/* KiteLib SX127x Transmit Example This example transmits packets using SX1278 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 SX127x family can also be used.
