The issue names no source file, test, or entry point and only reports difficulty setting up ESP8266 files. Start by reviewing the repository's ESP8266 setup instructions and file layout, then clarify which file is expected and what setup failure must be reproduced. Done requires an explicit setup path and a confirmed working ESP8266 configuration.
