E4000 and Gnuradio installation problems.

[Benoit]

Hello

I read very often the message in this group but now it's my turn. ;)

I'm already my E4000 dongle on windows with HDSR works great. But I would like to use is on my laptop who is under Debian.

I used 2 sites to try to install E4000 and Gnuradio

http://sdr.osmocom.org/trac/wiki/rtl-sdr

http://superkuh.com/gnuradio.html

First i've try to do all was mentionned on http://sdr.osmocom.org/trac/wiki/rtl-sdr. When i do as mentionned "rtl_sdr /tmp/capture.bin -s 1.8e6 -f 392e6 ".

I get :

n3b@laptop:~$ sudo rtl_sdr /tmp/capture.bin -s 1.8e6 -f 392e6
Found 1 device(s):

Tuned to 392000000 Hz.
Reading samples in async mode...
Short write, samples lost, exiting!

Library error 0, exiting...

o_O

When I lauch gnuradio-companion and i try to load a flowgraph. I get a huge amount of errors (posted on pastebin http://pastebin.com/dZedA5i1 ).

After that I thought i didn't installed well components. So i went on the other website (http://uperkuh.com/gnuradio.html) and I use the script wrote by patchvonbraun.

wget http://www.sbrac.org/files/build-gnuradio
chmod 755 build-gnuradio
./build-gnuradio --verbose

After I try again to lauch gnucompanion but I still have some errors. I don't remember how many things I did to try to setup the dongle and the software, but too much. Could you help me?

A problem with python for the flowgraphs?

When i open multimode.grc (https://www.cgran.org/browser/projects/multimode/trunk). I get messages (http://pastebin.com/UCfsUnGf) but the flowgraph is open.

Exiting Gnu Radio build/install

[Heath Hunnicutt]

The output from rtl_test looks normal.  Therefore, your e4000 chip (and the dongle) are working.

My dongle usually works, but I sometimes get the same error message.  This may happen if I bump the dongle.  Is there a way to plug your dongle into a cable, to ensure a firm connection?

Otherwise, the problem may be related to USB somehow.  Perhaps you are using a USB hub?  How have you connected the dongle?

Are there other USB devices on the same bus?

[Benoit]

Thanks for your answer.

Usb dongle are pluged directly to the computer, no hub at all. I should try an other port.

If someone have an answer for my bugs (logs posted below).

;)

[Heath Hunnicutt]

I imagine lots of people can help you with your build errors.  ;)

As long as you experience "short read" using the widely used rtl_sdr, various programs won't work well for you.  Be sure to solve that error message before you try to use the device.

[Random Walk]

Might it be possible that instead of loading a flowgraph file, you are trying to load an HTML page that has a flowgraph in the HTML for the page, with all the (HTML code necessary to format it.)

If that's the case, you want to extract the XML and ONLY load that. HTML may look a bit like XML but they are two separate beasts.. completely.

If you can go to the web site you downloaded the flowgraph and try to get it in its raw XML form, that would be best. For example, on github, there is a selection at the bottom "download in original form" or something like that.

You'll probably find that when you do that, the examples will work, but if you get other errors, at least they will be real, challenging errors and not artifacts of downloading the container for the flowgraph and not the flowgraph itself. If there is any issue, you can use a simple text editor like MS notepad or pico or even the Linux cat command to see what's in that file.. Either way, it should be a markup language, which is just text..

To illustrate, this is HTML.. the language web pages are written in - for your browser.. this is NOT what you want to load into GRC:

<!DOCTYPE html>
<html>
  <head prefix="og: http://ogp.me/ns# fb: http://ogp.me/ns/fb# githubog: http://ogp.me/ns/fb/githubog#">
    <meta charset='utf-8'>
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
        <title>gnuradio-grc-examples/receiver/fm_rx.grc at master · csete/gnuradio-grc-examples · GitHub</title>
    <link rel="search" type="application/opensearchdescription+xml" href="/opensearch.xml" title="GitHub" />
    <link rel="fluid-icon" href="https://github.com/fluidicon.png" title="GitHub" />
    <link rel="shortcut icon" href="/favicon.ico" type="image/x-icon" />

This is what you want:

<?xml version='1.0' encoding='ASCII'?>
<flow_graph>
  <timestamp>Wed May 23 14:43:03 2012</timestamp>
  <block>
    <key>options</key>
    <param>
      <key>id</key>
      <value>fm_rx</value>
    </param>
    <param>
      <key>_enabled</key>
      <value>True</value>
    </param>
    <param>
      <key>title</key>
      <value>FM Receiver</value>
    </param>
    <param>
      <key>author</key>
      <value>OZ9AEC</value>
    </param>
    <param>
      <key>description</key>
      <value>Simple FM receiver prototype</value>
    </param>....

And so on...

[Benoit Mio]

Oh great, thanks a lot.

 

I will check my *.grc with your advice.

 

Can someone tell me if my approach it's correct ?

• Plug the dongle
• Run sudo rtl_sdr /tmp/capture.bin -s 1.8e6 -f 392e6
• Start Gnuradio-companion with a good flowgraph (without errors)
• Build/start it?

Am I right?

 

Thanks a lot.

 

Benoit

Hello

 

And for my other problems with

Someone post and answer on reddit.

So I readily admit that I don't know everything, but looking at the error, it seems that parts of your Python installation are having problems with Unicode files. Unicode, unfortunately, still has a bit of corner cases and such... are you by chance a multilingual person? If you can find a way to cludge it to get it pas this error (try changing /usr/lib/python2.7/posixpath.py to not have any Unicode characters in it maybe) this may well pass and be fine... this appears to be only occurring in a part that is generating documentation that you may well never need, or can find elsewhere, or focus on working at a different time.

You only need to do this if you want to store capture data in a file. If you
want to use GNURadio to listen to live radio, you don't need to run rtl_sdr.

> * Start Gnuradio-companion with a good flowgraph (without errors)

Here is a good example that got me started:

http://ebrombaugh.studionebula.com/radio/gnuradio/index.html

> * Build/start it?

If you have installed everything you need (GNU Radio, gr-baz, etc.) then the
above flow graph will work fine.

Cheers,
Adam.

[Random Walk]

The flow graphs are just for designing an application. Once you have it working you can run the python file it generates (and not run GRC at all.)

Does that make sense? The flowgraphs are the design phase, the python apps are the run phase.

Hello Random

The python as to be in the folder of the grc to get loaded?

I've edited the ./build-gnuradio script and removed all doxygen mention to don't install this package. It's doc file so I don't need it I think.
The ./build-gnuradio runt well... yeah

I dreamed enough

It's work now !!

I simply follow
RTL-SDR @ BackTrack 5 R2 www.hack4fun.eu/2012/05/rtl-sdr-backtrack-5-r2/

I think that GR-baz was missing, I did again the installation of RTL-SDR and GR-baz.

Awesome. Thanks for your help. Hope my feedbacks will help people.

gqrx is a lot easier to use than GRC if all you want to do is listen and not design a radio, although you need gnuradio installed before you can build gqrx, so probably wouldn't have helped in this case.

[Benoît Mio]

Thanks

I will test it.
