[Discuss-gnuradio] benchmark files

[Adeyin Amon Ikpah-Aziaruh]

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

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

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 ./benchmark_tx.py --from-file=F.jpg -f 2.4e6 -m qpsk -a addr=192.168.10.2

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

I also edited line 105 of the benchmark_tx.py from:

data = "" - 2)

to:

data = "">

At the receiver I run the following:

 sudo ./benchmark_rx.py -A RX2 -f 2.4G -m qpsk -a addr=192.168.10.2

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 192.168.10.2

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.
