Matt,
There was a frequency offset of ~30 KHz at the Rx w.r.t Tx so I
compensated for it and it worked!.
The settings I am using is as follows:
./benchmark_ofdm_tx.py -f 2.45G --tx-amplitude 0.9 -M 8 -s 200 -m bpsk
--fft-length=512 --occupied-tones=80 -i
That formula will give you the number of occupied tones per second. You
need to multiply by the number of bits per tone to get bps. If you are
using BPSK, multiply by 1. If using QPSK, you'll need to multiply by 3,
8PSK by 3, etc.
I meant to say:
BPSK - multiply by 1
QPSK - mult by 2 (not 3
Well I am pleased to say that the txrx_wbx.bin firmware
from Jason's git seems to work on my USRP2 - WBX combination.
These SD cards are strange, I have two identical SD cards
same manufacturer (Kingston) size etc. One works and one does
not on the USRP2. On both cards the USRP2 lights come on
Hi,
Did you put a static IP address in your Ethernet?
Tip, put any dummy static IP address, and you will find your USRP2!!!
Best Regard,

I had tried that. Didn't help!
Thanks though.

Hi,
I have a similar problem in my code.
I modified benchmark_tx.py from gnuradio-examples/ofdm and ofdm.py
from blks2impl so that I can change the number of active subcarriers
on fly.
In the packet sending loop of benchmark_tx I periodically do the following:
lock the top block (tb.lock()), cal
