[Discuss-gnuradio] Installation on Ubuntu 12.04 LTS
it's probably not stuck, it's just that after that point, it goes off and uses apt-get to load all of the pre-requisites, which can take a *long* time, and is done silently, unless you use the --verbose option. Thanks! That was the case. -- Regards, Smith ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

[Discuss-gnuradio] Subject: Re: USRP testing plesae help
You may have a version mismatch between the installed python modules in lib and installed python scripts in bin. Either that, or its a very old bug. Whatever the case, I recommend you nuke your gr install(s) and grab a recent release. First of all bundle of thanks. Last post did help me alot. I installed a fresh gnruadio 3.4.0. Connected the USRP1 and usrp_probe ran successfully. Both the boards were detected. :) When I tried to connect DBSRX2 to RXB or RXA the it wasn't detected. I mean when I ran usrp_probe the model shown was 'unkown' and frequency range was from -900.0 to 9.00. Any help what I need to do in order to check the DBSRX2 ? 2) Also I got N210. How can I test it. Please help. Waiting for a quick response as I am worried. Any help in this regards is highly appreciated. What do you want to test? If you want connectivity, install UHD and the command uhd_usrp_probe will tell you all the USRP devices connected to your pc: http://code.ettus.com/redmine/ettus/projects/uhd/wiki If you want to test signal integrity, configure gnuradio with gr-uhd support. There is a very basic signal generator and analyzer display that comes with the component. uhd_siggen_gui.py uhd_fft.py I believe. Or make a quick flowgraph in gnuradio-companion :-) == I downloaded UHD from link above, then I did following. cd UHD. cd host mkdir build cd build cmake ../ make make install ldconfig But then when I ran uhd_find_devices I got following output: Ignoring discovered device RuntimeError: Expected protocol compatibility number 9, but got 7: The firware build is not compatible with the host code build. No UHD Devices Found Lights D and F are on the N210. No other lights. Another question what is minimum speed required for LAN(Etherenet) interface on PC ? 100Mbps or 1000Mbps ?

Re: [Discuss-gnuradio] Subject: Re: USRP testing plesae help
Thanks for the response, I did sudo make and sudo make install when I was installing the UHD. My UHD folder is in my home directory. Sorry, I am not getting you with your last post because I am not very good at Linux. Any help further is highly appreciated.

Re: [Discuss-gnuradio] Muliple top_block()
Thank you very much all for such clear explanation of things. Actually I want to implement the coded OFDM. And was trying to figure out how can I run the trellis-encoder and OFDM flow graphs together. Your posts did help me a lot :).

But, I want to know that whether this type of thing is conceptually right or not ?? It is functionally correct, as you noted, but using GNU Radio this way is not very common except perhaps in automated QA code. Typically, flowgraphs run continuously, with data being injected into the graph via one or more sources and being removed via one or more sinks, and don't get started and stopped or re-run except in response to some application level event (like startup and shutdown, or for flowgraph reconfiguration). I think your use case would be better served by connecting your two flowgraphs using a message sink and a message source that share a common message queue, or even merging the two together, but it is hard to say without more information about what you are trying to accomplish. I read that there must be only one top_block(). Please guide me in this.. Having more than one top block is fine since release series 3.3, but requires more attention to detail as you have to use the start()/stop()/wait() sequence on each instead of the simpler run().

Re: [Discuss-gnuradio] Muliple top_block()
Hi Thanks for the reply. I used tb1.start() and tb2.run() and I think that is working. The two blocks don't have connections with each other. The flow is like: tb1=gr.top_block() 1. tb1.start() 2. Some variable declaration... Repeat step 3 and 4, five times 3. A function that creates tb2 and runs it and return the result --- tb2=gr.top_block() --- vector source---convolution coding-destination --- tb2.run() --- return destination.data() 4. send the result to the tb1 for processing 5 . tb1.wait() As far as the result is concerned it seems right.

Hi everyone, I want to implement convolutional coding using the trellis block. I don't want to use any modulation scheme or anything else after the encoder. The flow graph I want is shown below vector sourcetrellis encoder viterbi or any decoder---sink Part of the code is shown below src_d = (1,0,1,0,0,0,1,1,0,0,1) sorc = gr.vector_source_b (src_d) //source encoder = trellis.encoder_bs(f,0)//encoder s2f= gr.short_to_float() dec=trellis.viterbi_s(f,len(src_d),0,-1) //decoder dst = gr.vector_sink_s () //sink tb.connect (sorc,encoder,s2f,dec,dst) return(dst.data()) When I run the above flow graph I get nothing just empty, ( ), list. I am using awgn1o2_4.fsm file. I got the correct result after encoder. I can't use the trellis.metric or trellis.viterbi_combined_X to implement decoder as I am not using any modulation :( .

[Discuss-gnuradio] benchmark OFDM Question
Hi everyone,
I am working on OFDM in gnuradio. I ran the benchmark_ofdm.py file.
Everything worked well, I want to ask one thing that I didn't see the last
packet on the terminal.
I set the packet size to 400 bytes and total number of bytes to be
transmitted to 1600. I should see 4 packets but i see only 3 packets. Where
is the problem??
Portion of the code is given blelow:
nbytes = int(1600 * 1) //line that I changed
n = 0
pktno = 0
pkt_size = int(400) //line that I changed
while n nbytes:
pkt_contents = struct.pack('!H', pktno) + (pkt_size - 2) * chr(pktno 0xff)
send_pkt(pkt_contents)
n += pkt_size
pktno += 1
-
Output is shown below:

gr_fir_ccc: using SSE
