      2    RadioLib SX126x Channel Activity Detection Example
      3 
      4    This example uses SX1262 to scan the current LoRa
      5    channel and detect ongoing LoRa transmissions.
      6    Unlike SX127x CAD, SX126x can detect any part
      7    of LoRa transmission, not just the preamble.
      8 
      9    Other modules from SX126x family can also be used.
