2021-01-17lib/xtrx: add missing librariesgr3.8Gwenhael Goavec-Merou1-0/+4
Linking to the libxtrx libs got lost while merging the xtrx support, which led to runtime issues when trying to use it. Signed-off-by: Gwenhael Goavec-Merou <gwenhael.goavec-merou@trabucayre.com> Signed-off-by: Eric Wild <ewild@sysmocom.de>
2021-01-10xtrx: remove BOOST_FOREACH and obsolete API callClayton Smith4-5/+6
All instances of BOOST_FOREACH were removed in an earlier commit, but it was reintroduced when xtrx support was merged. I removed BOOST_FOREACH again here. Also, xtrx support fails to build because it relies on the xtrx_open_list function, which was removed from the xtrx API in 2019. It was replaced with xtrx_open_string. I don't have xtrx hardware, so I've only tested that gr-osmosdr compiles with these changes. Signed-off-by: Eric Wild <ewild@sysmocom.de>
2021-01-04hackrf: fix bandwidth settingClayton Smith2-1/+5
The T/R switching code added in ae2253c516bfdc9ae4575ecd61fe0e6cd8608a0d fails to set custom filter bandwidths because it sets bandwidth and sample rate in the wrong order. As noted in the documentation for hackrf_set_sample_rate: "If you want to override the baseband filter selection, you must do so after setting the sample rate." To solve this problem I moved the set_bandwidth call after set_sample_rate. It was also necessary to skip the call if a custom bandwidth was not requested.

2020-12-18Fix hackrf receive hangs by checking before each lock waitv0.2.3Adrian Chadd1-2/+10
Fix receive path hangs if another thread closes down the hackrf receive whilst this buffer receive function is waiting to be woken up. Now: * Sleep for up to 100ms each time waiting for the cond to be kicked; * Check whether streaming is still enabled each time rather than only when the function is entered. This fixes hangs where consumers like gqrx via gnuradio will do a stop_rx/start_rx very quickly to change something, and the buffer receive path is waiting for a buffer.

2020-11-01Remove disabled OsmoSDR and MiriSDR codeClayton Smith10-1401/+0
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. Signed-off-by: Eric Wild <ewild@sysmocom.de>
2020-11-01rfspace: Remove broken asio codeClayton Smith2-162/+0
Asio sockets were replaced with native BSD sockets in e1b699fda04b114c8973e4cbef929781d2312ba5, and the old code was placed behind #ifdef USE_ASIO. Subsequent commits soon broke the asio code. Since it's been broken for a long time, I doubt anyone is using it, so it makes sense to remove it. Signed-off-by: Eric Wild <ewild@sysmocom.de>
2020-11-01Replace BOOST_FOREACH with range-based for loopsClayton Smith14-170/+163
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. Signed-off-by: Eric Wild <ewild@sysmocom.de>
2020-08-09HackRF: fix hackrf_source signednessv0.2.2Mike Walters2-2/+2
The LUT changes in 2e7d343fed inadvertently started interpreting samples as unsigned. This change puts it back to signed (and fixes an outdated comment). Signed-off-by: Eric Wild <ewild@sysmocom.de>
2020-08-03disable OsmoSDR as well as MiriSDR device supportv0.2.1Eric Wild1-8/+8
The actual osmosdr had only a very limited production run many years ago and is therefore of little interest to most gr-osmosdr users. Mirisdr was experimental at best, because the dongles were never widely avaialble outside of Japan and had multiple unconnected antenna ports.

Appending to lists from subdirs does not work as expected, so work around that to allow collecting the necessary libs.

