Performance issue in gnuradio version 3.10.1

2023-01-18 Thread SHAKTHIVEL S 2021 Batch,PES University
I tried running the Packet Commication example given in gnuradio documentation using gr38 embedded block. It throwed me this error "pagesize :error: no info; setting pagesize = 4096" Although this is not an error strictly it reduced the performance of the flowgraph drastically and I couldn't decode

Bit confused; you're using GNU Radio 3.10, but you specifically read a version of the tutorial that is marked as *not* applying to 3.10? On 18.01.23 17:13, SHAKTHIVEL S 2021 Batch,PES University wrote: I tried running the Packet Commication example given in gnuradio documentation using gr38 emb

It is an adaptive site I changed the blocks accordingly to 3.10 . I am simulating this on my PC. It is lagging like a hell. Can anyone give some tips to increase speed? Or I have to bear with this? The symbols are not getting decided other side due to this On Thu, Jan 19, 2023, 00:44 Aditya Arun K

The pkt_xmt/pkt_rcv example on that page works for me, with very low CPU utilization. I did have to delete and re-add the PDU/Tagged Stream blocks that have moved, but I'm sure you've already figured that one out. Could you explain the performance and lagging issue you are talking about (and in les

Yes it works for me too. But the symbols are not getting decoded on the receiver side. Just try disabling all debug and sinks on transmitter side and enable message debug and put constellation sink on receiver side alone. The BEST symbols are overlapping on one another on receiver side and not gett

The only thing I can think of is that the 48k sample rate makes some of the displays refresh at a low rate because they work on large chunks of data. Messages are getting decoded on the rx side and the displays look right. Good luck on your project! On Wed, Jan 18, 2023 at 8:45 PM SHAKTHIVEL S 20

Also it feels like the fg is for 3.8 maybe remove the blocks and try re adding them? On Thu, 19 Jan 2023 at 08:16, Aditya Arun Kumar < adityaarunkumar...@gmail.com> wrote: > > > On Thu, 19 Jan 2023 at 07:15, SHAKTHIVEL S 2021 Batch,PES University < > pes1ug20ec...@pesu.pes.edu> wrote: > >> Yes it

Hi - are you running running under Windows or Linux on the PC. And are you running a virtual machine? Check memory usage. It's possible your using  swap as memory-and are constantly swapping the memory to disk - which will slow you to crawl. -- Cinaed On 1/18/23 15:52, SHAKTHIVEL S 2021 Ba
