osmocom sink issue in GNU Radio 3.10.7

by edwar ewer

Dear gr-osmocom developers, I have a project that uses Jetson Xavier NX and BladeRF 2.0 to transmit and receive radar signals. I decided to use GNU Radio and gr-osmocom to do that task. Unfortunately, I encountered an error that, I think, GNU Radio failed to read all the parameters. This is the first time that I face this kind of error. I have been using GNU Radio for a while in a PC or Raspberry Pi but never see an error like this. Do you have any idea where is this error coming from and how to deal with it? Your suggestions are highly appreciated. Thank you. Best regards, Edwar [image: Screenshot from 2025-02-14 10-52-25.png] in osmocom sink and source.

[PATCH] Make osmocom_fft timezone-aware

Hi, I just stumbled across the problem that osmocom_fft's default recording filename does not contain the timezone. I think it would be a good idea to change that, and I hope you agree :) The change I propose is relatively simple: diff --git a/apps/osmocom_fft b/apps/osmocom_fft index c48ac7ee15..05a6de842c 100755 --- a/apps/osmocom_fft +++ b/apps/osmocom_fft @@ -326,7 +326,7 @@ class app_top_block(gr.top_block, Qt.QMainWindow): s = self._fre.text() s = s.replace('%S', '%e' % self.src.get_sample_rate()) s = s.replace('%F', '%e' % self.src.get_center_freq()) - s = s.replace('%T', datetime.datetime.now().strftime('%Y%m%d%H%M%S')) + s = s.replace('%T', datetime.datetime.now().astimezone().strftime('%Y%m%d%H%M%S%z')) return s def _set_status_msg(self, msg, timeout=0): CU, Sec -- "This 'telephone' has too many shortcomings to be seriously considered as a means of communication.

Fix build errors for osmo-fl2k in mingw

by Philip Heron

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

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

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

[PATCH] lib/xtrx: honouring/using the loglevel parameter

by Gwenhael Goavec-Merou

loglevel parameter is never used and let loglevel to DEBUG, with an annoying flood of message in terminal. This patch adds a call to xtrx_log_setlevel() at xtrx constructor level.

Does anyone from the community want the airprobe.org domain?

by Harald Welte

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

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
