Today, a Chaosradio Express (CRE) about TETRA has been released at http://chaosradio.ccc.de/cre183.html
The 2 hours and 20 minutes long interview covers the historic evolution from analog radio, trunked radio to digital trunked radion and TETRA. It also covers users, security issues and the OsmocomTETRA project.
Please note: CRE is a German language publication.
We have recently started to analyze some old Motorola Dimetra equipment, the progress can be found at Dimetra_EBTS and the follow-up pages.
Any hints on how to configure/setup/use this hardware are appreciated, especailly regarding the Ethernet protocol between BR and TSC, as well as the E1 protocol from TSC to SwMI.
We haven't had a functioning commit log mailinglist since mid-2009, when the revision control system of openbsc was converted from svn to git.
Especially today, with the large number of separate git repositories on http://cgit.osmocom.org/, it is very easy to loose track of what other developers are doing.
The new mailing list 'osmocom-commitlog' (renamed from openbsc-commits) will receive updates from all repositories on git.osmocom.org.

We're sorry to report that there are some problems with our git repositories at the moment, resulting in 'early EOF / index-pack failed' messages when users are attempting to clone one of our repositories.
The problem has been thoroughly analyzed, but even after many hours of analysis, no solution has been found yet. Your best chance is to keep re-trying the clone, in 5-10% of the cases it will succeed.
More technical details are available at this posting to the git mailing list:
Sorry for the inconvenience.
This means you can now finally log not only to stderr of the running process, but also configure any number of log files (each with its own log categories/levels) and through syslog.
In addition, all of the settings can now be configured from the vty (and persistently in the configuration file). You can also re-configure the log levels for those files (and stderr!) at runtime.
Please see the following new commands on the vty:
log file FILENAME log syslog log stderr no log (syslog|stderr) no log file FILENAME
Within each of those log vty nodes, you can then use the familiar commands like 'logging level mm debug' or 'log filter all 1' in order to configure which subsystems should log with what level of verbosity to the given target.
The abovementioned logging support is immediately available to all Osmocom programs, including osmo-nitb, osmo-bsc, gb_proxy, osmo-sgsn, bsc_nat and many others.
Today, we publicly disclose the current development version of a TETRA (Terrestrial Trunked Radio) demodulator + PHY + MAC code.
The project home page, including links to source code and mailing list is OsmocomTETRA
Today, I have moved the remaining projects on
git://bs11-abis.gnumonks.org/) to the central
This helps us to consolidate all our git repositories on one server.
The git URL of the main OpenBSC repository has changed from
git://bs11-abis.gnumonks.org/openbsc.git (read-only) email@example.com:openbsc.git (write)
git://git.osmocom.org/openbsc.git (read-only) firstname.lastname@example.org:openbsc.git (write)
In order to update your local repository with the new URL, simply use the
git remote set-url command, like in the following examples.
for those of you with read-only access:
git remote set-url origin git://git.osmocom.org/openbsc.git
for people with write/commit access:
git remote set-url origin email@example.com:openbsc.git
The other two repositories that have changed in similar way are
Sylvain Munaut was presenting on Wideband GSM Sniffing at the 27th annual Chaos Communication Congress, where he was using a series of four phones running OsmocomBB as a GSM packet sniffer.
The slides are available from http://events.ccc.de/congress/2010/Fahrplan/events/4208.en.html.
A preliminary video recording (simple dump of the stream) can be found at from this mirror
Please note: This talk was using a lot of custom software that has not been released and is not part of OsmocomBB. For more details, read this mailing list post by Sylvain Munaut
At the 27th Chaos Communication Congress, Harald Welte and Steve Markgraf have presented on OsmocomBB.
You can find the slides linked from http://events.ccc.de/congress/2010/Fahrplan/events/3952.en.html and a preliminary video recording at this mirror
The official (cut) version of the video will be released at some later point in time.
