[Discuss-gnuradio] Benchmark_rx problems

[Pedro Sánchez Canal]

Hi, I'm trying to establish my first connection between two computers using two 
USRPs. As I have read, there are some example programs that allow you to do it 
in an easy way in order to understand the basics of gnuradio work. I have used 
Benchmark_tx and Benchmark_rx but I haven't had any success. The two computers 
are connected through a coaxial wire and I have also a oscilloscope connected 
between then to check if everything is ok. 

Benchmark_tx seems to work propertly with the next configuration:

python benchmark_tx.py -f 90M
>>> gr_fir_fff: using SSE
..................................................................
..................................................................
..................................................................
..................................................................
..................................................................
..................................................................
..................................................................
.......

In the oscilloscope screen I can see a sin wave so everything is right with the 
transmission point.

However, executing benchmark_rx I can't get any result and the program never 
dies. I have look over the benchmark_rx, receive_path and pkt codes and I can't 
find what is the problem. I've also tried with several frecuencies but the 
result is the same.

python benchmark_rx.py -f 90M

Could you help me please?? Have you got a detailed doc about how benchmark_rx, 
benchmark_tx, receive_path, transmit_path and pkt work???

Thank you in advance.

Pedro
