2019-05-03Filter out SoapyAudio devicesVasil Velichkov7-8/+89
When gr-osmosdr is compiled with SoapySDR support and SoapyAudio is installed the audio device is picked as a first choice when detecting devices but grgsm tools are not able to work with audio devices. So in such cases the user has to always specify the correct SDR device in the args parameter which is a bit inconvenient. When args is not specified call osmosdr.device_find to get all devices and filter out unspported ones like SoapyAudio devices. When args is specifed just try to create osmosdr.source with whatever value has been specified. Add -l and --list-devices command line option that prints information about all detected devices. Example commands: grgsm_capture --list-devices grgsm_capture --list-devices --args=nofake grgsm_capture --args=uhd,type=b210 -a 111 capture.cfile grgsm_livemon --args=rtl grgsm_livemon --args=uhd,type=b210 Change-Id: Ib84081041ca6c2bc18b9da0c32bac9d3ecef65ca

2019-03-01Major simplification and some argument changes in grgsm_capturePiotr Krysik1-167/+113
grmgs_capture tried to do too many things for a simple recorder. It was simplified by removing the receiver and ability to save data to bursts files. All other stuff that is not necessary for recording signal to disk was also removed: -setters/getters, -storing of parameters that never will be changed. The 'fc' parameter name was changed to 'freq' to follow GNU Radio guidelines. The 'shiftoff' parameter was removed. 'bb_gain' and 'if_gain' parameters were added. Variables specific to some of SDR's like: -gains at different stages, -bandwidth (not all devices can set it), -antennas (some devices have just one, some not), were moved to separate options group. What is left to be exposed is: -dc_offset_mode, -iq_balance_mode, -gain_mode. Change-Id: I092a43eaddb09a99c6cc05fde13f0ae94d9e0251

2018-09-13burst_file_source: Fix reading longer burstsVasil Velichkov4-13/+109
- Read bursts with pmt::deserialize directly from the std::filebuf - Remove the unused unserialized variable - Add tests Since df978693 when the rx_time tags are present in the incomming stream the gsm receiver adds fm_time to the burst's PMT and the bursts that burst file sink writes becomes longer because of the additional field. The burst file source block was expecting all burst to be 147 bytes long and reading files with longer bursts was failing with an unhandled exception. terminate called after throwing an instance of 'pmt::exception' thread[thread-per-block[5]: <block dummy_burst_filter (2)>]: pmt_cdr: wrong_type : #f what(): pmt::deserialize: malformed input stream, tag value = : 115 Change-Id: I989b0d6a6b214088b7880e5cbf7bb6725492dbfc
