I'd like to be able to configure a Raspberry Pi to work as a wifi access point that loads an interface where users can choose the WiFi network to connect to. I've read the guides on how to make an access point, but I need the access point to load a webpage (once connected to the pi) that displays the current wifi networks and the option to connect the raspberry pi to that network. After I make the pi an access point, what else do I need program for this to be possible? Do I need to create my own web server (Apache) and code a webpage to configure the wifi networks?
I'm currently using Rasbian, and if you're interested in the use case for this, I plan on putting a few Raspberry Pi's around a location to send Bluetooth data to my servers (RSSI, UUID, etc). I'd like to be able to connect all these Pi's to the wifi network using my phone, tablet, etc.
Thanks for your help.