2020-08-03HackRF: convert _lut to float[] to reduce size by a factor of 256Wim Lewis2-18/+11
Similar to commit 33a8d1c for RTL-SDR, this uses two lookups in a 256-element LUT instead of one lookup in a 65536-element LUT, which saves a bit of CPU cache. It also eliminates a dependency on the host's byte ordering. Signed-off-by: Eric Wild <ewild@sysmocom.de>
2020-08-03fcd: restore support for FUNcube Dongle and Pro+Clayton Smith4-46/+15
Support for the original FUNcube Dongle used to live in GNU Radio's gr-fcd module, which was removed in version 3.8. As a result, gr-osmosdr lost support for both FUNcube Dongle and FUNcube Dongle Pro+. The gr-fcdproplus out-of-tree module subsequently added support for the original FUNcube Dongle, meaning that it now supports both types. As a result, FUNcube support can easily be restored in gr-osmosdr. The now. Signed-off-by: Eric Wild <ewild@sysmocom.de> XXX
2020-08-02A lot of Boost functionality is available in C++11. Since GNU Radio is ↵Clayton Smith24-76/+82
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). Signed-off-by: Eric Wild <ewild@sysmocom.de>
2020-08-02I'm using an Airspy HF+ Discovery with the Soapy driver. Whenever I turn AGC ↵Anton Blanchard1-3/+8
off it stops receiving samples. On closer inspection, switching AGC off results in samples stalling for an extended period (hundreds of milliseconds). As such, we hit the timeout in SoapyAirspyHF::readStream() and return SOAPY_SDR_TIMEOUT (-1). Things go wrong at this point. It takes a long time before readStream() is called again, presumably because we returned 0 from work(). By this time our buffers have overflown, readStream() returns SOAPY_SDR_OVERFLOW (-2) and work() returns 0. We loop forever, continually overflowing buffers. Fix this by looping in soapy_source_c::work() when ->readStream returns SOAPY_SDR_OVERFLOW so that we consume the buffers straight away.

2020-08-02rtl_tcp: Throw an exception if TCP connection failsClayton Smith1-5/+5
Currently, rtl_tcp_source_c repeatedly calls ::connect until it succeeds. This can result in 100% CPU utilization and/or a lot of network traffic. In addition, GUI applications like Gqrx freeze up. To solve these problems, I've changed the code to report an error if ::connect fails. Signed-off-by: Eric Wild <ewild@sysmocom.de>
2020-08-02cmake: Go back CMake min ver. 3.8 by removing need for CMP0079Piotr Krysik16-19/+21
CMake 3.13 is not present in older (~2 years old) Linux distributions and GNU Radio requires min CMake version 3.8. All that is needed in order to avoid bumping CMake version is to not use 'target_link_libraries' in subdirectories. Here this is done by creating a list of needed libraries and adding them for linking at the end (like it was done in gr-osmosdr before porting to GNU Radio 3.8). One thing that is lost here is 'PRIVATE' statement in case of FCD libraries linking. Signed-off-by: Eric Wild <ewild@sysmocom.de>

2020-02-16hackrf: replace boost::assign with C++11Clayton Smith4-51/+26
Since GNU Radio is gradually replacing Boost with C++11, it seemed worth doing that for the HackRF blocks I was working on. This change removes all usage of boost::assign. From: Clayton Smith <argilo@gmail.com> Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
2020-02-16hackrf: allow transmit/receive switchingClayton Smith7-752/+693
To allow switching between transmit and receive mode within a single flow graph, I've followed the model used by the BladeRF: I factored common code into hackrf_common.cc and hackrf_common.h, and created a "_devs" map there to keep track of which devices have been previously opened. Shared pointers are used to track how many source & sink blocks are using a particular device. Because some properties (center frequency, sample rate, bandwidth, RF amplifier state, bias tee) are shared between receive and transmit, the blocks defer setting these until receiving or transmitting is started. That way a source and sink can safely use different values for these properties, and the correct values are set during T/R switching. Because the HackRF driver and/or hardware does not seem to fully transmit all samples sent to it, the code adds some silence to the end of transmissions to ensure all samples are transmitted. I've also replaced boost with C++11 code where possible. From: Clayton Smith <argilo@gmail.com> Signed-off-by: Sylvain Munaut <tnt@246tNt.com>

2018-08-15bladerf: use nchan option to enable multi-channelsRyan Tucker4-52/+52
By default, the bladeRF source and sink will expose 1 channel, unless nchan is set, in which case it will expose either that number of channels, or the number of channels supported by the device if lesser. If nchan > 1 (after validation), MIMO mode is enabled.
