TETRA SNDCP to a local tun/tap device
by Mccauley 24 Jul '13

24 Jul '13

Hi, According to the information in the wiki currently osmo-tetra can forward IP packets contained in TETRA SNDCP to a local tun/tap device have not seen any details of how to do this anywhere in code or wiki.... So I ask, it falls within a these features left unfinished? or is possible with the current code base? If so can anyone provide some example of how to do it. Best regards, -- <>

You can try this hack I'm using to filter out encrypted traffic and for SSI logging of traffic. There are also a couple of lines I've commented out to write traffic to a pipe for realtime speech decoding. It's a patch against the current master branch, it already includes Sylvains TCH code.

Timeslot assignment in group calls
by Mike Puchol 19 May '13

19 May '13

Hi all, I'm modifying the code to provide more information on group calls, and a more "friendly" display of a call from setup to completion. One doubt I have and can't seem to find in the Air Interface specs is how/where a particular timeslot is assigned to a particular call. For example, a call may be assigned a Usage Marker of 16, but so could a second all to a different group that takes place simultaneously. With which PDU is the TN assigned to a particular call? Best, Mike

[ANNOUNCE] OsmoDevCon 2013-04-04 till 2013-04-07, Berlin
by Harald Welte 27 Feb '13

27 Feb '13

Dear fellow Osmcoom developers, it is my pleasure to finally announce the date + venue of OsmoDevCon 2013: Date: April 04 through April 07, 2013 Place: IN-Berlin, Lehrter Str. 53, Berlin Like last year, this is an event for developers of the various Osmocom proejects. Reservation and confirmation of reservation is required. The event is free of charge. The Room is made available by IN-Berlin e.V., an Internet related non-profit organization. Lunch catering will be sponsored (so far by sysmocom GmbH, but if any other sponsors come up, we are happy to share the cost). So all you have to cover is your own travel + accomodation costs, as well as breakfast and dinner. If you are an active developer and cannot afford travel/accomodation, please let me know and I'll see if we can do something about it. If you would like to attend, please send a message to laforge(a)gnumonks.org applying for registration of the event. The registration deadline is March 5, i.e. one week from now. There is no detailed schedule of talks yet. I will start a separate discussion suggesting / collecting topics in the next couple of days. More information is (and will be made) available at http://openbsc.osmocom.org/trac/wiki/OsmoDevCon2013 Further discussion regarding the event should be directed at the osmocom-event-orga(a)lists.osmocom.org mailing list, to avoid cross-posting over the various project-specific lists.
