yes, I saw it, but I saw that the file is not empty, it is the same as the tutorial, but with my wifi data, mqtt, and the controller_config.json the same as on the web. these files are in /data.
when clicking on upload, should they load? or how can I do to load them.
I have everything the same as in the tutorial, I even bought the same board to avoid failures.
Thanks for the help.
