Re: ubuntu 16.04: nothing works!

I've been having problems with my Arch Linux system completely locking up with API 1.94 and API 1.95-1 as well. API 1.95-2 had a symbol error, so it never got to the point of testing it. I'm now using SoapySDR API Version v0.5.0-g37c7ea4b, ABI Version v0.5-2 with the API version 1.95-1. After findin...

Re: API (1.94) and EXTIO plugin (3.9) released - still locks up kernel on Ubuntu 16.04

I gave it a try, but I'm getting an error in SoapySDRUtil --probe. The same error prevents CubicSDR from loading: symbol lookup error: /usr/lib/libmirsdrapi-rsp-1.95.so: undefined symbol: libusb_init Reinstalling 1.95.1 eliminates the SoapySDRUtil --probe errors, but I haven't tested CubicSDR yet as...

Re: API (1.94) and EXTIO plugin (3.9) released - still locks up kernel on Ubuntu 16.04

It has the same problem with Arch Linux, currently on kernel 4.6.3 and systemd 230-5. I've had the lockup problem with the SoapySDR/CubicSDR combination for a several weeks now. I finally gave up trying to fix it, hoping the new API would solve the problem. After the new API came out, I removed all ...

Re: Linux

Hi Franco -- Sorry to hear about your problems with GQRX. If you compile gr-osmsosdr with my sdrplay code, it will output the buffer status when it overflows/underflows. That can be helpful in tracking down problems. A safe starting point is sample rate at 1536000 and bandwidth at 1536000. I can sen...

Re: Linux

I haven't been active here since completing the modifications to the gr-osmosdr code (see Page 4 of this forum). Using my modified sdrplay_source.c.cc code, GQRX is working okay for me. It isn't very smart with regards to the sampling rate and bandwidth but if you enter values supported by the SDRpl...

Re: SDRPlay with Ubuntu 14.04 64 bit and SDR-J - added GQRX tips

There's still some work needed on the SDRplay / GQRX interface, but if you enter these values it should work fine: Sampling rate - one of these 8000000 5000000 2500000 2048000 2000000 1536000 -- I usually use 1536000 Bandwdith: I don't recall all the wider bandwidths I've tested, but I use these the...

Re: SDRPlay with Ubuntu 14.04 64 bit and SDR-J

Here's what my working udev rule (saved as 66-mirics.rules) looks like: SUBSYSTEM=="usb",ENV{DEVTYPE}=="usb_device",ATTRS{idVendor}=="1df7",ATTRS{idProduct}=="2500",MODE:="0666" It shouldn't make any difference, but I've got SDR-J programs in a directory off of my home directory, where I've got writ...

Re: Linux (new code)

Congratulations! I think you've got it! In spite of my reservations in the previous email, the github code is working fine! I tested the github code after adding the same limited debug routine I used in my test-0919-49 version and I'm not seeing any sample errors, even during long runs. Comparisons ...

Re: Linux

I looked at the Mirics code and it's good to see they removed the last bits of debug code and streamlined it a bit. I'd expanded some of the code to make it easier for me to understand and modify during my testing. I won't have a chance to test it until after work today but I have a few concerns wit...

Re: Linux

Thanks Amish -- I don't need the I/Q output, just the console output when you run GQRX from a terminal and maybe a screen shot if you see anything odd. You should be able to cut and paste it using the code button above. The key thing I'm looking for is whether any packet handling errors (from the co...
