RadioLib SX1231 Receive Example
This example receives packets using SX1231 FSK radio module.
NOTE: SX1231 offers the same features as RF69 and has the same
interface. Please see RF69 examples for examples on AES,
address filtering, interrupts and settings.
For default module settings, see the wiki page
https://github.com/jgromes/RadioLib/wiki/Default-configuration#rf69sx1231
For full API reference, see the GitHub Pages
