Hi, since I also had trouble with this issue at first, please allow me to clarify this further: GNURadio does not support looping of blocks. Inside a single block you can loop as often as you wish and that is exactly how the available PLLs in GNURadio are made. Just search the mailing list fo

Hi, it looks like the block inherits from gr_tagged_stream_block which will will call a blocks work function with the exact number of samples for one PDU with a known size in general_work and will call consume for you afterwards. http://gnuradio.org/doc/doxygen/classgr__tagged__stream__block

Hi, I would solve this with a small PHP Script on the webserver (or whatever scripting language is available on the webserver). The script can evaluate the called URL including parameters. So in the build gnuradio script you would call something like this wget http://example.com/script.php?pa

2013-05-03 Thread Martin Lülf
I had this issue once and if I remember correctly, connecting the block to the flowgraph (i.e. connect any block to your message port, even if that port will never send messages) will make your message handler react to messages from your python code. Hope this helps Martin Am 03.05.2013 19:4
