Can I build my own GMR satellite/base station and core network based on open source software (e.g. Osmo-bts) and SDR?

by 1191595017＠qq.com

Dear Osmocom community, I noticed that the OSMOGMR project is mainly about receiving and decoding downlink GMR data. Can I build my own GMR satellite/base station and core network based on open-source software (e.g. osmo-bts) and SDR? GMR is mentioned in the Osmo-bts user manual, but it doesn't say if it is implemented and how to configure it. If Osmo-bts doesn't work, is there any other project to build my own GMR base station and establish a connection with a GMR device? Best regards, Wei

Osmocom discourse as alternative to mailing lists

by Harald Welte

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."

RACH scan

by Johann T.

Hi, I have made some captures on the L-band uplink channels and tried to decode the RACH messages. All four consecutive TCH channels (according to the spot beam) were recorded and a call was made during the recording. I am using the GRC block gmr_rach_scan.grc. I have removed the IQ swap from the graph, as suggested in the mailing list. The sampling rate and samples-per-symbol values have been set to 93.6k and 4, respectively. It ran fine without any errors, but I couldn't see any results either on the wireshark or under /tmp/rach.txt. Maybe I overlooked something here. Any ideas or remarks? Many thanks, Johann

MES to Satellite decoding and A5-1-GMR decrypt

by Tiger Yi

Dear all, Right now I am studing on osmGMR code and try to understand how it works. From the code my understanding and concerns are as below: 1.  It looks like osmoGMR gmr1_rx only analyze and decode downlink(Satellite to MES) messages and data,  am I right?  If there any similar application that can decode both downlink and uplink(MES to Satellite)? Or osmoGMR needs input to implement downlink decode? 2.  A plaintext-decrypt is mentioned in osmoGMR wiki but no detail about how to implement it.   Is there a opensource code for A5-1-GMR? Or any other clue that can understand how plaintext decrypt  A5-1-GMR? Does osmoGMR need input to implemen it? Best Regards, Tiger

Bug (+ patch) for sync_id retrieval code

by Bart Marinissen

Hi, Whilst working with this code, I came across some inconsistent sync-ids. Diving in deeper, I found a bug. It’s probably best explained by the patch itself, (see below) but I will also try and explain it in plain words. In short, when checking which sync_id has the highest correlation, the relevant bit of of the signal (with wiggle room) is correlated against the sync-id pattern into a buffer. This adds the output correlation to the buffer. Then, at the end, it was decided which sync_id was present by looking for the max correlation. In between sync-ids, the buffer was not reset. Hence when checking the last sync_id, the buffer does not hold the correlation between that sync_id and the signal, but the sum of correlations between the signal and all sync_id. Hence the results were very strongly biased towards the later sync_ids. The fix is easy. Clear the buffer before every correlation. See the patch below. The patch should apply to the master branch, I believe the bug exists in most branches though,. In my mind, the change is too trivial to be copyrighted. But for completeness sake, I give the osmocom-gmr project permission to use this patch. Kind regards, Bart Marinissen diff --git a/src/sdr/pi4cxpsk.c b/src/sdr/pi4cxpsk.c index 1ed40e01989bac05ff915ebd811835a60f95f61e..e8ab843a92d90622b64b5a59fcaff9ef4d01fea0 100644 --- a/src/sdr/pi4cxpsk.c +++ b/src/sdr/pi4cxpsk.c @@ -204,12 +204,12 @@ _gmr1_pi4cxpsk_sync_find(struct gmr1_pi4cxpsk_burst *burst_type, goto err; } - memset(corr->data, 0x00, sizeof(float complex) * corr->max_len); - corr->len = w; - /* Scan all possible training sequences */ for (i=0; (i < GMR1_MAX_SYNC) && (burst_type->sync[i] != NULL); i++) { + memset(corr->data, 0x00, sizeof(float complex) * corr->max_len); + corr->len = w; + struct gmr1_pi4cxpsk_sync *csync; float s_toa, s_pwr; float complex s_peak;

OsmoDevCon 2022 ?

by Harald Welte

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?

Few questions about Osmo-GMR

by Anton Minchev

Hello , last week i worked with osmo-gmr projest ,but still have some questions: 1. I need some more info about S band GMR - what sat is this , az / el , what trafic etc. 2. About gmr1 ambe decode - i tried about dozens of .dat files from gmr1 rx live , some give me ! codec errors , some not , but all .wav audio files are scrambled ,speesh is not recognized at all .. is there some clear traffic at all, or all is A5/2 coded ? 3. If all is scrambled where i may find offline tables / H n matrix/,any source that may generate them ? And if i have tables how they will be integrated with existing osmo-gmr ? I see gmr1_gen_mat that generates G/g matrix .. some more info about that .. .G and .g files seems so small .. Thanks in advance !

