Hey I had the same problem and I solved it by taking exactly the same version as in the instructions on Github. com.
If you haven’t downloaded version 1. 8. 8 [https://www.arduino.cc/en/Main/Donate] of the Arduino software yet, try it.
Sketch Data Upload is enough if it’s there. You don’t have to click on it.
The important thing is that the right board is selected. Then download software and adjust values such as Wifi and static IP.
I hope I could help you.
Sincerely Laurin
