STA or AP mode browser unable to connect to ESP8266-12

I'd like my IoT device to power up in a state where the user need only type 192.168.4.1 into the browser to gain access to a web page that would enable them to enter their ssid and p/w to gain access.

This is only possible if connected to the ESPs AP

OK - let me try to explain a possible way how to manage this:

• ESP can not connect to a AP, so ESP offers his own AP and starts a http server to receive a SSID and Password to connect to over simple html form offered by that server.

• Take a smart phone, connect to the ESP APs and open a browser to connect to 192.168.4.1 and enter SSID and Password. sample page

• Now ESP tries to connect to that given AP and if connected saves that information and stops his AP and http server

Is this what you are thinking of ?
