      2    RadioLib SX128x Settings Example
      3 
      4    This example shows how to change all the properties of LoRa transmission.
      5    RadioLib currently supports the following settings:
      6     - pins (SPI slave select, DIO1, DIO2, BUSY pin)
      7     - carrier frequency
      8     - bandwidth
      9     - spreading factor
     10     - coding rate
     11     - output power during transmission
     12     - CRC
     13     - preamble length
     14 
     15    Other modules from SX128x family can also be used.
