When esp12 is powered ... in wifi stations appear your wifi module . For example for my module i set name to "Jersinio" with few lines codes in Arduino ide:
WiFi.mode(WIFI_AP);
WiFi.softAPConfig(apIP, apIP, IPAddress(255, 255, 255, 0));
WiFi.softAP("Jersinio");
Connect with your wifi ( Jersinio)...
After you can acces your index page with a name domain , for example "Jersinio.it" (not need to insert the 192.168.4.1, but functioning )
For rispond a your name domain you need to set these code lines:
dnsServer.start(DNS_PORT, "jersinio.it", apIP);
......................................................................................................................................
Only few lines and now you can acces your wifi module in an modern mode with a name domain.
I create a html page index.htm wich can download files to esp12
You can download the surce code for arduino ide from here :
Also you can upload any file you want in esp module...
You can see a list of files uploaded in esp12 with command:
