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.

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?

Good evening, I have been trying to find a solution to my problem for days. I’m using your sketch, but I can not get me back the status of the LED if I refresh the page, the problem does not exist if instead I click on the toggle button, which after being pressed returns the status and updates from on to off and vice versa, I specify that the server is not on arduino but I loaded the index page on a remote server. Thank you for any reply.

Hi and thanks for this great tutorial! Do you have a suggestion on what to modify in the code so that pressing the button turns the LED on for 10 seconds and then it turns off automatically (without a need to press the toggle button)? I tried now for some time with a for loop in the loop section or modifying the handleWebSocketMessage function but all that results in wrong behavior. Could you please point me in the right direction? Thanks!
