gr-soapy mishandles hackrf on flowgraph exit

I had previously thought that there was an issue with the save/restore of the geometry of the QT window, but I determined that it was a problem when using the gr-soapy block with a hackrf, so I have started a new thread. If I make a flowgraph using the "Soapy hackrf source" (i.e. gr-soapy block

Re: Options - QT GUI window size and placement

not a functionality of GNU Radio itself (at least we don't have any calls to the Qt-typical "saveGeometry"/"restoreGeometry" in our source code); it must be your window manager? So, I sadly can't advise on how to achieve that, sorry. Best, Marcus On 13.04.22 18:50, Gavin Jacob

Options - QT GUI window size and placement

I recently built a laptop with Ubuntu 20.04 and then built gnuradio 3.10.2 from source. I noticed that the Hackrf is now supported through the SoapySDR source/sink blocks (rather than the Osmocom blocks), so I made some examples & tests of hackrf rx and tx. Works fine, but I have a question.

Re: 3.9 Setup for OOT development

As promised, here is a link to the source for a simple OOT module/block that works on GNU Radio 3.9. The code shows how to handle variable # of inputs, and how to setup a callback when a parameter changes during runtime. You can find the block at: https://github.com/eejake52/gr-stream There is

I made some progress on this and now I have my OOT module/block working on Ubuntu 20.4, GNU Radio 3.9, written in C++, with callbacks and variable # of inputs. There are two key things to report. First is the workflow. None of the tutorials on the wiki (that I found) were complete, but

Re: New Raspberry PI Complete OS release

Glen, I'm going through a pain similar to yours. For working examples, you can look at the source for the blocks that are part of GNU Radio. For example, the Multiply Constant block shows how to do a callback, and the Add block shows how to do variable number of inputs. Unfortunately, these

Re: How to set variable number of inputs/outputs in Python OOT modules

In 3.7, you would use the tag, but in 3.8 the trick to setting multiple ins/outs in the YML file, is the keyword "multiplicity". You can see the details of how to configure here: https://wiki.gnuradio.org/index.php/YAML_GRC YAML GRC - GNU Radio

Re: 3.9 Setup for OOT development

@Criss Swaim - you were partly right. The problem was in the yml file, but not because I skipped that makeyaml step. The 'gr_modtool add' step provides a template yml file, which is a better starting point than the output of 'gr_modtool makeyaml'. The output of the

3.9 Setup for OOT development

I am planning to update an OOT module I wrote 4 years ago. I setup a laptop with a fresh install of Ubuntu 20.04 to use for development. I installed GNU Radio 3.8, but then I decided to go with 3.9, so I removed 3.8, and installed 3.9 from the PPA. Then I ran modtool newmod streamx ... cd
