Hello,
I'm working on project in gnuradio, in which I'm trying to toggle on and off
the transmission from the USRP. After much research, I learned this was done
by tagging the first sample of a transmission with "tx_sob" and the last sample
with "tx_eob" (there was also a "tx_time" tag, but I found the former option
more convenient). I wrote a custom block that periodically tags segments out
of continuous stream of data as a proof of concept; however, the transmission
remains continuous as if there were no tag. I've checked with the tag
debugging block to ensure my block acutally generates tags. My flow graph is
simply: file source(repeat)->custom tagging block->psk mod->multiply const->uhd
sink.
Reading in the archive, I haven't found reference to success much success with
the streaming API. I would love the community's input on this problem.
Thanks,
Nathan
