Forum: GNU Radio Terminal commands

Hi,

I have constructed the attached file on my grc
<http://gnuradio.4.n7.nabble.com/file/n40037/09.png>

I want to transmit the typed message over the air from one antenna and
receive it through other antenna(both antennas belong to the same usrp.)

I need help in knowing the set of commands i need to use on my terminals 
to
actually see the transmitted and received messages.

Thanks.

Hi Manjusha,

what you most propably want to do is something of the like
# ncat -l -u 12346
to see what your deframer spits out.

To see what your transmitter is going to transmit, you should
use whatever software generates the data and sends it to port 12345.
Presuming you're using the ubiquitous bash, you can use something like
# ncat -u 12345 < mylovelettertognuradio.txt

Three Notes anyway:
1. That data will be binary. If you don't input bytes that map to
"readable" characters, you won't see much meaningfulness on your 
terminal.
2. Transmitting and receiving simultaneously on the same daughterboard
is tough, to be honest. The crosstalk is most propably stronger than
your reception. Be warned.
3. Is UDP really the protocol of your choice in both cases?

Happy Hacking!
