Fix build errors for osmo-fl2k in mingw
by Philip Heron 17 May '24

17 May '24

Hi all, I've attached a patch that fixes a build error for osmo-fl2k under mingw. It seems that __argc and __argv are #defined by mingw as function calls. The patch simply removes the underscores in the argument names. Some of the errors: osmo-fl2k/src/fl2k_fm.c: In function 'main': osmo-fl2k/src/fl2k_fm.c:455:35: error: passing argument 1 of 'getopt_long' makes pointer from integer without a cast [-Wint- conversion] 455 | opt = getopt_long(argc, argv, "d:c:f:i:s:", long_options, &option_index); | ^~~~ | | | int In file included from /usr/x86_64-w64-mingw32/sys- root/mingw/include/_mingw.h:10, from /usr/x86_64-w64-mingw32/sys- root/mingw/include/corecrt.h:10, from /usr/x86_64-w64-mingw32/sys- root/mingw/include/corecrt_stdio_config.h:10, from /usr/x86_64-w64-mingw32/sys- root/mingw/include/stdio.h:9, from osmo-fl2k/src/fl2k_fm.c:26: osmo-fl2k/src/getopt/getopt.h:151:29: note: expected 'int *' but argument is of type 'int' 151 | extern int getopt_long (int __argc, char *const *__argv, const char *__shortopts, | ^ osmo-fl2k/src/fl2k_fm.c:455:41: error: passing argument 2 of 'getopt_long' from incompatible pointer type [-Wincompatible-pointer- types] 455 | opt = getopt_long(argc, argv, "d:c:f:i:s:", long_options, &option_index); | ^~~~ | | | char ** In file included from osmo-fl2k/src/fl2k_fm.c:27: osmo-fl2k/src/getopt/getopt.h:151:50: note: expected 'char * const** (*)()' but argument is of type 'char **' 151 | extern int getopt_long (int __argc, char *const *__argv, const char *__shortopts, | ^ Thanks, -Phil

[PATCH] Getting device fd from command line with termux-usb
by rio＠r26.me 23 Apr '24

23 Apr '24

Hello, I am working on getting rtl-sdr working on Android inside a Termux environment. Termux-usb (https://wiki.termux.com/wiki/Termux-usb) negotiates with Android to get an fd, and the fd gets passed as command line argument to the program needing the USB device. This patch adds support for it. With it, I can run termux-usb -e "./rtl-sdr/build/src/rtl_fm -f 440M -M fm -N" /dev/bus/usb/001/002 | ./direwolf/build/src/direwolf -t 0 stdin in Termux, and connecto to it from APRSDroid. --- include/rtl-sdr.h | 2 ++ src/librtlsdr.c | 92 +++++++++++++++++++++++++++++++++++++++++++++-- src/rtl_adsb.c | 21 ++++++++--- src/rtl_biast.c | 19 +++++++--- src/rtl_fm.c | 19 +++++++--- src/rtl_power.c | 19 +++++++--- src/rtl_sdr.c | 17 +++++++-- src/rtl_tcp.c | 19 +++++++--- src/rtl_test.c | 19 +++++++--- 9 files changed, 196 insertions(+), 31 deletions(-) diff --git a/include/rtl-sdr.h b/include/rtl-sdr.h index d64701e..bd88f74 100644 --- a/include/rtl-sdr.h +++ b/include/rtl-sdr.h @@ -62,6 +62,8 @@ RTLSDR_API int rtlsdr_get_index_by_serial(const char *serial);

Release major version number change causing upgrade problems
by Carl Laufer 27 Mar '24

27 Mar '24

Hi, I just saw that the major version number was recently bumped on the osmocom rtl-sdr. Unfortunately this seems to be causing upgrade problems because if a user updates the drivers to the new major version number (eg to get Blog V4 support), the soname is now different, and this means that all previously installed software that uses librtlsdr will need to be recompiled from scratch, and software from the package manager will simply be broken. I'm not sure if the recent changes warrant a major version change and the problems that come with it? Regards, Carl

Does anyone from the community want the airprobe.org domain?
by Harald Welte 24 Jan '24

24 Jan '24

Hi all, I was approached by the person currently holding the [unused] airprobe.org domain name. I guess it was at some point registered and intended to be used for the project (back in the pre-osmocom days). As far as I know it was never actually used for that. So the question is now if anyone wants to get that domain transferred in order to do something useful with it, or whether the current registrant should simply let it expire?

Cheap RTL2832U / FC0012 gives "No supported tuner found", but has I2C devices
by Nick Burch 06 Dec '23

06 Dec '23

Hi All I bought a cheap DVB-T stick that was supposed to be a RTL2832U with a FC0012 tuner with RTL-SDR support. As might have been expected given the price, it doesn't work. The various rtl_ tools all report "No supported tuner found", eg rtl_eeprom gives: > Found 1 device(s): > 0: Generic RTL2832U OEM > > Using device 0: Generic RTL2832U OEM > No supported tuner found > Enabled direct sampling mode, input 1 > > Current configuration: > __________________________________________ > Vendor ID: 0x0bda > Product ID: 0x2838 > Manufacturer: Realtek > Product: RTL2838UHIDIR > Serial number: 00000001 > Serial number enabled: yes > IR endpoint enabled: yes > Remote wakeup enabled: no > __________________________________________ The vendor did give me a full refund suspiciously quickly, so clearly the lack of advertised RTL-SDR compatibility is well known to them! I then took the cover off, and it does have a chip that's labelled RTL2832U, plus another similar sized one I can't read the label of. After a bit of searching, I found this old post with a patch to list all the I2C devices: https://www.mail-archive.com/osmocom-sdr@lists.osmocom.org/msg00454.html That reports: > I2C devices found: > 20 a0 a2 So there is something working there, but I'm not sure if it's enough... Is there any hope for this stick? And if so, what would my next steps be? Thanks Nick

gr-osmosdr: Multiple Airspy devices
by AsciiWolf 03 Nov '23

03 Nov '23

Hello, Is there any chance the following patch could be reviewed and/or merged into upstream gr-osmosdr? It allow multiple Airspy devices to be used (which is sadly not possible without the patch). The patch is already used in the downstream gr-osmosdr package in Fedora for last two years and seems to work without issues. https://osmocom.org/issues/5144#note-4 Thanks! Regards, Daniel
