= 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=<mcr>||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||
||tunner_xtal=<frequency>|| Frequency in Hz of the crystal oscillator used for the tunner chip||
||buffers=<number-of-buffers>|| Default is 32||
NOTE: if you don't specify rtl_xtal/tunner_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>|| ||
