This is sample code not yet complete.
when Wifi connected need to close the softAP.
maybe some dns with ESP8266mDNS.
test with password test192.168.4.1 and enter your ssidKanin Peanviriyakulkit @DogRocker
If you can take todo, all help are welcome :)

I need to add "WiFi.disconnect();" after line 181, and it works fine with ESP-01!
Thx
Can you tell me how to clear the eeprom in ESP 12E.
its missing to empty esid in declaration
String esid="";
Man... U code not working!!!
Many erros!
Fantastic. Very nice. Thanks for sharing
I get "Not found: /setting" when I enter my ESP's IP address and '/setting' after the address. There's no SSID or Pass stored in it. It connects to WiFi as shown in the screen shot attached. What do I have to do to be able to enter WiFi credentials through the web browser, so I can reboot ESP with WiFi credentials from it's EEPROM?
Very useful sketch. It works very well :)
I'm having just a problem with the serial monitor, because I can't see anything it should print during the execution.
Do I need a particular version of the Arduino IDE or to do some setting?
thanks
I have a litle question, When the code reads the EEPROM it always shows '?' (question marks) within the console Do you know what seems to be the problem?
Thanks in advance.
@diegoiacono you should select 115200 baud rate.
code working but need to add "WiFi.disconnect();" after line 181
Thanks for your code. It's like paracetamol for me now.
nice work, but i cant see the AP after starting. There is no test ssid or something.
I think i do something wrong, any help?
Thanks in advance.
Any idea about FreeRTOS to store the ssid and password into eeprom.
Nice All is working.
change the line 122 " if ( webtype == 0 ) " and line 169 else if (webtype == 1) and
add "WiFi.disconnect();" after line 181
Thank you so much....:)
Why does the SoftAP is named as Demo and its insecure (with no password) ?
I was expecting the ssid and password would be test and test !? has anyone experienced this ?
very good! It has its own perks. but I've been expecting which way to combine that code and static IP address.
Hi, just tested your code. It will always try to connect with the WiFi irrespective of credentials are stored or not. Checking the length of esid is wrong. It will always return 32. Simply checking if esid != "" works fine.
Hi, @NetForces. Sorry for late response. I have no time to do this script now.
You should try https://github.com/tzapu/WiFiManager, The author alway update his libs and fast response.
