RadioLib SX128x GFSK Modem Example
|
|
|
|
This example shows how to use GFSK modem in SX128x chips.
|
|
|
|
NOTE: The sketch below is just a guide on how to use
|
|
GFSK modem, so this code should not be run directly!
|
|
Instead, modify the other examples to use GFSK
|
|
modem and use the appropriate configuration
|
|
methods.
|
|
|
|
For default module settings, see the wiki page
|
|
https://github.com/jgromes/RadioLib/wiki/Default-configuration#sx128x---gfsk-modem
