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
