=== Addressed & Reliable Communication ===
More complex setup can used addressed communication and '''Reliable Datagram'''.
Addressed communication allows you to associate a unique identifier (an integer value) to each RFM69 module. This allows detect the sender when receiving a message on the frequency and to act properly.
'''Reliable Datagram''' do a lot of management with connection to make sure that the packets were received. You do not have have to send the acknowledgement in your code, the Reliable Datagram take care of it for you.
The '''RadioHead''' library contains the examples {{fname|RadioHead69_AddrDemo_RX}} and {{fname|RadioHead69_AddrDemo_TX}} that demonstrate the adressed and reliable communication. See the [https://learn.adafruit.com/adafruit-rfm69hcw-and-rfm96-rfm95-rfm98-lora-packet-padio-breakouts/using-the-rfm69-radio#addressed-rx-and-tx-demo-9-50 Addressed RX and TX Demo] on the Adafruit's learning system.
