If the lights are on, the device is streaming, guaranteed. At this point,
make sure your frequencies, gains, and antenna selections are correct.

Sorry I mean the lights were on when I closed the program.
Thanks Sam for the suggestion I will try to take a look into it.

The lights are on because the device isn't instructed to stop streaming on
program stop, and it will continue loopback operation after the host has
closed the program. You can manually issue a stream command to stop the
stream before program stop if you want to change this behavior.
Kei, why would
Hello,
I have had this issue and may be able to help. I believe that is because the rx
packet headers need to be modified before the radio will transmit them. I would
suggest looking at the siggen block and making a new ‘relay’ noc block between
the rx and tx in the fpga that modifies headers a
Thanks. After setting spp=600 and omit the DMA FIFO, it doesn't raise the
errors anymore and I can run the flowgraph without having to power cycle. I
think that is because the flow doesn't go through the host anymore. But
it's weird that after stopping the flowgraph the RX and TX lights are still

Are you using a custom FPGA image? What happens if you just omit the DMA
FIFO?
Also, set a reasonable spp in your RX Radio block arguments -- 300 to 600
is a good start.

Thanks for the reply and sorry for not providing much information. My case
is that I want to do a relay transmission with the setup: USRP 1 transmits
--> USRP 2 receives and retransmits with a shifted fc --> USRP 3 receives.
The problem is in USRP 2, as you pointed out in your post. I'm testing on
You're going to have to ask a better question than that. Please provide the
following:
* What you are trying to accomplish
* What hardware you are using
* What UHD and Gnuradio version you are using
* The approach you followed
* The result you expected
* The result you actually got

Hello, is this problem resolved? I am facing the same issue in the last
email. Also, I tried to receive the relay signal with another usrp but it
doesn't receive anything in my transmit frequency.
