SETUP CODE
On a brand new device this fills in by itself — nothing to do here.
Setting up a device you've used before?
Plug it into a computer with a USB cable and open the "serial monitor" in the flashing app — the code is printed there every time the device starts up.
WI-FI
Once connected, your device remembers this network and joins it automatically from now on. Can't connect? Look for a Wi-Fi network called "Zoundra-Setup" on your phone and try again from there.
