Hi all,
I am looking to disable the loopback of power on the RX while the
RFX2400 is transmitting.
From what I understand, to do this I use set_auto_tr(). Do I need to
enable it for both the TX and RX descriptor?
What i do with the TX descriptor does not seem to matter, my application
will still work properly and the power is looped back through the RX.
When I set the RX descriptor, the transmitter works but the receiver
completely breaks. The only raw sample values I ever get are a mix of 0
and 1.
I'm using homegrown C++ dboard code, that matches up with the python code:
https://moo.cmcl.cs.cmu.edu/trac/cmu_sdrg/browser/dboard_code/db_flexrf_mimo.cc#L232
http://gnuradio.org/trac/browser/gnuradio/trunk/gr-usrp/src/db_flexrf.py#L321
Is my understanding of how this works incorrect?
Thanks!
George
