Hi.
Did you follow the “Preparing the MicroSD Card” section?
Please make sure that you load the index.html, style.css and favicon.png files to the micro sd card, see the section “Copy Files to MicroSD Card”.

Sara

i ran into an odd issue, i copied the code provided, and after loading it to the esp32 it half works, and im not sure why.

i can navigate the SD card and its files through the browser but the browser will not load the index.html page. i can navigate to 192.etc/image.jpg and that loads. i can navigate to 192…/test.txt and that will load. but 192…/index.html just gives a 404 error page unreachable.

i have tried allot. to much to list actually and am rather stumped. any ideas?

Hi, I read the article and will build this. I was wondering if I wrote a ASPX web page that used some DLL files would the Index page serve the ASPX pages correctly to a browser?

That’s a good idea, but I resolve the problem. By error I declare an array of 3 bytes size instead of 30 bytes.

Thanks
