Hello,
thanks for your good work. But, why “JavaScript” ?
Is it possible to write a C++-Code instead Java ?

sincerely, Lutz

In reply to Bruno. Thanks for the info. I had previously tied going to an earlier version but did not go back that far.

In reply to Bob. Downgrade ESPAsyncWebServer to version 3.0.6 and will work.

Greetings:
I haven’t been able to get this program to run.
Everything is OK until I enter the address in my browser then it
errors with this error:

I tried with windows 11 IDE2.3.6 and windows 10 IDE1.8.19 all
with the same results.
I ran the ESP32 version and it works OK.
The two programs are the same except for the libraries.
I am using the Libraries recommended.
ESP AsyncTCP by ESP32Async version 2.0.0
ESP Async WebServer by ESP32Async version 3.8.0
Both say they are for ESP8266 and ESP32
Any help is appreciated.
Bob

initWebSocket();
// Route for root / web page
server.on(“/”, HTTP_GET, [](AsyncWebServerRequest *request){
request->send(200, “text/html”, index_html, processor);

above fct may typo error —-> i.e. missing _P
request->send_P(200, “text/html”, index_html, processor);

I am trying to use AutoconnectAP with this code but there are conflicts in these two libraries. Is there any example where this two libraries are used together?

In reply to Sara Santos. Sorry if I insist, have you had the opportunity to verify the behavior of the page? Last thing, would you help me with a change, I should add another button, but I have to make sure that only one button at a time is ON, example: the first is on, the second is off, if the second is on the first goes off. I hope I have been able to explain what I should do and receive a kind answer to my problems. Thank you in advance.

In reply to Sara Santos.

Thanks for the reply, opening the console I do not receive any message outside of connection attempt and open connection. In the IDE console I only get connected by ID and IP when I log in from outside, while locally I also get the STATE. I insert the link of the remote server where the index page is running in case it can be useful. Thank you. http://185.182.186.170/arduino/

Hi.
Can you open the javascript console on your web browser, refresh the web page and check which messages do you get?
