能发现设备 谢谢

[赵4老师]

看看电脑键盘或面板或侧面有没有开关管蓝牙的.

据说VC版本要2005以上
