on Examples AsyncDemo error

[anwfeb]

AsyncDemo:88:20: error: cannot convert 'AsyncWebServer' to 'ESP8266WebServer' {aka 'esp8266webserver::ESP8266WebServerTemplate*'} 88	ElegantOTA.begin(&server); // Start ElegantOTA	^~~
AsyncWebServer*

I got a similar issue with ESP32

error: no matching function for call to 'ElegantOTAClass::begin(AsyncWebServer*)'
   ElegantOTA.begin(&server);

note: candidate: 'void ElegantOTAClass::begin(WebServer*, const char*, const char*)'
     void begin(ELEGANTOTA_WEBSERVER *server, const char * username = "", const char * password = "");

note:   no known conversion for argument 1 from 'AsyncWebServer*' to 'WebServer*'

(and a host of other errors about mismatching definitions - probably due to that incompatibility with AsyncWebServer)

Although the example explicitly refers to ESPAsyncWebServer.h https://github.com/ayushsharma82/ElegantOTA/blob/master/examples/AsyncDemo/AsyncDemo.ino#L33C1-L34C1

I got the exact same error, cant figure out how to fix it :/

[ayushsharma82]

Did you guys enable Async Mode as per docs before compiling the example?

[bmgmo-iscteiulpt]

Yes, but same error

[ayushsharma82]

Weird, CI gave it a pass. I'll need the following details to further diagnose it:

1. Are you using Arduino IDE or PlatformIO?
2. Which MCU are you using?
3. Board/Platform version of your microcontroller

[bmgmo-iscteiulpt]

Arduino IDE Its an Expressif ESP32-s2 wrover The version I'm not sure how to get it

[bmgmo-iscteiulpt]

When the Async mode is set on the library file, it gives the following errors

[ayushsharma82]

@bmgmo-iscteiulpt This is a different error compared to what this issue was initially created for.

You can fix it by downgrading to a stable "arduino-esp32" release in Board Manager. Currently you are using v3.0.0-alphav2 which is not stable.

[bmgmo-iscteiulpt]

worked! didnt even noticed the alpha version when installed the boards .. thank you!

[ScruffR]

For an older project had it enabled but forgot to do that again after a library update cycle overrode that 😳

[ayushsharma82]

@ScruffR Yeah that's inevitable with Arduino IDE. I'll suggest moving to PlatformIO with this approach so that the async flag is persisted within the project itself. One time learning effort, PIO offers a better experience in terms of compile time etc once you are familiar with it.

@anwfeb Status update on your issue? If it was resolved, please close the issue.

@ayushsharma82 : Please also have a look at issue #141 . The issue itself is solved, but with a manual fix - maybe this can be added by you to the original ? https://github.com/ayushsharma82/ElegantOTA/issues/141#issuecomment-1808890201
