Hello Sorry for my poor english. Can anyone Help me with the same Problem as http://lists.osmocom.org/pipermail/baseband-devel/2011-January/000939.html I have connect the Motorola C123 with the following cable ( http://www.cellcorner.com/xshp/unlock-phone-codes/motorola-t190-t191-t193-u… ) directly to a rs232 and to a usb->rs232 adapter. Result, same Probleme than in the Post "Osmocon not loading". What do you think makes the cable or the mobile phone problems? greetings lukas

layer23 bursts - strategy for filtering IA's for tmsi based on downlink traffic only?
by MATTHEW EVANS 23 Feb '11

23 Feb '11

Hi all, I am running some tests/experiments with the burst_ind branch. I want to be able to only follow the immediate assignments for my TMSI as it is difficult to verify that the bursts are indeed my traffic. However, I suspect this is not possible using only downlink traffic as without the channel request from the MS I cannot match the resulting IA? I would need to capture uplink too? I would be grateful if someone could confirm if this is the case or if there is a way around this issue? Many thanks, Matt.

Hi guys I think that many of you know opencellid. Did you find its info precise? When querying for cells of my area, I get a positioning that is far far away from the right one. Are there other areas where their positioning is better? Dario.

Extract Kc from Phone?
by MATTHEW EVANS 22 Feb '11

22 Feb '11

Hi all, Does anyone have any suggestions with regard to models of phone in which it is easy to view the current Kc? I have a Motorola C115, Nokia 3310/6630, Android Desire, iPhone etc. I can get every everything from the in built field test modes, however I really want to get the current session key so that I can verify/analyse my captured bursts. Thanks, Matt.

Re: off-topic apologies - how to unlock sim (not phone)

Hi, the phone does not seem to be involved in this topic. It's only about the SIM. And you can't flash a sim like a baseband. That would be too easy.

AW: AW: Fwd: gpsd support
by Andreas.Eversberg 22 Feb '11

22 Feb '11

hi dario, i just tried to compile master and your patch. (heaving gpsd installed) here are some problems: CC gps.o gps.c:41: error: 'gps' redeclared as different kind of symbol /usr/include/gps.h:127: error: previous definition of 'gps' was here gps.c: In function 'osmo_gpsd_cb': gps.c:73: warning: implicit declaration of function 'gps_waiting' gps.c: In function 'osmo_gpsd_open': gps.c:123: warning: implicit declaration of function 'gps_stream' gps.c:123: error: 'WATCH_ENABLE' undeclared (first use in this function) gps.c:123: error: (Each undeclared identifier is reported only once gps.c:123: error: for each function it appears in.) 1. the symbol "gps" is used as structure instance for struct osmo_gps. it is also used in an enum declaration at /usr/include/gps.h: ... enum {gps, glonass, unknown} system; ... 2. the declarations 'gps_waiting', 'gps_stream', 'WATCH_ENABLE' are not defined at gps.h this is maybe one reason why i failed to write gpsd support. symbols in the howtos and examples were missing. here is the latest version i got from the gentoo repository: * sci-geosciences/gpsd Latest version available: 2.32 Latest version installed: 2.32 Size of files: 603 kB Homepage: http://gpsd.berlios.de/ Description: GPS daemon and library to support USB/serial GPS devices and various GPS/mapping clients. License: BSD any ideas? andreas

> Then try to find what's the minimum version (see api changes in the > gpsd history I guess) and make sure in the configure to check it. i found it at http://gpsd.berlios.de/. not both apis must be supported, at least check for version 2.90 or later, to decide to use gpsd.

off-topic apologies - how to unlock sim (not phone)
by Scott Weisman 22 Feb '11

22 Feb '11

I apologize for this in advance. I figure the collective GSM knowledge here might be able to help me. I have a SIM card that can only be used on one phone. The phone itself is unlocked. But the SIM won't work on any other phone. Does anyone know anything about this or how to unlock a SIM to work on any phone? Yes, I have tried searching, but because PHONE unlocking is such a common theme, this just passes through the cracks. Thanks, Scott
