More complex setup could used addressed communication and '''Reliable Datagram'''.

* '''Addressed communication''' allows you to associate a unique identifier (node id, an integer from 0..255) to each RFM69 module. This allows detect the sender when receiving a message on the frequency and to act appropriately properly.

* '''Addressed communication''', used here, allows you to associate a unique identifier (node id, an integer from 0..255) to each RFM69 module. This allows identifies the sender when receiving a message (on the frequency+AES) and to act appropriately properly and possibly send back a response. Addressed mode is suited when '''building a team of robot'''!

* '''Reliable Datagram''' do a lot of management with connection to make sure that the packets were received. You do not have to send the acknowledgement in your code, the Reliable Datagram take care of it for you.
