蓝牙配对成功后怎么接收数据？

用socket能只写接收数据的代码么？设备的配对直接手工完成。具体要怎么写？有相关的demo参考么？

那又如何取消已经配对好的蓝牙设备呢？

我在网上找到了一段代码来枚举设备，下一步在PC上要做什么？枚举到多个设备后怎么确定要使用的那个设备？



//初始化winsock

	wVersionRequested = MAKEWORD(2, 2);

	if( WSAStartup( wVersionRequested,&wsadata ) )

	{

		AfxMessageBox(_T("WSAStartup failed"));

		WSAGetLastError();

	}

	//初始化蓝牙枚举结构

	DWORD dwWsaqsLen = sizeof( WSAQUERYSET );

	LPWSAQUERYSET lpWsaqs = ( LPWSAQUERYSET )HeapAlloc( GetProcessHeap(),HEAP_ZERO_MEMORY,dwWsaqsLen );

	lpWsaqs->dwSize = sizeof( WSAQUERYSET );

	lpWsaqs->dwNameSpace = NS_BTH;

	//开始枚举蓝牙设备

	DWORD dwWsaqsFlags = LUP_CONTAINERS | LUP_FLUSHCACHE | LUP_RETURN_NAME | LUP_RETURN_ADDR;

	HANDLE hService;

	if( WSALookupServiceBegin( lpWsaqs,dwWsaqsFlags,&hService )!=SOCKET_ERROR )

	{

		bool bFinished = false;

		while( !bFinished )

		{

			if( WSALookupServiceNext( hService,dwWsaqsFlags,&dwWsaqsLen,lpWsaqs ) == NO_ERROR )

			{

				SOCKADDR_BTH *saBth = (SOCKADDR_BTH*)lpWsaqs->lpcsaBuffer->RemoteAddr.lpSockaddr;

				BTH_ADDR bthAddr = saBth->btAddr;

				TRACE( "\n发现蓝牙设备:\n" );

				TRACE( "------------------\n" );

				TRACE( "NAP:0x%04X SAP:0x%08X 设备名称:%s\n", GET_NAP( bthAddr ),GET_SAP( bthAddr ),lpWsaqs->lpszServiceInstanceName );

			}

			else

			{	

				//错误处理

				switch( WSAGetLastError() )

				{

				 //所给缓冲区过小，重新申请

				 case WSAEFAULT: 

					 HeapFree( GetProcessHeap(),0,lpWsaqs );

					 lpWsaqs = ( LPWSAQUERYSET )HeapAlloc( GetProcessHeap(),HEAP_ZERO_MEMORY,dwWsaqsLen );

					 break;

				 //没有更多蓝牙设备

				 case WSA_E_NO_MORE:

					 bFinished = true;

					 break;

				 default:

					 break;

				}

			}

		}

	WSALookupServiceEnd( hService );

	//释放资源

	HeapFree( GetProcessHeap(),0,lpWsaqs );

	WSACleanup();

	}
