1ª- Is it necessary to put the cc1101 in reception or transmission mode? Since in the basic examples of transmission and reception I do not see that in any case it is executed in one mode or another.

2ª- The code that I present is very simple, and before going crazy I must say that I am a relatively new user of Arduino, especially in RF, so I imagine that I must compress the audio signal that I have at the input to be able to send it, I understand that the Maximum buffer of the module is 60 kbps, I can't find much information about this, could anyone give some guidelines for doing this?.

3ª- Can the audio input be connected directly, or perhaps through programming, to any pin of the cc1101 module so that it emits bareback? I don't know if it can be done, it's an idea, but maybe it would simplify the transmission and reception, although I suppose this module is made to be controlled with a mcu.

Audio input: direct output from the smartphone. Audio output: amplified with a small egg speaker. MCU: Arduino NANO. Pins: Arduino - CC1101. Gnd-Gnd 3.3v-3.3v D6-GDO0 D10-CSN D13-SCK D11-MOSI D12-MISO1 D2-GDO2

This is for testing, to verify that the code works.

The project is only recreational, nothing professional, any suggestion is welcome :).

PS: Sorry if I missed something, I'm new to the forum.
