Bbn 80211b usrp2_version problem

Hi, everyone,

I just got two set of USRP2 and want to test it using the bbn 802_11b
usrp2_version. I use the example scripts: bbn_80211b_rx.py and
bbn_80211b_tx.py.

I use the default setting: on one machine: ./bbn_80211b_rx.py and on
another
machine: ./bbn_80211b_tx.py

The tx script work correctly. The console print the packets it send. But
for
the rx, it can not received any packet, just print out the “S” letter?

Does anyone meet such problem? Thank you very much.

Best,

Chen

I think that is a buffer overrun. In otherwords, your computer cannot
process the data fast enough.

Yes. This might help.

“At a decimation rate of 4 you are generating 25 MS/s. If those samples
are
complex shorts, that works out to 100 MB/s. If those samples are
complex
floats, that is 200 MB/s. In the former case, you really need a RAID
array
of at least two fast drives to keep up. In the latter, you’re going to
need
to do something more exotic.”

This was in a previous post.

Hi：
I’ve been doing the same things recently. But I wonder if there is
a
bbn_80211 usrp2 version? I know this object from its official
website:https://www.cgran.org/wiki/BBN80211. And I don’t see anything
about
usrp1 version or usrp2 version.
So confused about this, looking forward to your answer! Thank u so
much!
Still ,what ubuntu version and gnuradio version do you use? I 've
spent too much time on the software environment thing.
Again,thank u so much!
