At the current time, I don't believe that there is a way to do this,
however it has been discussed and is certainly planned for the future.
There is a discussion of supporting flowgraphs that allow TX/RX
switching, so I would expect the method for this to be similar.

AttributeError is a python error because the python module that you
are accessing does not have an object called "xyz" in it.  This is
probably unrelated to the HackRF and a problem with the xyz module's
python wrapper.  Maybe something in the swig file?

The osmocom block has the HackRF open, so other blocks won't be able
to access it directly.  What needs to be implemented is the ability to
send a retune command to the osmocom block and have it handle the call
to the libhackrf.
