[[PageOutline]] = OsmoSDR Gnuradio Source = Primarily gr-osmosdr supports the OsmoSDR hardware, but it also offers a wrapper functionality for [http://tetra.osmocom.org/trac/wiki/Funcube_Dongle FunCube Dongle], [http://files.ettus.com/uhd_docs/manual/html/build.html Ettus UHD] and [http://sdr.osmocom.org/trac/wiki/rtl-sdr rtl-sdr] radios. By using gr-osmosdr source you can take advantage of a common software api in your application(s) independent of the underlying radio hardware. == Build process == '''The gnuradio source requires a recent gnuradio (>= v3.5.3) to be installed.''' Please note: prior pulling a new version from git and compiling it, please do a "make uninstall" first to properly remove the previous version. Building with cmake: {{{ git clone git://git.osmocom.org/gr-osmosdr cd gr-osmosdr/ mkdir build cd build/ cmake ../ -Wno-dev make sudo make install sudo ldconfig }}} NOTE: The source block will appear under 'OsmoSDR' category in GRC menu. To build the API documentation: {{{ cd build/ cmake ../ -Wno-dev -DENABLE_DOXYGEN=1 make -C docs }}} == Automated installation == Marcus D. Leech has kindly integrated the forementioned build steps into his gnuradio installation script at [http://www.sbrac.org/files/build-gnuradio]. This is the most user-friendly option so far. == Device specification == You can specify the source or sink device using a comma separated string of argument=value pairs. === Local file === ||file=<path-to-file-name>|||| ||freq=<frequency>|| in Hz|| ||rate=<sampling-rate>|| in samples/s|| ||repeat=true|false|| Default is false|| ||throttle=true|false||Throttle flow of samples, default is false|| === OsmoSDR (source) === ||osmosdr=<device-index>|| || ||mcr=<rate>||Master clock rate. FIXME: Setting the MCR is not supported|| ||nchan=<channel-number>||FIXME: Values of nchan != 1 are not supported|| ||buffers=<number-of-buffers>|| Default is 32|| === OsmoSDR (sink) === FIXME: OsmoSDR sink is not yet implemented. === rtl-sdr === ||rtl=<device-index>|| || ||rtl_xtal=<frequency>|| Frequency in Hz of the crystal oscillator used for the RTL chip|| ||tuner_xtal=<frequency>|| Frequency in Hz of the crystal oscillator used for the tuner chip|| ||buffers=<number-of-buffers>|| Default is 32|| NOTE: if you don't specify rtl_xtal/tuner_xtal, the underlying driver will use 28.0MHz === rtl-sdr TCP server === ||rtl_tcp=<hostname>:<port>|| hostname defaults to "localhost", port to "1234"|| ||psize=<payload-size>|| Default is 16384 bytes|| === UHD === ||uhd|| Use this argument without value || ||nchan=<channel-index>|| || ||subdev=<subdev-spec>|| See below|| Additional argument/value pairs will be passed to the underlying driver, for more information see http://files.ettus.com/uhd_docs/manual/html/general.html#specifying-the-subdevice-to-use and http://files.ettus.com/uhd_docs/manual/html/identification.html#common-device-identifiers === FCD === ||Argument||Notes|| ||fcd=<device-index>|| || == Known Apps == The following 3rd party applications are successfully using gr-osmosdr: ||'''Name'''||'''Type'''||'''Author'''||'''URL'''|| ||gr-pocsag||GRC Flowgraph||Marcus Leech||[https://www.cgran.org/browser/projects/gr-pocsag/trunk]|| ||multimode RX||GRC Flowgraph||Marcus Leech||[https://www.cgran.org/browser/projects/multimode/trunk]|| ||simple_fm_rvc||GRC Flowgraph||Marcus Leech||[https://www.cgran.org/browser/projects/simple_fm_rcv/trunk]|| ||Wireless Temp.
