Hello everyone,
I want to create 2 relatable Apps.
The first one should send a text and other one should receive that text.
While the other one received that Text, an animation should appear.
Can anyone help me??
Thanks

Is it must to make an own server for that? can't we connect 2 devices just with Bluetooth client or Bluetooth Low energy?

Unless you're 50 meters away from the person you're planning on chatting with (keep in mind that this estimate disregards any obstructions that may disrupt the connection), you might find it hard to do so.
This is why Taifun's example uses a server.
This is not really a server, this is only a name of a component...
to have a connection between 2 devices one is considered the client (the one who is requesting a connection) and the other is the server (which is accepting a connection...
What about trying the example?
