2019-05-03Filter out SoapyAudio devicesVasil Velichkov3-0/+66
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
2019-03-19Fix the TCH/H decoder and demapper XML definitionsVasil Velichkov1-0/+1
- The second argument of tch_h_decoder constructor is a string that accepts the value of MultiRate configuration element and not an enum like the tch_f_decoder decoder. - Make the demapper's burst sink required. - Make all parameters visible. - Rename the TCH/H Channel parameter to Sub-channel number. - Add the qa_tch_h_decoder test in the CMakeLists.txt - Fix several typos Change-Id: I92d4f49955c634df7d76f17cfb58d7106846c1bd

2019-01-16python/trx: rename 'change_sign_of_dict_elements' to 'dict_toggle_sign'Vadim Yanitskiy4-7/+7
The old name was quite long, resulting into cumbersome imports: from change_sign_of_dict_elements import change_sign_of_dict_elements let's use a shorter variant: from dict_toggle_sign import dict_toggle_sign Change-Id: Ie75e1d6e5e74c7c1cf34154633c1472e4b85dbb6

2018-09-13apps/grgsm_trx: remove redundant unit from freq_offset variable namePiotr Krysik1-6/+6
Frequency is always in Hz so there is no need to add that information in the variable name. Change-Id: I509771c3fe072069a680f66b0763ae6825f6d529
2018-09-13apps/grgsm_trx: remove unnecessary checks of freq_offsetPiotr Krysik1-11/+8
Checking if freq_offset is None doesn't make sense currently as it's always set to a float value by argparse (to 0 by default). Change-Id: Ie8bae1ccde60d07fc25e0b874afa5aaaac04d8a7

2018-09-13burst_file_source: Fix reading longer burstsVasil Velichkov2-0/+105
- 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

2018-09-05grgsm_trx: Migrated argument parsing to argparsePiotr Krysik1-199/+200
Argparse makes adding new parameters easier and adds consistent way of handling default values of parameters and printing of their help info. Change-Id: Idf99fd7a581464aa2f77fe01e721dbd162686811
2018-09-05apps/grgsm_trx: add baseband frequency shift featureVadim Yanitskiy1-1/+13
An ability to shift the baseband frequency would allow one to run both base stations and (OsmocomBB-based) mobile stations on any frequency (e.g. in 2.4 GHz WiFi band)! This is achieved by adding a given frequency offset to the result of "ARFCN -> RX/TX frequency" calculation. Usage example: grgsm_trx --freq-offset -500M Both RX (Downlink) and TX (Uplink) frequencies will be shifted by 500 MHz back, e.g. tuning request to ARFCN 105 would result in tuning the radio to 456.0 MHz (instead of 956.0 MHz).

2018-08-10apps/grgsm_trx: introduce bind address optionVadim Yanitskiy3-6/+7
The new option (-b --bind-addr) allows one to specify the bind address for both DATA and CTRL interfaces. By default, '0.0.0.0' is used, so there are no restrictions for the L1 source address. Change-Id: I3339f686b53db07cfd1bff9a516f4bdc28058cd9
2018-08-10gsm_trx_burst_if: allow to customize the bind addressVadim Yanitskiy1-3/+4
Pleviously remote address for DATA interface was also used as the bind address, what is definitely wrong. Let's change the API a bit in order to allow one to specify a custom bind address. Change-Id: I6e5f7b7119ac454217b8dd04f9ee0dd3b23972b6
2018-08-10trx/ctrl_if.py: send control responses to where commands are fromVadim Yanitskiy2-9/+12
When we receive a control command, we should not simply send the response to the default destination, but send it back to the exact IP/prt from which the command originated. This ensures correct routing of responses even in case multiple programs are interfacing concurrently with a control socket.

2018-08-10trx/udp_link.py: set SO_REUSEADDR socket optionVadim Yanitskiy1-0/+1
Setting this option allows one to reuse existing connections, for example, by injecting CTRL commands or DATA bursts into existing connections. Cherry-picked from: I0882c76affa9a668a12d10967081054d2b666ed1 Change-Id: I6d256683a7aa0419cd5bd0a3eaa97aefdf3254f9
2018-08-10trx/udp_link.py: close socket in destructorVadim Yanitskiy2-7/+3
Previously it was required to call the UDPLink.shutdown() method manually in order to close a socket. Let's do it automatically using the destructor of UDPLink. Cherry-picked from: I59c3dc61ec58cd9effeb789947d28fd602ca91f4 Change-Id: Ief7aa21d1e50682a90616833b679741957193aae

Some UHD devices, such as UmTRX, require one to manually reset the hardware clock, otherwise the burst transmission doesn't work. Change-Id: Idddc1387199bd22342ec5af25c8635e73352e315
