Hi Nitin, not involved in gr-ieee802-15-4, I can maybe still comment on the collision detection part: On 12.06.22 09:13, Nitin Shivaraman wrote: Since the preamble detection happens after the clock recovery mechanism, I want to know how the collision can be detected using correlation. Yep!

Problems specifying GUI Hints in hierarchical blocks

2022-06-13 Thread Ville Eerola
I'm trying to implement a multi-channel receiver with GNU Radio. Each channel has a number of tunable parameters, that I want to be available to the user to control via a GUI. I'm doing the design using the GNU Radio Companion. So far, I have been able to build a demonstration version of the r

Use /dev/swradioN (v4l2 api) as source

2022-06-13 Thread Stefan Oltmanns
Hello, is there any way to use devices exposed as /dev/swradioN by the v4l2 Linux kernel API with GNURadio directly? At the moment there are only two in-tree kernel drivers, one for the RTL2832U and the other for the Mirics MSi2500. For the RTL2832U librtlsdr seems to be the better option, as it

Stefan, instead of using the kernel API directly you may want to look into a SoapySDR source in GNU Radio, since the SoapySDR block is now a first class citizen in GNU Radio 3.9/3.10 According to this recent discussion in the SoapySDR GitHub repository (https://github.com/pothosware/SoapySDR/is

Thank you very much for that information, haven't seen that somebody continued the work on libmirisdr. I was able to get it working with an OsmoSDR Source using soapy=0,driver=soapyMiri I had to modify the SoapyMiri driver, as OsmoSDR sets the bandwidth to 3/4 of the sample rate, but there are on

Stefan, if I were you I would contact the author of that SoapyMiri driver on GitHub about your problems with it, since to me he seems interested in improving it and he probably would be able to run some tests on his setup to troubleshoot and fix those issues. As per my comment about using the k

Visual Studio Code extension for GNURadio

Hi, I want to inform you that I just published Visual Studio Code extension for Gnuradio. Since I use Gnuradio flowgraphs in my development environment I found that it would be good to have the possibility to run and compile .grc files from vscode via right-click menu ... feel free to install it a
