Re: [Discuss-gnuradio] Re: Help required tunnel.py

Did you manage to have an IP/TCP section working? I tried changing both the carrier threshold and interpolation, decimation values but every time I tried pinging the other USRP, I got the message 'Destination Host Unreachable'.

I tried benchmark_tx/rx and always had packet drops; benchmark_ofdm_tx/rx always had TIMEOUT. The only thing that worked for me was transmitting a sine wave using usrp_siggen and plot it using usrp_scope. I'm so confused. I've been trying to identify the problem for almost 2 weeks now but no avail.

If it helps, I'm running Ubuntu 10.04, GNU Radio 3.2.2 tarball. Hardware: USRP, RFX2400 daughterboards and WA5VJB antennas (the antennas are not from Ettus Research, but should work fine)

I did the same question a few weeks ago! You should change carrier threshold to a higher value, default is 30 db, I changed to 50 db to get a clear connection, I'm working with openSUSE 11.1 and I'm root user transmitting in first wifi channel, so I write in console:
user# python tunnel.py -f 2412e6 -c 50

Good Luck
