Good day.
Task: write an application on Android that will raise the Wi-Fi access point with the specified parameters.
Then, a device (a home-made reader of something) will be attached to this point, which will transmit information via the http protocol, which must be received and put into the phone (tablet) in any format.
I would be very grateful for any farewell or help. All the best.
If necessary, I can clarify the information
