Re: osmo-mgw[master]: MGCP endpoints: parse as decimal, not hex
by Neels Hofmeyr 04 Dec '17

04 Dec '17

I'd like to re-raise this patch I merged for discussion, it's about whether or not OsmoMGW endpoint identifiers are in hex. My patch might have gone in the wrong direction after all. https://gerrit.osmocom.org/4780 ~N On Sat, Dec 02, 2017 at 06:53:39PM +0000, Neels Hofmeyr wrote: > > Patch Set 2: > > elsewhere it seems we are confirming the hex nature of endpoint IDs (or was that a connection identifier?) ...

GAPK status update
by Vadim Yanitskiy 03 Dec '17

03 Dec '17

Dear Osmocom community, I have been working on GAPK (GSM Audio Packet Knife) for some time, and now I would like to share some achievements. Previously GAPK was represented as a single binary that could be called with some command line arguments in order to perform required operations. This is only handy for humans, but not for other programs, which may also need to perform some format / codec conversations or audio capture / playback. One of such programs is the mobile from OsmocomBB project. Currently, when you're making a voice call, both audio capture and playback are only possible on the L1 side, i.e. on a Calypso based phone. Of course, the audio stream can be redirected via MNCC socket, but this is not what a regular OsmocomBB user would like to do. Moreover, there is a lack of AMR codec support. Also, there is another GNURadio based project named GR-GSM. In short, this is a set of blocks for GSM signal reception, demodulation and further processing. At the moment, one has TCH Full Rate decoding capabilities only. Audio playback is not supported yet. Having these projects in my mind, I have got an idea of creating a shared library from the GAPK source code. And, a few days ago I was managed to get the audio playback working in OsmocomBB. I hope, this library will be also usable for other projects. Brief list of changes were made: - Composed a shared library named libosmogapk - All exposed symbols have got an 'osmo_gapk' prefix - Added a pkg-config manifest and a symbol export map - Integrated the Osmocom logging framework - Benchmarking is now disabled by default - Processing queue now based on the linuxlist - Fixed program exit due to ALSA buffer underrun - Fixed ALSA audio playback from file - Old gapk application was renamed to 'osmo-gapk' and linked against the library - Adjusted verbosity level (normal / debug) - Fixed I/O combinations (ALSA, RTP, file...) check All changes could be found at the fixeria/lib branch of GAPK. I hope to see them merged, and open for discussions ;) With best regards, Vadim Yanitskiy.

Hi, > <000b> trx_if.c:409 transceiver (phy0.0) rejected TRX command > with response: 'RSP SETTSC -1' > > What is the problem and how can fix it? The OsmocomBB transceiver is a legacy transceiver, so please add the following line to your 'osmo-bts.cfg': osmotrx legacy-setbsic And please let me know about the results, I'll correct the wiki. With best regards, Vadim Yanitskiy.

Re: Build failure of network:osmocom:nightly/osmo-msc in Debian_9.0/x86_64
by Neels Hofmeyr 02 Dec '17

02 Dec '17

These osmo-msc failures are inadvertently caused by https://gerrit.osmocom.org/4701, which is a good change once https://gerrit.osmocom.org/4980 is ready. But until then, I decided to revert it in https://gerrit.osmocom.org/5126. We shall re-apply it as soon as 4980 is merged. I wasn't expecting osmo-msc to use the new client library but needing the old bts_base config -- which I probably applied myself of course, but that detail was lost to me in the meantime. ~N On Fri, Dec 01, 2017 at 08:19:16PM +0000, OBS Notification wrote: > Visit https://build.opensuse.org/package/live_build_log/network:osmocom:nightly/o… > > Package network:osmocom:nightly/osmo-msc failed to build in Debian_9.0/x86_64 > > Check out the package for editing: > osc checkout network:osmocom:nightly osmo-msc > > Last lines of build log: > [ 136s] from msc_ifaces.c:24: > [ 136s] /usr/include/osmocom/mgcp_client/mgcp_client.h:108:14: note: declared here > [ 136s] struct msgb *mgcp_msg_dlcx(struct mgcp_client *mgcp, uint16_t rtp_endpoint, > [ 136s] ^~~~~~~~~~~~~ > [ 136s] Makefile:508: recipe for target 'msc_ifaces.o' failed > [ 136s] make[4]: *** [msc_ifaces.o] Error 1 > [ 136s] make[4]: Leaving directory '/usr/src/packages/BUILD/src/libmsc' > [ 136s] Makefile:424: recipe for target 'all-recursive' failed > [ 136s] make[3]: *** [all-recursive] Error 1 > [ 136s] make[3]: Leaving directory '/usr/src/packages/BUILD/src' > [ 136s] Makefile:460: recipe for target 'all-recursive' failed > [ 136s] make[2]: *** [all-recursive] Error 1 > [ 136s] make[2]: Leaving directory '/usr/src/packages/BUILD' > [ 136s] Makefile:392: recipe for target 'all' failed > [ 136s] make[1]: *** [all] Error 2 > [ 136s] make[1]: Leaving directory '/usr/src/packages/BUILD' > [ 136s] dh_auto_build: make -j1 returned exit code 2 > [ 136s] debian/rules:45: recipe for target 'build' failed > [ 136s] make: *** [build] Error 2 > [ 136s] dpkg-buildpackage: error: debian/rules build gave error exit status 2 > [ 136s] > [ 136s] cloud120 failed "build osmo-msc_1.1.2.20171201.dsc" at Fri Dec 1 20:19:10 UTC 2017. > [ 136s] > [ 136s] ### VM INTERACTION START ### > [ 140s] [ 111.258730] reboot: Power down > [ 141s] ### VM INTERACTION END ### > [ 141s] > [ 141s] cloud120 failed "build osmo-msc_1.1.2.20171201.dsc" at Fri Dec 1 20:19:14 UTC 2017. > [ 141s] > > -- > Configure notifications at https://build.opensuse.org/user/notifications > openSUSE Build Service (https://build.opensuse.org/) -- - Neels Hofmeyr <nhofmeyr(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschäftsführer / Managing Directors: Harald Welte
