/*
  RadioLib Si443x Blocking 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.

  Using blocking transmit is not recommended, as it will lead
  to inefficient use of processor time!
  Instead, interrupt transmit is recommended.

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