Happy new year!
Just to notify, my ethernet works fine -- I could use wired internet to
connect to the Internet.

This should return the Mac address and any ip address heard
Does a usrp. Ping ?

Thanks for reply.
It seems to be the problem of the promiscuous mode(broadcast&multicast)
of the ethernet card...I use wireshark to detect the packet transmission
between pc and usrp2 when it plugs in. Surprisingly find_usrps works and
both sent and received packets are detected. It looks that
Hi, this is my first message so hi everyone.
Well, at last i have my USRP (i got it yesterday), it works (a Flashing
green led is working, ok). But, looks like i can't "open" the usrp. Ok,
after search by internet it seems like it is an USB controller error (by
the way, seems to be the TYPICAL
Greetings,
Few months ago I started experimenting with using Qt and the gr-qtgui
component and I found it to be much easier to work with that wxPython.
I found the additional controls to be useful when they are needed but
they take up quite a lot pf vertical space. In the present
configuration th
Hi all,
Recently I want to implement a OFDM based multi-rate system, and I am using
benchmark_ofdm_tx/benchmark_ofdm_rx programs in ofdm directory. I know I can
use unlock/lock mechnism to disconenct/connect the exising blocks to change
modulation block, and it indeed works. However, I also notice

Hello,
I get a question about the half band
filter in the DDC. I found that the LO (local oscillator) in my
daughter board is set at 0.2MHz less than the carrier center
frequency, which means that the IF of the output signal is
Hello everyone, I must find a way to compile the FPGA project for the USRP2 to
continue my Masters. I use ISE 12.1
and the top project u2_rev3 in the repository
git://ettus.sourcerepo.com/ettus/fpga.git using all the files in different
makefile.
The compilation works well and I get the bin file
In GRC, I defined a message queue like below:
self.msg_q = gr.msg_queue()
It waits for the USRP transmitter, and read the message received in the USRP
receiver in the local machine, using the code like below:
m = tb.msg_q.delete_head()
But if there is no message sent. It seems t
Hi,
can anyone help me with how to perform spectrum sensing using energy
detection method using gnu radio and usrp.
Thanks and Regards,

Hi All,
I started working with GNURadio a few months ago as a platform for use
with a Visual Light Communication front end. I've had some good
success with the basic benchmark testing and implementation of a few
basic tests with GRC, but I'm curious as to what datarates have been
achieved w

You may want to print out sdev->get_time_now

Hi all, I want to use 8 bits sample. I use inband_2rxhb_2tx.rbf firmware. I
use set_format( ) set data format as width 8 bits and shift 8 bits
and the return true. But when I read data the data still 16 bits format. I
do not use gr stuff to read data, however I directly read data.
If I use 16 bits
Hi,
I am testing a transceiver link in ISM band using two USRP2+RFX2400, one
configured as TX and the other one as RX. I would like to test my own
FPGA program, so for now I have your FPGA codes in which I only changed
the signal driving the DAC in TX to be an square wave (+8191 or -8192)
