2018-09-13apps/grgsm_trx: remove unnecessary checks of freq_offsetPiotr Krysik2-15/+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 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

2018-09-05grgsm_trx: Migrated argument parsing to argparsePiotr Krysik2-311/+291
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 Yanitskiy2-2/+26
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 Yanitskiy4-15/+23
The new option (-b --bind-addr) allows one to specify the bind address for both DATA and CTRL interfaces. By default, '' 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 Yanitskiy7-11/+26
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.
