rtlsdr_read_reg failed with -7
by Petter Gustad 11 Oct '13

11 Oct '13

I keep getting the message "rtlsdr_read_reg failed with -7" whenever I run any of the rtl_ commands. When I run the command after re-plugging the stick it usually works (except the lost samples): rtl_test Found 1 device(s): 0: ezcap USB 2.0 DVB-T/DAB/FM dongle Using device 0: ezcap USB 2.0 DVB-T/DAB/FM dongle Found Fitipower FC0013 tuner Supported gain values (23): -9.9 -7.3 -6.5 -6.3 -6.0 -5.8 -5.4 5.8 6.1 6.3 6.5 6.7 6.8 7.0 7.1 17.9 18.1 18.2 18.4 18.6 18.8 19.1 19.7 Info: This tool will continuously read from the device, and report if samples get lost. If you observe no further output, everything is fine. Reading samples in async mode... lost at least 84 bytes But if I run any of the rtl_ commands after breaking any previous running command I get: rtl_test Found 1 device(s): 0: ezcap USB 2.0 DVB-T/DAB/FM dongle Using device 0: ezcap USB 2.0 DVB-T/DAB/FM dongle rtlsdr_read_reg failed with -7 rtlsdr_write_reg failed with -7 rtlsdr_read_reg failed with -7 rtlsdr_write_reg failed with -7 rtlsdr_read_reg failed with -7 rtlsdr_write_reg failed with -7 Is there a way to completely reset the driver other than re-plugging it? I'm running Gentoo Linux (3.2.1 kernel) Thanks! //Petter

rtl_tcp.c:112:10: error: invalid suffix "Ui64" on integer constant

Hi All, Just been trying to compile rtl-sdr on my Windows7x64; so I have cloned the trunk repository, download mingw64, download cmake, get libusb-1.0 for windows and get pthreads-win32. After all I have configured cMake with the parameter show below: CMAKE_RC_FLAGS:STRING= CMAKE_VERBOSE_MAKEFILE:BOOL=0 CMAKE_RC_COMPILER:FILEPATH=C:/Program Files/mingw-builds/x64-4.8.1-posix-seh-rev5/mingw64/bin/windres.exe CMAKE_AR:FILEPATH=C:/Program Files/mingw-builds/x64-4.8.1-posix-seh-rev5/mingw64/bin/ar.exe CMAKE_C_FLAGS:STRING= CMAKE_C_FLAGS_DEBUG:STRING= CMAKE_EXE_LINKER_FLAGS_DEBUG:STRING= CMAKE_USE_RELATIVE_PATHS:BOOL=1 CMAKE_C_STANDARD_LIBRARIES:STRING=-lkernel32 -luser32 -lgdi32 -lwinspool -lshell32 -lole32 -loleaut32 -luuid -lcomdlg32 -ladvapi32 -lstdc++ CMAKE_C_COMPILER:FILEPATH=C:/Program Files/mingw-builds/x64-4.8.1-posix-seh-rev5/mingw64/bin/x86_64-w64-mingw32-gcc.exe CMAKE_CODEBLOCKS_EXECUTABLE:FILEPATH=C:/Program Files/mingw-builds/x64-4.8.1-posix-seh-rev5/mingw64/bin/mingw32-make.exe LIBUSB_INCLUDE_DIR:PATH=E:/Staniscia/PRIVATO/RTL_SDR/libusbx/include/libusbx-1.0 LIBUSB_LIBRARIES:FILEPATH=E:/Staniscia/PRIVATO/RTL_SDR/libusbx/MinGW64/static/libusb-1.0.a THREADS_PTHREADS_INCLUDE_DIR:PATH=E:/Staniscia/PRIVATO/RTL_SDR/pthreads-win32/Pre-built.2/include THREADS_PTHREADS_WIN32_LIBRARY:FILEPATH=E:/Staniscia/PRIVATO/RTL_SDR/pthreads-win32/Pre-built.2/lib/x64/libpthreadGC2.a and I don't have any warning from cMake but when I make the project I have this: ---------------------- E:\Staniscia\PRIVATO\RTL_SDR\repo\rtl-sdr\build>mingw32-make.exe clean E:\Staniscia\PRIVATO\RTL_SDR\repo\rtl-sdr\build>mingw32-make.exe [ 5%] Building C object src/CMakeFiles/libgetopt_static.dir/getopt/getopt.c.obj Linking C static library liblibgetopt_static.a [ 5%] Built target libgetopt_static [ 10%] Building C object src/CMakeFiles/rtlsdr_shared.dir/librtlsdr.c.obj [ 15%] Building C object src/CMakeFiles/rtlsdr_shared.dir/tuner_e4k.c.obj [ 21%] Building C object src/CMakeFiles/rtlsdr_shared.dir/tuner_fc0012.c.obj [ 26%] Building C object src/CMakeFiles/rtlsdr_shared.dir/tuner_fc0013.c.obj [ 31%] Building C object src/CMakeFiles/rtlsdr_shared.dir/tuner_fc2580.c.obj [ 36%] Building C object src/CMakeFiles/rtlsdr_shared.dir/tuner_r820t.c.obj Linking C shared library librtlsdr.dll [ 36%] Built target rtlsdr_shared [ 42%] Building C object src/CMakeFiles/rtl_adsb.dir/rtl_adsb.c.obj Linking C executable rtl_adsb.exe [ 42%] Built target rtl_adsb [ 47%] Building C object src/CMakeFiles/rtl_eeprom.dir/rtl_eeprom.c.obj Linking C executable rtl_eeprom.exe [ 47%] Built target rtl_eeprom [ 52%] Building C object src/CMakeFiles/rtl_fm.dir/rtl_fm.c.obj Linking C executable rtl_fm.exe [ 52%] Built target rtl_fm [ 57%] Building C object src/CMakeFiles/rtl_sdr.dir/rtl_sdr.c.obj Linking C executable rtl_sdr.exe [ 57%] Built target rtl_sdr [ 63%] Building C object src/CMakeFiles/rtl_tcp.dir/rtl_tcp.c.obj ..\..\src\rtl_tcp.c: In function 'gettimeofday': ..\..\src\rtl_tcp.c:112:10: error: invalid suffix "Ui64" on integer constant tmp -= 11644473600000000Ui64; ^ src\CMakeFiles\rtl_tcp.dir\build.make:57: recipe for target 'src/CMakeFiles/rtl_tcp.dir/rtl_tcp.c.obj' failed mingw32-make.exe[2]: *** [src/CMakeFiles/rtl_tcp.dir/rtl_tcp.c.obj] Error 1 CMakeFiles\Makefile2:319: recipe for target 'src/CMakeFiles/rtl_tcp.dir/all' failed mingw32-make.exe[1]: *** [src/CMakeFiles/rtl_tcp.dir/all] Error 2 Makefile:115: recipe for target 'all' failed mingw32-make.exe: *** [all] Error 2 ---------------------- Someone can help me?

