The SX1231 module used on the breakout board can be used in 'raw Rx/Tx' where it modulates incoming bits (from pin #2) and sends them on the radio. In 'raw Rx/Tx' there is no error correction and no addressing. This mode is weak and error prone so it will not be covered.

Packet mode will be suited for almost 99% of use cases. When packetized, the code can setup a recipient for the data, ensure error correction (''data transmitted correctly''), automatic retries on transmission error and acknowledgement when the packet is delivered. In packet mode, you got a reliable data pipe, transparent communication without getting care about the complex details of data transmission over radio frequencies.
