AIRSPY_TOOLS .... whats is it?

Ruben Navarro Huedo (EA5BZ)

Hello friends:
I am having lots of problems with rx_tools ( I can't enable BIAS-T and some other stability problems.
I want receive (and save) fm with my raspberry and also IQ (if possible).
I have been reading about Airspy TOOLS ( )
What is it? can it be used like rtl_fm and rtl_sdr (record FM and IQ) ?
Any other option to do it with Airspy?
Thank's a lot.
