RadioLib SX123x Blocking Transmit Example
This example transmits packets using SX1231 FSK radio module.
Other modules from SX123x family can also be used.
NOTE: SX123x modules offer the same features as RF69 and have the same
interface. Please see RF69 examples for examples on AES,
address filtering, interrupts and settings.
Using blocking transmit is not recommended, as it will lead
to inefficient use of processor time!
Instead, interrupt transmit is recommended.
For default module settings, see the wiki page
https://github.com/jgromes/RadioLib/wiki/Default-configuration#rf69sx1231
For full API reference, see the GitHub Pages
