This is a reworking for Raspbian release 'bookworm' of part of the AutoHotspot functionality that derives from RaspberryConnect code AutoHotspot-Installer on GitHub.
The functionality is focussed on providing a Wireless Access Point (WAP) if, when the network comes online, there is no connection to a local network. This happens at boot time.
There is a configuration file that defines the SSID, Password, and Network, of the WAP. This file can be updated via a web browser using a companion package canpi-web-app-ssr running on the Raspberry Pi.
Building and installation instructions are in INSTALL.md
