/*
RadioLib LR11x0 LR-FHSS Modem Example
This example shows how to use LR-FHSS modem in LR11x0 chips.
NOTE: The sketch below is just a guide on how to use
LR-FHSS modem, so this code should not be run directly!
Instead, modify the other examples to use LR-FHSS
modem and use the appropriate configuration
methods.
For default module settings, see the wiki page
https://github.com/jgromes/RadioLib/wiki/Default-configuration#lr11x0---lr-fhss-modem
For full API reference, see the GitHub Pages
https://jgromes.github.io/RadioLib/

\brief Initialization method for LR-FHSS modem.

\param power Output power in dBm. Defaults to 10 dBm.
\param tcxoVoltage TCXO reference voltage to be set. Defaults to 1.6 V.
If you are seeing -706/-707 error codes, it likely means you are using non-0 value for module with XTAL.
