Re: [Discuss-gnuradio] How to get PlutoSDR Sink and Source into Gnuradio in Linux Ubuntu 17.04

[Ed Troy]

I am coming to the conclusion that gnuradio with pluto is simply not compatible with Ubuntu 17.04. I see that 17.1 is out. Perhaps I will try that. Otherwise I will have to try going back to an earlier version.

The gr-recipes folder is where you should find it! :)

In the VM

Does the .lwr recipe exist for gr-iio?

Did you remember to run the setup_env.sh?

I’m not sure what to say at this point.

Start from absolute scratch?

I can delete and install gnuradio, and gr-iio on my Ubuntu 16.10 Desktop and VM, using PyBombs. Pluto gets installed.

No, the VM has connectivity. I opened Firefox in Ubuntu VM and it works fine.

The notebook might have great connectivity. But if it’s not passed through to the VM, it would result in the “unable to fetch error” you reported.

What could cause that? I just confirmed that the notebook has internet connectivity.

It looks like that error occurred because your PyBombs doesn’t a connection to download gr-iio?  “Unable to fetch”

I tried this on another computer running Ubuntu 17.04 within VMWare that gives me the same problem. In this case, I did not need sudo and got slightly different results, but still no luck.

Lets blow away the gr-iio you have in there and start from scratch.

Try:

$ cd ~/prefix/default

$ source setup_env.sh

$ pybombs remove gr-iio

$ yes | pybombs recipes add gr-recipes git+https://github.com/gnuradio/gr-recipes.git

$ sed -i 's/gitrev.*/gitbranch: master/' ~/.pybombs/recipes/gr-recipes/gr-iio.lwr

$ pybombs install gr-iio

Please try these instructions and if any give you an error, post that.

gnuradio-companion gives me:

My setup is under ~/prefix/default

Actually, I had tried that earlier and it did not work. When I do it, after pybombs install gr-iio, I get
PyBOMBS - INFO - PyBOMBS Version 2.3.2
ByBOMB.install_manager - INFO - Phase 1: Creating install tree and installing binary packages:
PyBOMBS.install_manager - INFO - No packages to install.

After starting gnuradio-companion, if I search for pluto, it does not find anything

Something is wrong, but I don't know what.

Ed,

You installed using PyBombs? Perfect, that’s what the instructions call for! :)

When using PyBombs and installing new modules, you want to ensure you are under the proper prefix.  This is usually ~/gnuradio/default or ~/prefex/default (as per https://www.gnuradio.org/blog/pybombs-the-what-the-how-and-the-why/)

Additionally, make sure to run the script that ensures both PyBombs and gnuradio components are installed in the correct locations.

$ cd ~/prefix/default  (or ~/gnuradio/default)
$ source ./setup_env.sh

So get a grip on this, then run:

$ sed -i 's/gitrev.*/gitbranch: master/' ~/.pybombs/recipes/gr-recipes/gr-iio.lwr

$ pybombs install gr-iio

Let me know if it’s a win.

Cheers,

Blake

Hi Blake,
I saw that, and some other things, but I am wondering if that will work in my case since I installed Gnuradio-companion using PYBOMBS. I believe that results in a totally different directory structure, but I am not sure.

Hello Ed,

Located on the post you mentioned, at: https://www.rtl-sdr.com/adalm-pluto-sdr-unboxing-and-initial-testing/

Is a link to a reddit post explaining what you ask: https://www.reddit.com/r/RTLSDR/comments/6tnjba/getting_started_with_adalmpluto_and_gnu_radio/

Steps 2 and 3 of that post explain how to install the newest version of the gr-iio module (that includes Pluto support).

Cheers,

Blake

I am trying to get my PlutoSDR to work with Gnuradio-companion in Ubuntu 17.04. It took a while, but I have Gnuradio-companion up and running and if I go into the Industrial IO, I see various sinks and sources for FMCOMMS, but nothing for PlutoSDR. I have seen several posts where the PlutoSDR source is clearly in Gnuradio-companion. How do you get it into the software? One page that clearly shows the source is https://www.rtl-sdr.com/adalm-pluto-sdr-unboxing-and-initial-testing/.

I am running GNU Radio Companion 3.7.12git-269-g8aa965c6

Below is a screen shot of what I am trying to get from the above-mentioned web site.
