[Discuss-gnuradio] GRC - Always Generate Functions Probes Last?

2016-11-28 Thread John Malsbury
I often find that GRC instantiates function_probes/threads before the block/object/probe that is being called by the function probe, which causes an exception. It takes some trickery, like copying and re-pasting blocks in GRC to change the order in the generated python file. To fix this I've mod

This is possible. You'd write a custom block to do this. You could even do a simple POC with a python block, though it wouldn't be very fast for T/R functionality. On Mon, Nov 28, 2016 at 3:08 PM Bob Mattaliano wrote: > Hi, > > Pretty new to GNUradio, GRC and Linux. Does anyone have experienc

Something may have disabled gnuradio-companion in cmake. Can you run: *"cd ~/gnuradio/src/gnuradio/build; cmake .."*? Towards the end of the output you should see: -- ## -- # Gnuradio enabled components -- ##

Hi, Pretty new to GNUradio, GRC and Linux. Does anyone have experience with or know if possible to create a flow graph or block to switch a USB relay (as in the kind used for home automation)? What I am interested in is a block or flowgraph which examines output which also goes to the the

I have a fresh install of Ubuntu 14.04 on a tablet and am trying to install gnuradio via pybombs. I run "pybombs prefix init ~/gnuradio -a myprefix -R gnuradio-default" and it seems to complete successfully. But if I look into gnuradio/bin, there is no gnuradio-companion. Because of that, wh

[Discuss-gnuradio] Dynamic OFDM carrier allocation

2016-11-28 Thread adrian . perez . portero
Hello, I am currently implementing a system where a receiver monitors the channel, senses the non-allocated OFDM carriers, and transmits through the gaps. I have created a block that lets me estimate those gaps in the spectrum, but I have several doubts about how it interacts with the res
