What sdr are you using?
I am trying to use usrp b200 and I was not able to make it work. I have
read the research paper wrote by sylvain but that's for the old code.
Is there anything or any other hardware that I could use? I have a b210
b200 bladerf x115 and a limesdr full board. I don't want to spend any money
on the cube dongle and usrp1 are not made anymore.
Any suggestions would be appreciated.
