Hi Vamshi - I vaguely remember the gr-osmosdr being optimized for
transmission - the sinks and sources have different lifetimes.
For the price of a second hackrf, you can buy the hackrf add on known as
the "operacake" which supports multiple antenna configurations - which
can configured for f

I just gave you an example in the last message. To get more information
about the stream tags, please check out the GNU Radio wiki website

Vamshi,
I don't think that HackRF One supports bursty transmission (like USRP UHD
does). If you want to achieve a 3 seconds period bursty Tx you have to
provide an adequate amount of 'null' samples between the transmission
bursts to drive DAC. To verify that information I think you can ask on
HackR
This link contains the relevant information to the structure of a flowgraph’s
top block function, which is what you pasted below.

You may find some help regarding handling burst tags in the documentation for
these blocks.

Hi Vamshi,
First, what do you mean by turning off/on the transmitter?

So what I'm doing is transmitting with a HackRF One and when I run the
flowgraph the transmission starts and frames are sent as bursts and
between the bursts, the transmitter stays on and I would like to turn it
off at tx_eob and turn on tx at tx_sob
Below is the screenshot of the current flowgraph
Hello Folks,
Here I'm implementing the transmission of LoRa Frames and I want to be able
to stop the flowgraph(Stop Transmitting) between frames say the packet is
set to transmit every 3s so at tx_eob turn off tx and tx_sob start tx.
Below is my Flow graph code snippet can you let me know how I ca

GNU Radio blocks are suitable for this job?
ZeroMq, XmlRPC, Control port ?
I have checked out ShinySDR but i uses GNU Radio simulated blocks as
plugins. (Not directly Flowgraphs)
Thank you in advance.

Ok, I have found button :), but the problem is now following. Part of my
script looks like this:
def aaa(a):
global state
state = 1
state = 1
data = [0]
if __name__ == '__main__':
parser = OptionParser(option_class=eng_option, usage="%prog: [options]")
(options, args) = parser.par
Hi all guys,
I wanted to implement a ask transmitter and a button for triggering
transmition of a single frame of data. My idea was to do that with a sort
of state machine and a button, but as far as i can see there is no button
in wx gui blocks. How do uo usually do this?
Many thanks,
