Re: GNU Radio Ressources

Hi Abu,

sorry for the delay in getting back to you, but: What's the thing you need to simulate 
specifically?


If you need to get a headstart we really just freshly overhauled 
https://tutorials.gnuradio.org , which ideally should give you all the skills you need to 
build your own simulations!


Best regards,
Marcus

Hi everyone,
I hope this email finds you well,

I need some resources about gnuradio to prepare for my Master thesis which is about 
SDR-based image transmission in a simple DAC communication channel using USRP-2920 as 
hardware and GNU Radio Companion as Software on Linux Mint as OS.


I need just a simulation of a simple DAC digital communication channel to understand more 
about the GNU radio components (if there are explanations of each component, I'd also like 
that).


Happy to hear from you soon,
Have a nice day!

Re: building OOT module in conda

[Ryan Volz]

Hi Wayne,

You shouldn't need specifically gnuradio=3.8.2 for gr-lora_sdr (despite what 
their README says), and that fails because there was no gnuradio-build-deps 
package at the time of that release. Try it with gnuradio=3.8 instead.

You do need gnuradio-build-deps installed into your "gnuradio" environment and 
not "base" (exception: you've installed gnuradio into "base" and just want to 
just that, which I generally don't recommend).

The necessary compiler package is installed by gnuradio-build-deps, so no need 
to install cxx-compiler.

Finally, yes, run CMake on the OOT with the "gnuradio" environment active so 
that it has everything it needs.

Cheers,
Ryan

Re: building OOT module in conda

[Wayne Roberts]

yes that works fo me.
The reason i had this trouble initially is the CondaInstall on gnuradio
wiki says to activate default environment prior to running cmake.
So, i can compile it now with gnuradio environment activated.

But this OOT module includes posix header files sys/resources.h and
sys/syscalls.h, which arent available on windows, so it seem it would be a
porting job to run this OOT in windows.

thanks for your help!

Re: GNU Radio Ressources

[Abu Baraa]

I will explain more. I need to make two softwares which interact with
each other by sending data (E.g: image, video,...) using GNU Radio
Companion. The first is the sender and the second is the receiver which are
composed by GNU Radio Blocks to build a communication channel like the
following:

1/ (Sender): Signal Source -> (Modulation, Encoding, Filtering...) ->
Antenna.

2/ (Receiver): Antenna -> (Demodulation, Decoding, Filtering...) -> Sink.

Briefly I am looking for ressources, examples of communication channel and
documentation about gnu radio blocks. I have already finished with the GNU
Radio tutorial that you sent me.

Thank you in advance,

Have a nice day Sir,

Re: building OOT module in conda

[Ryan Volz]

Hi Wayne,

I think I see where the confusion occurs in what the wiki says, so I've just 
made some edits to hopefully make it clearer.

It does look like some porting would be necessary for gr-lora_sdr, 
unfortunately. Sometimes it's possible to use IFDEFs and substitute in the 
appropriate Windows thing, and sometimes more substantial edits are necessary. 
I always have to turn to Google in these cases. Good luck!

Cheers,
Ryan

It looks like gnuradio is installed via conda with environment gnuradio

But its not clear if gnuradio-build-deps needs also be installed with 
the active environment set to gnuradio vs base.
Also cxx-compiler installed in which environment.
And then finally, running cmake on the OOT module in the same

Getting the USB driver installed for any device is always going to 
be an external step that no GNU Radio package can help with, but if the UHD 
documentation is not getting you there then I recommend giving the generic 
WinUSB driver a try as documented here:

Ah, GR 3.8 might be a little trickier since the Wiki documentation 
has been updated to correspond to 3.9/3.10. That said, nothing about that OOT 
looks like it would necessarily make the process more difficult.

VS2017 might be necessary, or at least have the "MSVC v141 - VS2017 C++ 
x64/x86 build tools (v14.16)" component selected for inclusion in your Visual Studio 
installation.

 > Also note that in conda, cmake and git are not installed by

Something seems off here since `mpir` and `cmake` should both be 
installed in an environment where `gnuradio-build-deps` and `gnuradio-core` are 
installed. `git` is not required for the build, only for how you're getting the 
source, so it would be necessary for you to install the `git` package manually.

Let me be explicit about how I think this should work:

1) Start from an activated base conda environment:

      conda activate base

2) Create a new environment, say "gnuradio", that contains 
`gnuradio` and, since you want to build an OOT, `gnuradio-build-deps`.

      conda create -n gnuradio gnuradio

wavfile source block issue

[Alejandro del Hoyo Vijande]

Good afternoon,

My name is Alejandro. A few days ago I run into a problem when trying to
use the wav file source block. I am unable to find either "wav file soruce"
or "wav file sink" blocks among the GNU Radio default block library. I read
online that this issue could be related to the dependencies installed in my
laptop, but after running the "sudo apt install" command for the
dependencies that were missing the problem was still there... Apart from
this, my console shows no errors when running the scripts. Also, I am able
to see the .cc and .h files related to this block inside gr-blocks
directory. What else can I do?

I hope someone could help me with this.
Thank you all in advanced!


Best regards,
Alejandro.

what version of GNU Radio do you have, and how did you install it?
