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
