I'm looking for a solution for configuring wifi in headless mode, the same way as IoT devices : when not known wifi in range, toggle to AP mode with a predefined SSID, run a small web-server to list available network, and provide inputs to enter network Key.
I didn't find anything, so I'm eager to develop something to solve the problem.
So does someone know a premade solution ? If not, how should I proceed ? Write a script that modifies wicd/wpasupplicant config files ?
