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 frequency or time.
There a link on their web page with details.

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 I'm
implementing.
Hi Vamshi,
First, what do you mean by turning off/on the
transmitter?

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 can
turn off/on tx between the frames?
def
main(top_block_cls=lora_TX, options=None):
tb = top_block_cls()
def sig_handler(sig=None, frame=None):
tb.stop()
tb.wait()
sys.exit(0)
signal.signal(signal.SIGINT, sig_handler)
signal.signal(signal.SIGTERM, sig_handler)
tb.start()
try:
input('Press Enter to quit: ')
except EOFError:
pass
tb.stop()
tb.wait()
if __name__ == '__main__':
main()
Thanks and Regards,
Sainath Vamshi
