Hi everyone,
The CGRAN upgrades are finally complete. After our server took a hit last
week, I figured it was time to upgrade some things while I fixed some
others. CGRAN is now using Trac 0.11.4 and subversion 1.6.0, with some
python and apache module updates in the background. This seems to h
To users having difficulty with the XCVR2450 daughterboard.
A bug was found that effects the XCVR2450 in transceiver applications,
especially tunnel.py. A fix has been applied to the host code in r10853
of the trunk. This fix is for XCVR2450 + USRP (does not apply to the USRP2).
Testers are w
Thanks a lot for the feedback. I got it to work eventually.

What I think is happening is that a pair of connected sockets is created

Hi all,,
I read the [Discuss-gnuradio] and know that gr.hier_block is gone in current
GNU Radio.

I used the command: svn co https://www.cgran.org/cgran/projects/bbn_80211/trunk

I checked out the bbn trunk and got
Hi all,
I'm upgrading the trac version that we are using for CGRAN and trying to
work out our internal server error. The CGRAN subversion server will not be
going down, but the wiki will be out of usage for a little while right now.
Thanks!

Hi all,
Since I have tested the tx code (bbn_80211b_tx_port2.py), I wanted to run the
bbn_80211b_rx.py inorder to capture the packets sent but I encountred this
error:
# ./bbn_80211b_rx.py
Traceback (most recent call last):
File "./bbn_80211b_rx.py", line 179, in

You want to probe the SMA connectors. The pins tx0-tx7 are digital
control lines. If you see any signal on the control lines, it is
probably very weak leakage from the DAC.

Haha, had exactly the same idea and posted it before reading your email.
Good to know we're on the same wavelength, though!

Should we try and put this on CGRAN?
I tried to contact the developer regarding some issues (specifically, that
gps-usrp doesn't compile with the latest gnuradio trunk), but got no
response.
