      2    RadioLib SX128x FLRC Modem Example
      3 
      4    This example shows how to use FLRC modem in SX128x chips.
      5 
      6    NOTE: The sketch below is just a guide on how to use
      7          FLRC modem, so this code should not be run directly!
      8          Instead, modify the other examples to use FLRC
      9          modem and use the appropriate configuration
     10          methods.
     11
