Question: is it possible to replicate AsyncWebSocket with WebServer in arduino-esp32 v3.0.0 ?

WebServer does not support webSockets. There is a websocket library I used in one of my projects located here It worked well.
Why don't you want to use espAsynchWebserver library for websockets ?

Hi Joseph (@noweare1 ),

This is a great library, it works really well. With arduino-esp32 v3.0.0, there is issue #1391 - but that can be solved. I'm investigating if it is now possible to achieve the same functionality using only the latest espressif core - without needing additional libraries (this and AsyncTCP included). My solution is to use WebServer and esp_http_server simultaneously. esp_http_server is only serving the /ws websocket - on port 81. WebServer is doing everything else - on port 80.

Best wishes,

I didn't know esp_http_server supported websockets. Like you, I try to keep the external libraries to a minimum and try to write my own code if I am up to it. Webservers/Websockets is way above my pay grade though : ). will have to take a look at that library. Since it is part of the IDF it is much better documented with lots of examples. Do you use esprressif-arduino or IDF framework ?

"Do you use esprressif-arduino or IDF framework ?" arduino-esp32

v3.0.0 includes full support for the Wiznet W5500 Ethernet PHY under Arduino. It works very well with other SPI devices - microSD included.