Dear list , i am still trying to compile the gnuradio blocks for the rach. But the building stops after 52%. Could it be that there is something wrong in the source code?

Decoding example data with osmo-gmr

by Johann T.

Hi, I have been looking into the example data provided by Osmocom as shown in the link below. http://osmocom.org/projects/gmr/wiki/Example_Data I could reproduce the first pcap output (up to the Ciphering Mode Command) for the Voice call using the gmr1_rx_live from the live branch. With the provided Kc, I thought I would be able to reproduce the second pcap (including the call setup). I have modified the sa_tch3.c to include the Kc code. However, I am not able to get the results as shown in the second pcap file. I noticed that in the sa_tch3.c code, there is a ciphering part (marked by "Retry with ciphering") which was disabled. This part of code didn't compile as some variables were not defined. Probably my approach was not right. Any pointer here? Which code is needed to produce the second pcap (deciphered) file given the Kc is known? Many thanks in advance. Best regards, Johann

OsmoDevCon / COVID-19

by Harald Welte

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.

Osmocom scheduled outage on *2020-07-19 9am CEST*

by Harald Welte

There is an urgent need to migrate our most important public infrastructure to a new server, and I will be doing that on *Sunday, July 19 2020*, starting about 9am CEST. The migration involves redmine (main osmocom.org website), jenkins, gerrit, git, and cgit. In theory, the migration should be quick. I would expect (significantly) less than one hour of downtime. However, we all know Murphys law. Services not affected are mail (including mailman lists), ftp, dns. So in case of doubt, we can still use mailing lists to communicate. In case anyone urgently needs osmocom source code on Sunday morning during the downtime: There are public mirrors available on github.

Thuraya ARFCN

by Johann T.

Dear all, In the past weeks, I have been playing with the Osmocom GMR code. The code has been successfully compiled and installed. My intention is to listen to the broadcast channel of Thuraya in the Netherlands. There are two spotbeams for NL namely 288 and 289. As I am located at the border of the two beams, I have tried both options. So far I couldn't see anything decoded in Wireshark. I noted that the translation of ARFCN to frequency is slightly different in the formula by Driessen (Practical cryptanalysis of the real world systems) and in the ETSI standard (TS 101 376-5-5). There is a shift of half of the channel bandwidth (31.25 kHz). For your information, I am using Ubuntu 16.04, USRP B210, a wideband antenna and LNA with about 20 dBi gain on L-band. As mentioned by Sylvain in the mailing list, the gmr_multi_rx.py is obsolete. I am using the gmr1_rx_sdr.py for my tests. I ran the following commands (one each time) and with Wireshark listening to lo interface while applying the gmr1.bcch filter. Is this the right approach as I don't see anything show up so far? Did I overlook something here? Spotbeam 289 (ARFCN 1007) ./gmr1_rx_sdr.py -s 10000000 -B L -f 1556484375 -a 1007 -g 45 (Driessen) ./gmr1_rx_sdr.py -s 10000000 -B L -f 1556468750 -a 1007 -g 45 (ETSI) Spotbeam 288 (ARFCN 267) ./gmr1_rx_sdr.py -s 10000000 -B L -f 1533359375 -a 267 -g 45 (Driessen) ./gmr1_rx_sdr.py -s 10000000 -B L -f 1533343750 -a 267 -g 45 (ETSI) Comments or suggestions are much appreciated. Many thanks in advance. Best regards, Johann

Hello Thanks to *mohamed yehia* for great help in understanding in osmo-gmr project . In wireshark I saw "immediate assignment" are displaying a different ARFCN than one I was listen too . That means that TCH3 channel is on another ARFCN . What is the way to follow both ARFCN ? I didn't find the ./gmr_multi_rx utility on git (wiki says : ./gmr_multi_rx --gmr1-dl 941 942 -a RX2 -S B:0 -T 10 -is kc extrat the same way as gr-gsm with rainbow tables ? thanks --

Generator matrix used for TCH3 channel encoding

I am interested in finding the generator matrix used for TCH3 channel encoding (GEO-Mobile Radio Interface). I followed the installation steps indicated in OsmocomGMR. There was an example for FACCH3 channel to generate the G matrix. I modified the code for TCH3 (shown below) but the output results does not seems correct.

