/*
   RadioLib SX128x Transmit Example

   This example transmits packets using SX1280 LoRa radio module.
   Each packet contains up to 256 bytes of data, in the form of:
    - Arduino String
    - null-terminated char array (C-string)
    - arbitrary binary data (byte array)

   Other modules from SX128x family can also be used.
