Hi:

I have the Wemos LOLIN32 Pro board and I cannot upload when compiling. I tried the generic ESP8266 and the NodeMCU 1.0 ESP12E options as suggested in another thread. Neither work. By default I think the board is running Python.

The error I get is it is:

Hi Erel:

Thank you for your response and help. After reading that thread, I may just stick to using the standard ESP8266 boards.

Thanks, Rob
