you are right stinky about the rephrasing:
ok, this text files includes all bluetooth devices that are in range at the moment.
these bluetooth addresses will stay in the file until the next time that I press the search button in order to search for new devices.
I want to show in a graphical way that: at 2.14 pm this file has 3 addresses in it, while in 2.30 pm the text file has 5 addresses in it (after a new search)
how am I supposed to do that?
