Thanks for your reply.
Actually I need the human triggered function in GnuRadio but I just do
not know how to do that… thanks for your help.
If you took Gnu Radio and radios out of the picture, and the question
was "how do I trigger something to happen when I press a certain key on the
keyboard, or press a button of some sort?" is solving THAT problem
something that is easy for you? If the answer is a decided NO, then
you may need to gain more experience in general software design FIRST
before wandering into the abstruse disciplines of signal processing
and radios.
if the answer is instead "not a problem, I already know how to do that",
then I suggest that you spend some time with the Gnu Radio tutorials.
it should come as no surprise that Gnu Radio, being what amounts to
just a specialized programming environment, hasn't necessarily already
come up with everything you might want to do in a nice tidy package.
Some programming will be required.
From your e-mail address I assume that you're a student. it may not
have occurred to you this early in your software career that the set
"useful things someone might want to do with a computer" and "useful
things someone might want to do with radios" are very very large
(if not infinite) sets. Which means that from a practical
perspective "some programming will likely be required" is almost always
the answer.
I've cross-posted to discuss-gnuradio because there may be an audience
there who have already done something similar to what you want and
may ask more clarifying questions.

*主题:*Re: [USRP-users] Is there a "trigger" in GNURadio with USRP?
It depends on what sort of latency you need in the trigger. Given that
it is human triggered I’m guessing fairly sloppy.
If it could be a keyboard key and you don’t need microsecond scale
latency, then this is all doable in software/GnuRadio and you should
probably post your question on the discuss-gnuradio mailing list since
an implementation of this would be largely independent of radio hardware.

Hello everyone.
I am using USRP N210 and Gnuradio 3.7. I want a “trigger”like a
button that only when I push the button then the USRP start to
transmit the sample from file source. I did not find any materials
or experience from other about this case.
The reason I want to do this is that the transmission is
correlated to the human motion so I need to control the timing.
Is there anyone know how to implement this fuction?
Regards,
Kevin
