Re: [Discuss-gnuradio] UDP Sink sending bursty packets

The data rate I'm dealing with is ~30 Mbytes/s. Receiver should be able to keep up with the required data rates (but barely), but it wasn't designed to work with Ethernet packets, so it's having a hard time due to the bursty nature of the incoming UDP packets. On top of that, it's got limited rx bu

Re: [Discuss-gnuradio] UDP Sink sending bursty packets

I think if you want to smooth it out, you'll need to add the packets to a custom queue and use your own transmit thread rather than trying to do it all in the work function. That way you can send consistent-sized packets and adjust the per-packet timing if you need to. On Sun, Mar 4, 2018 at 7:

Re: [Discuss-gnuradio] UDP Sink sending bursty packets

I can't think of anything else within the GR core. The scheduler tries to maximize sample throughput, but doesn't try to do any kind of pacing. It sounds like whatever is receiving the UDP packets is operating at its limits, assuming it would work if the packets were evenly paced. Do you know

Re: [Discuss-gnuradio] UDP Sink sending bursty packets

Setting it on the UDP itself didn't change the behavior either. Do you (or anyone else) have any other ideas? Thank you Virus-free. www.avast.com

Re: [Discuss-gnuradio] UDP Sink sending bursty packets

I think you'd want to set that on the UDP sink itself. On 03/04/2018 01:30 PM, Firdavs Pulat wrote: Thanks for the suggestion, Jeff. Unfortunately, that didn't seem to help. I still see bursty packet transmission. Btw, currently I have: USRP source --> Low-Pass Filter --> ComplexToInterleaved

You are right if it were an implementation from scratch. In reality, it is just a re-implementation of your gr-ccsds fork. The real reason is that we tested your code with an USRP N310. It worked fine except some frame drops. Then we tried it with LIMESDR. The result was terrible with lots of frame

[Discuss-gnuradio] How to link OOT module in CMakeLists.txt

Now I create a OOT module named slave_demo, and I have installed it. And I can find the dynamic lib in /usr/local/lib/libgnuradio-slave-demo.so. So I link it in my CMakeLists.txt by writing like this: target_link_libraries(target ... /usr/local/lib/libgnuradio-slave-demo.so ...). I suppose th
