This patch adds support for both receiving and transmitting using
the FreeSRP. More information on the FreeSRP can be found at:
The gr-osmosdr blocks added make use of libfreesrp, the library
required for interfacing with this device. The libfreesrp source
code is freely available at
osmocom_fft -a "freesrp"
This patch adds two gr-osmosdr blocks that can be used with the SDR transceiver
application available from the Red Pitaya application marketplace:
These new source and sink blocks are based on the file block with some pieces
borrowed from the rtl_tcp block.
More details about Red Pitaya SDR transceiver can be found at:

This is based on the original work (https://github.com/Nuand/gr-osmosdr)
done by folks at nuand LLC for the gr3.6 branch of gr-osmosdr.
The following modifications have been done in this commit:
* port to gr-osmosdr master codebase (gr3.7)
* moved shared properties to bladerf_common
* added & verified IF filter bandwidth setters
* set LMS6002D registers with values taken from FAQ 5.27
* print device information (serial/versions) on startup
* added fpga= and fw= device arguments to program MCU/FPGA
* added bladerf=# dev. arg. to select a specific bladeRF
* grc gain field controls RF path VGA for RX/TX
* grc BB gain field controls BB path VGA for RX/TX
osmocom_fft -a "bladerf,fpga=/tmp/hostedx115.rbf"
The following RX named gain stages are available:
LNA: 0 to 6 dB, in 3dB steps
VGA1: 5 to 30 dB, in 1dB steps; nonlinear mapping done inside the lib
VGA2: 0 to 60 dB, in 3dB steps; not recommended to be used above 30dB
The following TX named gain stages are available:
VGA1: -35 to -4 dB, in 1dB steps, BB side
VGA2: 0 to 25 dB, in 1dB steps, RF side
Thanks a lot to the team of nuand LLC for this major contribution.
