Help using UCLA Zigbee PHY examples updated for UHD

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:

      mahboob@ubuntu:~/gr-ieee802-15-4/src/examples$ ./uhd_cc2420_rxtest.py

      cordic_freq = 2.475G

      data_rate =  2M

      samples_per_symbol =  2

    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
