请问CC3200的SmartConfig如何保存连接profile呢？
我根据httpserver的这个例程写了个用smartconfig连接外部路由器的程序在cc3200 launchpad上运行，但是麻烦的是每次断电再插上都要重新使用smartconfig配置连接。
我对httpserver的修改主要是下边这块：
static int g_iWlanAccess = -1; //初始化
void SimpleLinkWlanEventHandler(SlWlanEvent_t *pWlanEvent)
...
case SL_WLAN_CONNECT_EVENT:
{
SET_STATUS_BIT(g_ulStatus, STATUS_BIT_CONNECTION);
//
// Information about the connected AP (like name, MAC etc) will be
// available in 'slWlanConnectAsyncResponse_t'-Applications
// can use it if required
//
// slWlanConnectAsyncResponse_t *pEventData = NULL;
// pEventData = &pWlanEvent->EventData.STAandP2PModeWlanConnected;
//
// Copy new connection SSID and BSSID to global parameters
memcpy(g_ucConnectionSSID,pWlanEvent->EventData.
STAandP2PModeWlanConnected.ssid_name,
pWlanEvent->EventData.STAandP2PModeWlanConnected.ssid_len);
memcpy(g_ucConnectionBSSID,
pWlanEvent->EventData.STAandP2PModeWlanConnected.bssid,
SL_BSSID_LENGTH);
UART_PRINT("[WLAN EVENT] STA Connected to the AP: %s ,"
"BSSID: %x:%x:%x:%x:%x:%x\n\r",
g_ucConnectionSSID,g_ucConnectionBSSID[0],
g_ucConnectionBSSID[1],g_ucConnectionBSSID[2],
g_ucConnectionBSSID[3],g_ucConnectionBSSID[4],
g_ucConnectionBSSID[5]);
g_iWlanAccess = 0; // 在这里将g_iWlanAccess设置为0
}
....
在static long ConfigureSimpleLinkToDefaultState()中，我期待的是在一开始调用sl_Start的时候就会将g_iWlanAccess设置为0，所以在下边添加了一个判断：
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.FwVersion[0],ver.ChipFwAndPhyVersion.FwVersion[1],
ver.ChipFwAndPhyVersion.FwVersion[2],ver.ChipFwAndPhyVersion.FwVersion[3],
ver.ChipFwAndPhyVersion.PhyVersion[0],ver.ChipFwAndPhyVersion.PhyVersion[1],
ver.ChipFwAndPhyVersion.PhyVersion[2],ver.ChipFwAndPhyVersion.PhyVersion[3]);
if (g_iWlanAccess == 0) // 如果已经连上了路由器AP，不在继续设置smartconfig
{
return lRetVal;
}
// Set connection policy to Auto + SmartConfig
// (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);
但是上面的代码好像没有起作用，当我断电重插板子或者按reset键后，都重新进入smartconfig模式了。
因为smartconfig是不能读出密码的，只能读到ssd，所以貌似也没上面办法把密码保存起来。那么请问应如何修改代码才能记住这个连接呢？
非常感谢！
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.FwVersion[0],ver.ChipFwAndPhyVersion.FwVersion[1],
ver.ChipFwAndPhyVersion.FwVersion[2],ver.ChipFwAndPhyVersion.FwVersion[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
