[Discuss-gnuradio] Last few packets dropped

[Zheng Zeng]

Hi all

        When I ran benchmark_ofdm_tx.py, I noticed that the last few packets 
(5-20, depends on the packet size and modulation) always got dropped. The 
spectrum analyzer shows nothing transmitted. Using --discontinuous helps to 
reduce the # of dropped packets, but the 2-3 packets of the last run still got 
last. 

        Similar case when I run tunnel.py under the example ofdm folder. When I 
ping another machine, spectrum analyzer shows no transmission at all although 
the laptop screen shows "Tx: len(payload)=42". 

        I searched the mailing list and found similar discussion two years ago 
about the dropped packets problem but no solusion there. Has anybody 
successfully got tunnel.py working? 

        My OS is Ubuntu 7.04 and I checked the gnuradio several days ago. I use 
USRP1 and RFX2400. Thanks!
