Code works not with WIFI AP / is it Possible ?

[HolzCoder]

Yes, I have created a programme here with sections from my program which is roughly the same as mine.
I have attached the programme.

GPIOViewerWithAP.zip

I am going to give it a try to see how to make the library compatible

Hey, thanks for the answer.

ok i didn't realise that the ESP needed internet access. my system is independent and self-contained without internet access. The system should work stand alone. Then it probably doesn't work with the GPIO Viewer. but thanks for your efforts anyway.

I will have to modify the library to support this, can you give me an example on how you setup an access point, so I can test it on my side

[thelastoutpostworkshop]

when I try your code without GPIOViewer library, I am unable to connect to the server using the softAPIP address printed, which is 192.168.4.1 on my network. Normally my esp32 connect to 192.168.1.xxx when using WIFI_STA

I don't know very well the WIFI_AP_STA mode, is there anything I am missing ?

[thelastoutpostworkshop]

I just read that 192.168.4.1 is the default, I can change it with IPAddress local_IP(192, 168, 1, 1);
IPAddress gateway(192, 168, 1, 1);
IPAddress subnet(255, 255, 255, 0);

ok now I understand how it works, I was able to connect to the Wifi of the ESP32.
But it will not work with the GPIOViewer be cause it requires internet access, the web application is hosted on Github pages.

Internet Sharing (Not Straightforward): For devices connected to the ESP32's AP to access the internet, the ESP32 must be configured to route traffic between its Station interface and AP interface. This requires setting up NAT or similar routing configurations, which is quite complex and not directly supported by standard Arduino libraries.

Do you have internet access with your ESP32 setup as an access point ?
