自己修改的esp8266固件的只能smartconfig一次

[pass1876]

使用官方例程中关于SmartConfig的代码，每次上电都要配置，不能保存，自己修改了一下。结果只能保存一个路由器，更换路由器后不能smartconfig成功。

void ICACHE_FLASH_ATTR wifi_event_handler_cb(System_Event_t * event)
{
uint8 loop = 0;
static uint8 status = EVENT_MAX;
if(event == NULL) {
return;
}
switch(event->event) {
case EVENT_SOFTAPMODE_STACONNECTED:
os_printf("EVENT_SOFTAPMODE_STACONNECTED\r\n"); // station connected
break;
case EVENT_SOFTAPMODE_STADISCONNECTED:
os_printf("EVENT_SOFTAPMODE_STADISCONNECTED\r\n"); // station disconnected
break;
default:
break;
}
}

void ICACHE_FLASH_ATTR
smartconfig_done(sc_status status, void *pdata)
{
switch(status) {
case SC_STATUS_WAIT:
os_printf("SC_STATUS_WAIT\n");
break;
case SC_STATUS_FIND_CHANNEL:
os_printf("SC_STATUS_FIND_CHANNEL\n");
break;
case SC_STATUS_GETTING_SSID_PSWD:
os_printf("SC_STATUS_GETTING_SSID_PSWD\n");
sc_type *type = pdata;
break;
case SC_STATUS_LINK:
os_printf("SC_STATUS_LINK\n");
wifi_station_disconnect();
wifi_station_connect();
struct station_config *sta_conf = pdata;
os_memcpy(s_staconf.ssid,(*sta_conf).ssid,os_strlen((*sta_conf).ssid));
wifi_station_set_config(&s_staconf);
break;
case SC_STATUS_LINK_OVER:
os_printf("SC_STATUS_LINK_OVER\n");
uint8 phone_ip[4] = {0};
os_memcpy(phone_ip, (uint8*)pdata, 4);
os_printf("Phone ip: %d.%d.%d.%d\n",phone_ip[0],phone_ip[1],phone_ip[2],phone_ip[3]);
smartconfig_stop();

break;

}

}

更换路由器之后，会去 smartconfig 吗？

Code: Select all

wifi_station_get_config_default(&s_staconf);
if(os_strlen(s_staconf.ssid) != 0)
{
os_printf("user_scan\r\n");   
system_init_done_cb(user_scan);
}

成功连接过路由器之后，这个 if 条件应该会始终成立吧，是不是每次都走 user_scan 了
