Hello,

I am having some communication reliability problems with
'benchmark_tx/rx.py' files. I came to know that these files are outdated
and one should use 'ofdm_txrx.py' instead. As 'ofdm_txrx.py' uses sync
words unlike benchmark files (or modules connected to
'benchmark_tx/rx.py'), I hope it will work better. But I could not find on
the internet how to use 'ofdm_txrx.py'. However, I found 'qa_ofdm_txrx.py',
that demonstrates the its use.
Since I am using USRPs, I want to connect 'ofdm_txrx' to 'uhd' and
therefore I modified 'qa_ofdm_txrx.py'. I replaced vector sink in the class
'ofdm_tx_fg' with 'uhd_transmitter' from und_interface.py, which internally
creates uhd sink. Now when I execute 'test_001_tx', I do not see any data
being transmitted on uhd_fft.

How can I get this to work? Am I missing anything?

Some details: I am using USRP N310 at 2.45GHz and 1MHz bandwidth(I get
overruns if I use higher bandwidth).

Thanks in advance.
