[Discuss-gnuradio] Problem with code changes in digital-bert for USRP2

[Srinivas]

Hi All:

I have made changes in the digital-bert folder of GNURadio-3.2.2 for my system to work with USRP2. I have been able to successfully transmit using the benchmark_tx.py script. However even after making changes in the receiving scripts (benchmark_rx.py & usrp_receive_path.py) on the same lines as transmit, I get the following error when I execute it:

gnuradio-3.2.2/../digital-bert>sudo ./benchmark_rx.py -f 2.4G

Traceback (most recent call last):
  File "./benchmark_rx.py", line 120, in <module>
    tb = rx_bpsk_block(options)
  File "./benchmark_rx.py", line 56, in __init__
    self._receiver =usrp_receive_path.usrp_receive_path(options)
  File "/home/winuser/gnuradio-3.2.2/gnuradio-examples/python/digital-bert/usrp_receive_path.py", line 63, in __init__
    self._setup_usrp_source(options)
  File "/home/winuser/gnuradio-3.2.2/gnuradio-examples/python/digital-bert/usrp_receive_path.py", line 83, in _setup_usrp_source
    self.u = usrp_options.create_usrp_source(options)
  File "/home/winuser/gnuradio-3.2.2/gnuradio-examples/python/digital-bert/usrp_options.py", line 80, in create_usrp_source
    usrpx=options.usrpx,
AttributeError: Values instance has no attribute 'usrpx'

My scripts are located in the following folder:

http://www.esnips.com/web/gnuradiodigital-bert/

I am working towards making all the scripts compatible with USRP2. I saw the introduction of "usrp_transmit_path" and "usrp_receive_path" wrapper functions in 3.2.2 and would be using the same for converting other applications (ofdm, sprectrum sense etc.)  as well.

Is there anybody else who is working on the same problem ?

Any help on this issue would be greatly appreciated.

Thanks
