TI工程师，CC3200 tcp_socket问题。。

TCP 当服务器时，需要外部连接，TCP连接成功了

但是这是PC tcp上位机不发送数据时，程序死等在sl_Recv函数。

// waits for 1000 packets from the connected TCP client
while (lLoopCount < g_ulPacketCount)
{
iStatus = sl_Recv(iNewSockID, g_cBsdBuf, iTestBufLen, 0);

// iStatus = sl_Send(iNewSockID, g_cBsdBuf, iTestBufLen, 0);
if( iStatus <= 0 )
{
// error
ASSERT_ON_ERROR( sl_Close(iNewSockID));
ASSERT_ON_ERROR(sl_Close(iSockID));
ASSERT_ON_ERROR(TCP_SERVER_FAILED);
}

lLoopCount++;
}

我添加超时接受，修改相应的参数，也是一样的效果

SlTimeval_t sltimeval;

sltimeval.tv_sec = 0;
sltimeval.tv_usec = 300;

// setting socket option to make the socket as non blocking
iStatus = sl_SetSockOpt(iSockID, SL_SOL_SOCKET, SL_SO_RCVTIMEO ,
&sltimeval, sizeof(sltimeval));

请问TI工程师，怎么修改相应的代码才能够不死等接受数据，不然这样只能加操作系统？

Louis，

您好！

您如果添加了超时接收，那应该是不会出现您说的死等接收的情况发生。根据以往的经验，您更新一下service pack再试一下，谢谢！

谢谢您回复！

service pack应该是最新的。

下面是信息：

[WLAN EVENT] STA Connected to the AP: EmbedSky_test , BSSID: 0:27:19:64:f8:a8

请问有办法解决吗？应该是有的，我还没有找到相关的参数设置？可以提供吗？

通过下面设置参数，没有效果，API我大部分看过了，找不到。

sltimeval.tv_sec = 0;
sltimeval.tv_usec = 300;

// setting socket option to make the socket as non blocking
iStatus = sl_SetSockOpt(iSockID, SL_SOL_SOCKET, SL_SO_RCVTIMEO ,
&sltimeval, sizeof(sltimeval));

你在创建SOCKET之后，加下面这个调用去设置它的类型为non-blocking:

g_NonBlocking = 1;
g_Status = sl_SetSockOpt(g_Socket, SL_SOL_SOCKET, \
SL_SO_NONBLOCKING, &g_NonBlocking, \
sizeof(g_NonBlocking));

已经解决了，确实要这样，被TCP SOCKET例子给忽悠 了，一定要在创建之后，马上设置参数，不能再连接成功修改。

谢谢您！
