OsmoSDR and MiriSDR support was disabled in v0.2.1 because the hardware
is rare and obsolete. I think it would be useful to completely remove
the associated code, since this will reduce the future maintenance
burden for gr-osmosdr.

Range-based for loops are available since C++11. Using them reduces
gr-osmosdr's dependence on Boost. Here I've done the replacement using a
global search-and-replace.

This patch adds support for both receiving and transmitting using
the FreeSRP. More information on the FreeSRP can be found at:
http://freesrp.org
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
https://github.com/freesrp/libfreesrp
Usage example:
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:
http://bazaar.redpitaya.com
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:
http://pavel-demin.github.io/red-pitaya-notes/sdr-transceiver
Usage example:
osmocom_fft -a "redpitaya=192.168.1.100:1001"

Requires https://github.com/airspy/host
Usage example:
osmocom_fft -a airspy
The following named gain stages are available:
LNA: 0 to 15, step 1
MIX: 0 to 15, step 1
IF: 0 to 15, step 1
At the moment the gains are not in dB but gain indices internal to R820t
tuner.
Usage example:
osmocom_fft -a sdr-iq=/dev/ttyUSB0
osmocom_fft -a sdr-ip=host[:port]
osmocom_fft -a netsdr=host[:port][,nchan=2]
The following named gain stages are available:
SDR-IQ: ATT: -20 to +10 dB, in 10dB steps
SDR-IP: ATT: -30 to 0 dB, in 10dB steps
The ftdi_sio driver is being used for SDR-IQ. It creates a character
device of the form:
crw-rw---- 1 root dialout 188, 0 Dec 19 22:14 /dev/ttyUSB0
To be able to open the device without root permissions add yourself to
the "dialout" group or do a "chmod 666 /dev/ttyUSB0" after pluggin in.
- implements broadcast UDP based device discovery
- prints device information (serial/versions) on startup
- reads available frequency range(s) from the device
- integrity checks of IQ stream using sequence numbers
- automatic bandpass or a wideband lowpass selectable
The following named gain stages are available:
ATT: -30 to 0 dB, in 10dB steps
Known limitations:
- setting the sample rate is possible only before the
flowgraph has been started
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
Usage example:
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.
