请问CC3200的SmartConfig如何保存连接profile呢？

因为你在static long ConfigureSimpleLinkToDefaultState()函数里调用了lRetVal = sl_WlanProfileDel(0xFF);，删除了所有的profile，所以系统不会保存用过的profile的SSID和密码。你可以试着不删除profile，然后调用添加profile的函数试试

Thanks Ken. 

但是我sl_WlanProfileDel这块只是在之前没有连上Wlan的时候才会调用啊，请看下边的红色部分，如果把sl_WlanProfileDel去掉会不会在ssid变化的时候不好用呢？

UART_PRINT("Host Driver Version: %s\n\r",SL_DRIVER_VERSION);
UART_PRINT("Build Version %d.%d.%d.%d.31.%d.%d.%d.%d.%d.%d.%d.%d\n\r",
ver.NwpVersion[0],ver.NwpVersion[1],ver.NwpVersion[2],ver.NwpVersion[3],

ver.ChipFwAndPhyVersion.PhyVersion[0],ver.ChipFwAndPhyVersion.PhyVersion[1],
ver.ChipFwAndPhyVersion.PhyVersion[2],ver.ChipFwAndPhyVersion.PhyVersion[3]);

if (g_iWlanAccess == 0) 
{
return lRetVal;
}

// (Device's default connection policy)
lRetVal = sl_WlanPolicySet(SL_POLICY_CONNECTION, 
SL_CONNECTION_POLICY(1, 0, 0, 0, 1), NULL, 0);
ASSERT_ON_ERROR(lRetVal);

// Remove all profiles
lRetVal = sl_WlanProfileDel(0xFF);
ASSERT_ON_ERROR(lRetVal);

另外在连接的时候我直接调用的smartconfig.c的函数：

Report("Use Smart Config Application to configure the device.\n\r");
//Connect Using Smart Config
lRetVal = SmartConfigConnect();
ASSERT_ON_ERROR(lRetVal);

//Waiting for the device to Auto Connect
while(!IS_IP_ACQUIRED(g_ulStatus))
{
MAP_UtilsDelay(500);
}

请问这里还需要加上其他addprofile的代码吗？

非常感谢！

同问，调用SmartConfig.c中的SmartConfigConnect()函数之后，是否就已经将AP添加到了profile里面？

配置完一次之后该如何连接已经保存了的AP

已解决，按键进入Smartconfig配置模式，配置之后会自动保存到profile table，无需再手动添加。不进入配置模式时则自动连接即可。断电可用

lRetVal = sl_Start(NULL,NULL,NULL);

if (lRetVal < 0 || lRetVal != ROLE_STA)

UART_PRINT("Failed to start the device \n\r");

你好，我想问下its default state具体是什么呢？我就把sl_WlanProfileDel(0xFF)l注释掉了，其他的还是ConfigureSimpleLinkToDefaultState()函数里面。但是还是连不上。

1、那个函数就是恢复到最初CC3200的状态，将所有的连接的Profile均删除

2、处理把sl_WlanProfileDel(0xFF)l注释掉，还需要注意Connectify连接的方式配置，如下代码进行了备注和测试
