2019-05-02Improve the TCH/H decoder logsVasil Velichkov1-1/+8
- Change "6,90 kbit/s" to "5.9 kbit/s" A typo reported in github ptrkrysik/gr-gsm#456 - Comment out the "Error! frame_nr:" message as it turns out to confuse users more then it actually helps debugging. - When voice-boundary detection is enabled write the name of decoded control channel messages Change-Id: I697ef944f30c4cabb62c888317dd3a7f8dcd5611

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
