I'm working on a remote car to use outdoors. I'm controlling motors with relays using a flask webapp running at localhost. I can access the webapp when raspi is on my home network, by loading it's ip:port. Now I want raspi to work as a wireless access point or something so that I can connect to it's network and load the webapp in mobile browser. Can you please explain how can I go about doing that? So basically I want raspi to act as a server and any device with access can load the page in webbrwoser.