OsmoDevCon 2018 schedule planning

by Harald Welte

Dear Osmocom Community, [please respect the Reply-To and post all follow-up discussion to this to openbsc(a)lists.osmocom.org, so we avoid having long threads cross-posted to several mailing lists.] Like every year in early December, it is time to discuss as schedule for OsmoDevCon in the upcoming year. Note: Ths is about OsmoDevCon, the more private meeting of developers, *NOT* about OsmoCon, the public conference. == When, Who, Where == I propose the following date for OsmoDevCon 2018: April 20 - April 23rd, 2018 * Who: Active developers/contributors of Osmocom projects (as usual) * Where: IN-Berlin, Berlin (as usual) Please let me know ASAP if that proposed date works for everyone who'd want to attend. We can still change it now, but I would want to nail down the date pretty soon. == Format == After the experiment of reducing from 4 to 3 days last year (due to OsmoCon), we will again go for *four days* in 2018. However, we should clearly divide the days in a way that e.g. "GSM/3G" topics are on two days, while SDR+Other topics are on the other days, so people not interested in some topics can skip one or two days, as needed. We could even divide it further like: * 1 day 3GPP RAN (osmo-bts, osmo-bsc, osmo-pcu, virt_phy, fake_trx, ...) * 1 day 3GPP CN (osmo-msc, osmo-hlr, osmo-sip-connector, nextepc, etc.) * 2 days misc Regards, and looking forward to meeting you [again] in 2018, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Planning for OsmoCon + OsmoDevCon

by Harald Welte

[cross-post to many lists, please follow-up-to openbsc(a)lists.osmocom.org] Dear all, time is flying, and I would like to start early with discussions and planning about OsmoCon and OsmoDevCon in 2018. It helps to start early. Side note: We have some pending issues about the events from last year at http://osmocom.org/projects/osmo-dev-con/issues - I've incorporated them in the text below. == OsmoDevCon == For OsmoDevCon, I think it's easy: We keep it as-is. Same procedure as every year, which means: * same venue, same catering options * same concept of 'anyone contributing to Osmocom can apply for registration until all seats are taken' * same idea of inviting some few speaker[s] doing other FOSS mobile communications work to join us The parts that we need to change, IMHO: * don't reduce from 4 to 3 days like last year. Have full 4 days again * sort topics per day / half-day, i.e. have "GSM/UMTS Cellular Infrastructure" days for BTS/BSC/NITB/MSC/HLR/SGSN/GGSN & Co, but then have other days for other projects. This would enable people not interested in the [continued evolvement] of the cellular projects be able to skip those days, or to simply meet in an adjacent room for parallel hacking sessions/discussions * try to be a bit more structured with the schedule in general. The existing approach works for people who attend all the event all day long, but not so well for people with other plans / limited time Any further change requests or topics to discuss? Please note that Pablo Neira has offered to kindly host an OsmoDevCon in Seville (Spain). I've attended a number of netfilter workshops he organized there, and he's doing a great job! However, given the large number of attendees from Berlin (and Germany in general), I think this would make things more complicated, and more expensive for most attendees. If you disagree with that assessment: I'm open for having the discussion, I just thought it's more practical/economic to do it in Berlin. === 10 year Anniversary Party === Given that 2018 marks the 10 year anniversary of Dieter and me hacking with the Siemens BS-11 in 2008, I think the 2018 incarnation deserves some special celebration of some form. I have no concrete idea yet, but for sure we should so something, and it should be at/around OsmoDevCon. And for sure we should have a BS-11 around :) == OsmoCon == The public OsmoCon was welcomed and was a success. However, let's start this discussion with a review of last years event. === Registration === * Registrations came in way too late. Two weeks ahead of the event, we were considering to cancel it. And then within the last few days, we had to turn people down due to limited seating capacity * To make planning more reliable, we see on other option but to significantly raise the registration fee combined with an equally significant discount for early booking === Duration === * Many people requested multiple days rather than just one, in order to make more out of (long distance) travels. This is obvious, but as we had no idea how many people would attend at all (or if we have to cancel due to lack of attendance), planning multiple days in the first incarnation would have been high risk and a multitude of work * I would suggest to expand to two or even three days this week, possibly one days with tutorials and the other day with tech talks * Slightly less crammed schedule due to multiple days === Venue === We recognize this yearso venue was not the best option, due to * Bad ventilation in the basemenet * Difficult to find * No space next to the conference room where people can meet / hang out in parallel to talks (not everyone attends every talk) I still like the "understatement" of the venue. I'd prefer any hostel / non-profit / hackerspace / university over luxurious hotels any time. Going to an expensive venue means more or less automatically more expensive ticket fees, which again is more likely to exclude pure community members without a commercial activity related to Osmocom. So any future venue would ideally: * be able to hold slightly more people than this year * have a second room or large lobby in which people can meet for extended coffee breaks in parallel to some talks, as needed * be slightly easier to find (and we have to put up some signs outside and in the lobby) * have better WiFi and/or wired connectivity === Programme / Format === * less crammed over multiple days * some more "interactive" formats were requested, for users to provide feedback to developers * there was some discussion about topics / speakers in redmine last year, but not too much participation [until it was too late]. * I'd suggest a more formal CfP process with a submission deadline that allows us to publish a preliminary schedule long ahead of the event === Video Recordings === I think they were a big success, and it was a very big surprise that the CCC Video Operations Center was volunteering to help such a small and niche-interest event like OsmoCon. We should make sure that we can repeat this for 2018. == Dates / Frequency == Having OsmoCon and OsmoDevCon back to back becomes somewhat long, if OsmoCon is 2-3 days and OsmoDevCon is 4 days. Basically we're looking at a full week for those of you who would like to attend both events. But then, I think the number of people attending both events is actually not all that big. Without checking the details, I think not more than half of the OsmoDevCon attendees were attending OsmoCon. I would expect that tendency to remain or even increase. I still think it's good to keep them back-to-back. In terms of frequency, I would actually suggest we move to a 6-month cycle rather than a 12-month cycle. There's a lot of development going on at all time. I understand that not everyone is able to attend two events just on Osmocom, especially if it's a spare time / hobby type activity. That's ok, I think there's no problem with attending either of the two only, and catching up by video recordings and/or mail on the other. The qeustion is: Should that second event be developer-oriented or user-oriented? Or again both? Any comments here? Ok, that was a somewhat lengthy e-mail. Please make sure to provide any feedback you may have as early as possible, to increase the chances of your feedback being reflected in the planning.

