So far found ways to set up a VNC server with the local network. However, I'm looking for a way to create a hotspot that bridges a wifi connection on the pi and host a VNC server (such as RealVNC) or some sort of screen sharing application over the hotspot.
Then, I could have virtually any mobile device or pc connect to the hotspot and view the contents of the screen through the localhost in a browser (while all other traffic would be passed through connected wifi).
In essence, my goal is to share the contents of the pi 4 screen over a direct connection with a client device. Would this be possible?
And if so, would I need some sort of wifi adapter/dongle to bridge wifi to a wifi connection, along with additional programs to handle internet traffic?
