Osmocom discourse as alternative to mailing lists
by Harald Welte 27 Jul '23

27 Jul '23

Dear Osmocom community, while many people with a long history in FOSS development have no issues at all with mailing lists as primary form of engaging with their community, they have undoubtedly fallen out of fashion in favor of various chat/messaging systems or web based forums. In Osmocom, we've just launched an installation of the discourse forum software available at https://discourse.osmocom.org/ providing an alternative to our traditional mailing lists at https://lists.osmocom.org/ We're looking forward to see whether this web-based approach will facilitate more and/or other people to engage with the Osmocom developer/contributor community. Feel free to join and get the discussions started. If there's a need for more categories or sub-categories, just let one of the moderators know and we can help with that. The old mailing lists will continue to remain available for those who prefer them. -- - Harald Welte <laforge(a)osmocom.org> https://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

gr-gsm uplink loop
by Nikos Balkanas 21 Jul '22

21 Jul '22

Hi, I am trying to develop a mobile loop (uplink) for the receiver in receiver_impl.cc. gr-gsm currently synchronizes, finds the start of a burst, using FCHH and SCHH signals. These are all downlink signals. There is no provision for synchronizing to uplink signals. I was wondering if there were any uplink bursts that the receiver could synchronize to. I can try to synchronize with autocorrelation of the training sequence, but I was wondering whether there are any better options out there. Any help would be appreciated. TIA Nikos

OsmoDevCon 2022 ?
by Harald Welte 11 Mar '22

11 Mar '22

Dear fellow Osmocom developers, as you all know, we've sadly had to skip OsmoDevCon 2020 and 2021, trying to compensate it at least to some extent with our OsmoDevCall every two weeks. The COVID-19 pandemic is far from over, and we don't know what the upcoming winter season will bring. Nevertheless, I think it would be a good idea to start a discussion of whether we should plan for an OsmoDevCon in 2022. I personally would say let's plan for the usual late April 2022 time frame, and if the pandemic situation deteriorates, we can still cancel it with something like one month lead time. I would also personally suggest to limit attendance to people who are fully vaccinated, and in addition do a self-test for all participants every morning. In terms of venue, we might also consider to move to a venue that allows better ventilation. Irrespective of the above we can also bring the air filters from the sysmocom office. So with that as an input statement, I would like to hear your opinion on the above proposals. Who would want to attend? Any complaints against the "vaccinated only plus daily self-tests in the morning" approach?

OsmoDevCon / COVID-19
by Harald Welte 05 Sep '20

05 Sep '20

Dear fellow Osmocom developers, as you all know, we've sadly had to postpone OsmoDevCon 2020 back in April this year. At the time, we discussed to re-visit the situation in October 2020. While legally it is no problem at all to host an event with ~ 20 participants in Berlin/Germany (specific regulations really only start from 50+ participants) - I'm not entirely convinced it would be the smartest move. Legality and public health regulations are only one part of the equation - common sense and profound care for the key members of our community for sure are more relevant considerations to me. I'm not 100% in favour and not 100% against. Hence, I would like to get your input. Should we a) try to get an event organized on-site in Berlin? We'd have to move to a larger venue than IN-Berlin with proper ventilation and sufficient space so we can keep physical distance, but I think that's manageable for sysmocom as organizer. b) simply postpone to 2021? I'm convinced the situation will not change significantly (in a positive way) until late April 2021, so it's not really a "solution" as it will likely mean we have to think of late 2021 or 2022. c) plan some kind of online conference? To be honest, I think this model works fine for events where a single speaker wants to give lectures to hundreds or thousands of participants. But OsmoDevCon is much more interactive. We could record or live-stream some talks or screencasts from home, sure. But that only captures one part of the event. We could also try to set a date for a collaborative mumble, or the like - for the "hallway track". What are your thoughts? Let's avoid cross-posting the discussion to all of the mailing lists and simply have it on openbsc(a)lists.osmocom.org.

gr-gsm via pybombs error
by Wilfredo Hernandez 04 Jun '20

04 Jun '20

Hi, I am having issues installing gr-gsm through pybombs on Ubuntu 20.04. GNURadio 3.8 was installed using the Nuand/BladeF Install guide (Link Below). From there I used the link for gr-gsm (link below) to install it using pybombs and using the same bladerf prefix. After installing a couple dependencies, I recieve the following error: (Attached to this message is the CMake Error log and CMake output log as well). Cloning into 'gr-gsm'...

installation issue
by MG - SMS ARSIA 21 Jan '20

21 Jan '20

Hello, I would like to install gr-gsm but I have some problems. I give you some information about the installation tries: 1. OS Ubuntu 14.04 2. version of gnuradio : 3.6.5.1 (the one compatible with Ubuntu 14, do you propose another version?) 3. I follow the instructions on https://osmocom.org/projects/gr-gsm/wiki/Installation. I used two methods * for ubuntu 16 (?) but during the build I have a fatal error: "fatal error : gnuradio/attributes.h not found" in api.h there is a header file named "attributes.h" in my gnuradio installation, maybe I should "connect it" in the file? * I tried with Pybombs, but it's so difficult and I obtained many dependencies problems 1. I installed libosmocore from the source Thanks you for your help Best regards, MG

Dear fellow Osmocom developers, I'm a bit surprised to notice that not more people have signed up for OsmoDevCon 2019. I guess it was mostly an oversight when the date was originally announced, and not a lack of interest? ;) All details about the event are available at the related wiki page at: https://osmocom.org/projects/osmo-dev-con/wiki/OsmoDevCon2019 Please enter your name at https://osmocom.org/projects/osmo-dev-con/wiki/OsmoDevCon2019#Requested in case you would like to attend.
