I’m attempting to have my ESP32 generate a HTTPS Access Point connection. Can this be done with an ESP32?
I am using Platformio as my build environment running on a Raspberry Pi 4. I can re-create this with my Arduino IDE from my PC as well.
The source code can be found at the following github link: GitHub - tsbiberdorf/httpsConnection: Perform HTTPS connection from a Access Point with the ESP32
The code compiles and loads fine, but when I make the connection to my ESP32 from my WiFi device (my phone), the ESP32 resets with the following error message. I’m not sure how to debug into the library code.
Thanks.
