Re: Coding Support - osmocom-sdr

15 Aug 2019

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?

  Hi Robert,

 It sounds like you're looking for the `buf_num` argument to
 rtlsdr_read_async.  This is in rtl-sdr.h:
 https://git.osmocom.org/rtl-sdr/tree/include/rtl-sdr.h#n362 .

 I run into problems like that all the time, myself.  Due to my issues,
 I've found it hard to collaborate on this project myself.  See mailing
 list archive of contributions that were minimally addressed.  I try to
 focus around communication that's more reliable than radio now, like
 memo.cash .

 But I'm still passionate about helping rtl-sdr grow.

  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?
