Hi Sara,
Short update to above problem, updated to IOS18.2 and everything works again as before. So the guys from Apple messed it up, but fortunately they corrected the bug.

I’m sorry for the issue.
I think it’s probably because the web server doesn’t have a certificate.
Maybe it doesn’t allow you to access web pages without certificate for security reasons, even though they are on the same network.

In reply to Sara Santos. Hi Sara, I only have an IPad and not a Mac, so I cannot get a console visible. I do have web-inspector, but that ony works if the page get loaded and that fails. I presume that Apple has changed something in IOS18 that expects something more then send by the ESP8266 webserver. I even reduced the “html” to only 1 line of text, but even that failed. Luckily it still works on Chrome, but I found it annoying that it stop working on Safari, but yeah thats with Apple and Microsoft.

Hi.
I’m not sure what the problem might be.
Do you get more specific errors on the console?

Hi Sara and Rui,
I have used this example in two projects and they work great. I also called-up the webpage on my IPad and that also worked great in Safari, but since my IPad updated to IOS 18, it does not communicate anymore. In Safari I get “page not opened” & “cannot parse response”. In Chrome on my IPad it still works, but not in Safari. Did you hear of the problem and is there a solution/patch for?

Thanks in advance,
Siebe

Hi Sara,

Thank you very very much for this code.

I have made 2 esp8266 boards to control 2 relays each, total 4 relays.
I have assigned IP address A to board 1 and IP address B to board 2.
Those 2 boards are connected to my wifi router, and I access the IP A and IP B from my phone to control those relays.

Now I am setting up a third esp8266 board (say that the IP Address will be C) to become Access Point and Webserver to control another 2 relays.
I wish that board 1 and board 2 can connect to board 3, and expecting to see all 6 buttons when accessing board 3 through IP address C to control all 6 relays. So that I can get rid of the router.
All 3 boards are placed in 3 different location.

Would you please help me? I am still learning those html css and javascript but it may take few months untill I can write good code for this purpose.

Thanks

Javen

Hi.
For that, you need to use websockets.
You can use this tutorial as a reference: https://randomnerdtutorials.com/esp32-websocket-server-arduino/

Please add auto update code. Like Toggle switch pressed in one device automatically updates on other device.

Thanks and Regards..
