I was curious if anyone has tried this before or has any idea how difficult it would be to accomplish. I'm wondering if there is a way through a touch screen or LCD and keypad combination to set the wireless access point and password through some sort of menu on the LCD and touch.

I.e

1. Scan for wifi access points and display them on a LCD or Touch Screen
2. Select your wifi access point and type in the password
3. From this point on, this access point and password is saved into the ESP until it is reconfigured from this same menu.

Is this possible to do and if so has anyone done anything similar to this before?

Many thanks my friends. You guys rock.

But what you want is doable.

From what I've read, the ESP8266 can apparently be programmed to act as an access point, from which you can connect to with a phone, and access a simple web server where you can from there program the access point and password that the esp will use in the future. Can you or anyone else confirm that this is infact true?

Thanks a lot atexit and to anyone else who decides to share their input.

One of those is WiFiManager from @tzapu :

In fact, you can build you own page if you wish, simply emulate the "AT+CWLAP" (from the crappy AT Firmware) using the WiFi.scanNetworks() function API in the case of Arduino framework, or wifi_station_scan() in the case of native SDK.
