Error when using UHD, GRC

GNU Radio
1

Hi,

I installed latest UHD (on a WinXP SP3 OS) but when I’m trying to run
the uhd_find_devices.exe I receive this error:

C:\program files (x86)\uhd\bin>uhd_find_devices
Win32; Microsoft Visual C++ version 10.0; Boost_104400;
UHD_003.000.001-release

Device discovery error: An existing connection was forcibly closed by
the remote
host

– UHD Device 0

Device Address:
type: usrp1
name:
serial: 4bd1fd09

when I try the
uhd_usrp_probe.exe I receive the following error message:

C:\program files (x86)\uhd\bin>uhd_usrp_probe
Win32; Microsoft Visual C++ version 10.0; Boost_104400;
UHD_003.000.001-release

Error: An existing connection was forcibly closed by the remote host

Could anybody explain me why I’m getting this error?

I would like to ask a second question, maybe I don’t understand it well.

I installed UHD, GNURadio latest versions, Python and many dependencies,
but
when I’m trying to make a simple flowgraph in Gnuradio companion (a
Signal
source connected to a NULL sink) it says that I don’t have installed
grc_wxgui,
the error is:

Traceback (most recent call last):
File “D:\TestProjects\Test\top_block.py”, line 12, in
from grc_gnuradio import wxgui as grc_wxgui
ImportError: cannot import name wxgui

It means GRC when parsing schematic writes in source code that it
requires
wxgui, but WXGUI is not ported as I saw on joshknows.com.

Could anybody tell me what the problem could be?

Thank you very much.

Best regards,
Mark.

Weird MS error. Have not seen it before… I guess the OS is printing
that when you open UDP sockets? I would google around for it. Maybe you
have a firewall or something enabled. A wireshark capture might also be
helpful to show when the socket is barfing (if that is the case).

I never ported the wx gui sink support to the build system. You will
need to use QT. Choose the QT GUI option in the options block for your
flow graph.
