I wonder if SBX board can replace all RFX series including 2.4G ISM band and
so on.
And currently I tried to use RFX2200 with GRC
but it says RFX2200 is unknown (0x002d)
How can I solve this problem?

Yes, but they do not work with UHD which is the only way to use my USRP N210

Common dude, you have been around on this list for a while now. Post the
verbose from whatever you are running, or even better, post the output
of uhd_usrp_probe.

Hi all,
When a user run into problems, it seems to me, that user will post to the
gr-list *help: it doesn't work*
even if the problem has been solved 100 times before.
When I run into problems (not a GR guru) I browse the archives first
https://lists.gnu.org/archive/html/discuss-gnuradio/
and
Not a good example but a start...

Jeremy those shorts are little endian indeed, I guess Vincenzo is

Hello all,
Currently I am testing a modified version of tunnel.py, but I am seeing some
strange results. My modifications were essentially a re-factoring to prepare
for future additions, however somehow I was able to receive a transmitted
packet on the same USRP that transmitted it.
The USRP tran

I just pushed a branch with UHD versions of the OFDM apps:
git://github.com/bistromath/gnuradio.git
It's in the uhd_ofdm branch. This is untested code, so use at yo

Hi everybody,
I want to announce a new project on CGRAN dealing with analysis of
unencrypted and encrypted wireless keyboard transmissions using the
Logitech 27 MHz technology.
With the realized project, the air interface of wireless 27 MHz Logitech
keyboards can be captured and sensitive da
Lets say you have a GUI app that has a fixed runtime determined by a
head block set to (sample_rate * n_seconds). Currently, the gui keeps
running. Is there an OnShutdown or some function I can override to catch
the flowgraph completion? Worst case, can I set up a loop thread to
check tb.is_running
Oh, my problem is the same with yours: I want to change transmit frequency
according to the sensing result from rx side. I tried lock() and unlock() but
cannot work.
I solved it by creating 2 flow graphs for tx (to transmit files) and rx (to
sense the channel) sides separately and call start(),

You know that you can change frequency at any time, right? You don't
have to lock the fl

Absolutely! As long as the underlying hardware supports full-duplex
operation.

Would you like to expand it in detail or refer me to some places I can look
for? Dose this need 2 antennas on 1 daughterboard? It would be great if I can
build a graph with rx path and tx path and run 2 paths simultaneously.

My mistake. I do change frequency while the transmit graph is running. The real
problem is the rx side (sensing) and tx (transmitting) side cannot run in the
same time (my rx and tx is realized with receive path and transmit path in one
top block). So I first run the rx to sense, then stop it an

Yes, you'll need two antenna,

Thank you for sharing this, Matthias. It looks like excellent work!
I didn't realize that Logitech had introduced AES-128 in any of the 2.4
GHz products. The non-Bluetooth 2.
Got it. I will try it out. Thanks!

Hi,
I'm trying to implement 2x2 MIMO systems using four USRP2s, two of which are
connected by MIMO Cable and only one USRP2 is connected to computer through
ethernet.
After I look through the related discussions and document on the website. As
far as I know, the SD card for USRP2 connected to c
