Hey boys. My new Uno wifi rev2 just arrived and I have one problem. At the beggining I connected my board via USB and tested with example blink program from WifiNiNA and It worked fine. When program is runned and I plug in DC power suply and take off USB, my program is still working. And here is my problem. I'm wondering how I can send program/sketch to my arduino without usb just through WIFI. Is it possible? How I can do it? Another thing is how i can program built-in RGB led? Which pins should I turn on?
