Thank you for your advice, because of your advice, i install gnuradio and companion properly. But the problem is still remained, i could not realize how can i modify my old code with flow graph. I already saw your recommended codes, ieee802_15_4_oqpsk_phy.grc, transceiver_OQPSK.grc and .py files.

1) when reporting pybombs problems, please turn up the verbosity with "-v -v -v" 2) it sounds like your git cache is somehow incorrectly configured. How did you configure it? Does it exist? Again, verbose logging is your friend. On Aug 9, 2015 4:59 PM, "Andrew Neale" wrote: > Greetings, > I am t

Greetings, I am trying to install the latest gnuradio using pybombs. I am running linux mint on an amd64 machine. Here is the terminal output, basically it just keeps repeating the same thing, and then finally kicks me back to the prompt: office:~ > cd pybombs office:~/pybombs > ./pybombs insta

Re: [Discuss-gnuradio] USRP tuning time

2015-08-09 Thread Marcus Müller
Hi Mat, the answer is a bit more complicated, I'm afraid: so first of all, we need to distinguish latency from time it takes to tune. Latency happens if you want the device to tune as soon as possible, and will be mainly dominated by the latency of your general purpose OS running on your general

[Discuss-gnuradio] USRP tuning time

2015-08-09 Thread Mat Mat
Dear all, After quite some searching, I wasn't able to find information about how long it takes to retune a USRP (say, change the centre frequency). Do you guys know anything about that? Specifically, I'm using a USRP X300 with a UBX160 daughterboard. Does anyone know how long it takes in this spe

Hi Julian, Thanks for this - after a bit of googling I managed to find that as well. Was a bit hard to get started but after fiddling with the block buffers got it running the way I need it. Also for reference - in the Osmocom sink the HackRF does not have the payload length implementation based

Hi Wolfgang, sorry for the late reply. I'm not familiar with the HackRF but something that might be useful for you as it makes burst mode transmissions in GNU Radio more generic and hardware independent is Eventstream by Tim O'Shea [1]. It should be exactly what you were looking for. It kind of i

Hi David, if you've got the GNU Radio source code [1], tags_demo.cc is in gnuradio/gr-uhd/examples/c++ Now, we'll have to make a difference between "tagged streams" and "streams with stream tags", as confusing as it is: Tagged streams are like normal streams, only that GNU Radio makes sure that a

2015-08-09 Thread David Baird
I am just starting to work with a USRP in order to create burst TX and simultaneous RX streams, so I am trying to learn about tagged streams, which I believe is the way to do this. I see references in this forum to a program called tags_demo which looks like it could be very useful. Is this availab
