Tom Bee asked 1 year ago

Greetings, I just downloaded your “MicroPython Programming with ESP32 and ESP8266 eBook” and am using a WEMOS D1 Mini ver4.0. The first exercise (lighting the onboard LED ) works with the REPL but when I try to run the file by pressing the “RST” button on the device it will not run. In “Mu” under the “Files on your device” it shows the Main.py and the Boot.py.

Hi.
That issue usually happens when the files are not uploaded to the board or don’t have the right names.

The names of the files should be main.py and boot.py with lowercase.
