Prepare the development environment

  • Please download ide from https://www.arduino.cc/en/software

Note

Please use the Legacy IDE (1.8.X), the Arduino IDE 2.X was not tested and won't be supported

  • Install the esp core according your target:

    ☛ If ESP8266

Note

Please use the version 2.5.2 or 2.7.4 only! Do not use any version upper than 2.7.4


    ☛ If ESP32

Note

Please use the version 1.0.4 only! Do not use any version upper than 1.0.4, and only use ESP32 board, other ESP32 flavors(C2, S2, S3, etc) are not supported in this version.

Note

Do not try any version different than the ones provided, they may not work properly.
