TI中文支持网继续研究CC3200 SDK里面的example, 今天试了TCP socket，感觉不错。
所需工具：
1.wifi路由器一台。
2.网络测试工具软件，我用的网络调试助手。
3.wifi 笔记本一台。
首先gcc编译tcp_socket, 然后用uniflash烧写到flash，并运行程序，串口输出log如下：

Press Enter and run iperf command "iperf.exe -c 192.168.0.101 -i 1 -t 100000"Receiving TCP packets…
Recieved 1 packets successfully
我先选择的是3. 修改测试参数，把测试的pack counts 从1000改为1， 这样数据量小一点，易于测试。
看源码就知道：
// waits for 1000 packets from the connected TCP client
while (lLoopCount < g_ulPacketCount)
{
iStatus = sl_Recv(iNewSockID, g_cBsdBuf, iTestBufLen, 0);
if( iStatus <= 0 )
{
// error
sl_Close(iNewSockID);
sl_Close(iSockID);
ASSERT_ON_ERROR(RECV_ERROR);
}
lLoopCount++;
}
volatile unsigned long g_ulPacketCount = TCP_PACKET_COUNT;
这个循环的次数就是由这个PACK COUNTS 控制的，所以先改这个。
然后选择2，开始接受数据，此时网络测试工具，选择TCP client. 如下图：
点击连接成功后，就可以发送数据了，发完一包数据自动断开，同时cc3200那边显示接收一包数据成功。
Receiving TCP packets…
Recieved 1 packets successfully
Choose Options:
1. Send TCP packets.
2. Receive TCP packets.
3. Settings.
4. Exit
Enter the option to use: 1
Run iperf command "iperf.exe -s -i 1 -t 100" and press Enter
Sending TCP packets…
Sent 1 packets successfully
回到主界面后，再选择1， 发送tcp 数据，网络调试工具选择tcp serer，并连接，如下：
Choose Options:
1. Send TCP packets.
2. Receive TCP packets.
3. Settings.
4. Exit
Enter the option to use: 1
Run iperf command "iperf.exe -s -i 1 -t 100" and press Enter
按回车发送一包数据，发完后， 测试工具接收如下：
一包接收了1400 字节，看代码就知道，
// filling the buffer
for (iCounter=0 ; iCounter<BUF_SIZE ; iCounter++)
{
g_cBsdBuf[iCounter] = (char)(iCounter % 10);
}
sTestBufLen = BUF_SIZE;
// sending multiple packets to the TCP server
while (lLoopCount < g_ulPacketCount)
{
// sending packet
iStatus = sl_Send(iSockID, g_cBsdBuf, sTestBufLen, 0 );
if( iStatus < 0 )
{
// error
sl_Close(iSockID);
ASSERT_ON_ERROR(SEND_ERROR);
}
lLoopCount++;
}
#define IP_ADDR 0xc0a80064 /* 192.168.0.100 */
#define PORT_NUM 5001
#define BUF_SIZE 1400
#define TCP_PACKET_COUNT 1000
那个BUF_SIZE 就是1400.
测试下来，结果和代码的实现完全一致，可以成功实现TCP_SOCKET的功能，也就是说，CC3200既可以做TCP_CLIENT, 发送数据，也可以做TCP_SERVER, 接收数据。
希望对大家有用，谢谢。

感谢楼主的分享，很实用呢
