Actually, I mostly see u0 (which I believe is usrp overruns). However, I did receive 2/3 packets. Dola On 4/4/07, Greg Troxel <[EMAIL PROTECTED]> wrote: I think you should see real data packets at 1 Mb/s if there are any. I would expect multicast in IBSS mode to be like this. -- Greg Trox

Could you explain more precisely what you are doing, and what happens? I have run the code under NetBSD with modified tap(4) driver that handles 802.11 in addition to Ethernet. I am not clear on the state of 802.11 support in the Linux tap driver. -- Greg Troxel <[EMAIL PROTECTED]> __

2007-04-04 Thread Dola Saha
Hi, I am using gnuradio with BBN's 802.11 mac in Ubuntu platform. When I am using bbn_80211b_rx.py, I cannot capture any packet. But, when I am transmitting using bbn_80211b_tx.py, I can capture all the packets as transmitted by the transmitter. Has anybody faced this problem? Thanks and Regar
