Hi,

I keep searching for 3 days on how to interface my new RF board with  
GNURadio, is there a guide documentation on how to create source sink  
blocks as an interface to my RF board with GNURadio companion. I already  
have a firmware running on my board, and need to create these  
source/sink  
blocks to understand this firmware.

Thanks

–  
Best regards

Hello Ayman,

generally, you just write a GNU Radio block with zero inputs (==source)  
and one with zero outputs (==sink) and let them communicate with your  
hardware.  
If you’re new to GNU Radio, reading the guided tutorials from  
[gnuradio.org](http://gnuradio.org) should get you started pretty fast.

Best regards,
