Hello,
The USRP2 has a high data rate and it needs a lot of resources, I don't
think that it is a good idea to run both USRP2's on one machine.

Hello,
I don't encounter this problem anymore. Someone else was trying to
debug the code.
I tried to run both USRP2's on one machine with 2 gigabit ethernet
ports. It did not seem to work.
Does anyone know if it is possible to run both USRP2's on one machine?
Thanks,
Miklos Christine

Hi,
I do not encounter this problem, the simple_mac run in a correct
way for me. Do you use the latest versions of the firmware and fpga?

Hello Ben,
When I try to run the version of simple_mac that you posted, I
get an error.
It seems like an infinite loop that prints to stdout:
2nstreams:
It happens at the call to fg.rxpath.start() .
Do you have the same problem?
Thanks,

Hi all,
I modified the gain in the bbn_80211_rx.py file from 46 to
27 and
the loss ratio has fallen down to 15-20%. Do you have any idea
about the best value to put?

Hi all,
I succeeded to make the simple_mac.py working. now it's
pinging correctly but with a huge loss ratio. At first I
disabled the carrier sense functions but after I
reactivated
them but I'm not sure these functions are working. I
attached
the 80211_mac folder so any suggestion or amelioration is
welcome. I used this command line to run the python file:
./simple_mac.py -S 8 -v
I also hard_coded my mac adress so you need to change it
before use.
you can see here the results that I have obtained by ping:
