This Sunday (May 13), we're planning to do some of the pending migration of osmocom.org services from our old server to a new machine.
This will cause some downtime. Hopefully it will be minimal, but for sure there will be unexpected events that will mean some of the osmocom.org services will be unavailable at some point during Sunday :/
In terms of priorities, gerrit is high up on the list, so this is the primary focus. If that goes well, redmine is the next on the list.
In case you're interested in the gory details, #3076 is the overview ticket.
All of the video recordings made at the recent 2018 Osmocom Developer Conference (OsmoDevCon2018) have meanwhile been released.
You can find the recordings at https://media.ccc.de/b/conferences/osmocon/osmodevcon18 with a back-up at this youtube playlist
Please excuse the bad audio quality in the Welcome to OsmoDevCon 2018 talk. We didn't pay attention to the clipping and only resolved it towards the end of that talk. All other videos have proper audio quality.
The Ettus USRP1 hardware was the first SDR device that could be used to implement a GSM base station. At Osmocom we never removed the related support from OsmoTRX, but it was getting rather hard to use with USRP1 due to two reasons:
- libusrp had been removed from gnuradio after gnuradio 3.4.2 in FIXME
- OsmoTRX could only be built with either UHD (for USRP2/B2x0/... devices) or with libusrp/USRP1 support
In recent weeks, we have improved the situation by the following measures:
- Alexander Huemer took the last released libusrp from gnuradio-3.4.2 and released it at http://git.osmocom.org/libusrp/
- Pau Espin packaged this libusrp for Debian, it is now part of our nightly and latest Binary_Packages
- Pau Espin re-structured OsmoTRX to build two binaries from one build:
osmo-trx-uhd and osmo-trx-usrp
As Ubuntu 18.04 (Bionic Beaver) has been released two days ago, Osmocom has enabled Binary_Packages builds for this new distribution in both nightly and latest. As a result, you can now use our binary package feeds on this most recent incarnation of Ubuntu just like on the other supported distributions.
This was relatively easy due to the openSUSE Build Service (OBS) immediately adding support for Ubuntu 18.04. so all we had to o is enable it, and fix up some minor failures. Thanks to OBS for making supporting new distributions very easy!
On April 22nd, Osmocom developer Steve Markgraf has released a new Osmocom project called osmo-fl2k during OsmoDevCon2018.
osmo-fl2k allows you to use the DAC contained in Fresco Logic FL2000 USB 3.0 VGA adapters as a SDR transmitter. Rather than rendering video signals to a screen attached to the VGA output, the DAC is used to generate RF signals in base band, possibly relying on the harmonics to achieve signals at much higher frequencies than possible at 165 MS/s in base-band.
The project thus follows the spirit of the earlier rtl-sdr project, which re-uses USB DVB receiver dongles with the RTL2832U chip as SDR receivers. Like-wise, osmo-fl2k creatively re-uses USB 3.0 VGA adaptors as SDR transmitters. The two projects are thus complementary.
Today, OsmoDevCon2018, the annual Osmocom developer meeting concluded. It featured four days of exciting talks and discussions about open source mobile communications, by developers for developers.
The final schedule containing all 41 individual presentations/discussions/workshops of the four days can be found at https://pretalx.sysmocom.de/osmodevcon2018/schedule/
Thanks to c3voc (the CCC Video team), we have audio+video recordings. Almost all presentations (up to speaker discretion) will be released soon. We will publish another news item once the videos are released.
We'd like to extend our thanks to
- the 20 speakers (at 25 attendees, that's 80%!)
- the sponsor sysmocom for organization, covering all lunch + dinner catering as well as some travel funding
- Lime Microsystems for donating 15 LimeSDR-mini to OsmoDevCon 2018 attendees
- c3voc for their video recording
- IN-Berlin for venue hosting (Sat-Mon)
- CCC Berlin for venue hosting (Fri)
Video recordings of the talks will become available step by step at https://media.ccc.de/b/conferences/osmocon/osmodevcon18
OsmoCon (Osmocom Conference) 2018 is the technical conference for Osmocom users, operators and developers!
We are happy to announce the date of OsmoCon 2018. It has been scheduled on October 18 + 19, 2018 and will happen in Berlin, Germany.
For the second time, the Osmocom Conference brings together users, operators and developers of the Osmocom Open Source cellular infrastructure projects, such as OsmoBTS, OsmoBSC, OsmoSGSN, OpenGGSN and others.
Join us for two days of presentations and discussions with the main developers behind Open Source Mobile Communications, as well as commercial and non-profit users of the Osmocom cellular infrastructure software.
You can find some initial information in our wiki at OsmoCon 2018, which will be updated as more information becomes available.
Call for Participation¶
We're also at the same time announcing the Call for Participation and call on everyone with experiences to share around the Osmocom member projects to submit talks, workshops, discussions or other proposals.
We are particularly looking for contributions about:
- updates on features/functionality/status of individual Osmocom projects
- success stories on how Osmocom projects are deployed in practice
- migration from OsmoNITB to the post-NITB architecture
- tutorials / workshops on how to setup / analyze Osmocom projects
- statistics, reporting, operations aspects of Osmocom projects
- third-party open source utilities to be used with Osmocom projects
OsmoDevCon has successfully introduced the (obviously free/open source software) pretalx conference planning system for the schedule planning of the upcoming OsmoDevCon2018 conference.
All participants of OsmoDevCon submitting a talk have been receiving e-mails asking to confirm their respective talks/workshops using a confirmation link to the pretalx website.
We are planning to use pretalx for other upcoming events and would like to extend our thanks to the pretalx developers!
