Hi All
I am tried to run bbn802.11 , but I faced the following error,

root@ala-laptop:/sdr/douggeiger/src/examples# ./bbn_80211b_rx.py
Traceback (most recent call last):
File “./bbn_80211b_rx.py”, line 37, in
from bbn_80211b_pkt import *
File “/sdr/douggeiger/src/examples/bbn_80211b_pkt.py”, line 32, in

from bbn_80211b import *
File “/sdr/douggeiger/src/examples/bbn_80211b.py”, line 46, in

class bbn_80211b_mod(gr.hier_block):
AttributeError: ‘module’ object has no attribute ‘hier_block’

I am using ubuntu 8.04,USRP1, Gnuradio 3.2.2 which work properly
I checked old discussion , but I couldn’t find the solution.
any suggestion please

It looks like you have the version of the bbn code that was not
converted over to the hier_block2 API (which is required in GNURadio
3.2.x). Where did you get your copy from?

Hi
I got my copy from
https://128.2.212.19/browser/projects/bbn_80211/branches/douggeiger

I installed usrp2_version by running
svn co
https://128.2.212.19/cgran/projects/bbn_80211/branches/usrp2_version/
but I am got the following errors.

root@ala-laptop:/sdr/bbn/gr-bbn/src/examples# ./bbn_80211b_rx.py -f
2.437G -v -b

return _gnuradio_swig_py_runtime.hier_block2_swig(*args, **kwargs)
RuntimeError: Hierarchical blocks do not yet support arbitrary or
variable numbers of inputs or outputs (usrp_rx)

dose urrp2_version works with usrp1 ?where can I find USRP1 version
converted over to the hier_block2 API.?
Best regards,
Alaelddin

Hi：
I have the same error!!
It says "Hierarchical blocks do not yet support arbitrary or
variable
numbers of inputs or outputs
（usrp_rx）"when i ran the bbn_80211b_rx.py.
And i’m using usrp2.
Do you fix the problem now? If yes,then how did you fix it?
Hope to have your response soon!Thank you so much!
