cannot compile with arduino ide

[Denyreal]

Hi hope you're doing well

Thank you for your work.

As a newbie i'm a little sad to see absolutely ZERO instructions. :(

my board is :

https://www.wemos.cc/en/latest/s2/s2_mini.html

my board manager is

• esp32 by espressif 2.0.14

i tried compile via arduinoIDE 2.3.1

• AsyncTCP 1.1.4
• ESP Async Webserver 2.7.0

i got errors :

Compilation error: variable or field 'sendwebmsg' declared void

I tried to downgrade to 2.5.1 with the same result.

Any hint of help would be greatly appreciated.

Thank you ;)

You need to rename AsyncWebServerRequest to AsyncWebSrv in your ino file. or something like that. Let me find it.

Did you resolve this issue? Am stumbling on it right now

install the esp32 core 2.0.14 as it seems to be the last one that does not break too much.
esp-idf 5+ has broken many libraries.
