+   RadioLib SX126x Transmit Example
+
+   This example transmits packets using SX1262 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 SX126x family can also be used.
