PLUTO SDR TypeError: 'Context' object is not callable

There is a known issue with the python bindings from libiio.

Can you try downgrading pylibiio first by running:

sudo pip3 install pylibiio==0.21.0 --no-binary :all:

Do you have another application like IIO-Scope running alongside pyadi?

ls -ls d.dat
