Hi ESP-IDF,

I just wunder, how to let ESP32 plays like a traditional static webserver?

My goal ist to let Mongoose Webserver access the virtual filesystem of SD card, and fetch the file that the webserver need.

I got this idea from Mongoose's stock example HERE
This is the code snippet that do the magic, and which also not works on my machine:

Code: Select all

  
  mg_set_protocol_http_websocket(nc);
  s_http_server_opts.document_root = ".";  // Serve current directory
  s_http_server_opts.enable_directory_listing = "yes";
 
---
The following is actually another question:
Right now i just specify one task for Webserver, one for SD Card I/O.
It that possible to pass file pointer between tasks? If yes, is that good practise?

Thanks

Does enable_directory_listing works for ESP32 WROVER with SD card. Does Web browser shows list of folders and files.

Hi I just brought one of these

https://www.ebay.co.uk/itm/Bluetooth-De ... 2749.l2649

I'm hoping to run a web server on it and access the files in the SD card.

What's the best way of doing this with this hardware in 2019?

<edit> This looks promising is it any good
