RadioLib SX1231 Blocking 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.
|
|
|
|
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
|
|
|
|
