That was a typo. It should be -O plughw:0,0. Note the comma instead of
the period.

Hi,
When I have 2 SDR setup, I was looking to send some data/string like Hello
World from one of them and recieve it on the other setup. Are there any
scripts existing already? If not can I get some help on this?
Thanks for any and all response
Meenaktchi
I was about to ask a similar question: Has anyone implemented
a simple RTTY mode? I suspect keyboard to keyboard RTTY would
be the simplest possible Hello World type example.

I have a complex signal coming in from the USRP that I am filtering
and sending to a scope_sink. Now I wish to add a channel on that same
scope and output a square wave It seems like I can do it, I am just
having issues of figuring out how to do it.
Any suggestions?
Thanks

Indeed the float allows more than 2 channels. I will take a look at
the complex scope to see what needs to be fixed. You know I am
continually amazed by this software! I was just thinking how nice it
would be to have the magnitude displayed and BAM, complex_to_mag
presented itself.

Hi:
I have a question about CSMA example(tunnel.py):
Why does the default value of CSMA threshold set to 30dB? if it is absolute
value, I think it will be too high. Or is it the relative value to noise
level?
Thanks in advance for any comments!

When we send and recieve using USRP boards and GNU SDR, on the recieve side
usrp setup, demodulator connects to gr_correlate_access_code_bb which
connects to framer_sink. framer_sink pushes the assembled packets into the
target queue. Can we extract the pkt here to read the data? How can we send
Okay so actually coding this up, I'm still missing something. So
here's what I'm doing... and you'll see the hole.

USRP server gets the PING request and generates the RID, creates the
USB block, and fires it off to the FPGA.
USRP server then needs to associate

You can pack Hello World string as paylaod then use send_pkt(payload) on
the transmiter side. similarly unpack the payload at reciever to convert
into string.
you need to use same formating for pack and unpack at Tx Rx respectively.
I am assuming you are using packet radio.

I'm having a bit of trouble locating the passages of interest in the

look?
Thanks.
