arduinoWebSockets

I would like to use the ESP32 in Async Mode with the websocket library. It appears that the trigger for this is NETWORK_ESP8266_ASYNC as further into that branch, there is a check for ESP32.

This is not clear to me and I would hate to put references to the ESP8266 in my ESP32 project. That will cause confusion to my future self.

does the ESP32 have a async backend? the lib is using ESPAsyncTCP for the ESP8266. if there is a equivalent for the ESP32, integrating a new Network option is possible. if the ESP32 lib shares the same API then the ESPAsyncTCP variant its easy, otherwise it requires some work.

Yes It is called AsyncTCP

Look here for an example: https://github.com/me-no-dev/ESPAsyncWebServer

ESPAsyncWebServer implements only server side of webSockets. We also need client...

@n9wxu You copied a link to the server.

@petr-fiala @Links2004 I am not sure if it is the exact same API but it shares a lot with ESPAsynTCP.

@CelliesProjects i tried to use AsyncTCP with arduinoWebSockets on esp32, i managed to integrate it, but it was crashing like crazy, every 1 - 5 second esp32 restarted.. my guess is that there is too may dynamic allocations, after few seconds i always ended up with f*cked up (fragmented) memory which causes esp32 restart. I also tryed to fix it, remove as many dynamic allocations as i could but i wasnt successful.

I'm using arduinoWebSockets for realtime video transfer between two esp32s, so any leaks or significant memory fragmentation will make it crash in a few seconds. @Links2004 should try to integrate AsyncTCP, it would be absolutely awesome to have async arduinoWebSockets for esp32.