Can I use rtl_sdr to evaluate my antenna?
by Alessandro Staniscia 08 Oct '13

Hi all, I have built my antenna and now I wont evaluate my work, so, in your opinions can I use the rtl_sdr software to accomplish it? Someone have a suggestion or is it impossible? Thanks

rtl_? for radio control?
by Alan Corey 27 Sep '13

27 Sep '13

OK, so you plug a $20 dongle into a Raspberry Pi, hook some stuff to the GPIO connector and with probably minor tweaks to something like RTL_FM you can use it as a radio in radio-controlled model planes, cars, boats. Add the Pi's $25 camera and you could have a radio-controlled camera, useful for sending up in a radio-controlled plane or doing wildlife photography. If you've got some analog (pulse position) channels those would be good for rudder, flaps, various camera settings. This can be done in the 27 MHz CB band or with a ham license in something like the 6 meter ham band. I had no trouble getting RTL_FM running on my Pi but it probably doesn't have enough CPU horsepower to do a lot of processing on the dongle side and on the imaging side at the same time. Anybody done this? Alan ----- Radio Astronomy - the ultimate DX

LIBUSB_ERROR_PIPE?
by Gisle Vanem 25 Sep '13

25 Sep '13

Since my last Windows Update (not sure that's the cause), I'm having a hell to regain access to my Terratec DVB-Tstick with ther Elonics E4000 tuner. I've modified librtlsrc.c to include some more traces and relinked rtl_test with it. All I'm getting is LIBUSB_ERROR_PIPE trying to read/write the I2C-bus: Osmocom-SDR\src\rtl_test.exe Found 1 device(s): 0: Terratec T Stick PLUS Using device 0: Terratec T Stick PLUS librtlsdr.c(392): I2C addr C8: got 00, rd_len: -9, wr_len: -9 librtlsdr.c(394): Read error: LIBUSB_ERROR_PIPE, Pipe error librtlsdr.c(396): Write error: LIBUSB_ERROR_PIPE, Pipe error librtlsdr.c(392): I2C addr C6: got 00, rd_len: -9, wr_len: -9 ... No supported tuner found Enabled direct sampling mode, input 1 Supported gain values (1): 0.0 ---------------- What could be the reason for this? What else should I try? --gv

LabVIEW support for rtl_tcp
by András Retzler 25 Sep '13

25 Sep '13

Hi, I've made some SubVIs for LabVIEW to support rtl_tcp. http://ha5kfu.sch.bme.hu/sites/default/files/public/sdrlab-rtl_tcp-interfac… I hope that someone will find it useful. More information and screenshot: http://ha5kfu.sch.bme.hu/sdrlab -- I'd like to say thanks for your work on the RTL-SDR project, it's something really cool :-) Regards, András Retzler HA7ILM

gr-iqbalance documentation build problem
by wk＠ire.pw.edu.pl 19 Sep '13

19 Sep '13

Hello. I have some build problem with building gr-igbalance with documentation enabled. Build fails with a message saying that shell interpreter can't execute Doxyfile. It is the same as I noticed some time ago while building gr-osmosdr (see http://lists.osmocom.org/pipermail/osmocom-sdr/2013-April/000553.html ). It was solved by the patch by Jaroslav Škarvada ( http://cgit.osmocom.org/gr-osmosdr/commit/?id=2f6592566bd60d2539f5b976dcf61… ). Similar patch, attached, help for gr-iqbalance. It moves doxygen detection test to toplevel CMakeLists.txt. Please add it to git repository. Wojciech Kazubski
