-   This example receives packets using RF69 FSK radio module.
-   To successfully receive data, the following settings have to be the same
-   on both transmitter and receiver:
-    - carrier frequency
-    - bit rate
-    - frequency deviation
-    - sync word
+  This example receives packets using RF69 FSK radio module.
+  To successfully receive data, the following settings have to be the same
+  on both transmitter and receiver:
+  - carrier frequency
+  - bit rate
+  - frequency deviation
+  - sync word
 
-   For default module settings, see the wiki page
-   https://github.com/jgromes/RadioLib/wiki/Default-configuration#rf69sx1231
+  Using blocking receive is not recommended, as it will lead
+  to significant amount of timeouts, inefficient use of processor
+  time and can miss some packets!
+  Instead, interrupt receive is recommended.
