Scripts and configuration snippets are stored in no volatile directory. /var/data/upload_wifi/

Step 1

so you need to create the directory first: mkdir /var/data/upload_wifi/

Step 2

Now we need to create scripts which will handle switching OFF and ON the WiFi AP, when the STA will connect and disconnect.

I have done this on Challenger LTE board link, which is RP2040 based.

You need to enable data serial at boot (boot.py), this is disabled by default. When the board boots you need to run file serial_passthrough.py the program.

Your computer will report new COM/Serial port. Use that to talk with the device connected to uart of the CircuitPython board.

Create files on CIRCUITPY

file: boot.py

To implement Cross-Origin Resource Sharing (CORS) on OpenWRT within Luci is actually simple.

After very long search, I have found code in uHTTPd on gitlab, which clearly shows option for CORS. I haven't found anything, which would describe how to actually configure it.

There is nothing in uHTTPd documentation describing this functionally, /etc/config/uhttpd does not mention anything either.

Luckily, you can have a look into how the process is starting and what parameters is checking.

Here is the start-up script, which in effect does check of 2 IP addresses

#!/bin/sh
#
# This script will be executed when PPP/WAN connection is established.
#
# Script for checking connection by two ping ip addresses
#
# Put checking ip addresses

Script reads BIN0 (binary input 0) on the Conel, SmartWorkx router and displaying it in a console. Can be looged in systemlog as well. Little modification can be done to log it into the file, in CSV format.
