I want to transmitted digital file (i.e. .jpg) with file source on Tx side
then received the file with file sink.
It's not about silence or noise because I use access code from packet
decoder, the problem is when I start the Rx's fg the file sink immediately
write file output even Tx's fg not run.
Hi Surya,
I use access code from packet decoder
That sounds like a good approach; you should have told us earlier!
Problem is when I start the Rx's fg the file sink immediately write
file output even Tx's fg not run.
this means that the access code checking doesn't work.
Best regards,
Hello everyone,
I try to transmitting a file using PSK modulation with 2 x USRP B200 as Tx
and Rx. When I run the Tx's fg, the Tx only transmitted before the Rx fg
completely run. But when I run the Rx's fg, the file sink already write
something before I run the Tx's fg. Is there any way to both
Maybe use a squelch block and wait for for received power to exceed
some critical level? Or use timed events?

I've never used timed events in gnuradio, I just know that you can do
things in a time-aligned way. You may want to google for gnuradio
