Swig issue with floats versus doubles

So a few of us have spent a few hours trying to narrow this one down and it's now reproducible, but I'm afraid this may have some far-reaching ramifications. Swig-wrapped C++ functions using floats seem to have something like a power-of-2 rounding issue going on. if you define functions in

[Discuss-gnuradio] Updated QT GUI Fast Auto-Correlator Available

Hi everyone, In prep for GR 3.8 I noticed the fast auto-correlator sink in gr-baz is still in WX GUI last time I used it, so I ported it over to use QT GUI instead and added an option for current (dB) or normalized output. There's also a new fast auto-correlator block in the OOT module that

FYI if anyone else runs into the same issue. Ended up blowing out the install prefix and rebuilding GNU Radio as a fresh install. Seems to have fixed the issue. On Tue, Jul 16, 2019 at 7:26 PM Michael Piscopo wrote: > Hi folks, > > Has anyone else started getting an error like

[Discuss-gnuradio] OsmoSDR suddenly throwing List Contains Invalid Format after GR Update

Hi folks, Has anyone else started getting an error like this off of maint-3.7 with osmosdr as the source? return _runtime_swig.top_block_start_unlocked(r, max_noutput_items) RuntimeError: list contains invalid format! I narrowed it down with a basic flowgraph that's just an osmo source and a

[Discuss-gnuradio] Major Enhancements to gr-grnet UDP Blocks

Hi folks, Following on our amazing week at the ATA, I've been working on the network streaming blocks in gr-grnet. I've made several major upgrades: 1. UDP Source and Sinks now correctly support headers including sequence numbers, CHDR, and the old ATA format. 2. UDP source and sinks were

HI everyone, another new tracking module that now integrates with GNURadio I just released here: https://github.com/ghostop14/skytrack Skytrack takes signal tracking out past gpredict with earth-based satellites and allows tracking (doppler frequency shifts and azimuth and elevation) out to solar

[Discuss-gnuradio] New Blocks - Msg Generating Timer and Matching File Sink Blocks Added

Morning everyone, there was a question yesterday over on the USRP list about being able to record to 5 minutes, rest for an hour, then record again. I had a partial solution so I added a block I'd been wanting to add for some time to gr-filerepeater (pybombs or github). There's now a state timer

Re: [Discuss-gnuradio] making signal source based on a certain format

I ran into a similar issue a few years back and wrote an updated file block with some enhanced features. It's up on github here: https://github.com/ghostop14/gr-filerepeater. Not sure if it's an exact match for what you're looking to accomplish but you can specify delays between replays and tie

Re: [Discuss-gnuradio] I miss the TCP server and client blocks!

I felt the same way so I rewrote the TCP blocks in C++/boost with thread offloading a while back. The package should be in pybombs but you can get it here https://github.com/ghostop14/gr-grnet. Just basic TCP send/receive to replace the deprecated blocks. Hopefully it helps. Mike On Wed, May

Re: [Discuss-gnuradio] How do I interface my X310 with an NVIDIA K80 GPU in GNURadio

Hi LJ, Adding to John's recommendations if you have your heart set on the GPU, check out https://github.com/ghostop14/gr-clenabled. It's an OOT module focused on GPU acceleration of many of the core GNURadio blocks. But as John mentioned every memcpy to/from the GPU pays a performance hit which

Re: [Discuss-gnuradio] UDP Sink sending bursty packets

I think if you want to smooth it out, you'll need to add the packets to a custom queue and use your own transmit thread rather than trying to do it all in the work function. That way you can send consistent-sized packets and adjust the per-packet timing if you need to. On Sun, Mar 4, 2018 at

[Discuss-gnuradio] USRP B205 Reporting USB2 while connected to USB3

I have a USRP B205mini-i connected to a new Ubuntu 16.04 LTS laptop. The USB hardware is a standard Intel chipset and lsusb and lshw all show the hardware is in USB 3.0 mode. I've used external hard drives in the port before and I'm clearly getting USB3 performance. However when the USRP starts
