Decode Alerting and Progress messages and if the in-band information flag is set start decoding the voice
2018-12-29Add TCH/H decoder block with AMR multirate supportVasil Velichkov4-0/+419
Add new TCHH channel mode Add two new optional arguments -m CHAN_MODE, --mode=CHAN_MODE Channel mode. Valid options are 'BCCH' (Non-combined C0), 'BCCH_SDCCH4'(Combined C0), 'SDCCH8' (Stand-alone control channel) 'TCHF' (Traffic Channel, Full rate), 'TCHH' (Traffic Channel, Half rate) --sub-channel=TCH_H_CHANNEL TCH/H sub-channel. [default=0] --multi-rate=MULTI_RATE The MultiRrate configuration element from the Assigment Command message. Example: 28111a40. See 3GPP TS 44.018 - 10.5.2.21aa MultiRate configuration Example: grgsm_decode -m TCHH --sub-channel 0 --multi-rate 2811 -o voice.amr ...

2018-09-13burst_file_source: Fix reading longer burstsVasil Velichkov2-13/+4
- 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

2018-08-10gsm_trx_burst_if: allow to customize the bind addressVadim Yanitskiy3-6/+11
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

2017-11-29txtime_setter: clean up and simplify source codeVadim Yanitskiy2-72/+118
This change formats the block implementation source code according to a mix of GNURadio and the Kernel coding styles. The main changes are: - Limit line length to 80 columns - Preffer the opposite conditions - Do not use curly braces for single line loops / conditions For more details, see: https://wiki.gnuradio.org/index.php/Coding_guide_impl https://www.kernel.org/doc/html/v4.10/process/coding-style.html

distant future. Fixing bursts in too distant future is a bit problematic and better way than just looking at tx_time difference from current time would be desirable. This way of fixing that issue can still cause that tx part will do nothing for about 10 seconds (after switching frequency from a BTS1 (with fn1) to BTS2 (with fn2) when fn1>fn2).
