Re: [Discuss-gnuradio] GRC 3.7.11 on Windows crashes python.exe

You should post this on https://pairlist9.pair.net/mailman/listinfo/hackrf-dev mailing list. Indicate the color of the LED and it's position relative to the antenna, post the output of hackrf_info and a copy of your flowchart - the XML file with the .GRC extension. I know next to

Re: [Discuss-gnuradio] GRC 3.7.11 on Windows crashes python.exe

Martjin, On the windows build, most likely the problem is in the build scripts... we build two versions, one with maximum optimizations for AVX2 capable CPUs, and a generic one. Sometimes, however, AVX2 instructions get into the regular build for a number of reasons (qwt in particular has been

Re: [Discuss-gnuradio] Is 100 Mbps PSK demodulation in GNU RADIO possible? (x310 HW)

Dear Mehmeto, need to stress one thing, here: Your "assuming that the HW support such a speed" is kind of doing the wrong thing – you need to make your software run fast enough on your hardware, which very, very likely is too slow, and as far as I can tell, that's a real challenge at these

Re: [Discuss-gnuradio] Is 100 Mbps PSK demodulation in GNU RADIO possible? (x310 HW)

I am working on a similar system. In short, the answer is no, your i7 won't keep up that fast. But you could if you push some processing down into the FPGA. For example, my non optimized QPSK modem with 1/2 rate convolutional coding + RS coding only works up to about 1 Mbps without over/under

Re: [Discuss-gnuradio] Embedded GR-IEEE802-11

Hi Tom, define "embedded". If you use an x86 or powerful multi-core ARM Single-Board-Computer, which I'd argue can be an embedded device, then sure, I don't see any limitations with that compared to what you can do on a PC. Of course, dealing with 20 MHz channels on a poor ARM processor is very

Re: [Discuss-gnuradio] Embedded GR-IEEE802-11

Just wanted to push this inquiry back to the surface: Is anyone aware of GR-IEEE802-11 having been implemented with an embedded system? If so, what is the maximum data rate achieved? Thanks, Tom On Wed, Apr 12, 2017 at 3:22 PM, Thomas Wilkinson wrote: > Is anyone aware of

Re: [Discuss-gnuradio] GRC 3.7.11 on Windows crashes python.exe

Hi Martijn, "Illegal Instruction" is actually a proper processor fault (ie. your processor noticed a problem, and jumped to an interrupt routine telling your OS that hey, things need to be handled) that happens when one tries to execute code that isn't actually code or uses an instruction that

[Discuss-gnuradio] GRC 3.7.11 on Windows crashes python.exe

Trying to use a HackRF One with GNU Radio on Windows 10 (64-bits), installed from gnuradio_3.7.11_win64.msi. When using osmocom Source and executing the flow graph, execution halts with message: python.exe has stopped working. GRC remains alive. Crashes happen both with WX and QT. The HackRF One

[Discuss-gnuradio] Is 100 Mbps PSK demodulation in GNU RADIO possible? (x310 HW)

Dear All, We just bought an Ettus X310 with PCIe interface. We will try to transmit a 100 Mbps OQPSK signal and receive it back using the PSK demodulator blocks. In your opinion is this possible. Assuming that the HW support such a speed, will the speed of the GNU Radio Blocks be sufficient? (We
