Hi Josh,
I do not think there is a command line input for any channel line. The input
parameters are these;
mahboob@ubuntu:~/gr-ieee802-15-4/src/examples$ sudo
./uhd_cc2420_rxtest.py --help
linux; GNU C++ version 4.5.2; Boost_104200; UHD_003.003.000-25f0bd5
Usage: uhd_cc2420_rxtest.py [options]
Options:
-h, --help show this help message and exit
-a ADDRESS, --address=ADDRESS
Address of UHD device, [default=addr=192.168.10.2]
-A ANTENNA, --antenna=ANTENNA
select Rx Antenna where appropriate
-c FREQ, --cordic-freq=FREQ
set rx cordic frequency to FREQ
-r DATA_RATE, --data_rate=DATA_RATE
-f FILENAME, --filename=FILENAME
write data to FILENAME
-g GAIN, --gain=GAIN set Rx PGA gain in dB [0,20]
If I run the script with parameters, I still get the same error
mahboob@ubuntu:~/gr-ieee802-15-4/src/examples$ sudo
./uhd_cc2420_rxtest.py -c 2.45e9 -g 20

cordic_freq = 2.45G
data_rate = 2M
samples_per_symbol = 2

AttributeError: 'gr_hier_block2_sptr' object has no attribute 'chan_num'
Also there is no parameter chan_num in the python script. I am also assuming
the error is not emanating from the UCLA zigbee PHY since others have
successfully used it and besides the same script worked on the USRP N210 as was
posted on the mailing list.

Looks like a pretty strait forward error. There is no chan_num attribute. So
what class is "self" and why is it missing chan_num? How does chan_num get
initialized?
Perhaps there is a command line option you are not passing, and there isnt any
input checking/sanitation, so the error falls all the way through to this part
of the code.
