Storage.write not working when using save on send

Your last line, "onInit ();", do not save to flash.
When you reset, "onInit ();" run automatically.
And I'm waiting to start other features that rely on that
the wifi is connected like this.

    wifi.connect (ssid, {password: password}, function () {
});

   wifi.on ('connected', function () {
     console.log ('Connected to Wifi. IP address is:', wifi.getIP () .ip);
     server start ();
     }
   });

Maybe it can help you further.
