      2    RadioLib CC1101 Receive Example
      3 
      4    This example receives packets using CC1101 FSK radio module.
      5    To successfully receive data, the following settings have to be the same
      6    on both transmitter and receiver:
      7     - carrier frequency
      8     - bit rate
      9     - frequency deviation
     10     - sync word
     11 
     12    For default module settings, see the wiki page
     13    https://github.com/jgromes/RadioLib/wiki/Default-configuration#cc1101
     14 
     15    For full API reference, see the GitHub Pages
