[LR1121] set high frequency fail.

[klabshowroom]

I am trying to use high frequency as:
int state = radio.begin(2050.0, 250.0, 10, 7, RADIOLIB_LR11X0_LORA_SYNC_WORD_PRIVATE, 10, 9, 0);

and the response is as:
failed, code -8

is there anything wrong for my setting?

Hello!

From

https://jgromes.github.io/RadioLib/group__status__codes.html

... we can see that Error-8 is Invalid Bandwidth.

From

https://www.semtech.com/products/wireless-rf/lora-connect/lr1121#documentation

... or from the Radiolib source code, you can see that the 2.4 GHz radio uses LoRa BW values that are different from the values that we are accustomed to using for most LoRa hardware.

Hope that helps!
