Android Question p2p client to client (one to one) application

[avnersh]

Hello,
I want to develop an app that establishes a connection between only two phones. That is, a one-to-one connection. None of the users is defined as a server. The apps transfer small text files between them in JSON style.
Of course, there needs to be a process for one client to invite another to a dialogue.
I’m looking at various options and I’m searching for the simplest and most immediate solution. Can anyone help with some initial guidance?
Thank you
