Re: Controlling flowgraph

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

Vamshi, 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 https://wiki.gnuradio.org/index.php/Stream_Tags Marcin pon., 6 cze 2022 o 15:46 Vamshi Sainath Gavani napisał(a): > can you give me an example of

Re: Controlling flowgraph

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

Re: Controlling flowgraph

This link contains the relevant information to the structure of a flowgraph’s top block function, which is what you pasted below. https://wiki.gnuradio.org/index.php/Handling_Flowgraphs 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? Marcin pon., 6 cze 2022 o 09:14 Vamshi Sainath Gavani napisał(a): > 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

Re: Controlling flowgraph

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

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

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, --
