/*
   RadioLib Si443x Transmit Example

   This example transmits packets using Si4432 FSK radio module.
   Each packet contains up to 64 bytes of data, in the form of:
    - Arduino String
    - null-terminated char array (C-string)
    - arbitrary binary data (byte array)

   Other modules from Si443x/RFM2x family can also be used.

   For default module settings, see the wiki page
   https://github.com/jgromes/RadioLib/wiki/Default-configuration#si443xrfm2x
