Benchmark files

I would like to know the best way to test the and files.

These files are located in the /usr/share/gnuradio/examples/digital/ofdm

My goal is to transmit a jpg file from one USRP 2 device to another one
and have the jpg file saved on the host computer.

I am using Ubuntu 14.02 with GNUradio.

I run this command on the transmitter:

sudo ./ --from-file=F.jpg -f 2.4e6 -m qpsk -a

F.jpg is saved in the /usr/share/gnuradio/examples/digital/ofdm

I also edited line 105 of the from:

data = - 2)


data = open(‘F.jpg’).read()

At the receiver I run the following:

sudo ./ -A RX2 -f 2.4G -m qpsk -a addr=

At then run a packet capture
on the host computer that is connected to the receiving USRP and I see
that there are many packets being received, but I never see the file.

Each USRP is connect to a separate computer running Ubuntu. The USRP
devices have the default IP on them of

Can someone please tell me the best way to run the benchmark code? Do I
need to do some synchronization? If so how?

Many thanks.
