Raspberry Pi - Auto WiFi Hotspot Switch - Direct Connection
A script to allow the Raspberry Pi to connect to a know wifi router or automatically generate a Non Internet Access Point if no network is found. You can then use SSH or VNC on the move and switch between the hotspot and home network without a reboot.
This is suitable for the Pi Zero W & Pi Zero 2 which have no LAN port or anybody who does not need an internet routed access point on a Raspberry Pi 3, 3B+ or 4. Just for direct Wifi access to the PI when you are out and about.
