Hi William,

thank you very much for your answer. I don’t really like Linux
because it has many problems. As I’m writing you this message I’m
installing Ubuntu on a VirtualPC, everything was OK, but when files were
copied to the Virtual drive it gave me a BIG error, some I/O error while
copying, so this is what I’m talking about, many problems and is very
slow compared to Windows.

Anyway I will try to install some older versions, maybe I will have 

some luck to install it.

I would like to make the biggest part by myself, not using LabView 

or Matlab and neither Linux. What I would like to do is to use Windows
environment, to install GNU Radio, emulate python in a OOP environment,
meaning -> execute scripts in a software and get out data. I don’t want
to use USRP and GNU Radio to see waveforms (only at the begining when I
will try it out and when I will write the script), I want to transfer
data, to communicate with other wireless devices, etc. I want to use it
in the practical side to transfer data, if I could get 2 bytes of data
from a wireless device using microcontroller it would be heaven. This is
the hardest part, to transfer my first byte of data, after tha I could
make some nice things, nice systems.

Thank you very much for your answer and I would be very happy to 

receive any idea from anybody.

Best regards,
Sam E…

Sam,

Coming from a Windows user, I have to say that switching to Ubuntu was

  1. extremely easy and 2) greatly accelerated my understand and ability
    to use GNURadio/USRP - mainly because I could use the GRC, which is a
    Labview-like graphical interface to GNURadio and USRP.
    I’d highly recommend giving it a shot first, at least to learn with,
    before trying Windows development.
    That’s my 0.02. YMMV.

Also check out the Simulink libraries - I think they’re linked from
Ettus.com

Hi everybody,

I would like to ask some questions regarding USRP. I really need 

some help. I got my USRP with a WBX and LP0410. I work on a computer
running Windows XP. After I read many thing about how to install the GNU
Radio in Windows environment I could install it using MingW.

I used the gnuinstall.py python script like many others but when I 

tried to run my first script in python I got an error message
ImportError: No module named gnuradio. I don’t know what is the problem,
the gnuradio is installed, the latest one GNU Radio 3.3.0.

Could anybody help me with some ideas, how to make it work, and what 

I’m missing.

The second question would be. I would like to use the GNU Radio for 

a real application. I want to make a .NET application with Delphi Prism
and to be able to get data from USRP an set data. There are many
informations out there to emulate python (there are even DLL files) to
be able to run python scripts from a .NET application. What I want is to
exchange data with some devices running on 2 ISM bands (433 and 868). I
will make an application with Visual Studio 2010 and I would like to be
abel to read data through python script, interprete data and display in
the form as some value or a therometer showing the value sent by a
device. Wireless devices will have ASK, OOK modulation, some simple
stuff. Anybody have made something like this and could help me to start
it, I’ll make all the work but I need some help from those who already
made something like this.

Do you have any other idea how could I implement this, what other 

solution do exists? A alternative would be to use LabView but there are
problems, too. No documentation or some help. It would be very good to
have some DLL files that would implement functions and interface to the
USB data, but even if I was searching for a long time, I couldn’t find
anything.

I'm opened to any suggestion, because right now I'm stuck, I don't 

have any idea.

Thank you very much for any idea. I wish everybody a nice day.

Best regards,
Sam E…
