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.
For default module settings, see the wiki page
https://github.com/jgromes/RadioLib/wiki/Default-configuration#sx126x---lora-modem
For full API reference, see the GitHub Pages
