Hello all,


I have been trying for some time now to run your code uhd_cc2420_rxtest.py with little success on USRP N200. I am using gnuradio 3.5 and Ubuntu 11.10. I get the messages and error below:

      address@hidden:~/gr-ieee802-15-4/src/examples$ ./uhd_cc2420_rxtest.py

      linux; GNU C++ version 4.5.2; Boost_104200; UHD_003.003.000-25f0bd5

      cordic_freq = 2.475G

      data_rate =  2M

      samples_per_symbol =  2

      -- Opening a USRP2/N-Series device...

      -- Current recv frame size: 1472 bytes

    tb = oqpsk_rx_graph(options, rx_callback)

     File "/usr/local/lib/python2.7/dist-packages/gnuradio/gr/hier_block2.py", line 50, in __getattr__

    return getattr(self._hb, name)

   AttributeError: 'gr_hier_block2_sptr' object has no attribute 'chan_num'


Has anyone successfully run this on USRP N200 instead of N210? The file I am running is attached.

Hope to have help soon
