+  RadioLib RF69 Receive with AES Example
+
+  This example receives packets using RF69 FSK radio module.
+  Packets are decrypted using hardware AES.
+  NOTE: When using address filtering, the address byte is NOT encrypted!
+
+  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
+  https://jgromes.github.io/RadioLib/
