 = OSMOCOM Gnuradio Source = 

 While primarily being developed for the OsmoSDR hardware, this block as well supports: 

  * [ FunCube Dongle] through libgnuradio-fcd 
  * [ OSMOCOM OsmoSDR] Devices through [ libosmosdr] 
  * [ Great Scott Gadgets HackRF] through [ libhackrf] 
  * [ Ettus USRP] Devices through [ Ettus UHD library] 
  * RTL2832U based DVB-T dongles through [ librtlsdr] 
  * RTL-TCP spectrum server (see librtlsdr project) 
  * MSi2500 based DVB-T dongles through [ libmirisdr] 
  * gnuradio .cfile input through libgnuradio-core 

 By using the OsmoSDR block 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 (>= v3.6.4.1) to be installed.''' 

 Before building the source you have to make sure that all the dependencies (see list of supported devices above) you are intend to work with are properly installed. The build system of gr-osmosdr will recognize them and enable specific source/sink components thereafter. 

 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:// 
 cd gr-osmosdr/ 
 mkdir build 
 cd build/ 
 cmake ../ 
 sudo make install 
 sudo ldconfig 

 NOTE: The OSMOCOM source block will appear under 'Sources' category in GRC menu. 

 To build the API documentation: 
 cd build/ 
 cmake ../ -DENABLE_DOXYGEN=1 
 make -C docs 

 == Automated installation == 

 Marcus D. Leech has kindly integrated the forementioned build steps into his gnuradio installation script at []. 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. 

 The always-up-to-date block documentation is available [ right here]. 

 === IQ File Source === 
 ||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|| 

 === FCD Source === 
 ||fcd=<device-index>|| || 

 === 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|| 

 === RTL-SDR Source === 
 ||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 Source === 
 ||rtl_tcp=<hostname>:<port>|| hostname defaults to "localhost", port to "1234"|| 
 ||psize=<payload-size>|| Default is 16384 bytes|| 

 === UHD Source / Sink === 
 ||uhd|| Use this argument without a value || 
 ||nchan=<channel-index>|| || 
 ||subdev=<subdev-spec>|| See below|| 

 Additional argument/value pairs will be passed to the underlying driver, for more information see and 

 === HackRF Source / Sink === 
 ||hackrf|| Use this argument without a value. Only the first device found may be used ATM because of libhackrf limitation. || limitation.|| 
 ||buffers=<number-of-buffers>|| Default is 32||
