I am working with ESP8266 device with Arduino . So my requirement is .....Once I programmed the ESP as a open Access point ( Not sure it can be done ) then every one can access ESP . Once some one long in to the ESP, he shows the web page of our school advertisement
Please advice if it is possible
Please note that in this scenario we should not use Routor and Internet access
It will work, I've done it. The problem you will have is storing the web page and remember you will not be able to use server side applications like PHP unless you can compile it for the LX106 processor or Arduino.
Basically, it's easy if you only store static web pages but a real pain if you want to update the pages or run dynamic content.
You are perhaps looking for an implementation of a captive portal, which means that your local stored webpage (within ESP) will appear before any user selected page. This project seems to be doing that:
