ESP8266 Community Forum

is it possible to configure the ESP8266 to start in AP mode, you connect to it's network, start a browser and then it displays a page with SSID and Password of the network you would like it to connect to, it then attempts to connect to that network and if successful connects if not switched back to AP mode. Could be a lot more useful than having to plug in the programmer every time you'd like to change wifi networks.

You could save the configuration to the internal or external memory and read this in before setting the AP mode in setup()

I wrote a Lua script to start web server, and an Android App to Post SSID and password to it. You need NodeMCU firmware though.

this works
