I'm using my ESP32-S2-WROVER-I and I try to implement both station and accesspoint mode. Default should be stationmode and after a certain amount of connection attempts with default SSID and password I want my stationmode to turn off and turn on accesspointmode. In accesspointmode i want to provide a html page in which you can determine SSID and password
after defining SSID and password it suppose to switch back to stationmode and repeat my procedure if SSID and password still do not match any nearby routers.
Now I'm not sure how I can implement this procedure. I'm using the https "simple" example as a template. my init function for my station mode looks like this:

}Now 2 Questions arose.
1: How can i include my main.c file within the connect.c file ?
#include"main.c" didn't work.
2: Is this approach even a good approach? im not really sure. It feels like a provisionally solution for my problem. Does someone else got a more efficient approach ?
thanks in advance!
