Coding Support
by Hudspeth, Robert Lee 16 Aug '19

16 Aug '19

Hello! I am an undergraduate student at Oregon State University working with RTL-SDR dongles for an academic project under supervision from Benjamin Brewster, and I had a dev question. I'm trying to run utilities that capture 978 <https://github.com/mutability/dump978> & 1090Mhz <https://github.com/mutability/dump1090> traffic simultaneously, but I can't seem to stop rtl_sdr from allocating too many zero-copy buffers and preventing both programs from running simultaneously (I'd like to cut down from 15). I've been through librtlsdr.c and rtl_adsb.c with the hope of manually changing some variable that will let me accomplish this to no avail. Is there some line I might have overlooked, or some additional parameter(s) I might need to enter?

Thank you for your email, and I appreciate the communication. I did have one last question: If I were to make a change to the code and need to recompile it, are the steps the same ones listed on the wiki under "building the software", or is there a different make process?

I have enabled the direct sampling option to the rtl_tcp. I would like to submit it as a PR but I need authorization. How do we get authorization? Thanks, Richard Frye

Dear Steve, Could you give a note if there is still work in progress for a linux fix? I noticed I am affected by this on 5.2, and the last message I find about this is yours on the arm-kernel list dating back to 9 Nov 2018. Thanks, Nuno
