Is it possible to interact via wi-fi devices on iOS/Android?

Question

Android

There is a physical table in which a wi-fi module will be built in, you need to set up data exchange with it using the application. The table will send data to the server.
Question: is it possible to establish a connection with it using iOS / Android?
Is it possible to measure signal strength? For example, if there are several tables, then determine the nearest one.

Answer 1

Yes, all this is possible. The built-in tools are hardly enough, you have to teach them how to use the table protocol.
