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.

moving away from Boost, it probably makes sense to do so in gr-osmosdr as well.
This change removes all usage of boost::mutex,
boost::mutex::scoped_lock, boost::unique_lock, and
boost::condition_variable. It also removes usage of boost::shared_ptr
and boost::weak_ptr outside of block definitions (which must continue to
use Boost until GNU Radio 3.9).

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"
|
|
Was missing from the implementation.
Now devices with a label show up nicely in GQRX

Initial build for SDRplay RSP support. Basic functionality, AGC etc. to
be added
|
|
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.

usage example:
osmosdr::device_t hint( "nofake" );
osmosdr::devices_t devs = osmosdr::device::find( hint );

- 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.

- the namespace conversion adopts the common gnuradio coding guidelines
- suffix removal is a preparation to support 8/16 bit complex data types
