27;t think statefulness is the issue. Maybe you just have super-full buffers or something like that. The packet detection is the most stable part -- can you see if that works? Just use the Schmidl&Cox block from the rx and see if it prints tags? M On 14.07.2015 08:26, Julius Durst wrote: Hi l

[Discuss-gnuradio] Reconnecting OFDM rx

2015-07-14 Thread Julius Durst
Hi list, I want to reconfigure an OFDM system. For this, I am so far simply trying to reconnect the tx and rx in the loopback example from the gr-digital ofdm examples. I made only very small modifications to it with two selector blocks, so now the flowgraph looks like this: http://i.imgur.co

Re: [Discuss-gnuradio] Hierarchical Block in c++ not working, linker or swig problem

2014-11-05 Thread Julius Durst
Hi, I forgot to edit the CMakeList.txt to add the GR components that I used (the line set(GR_REQUIRED_COMPONENTS... ). I still find it strange, that on one PC I got a linker error (which obviously was the Issue and led me to the solution) and the other one builds without complaint but okay.

[Discuss-gnuradio] Hierarchical Block in c++ not working, linker or swig problem

2014-10-28 Thread Julius Durst
Hi list. I am trying to write a hierarchical block in c++ in an OOT module. I create the block with the gr_modtool and try to make a very simple hier block. The only relevant changes to the template are: in the ...impl.cc: #include ... testhier::make()... unchanged ... gr::blocks::copy::sptr

Re: [Discuss-gnuradio] Other block as parameter in GRC

2014-08-19 Thread Julius Durst
Thank you very much for your effort. I will have a look into it. I came up with an other idea. I put my block and the filter-block in one hier-block (written in python, not in the GRC of course), in which I can pass the filter-block as parameter to my block, and use only that hier-block in the

Hi, how can I pass an other block from my flowgraph to a self written block in the gnuradio-companion? What I want to do is invoking a method of that passed block in my own one (or maybe there's an other way to do that?). I have tried passing the ID of the block to a parameter of type "raw",
