Gwenhael Goavec-Merou a6afeaa3a1 lib/xtrx: honouring/using the loglevel parameter
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.

gr-osmosdr - generic gnuradio SDR I/O block

While originally being developed for the OsmoSDR hardware, this block has become a generic SDR I/O block for a variety of SDR hardware, including:

By using the gr-osmosdr block you can take advantage of a common software API in your application(s) independent of the underlying radio hardware.

Homepage + Documentation

For installation and usage guidelines please read the documentation available at

For the impatient :) a short excerpt:

The Gnu Radio block requires a recent gnuradio (>= v3.7) to be installed.

Before building the block 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
cd gr-osmosdr/
mkdir build
cd build/
cmake ../
sudo make install
sudo ldconfig

NOTE: The osmocom blocks will appear under Sources and Sinks categories in GRC menu.


We welcome any gr-osmosdr related discussions in the SDR section of the osmocom discourse (web based Forum).
