RadioLib SX1231 Transmit Example
|
|
|
|
This example transmits packets using SX1231 FSK radio module.
|
|
|
|
NOTE: SX1231 offers the same features as RF69 and has the same
|
|
interface. Please see RF69 examples for examples on AES,
|
|
address filtering, interrupts and settings.
|
|
|
|
For full API reference, see the GitHub Pages
