CC3200客户端为什么反复断开、连接后无法再连接?
我用CC3200模块做TCP SERVER时,只有一个TCP客户端反复断开、连接,大概4次以后无法再连接。分析是达到socket连接限制(因为还有其他套接字),但客户端正常断开后 sl_Recv返回0,我在返回0后有关闭套接字,为什么还会出现这种情况呢,请问是什么问题?
while(1){ // waiting for an app incoming TCP connection if ( g_iSockID_App < 0 ) { // accepts a connection form a TCP client, if there is any // otherwise returns SL_EAGAIN g_iSockID_App = sl_Accept(g_iSockID_AppServer, ( struct SlSockAddr_t *)&sAddr, (SlSocklen_t*)&iAddrSize); if (g_iSockID_App == SL_EAGAIN) { //sl_Close(g_iSockID_App); } else if(g_iSockID_App < 0) { // error sl_Close(g_iSockID_App); } else { // setting socket option to make the socket as non blocking enableOption.NonblockingEnabled = 1; //0 = disabled;1 = enabled;default = 1 lRetVal = sl_SetSockOpt(g_iSockID_App,SL_SOL_SOCKET,SL_SO_NONBLOCKING, (_u8 *)&enableOption,sizeof(enableOption)); //enable/disable nonblocking mode if( lRetVal < 0 ) { sl_Close(g_iSockID_App); } } } else { // waits for 1 packets from the connected TCP client lRetVal = sl_Recv(g_iSockID_App, g_cAppTcpBuf, TCP_CMD_RD_BUF_SIZE, 0); if (lRetVal == SL_EAGAIN); else if(lRetVal <=0) { // error sl_Close(g_iSockID_App); g_iSockID_App=SL_EAGAIN; //如果客户端正常断开的返回值为0 UART_PRINT("App client failed,lRetVal=%d
",lRetVal); } else { //run command } }}
你客户端关闭的时候是怎样关闭的呢?
