Unneccesairy wait after connect about esp-wifi-config HOT 3 CLOSED

I couldn’t find API that notifies you when WiFi state changes

from esp-wifi-config.

Indeed, the 'wifi_set_event_handler_cb' routine seemed not to exist when esp-open-rtos forked off.
That is a pity. But we can make a simple hack. Remember that effectively everything else is still on hold at this time.

Instead of the timer call a routine, and that same routine calls itself and sets its own timer again.
Break out of that routine when you got an IP (polling with sdk_wifi_station_get_connect_status). You can poll every 200ms...

In my code I have the routine espconn_browse do the same (removed non-essential code)

void espconn_browse(void *arg)
{
    struct espconn *pespconn = arg;
    //do your thing
    os_timer_disarm(&browse_timer);
    os_timer_setfn(&browse_timer, (os_timer_func_t *)espconn_browse, arg);
    os_timer_arm(&browse_timer, 12000, 0);
}

the browse_timer is external so can be malloc and free

from esp-wifi-config.

Pushed update to poll successful connection every 500ms for max of 15s.
