This took way more time than planned to get working: ESP32 Dev Kit microcontroller programmed from the command-line, using esptool and platformio running in a Python venv.
Inspired by https://github.com/rgl/platformio-esp32-arduino-hello-world
I documented the steps to get it working in a #codeberg repository:
"This repository describes how to use PlatformIO Core with ESP-32 Dev Kit C V4 boards from AZ-Delivery"