git.osmocom.org cgit improvements

by Harald Welte

Hi all, today I've deployed some cgit improvements on https://git.osmocom.org/, in the hope that it makes this tool even more useful: 1) syntax highlighting of source code (requested by Hoernchen) The source code is now highlighted by pygments. I don't really understand why somebody would want to look at source code a lot in a browser, but well, it was as easy as to enable the existing pygments based filter plugin. 2) rendering of "about" page from README.md As you might have noticed, I've introduced a README.md in a number of repositoires, and cgit is now rendering an about page for every repository, e.g. at http://git.osmocom.org/libosmo-abis/about/ 3) gerrit change-ID hyperlink generation All gerrit Change-IDs in commit messages are now automatically converted to hyperlinks to the respective gerrit change, see e.g. the below example: http://git.osmocom.org/openbsc/commit/?id=6dd0fc685b7149f67a5fe17a5bce55c44… Please note that this works for the "Change-Id" line of the actual change, but also for change-ids in the free text (e.g. "this depends on change-id ... in libosmocore") 4) Osmocom ticket/issue hyperlink generation Any Line that matches the "^((Relate|Close|Fixe)[ds]):" prefix is scanned for occurrences of "OS#(\d+)" which are then amended with hyperlinks to the respective issue on osmocom.org Please note the OS# prefix is mandatory, so things like "OS#1614, 1615" will not work, as can be seen at http://git.osmocom.org/osmo-pcu/commit/?id=0a8fae8d141c2cfa4387ffe9b35402d5… Please format your commit messages accordingly.

RFC: OsmoDevCon 2017 planning

by Harald Welte

Dear Osmocom Community, [please respect the Reply-To and post all follow-up discussion to this to openbsc(a)lists.osmocom.org, so we avoid having long threads cross-posted to several mailing lists.] >From 2012 to 2016 we were running a series of small, invitation-only Osmocom Developer Conferences. Access was intentionally restricted to those community members who have demonstrated an existing track record of contribution to any of the projects under the Osmocom umbrella. This format of a small, tightly knit group of about 20 people has been successful over the years, and I have received a lot of positive feedback from past participants. On the other hand, the Osmocom project has grown in scope and diversity, and some of those projects don't have all that much relationship to each other - except being started by people from within the same group. There's the cellular communications (GSM/GPRS/EDGE/UMTS and hopefully at some point LTE) protocols which is attracting a lot of professional users. And then there's pure community projects like rtl-sdr, OsmocomBB, OsmocomGMR and many other efforts. Particularly the cellular infrastructure projects (OsmoBTS, OsmoPCU, OsmoBTS, OsmoNITB, OsmoSGSN, OpenGGSN, OsmoIuh & co) are somehow "standing out" of the othe projects in the context of having a wider user bsae, and in that user base also primarily commercial users. So I'd like to start a discussion on how to possibly change the event format to accomodate the various interests and parties. I definitely don't want to loose the "annual meeting of old friends" atmosphere, while at the same time also opening up to other interested parties. One idea would be to keep OsmoDevCon as-is and have a separate event where non-contributing/developing users / sysadmins / system integrators could also be attending. Another idea would be to split into a 'user day' and 'developer days' format. This is something the netfilter developer workshops have been using for many years, and from my limited insight quite successfully so. The "user day" is more like a traditional tech conference, with a large auditorium and talks oriented towards users / sysadmins / integrators of the software. The "developer days" are the invitation-only part, for known contributing developers only, similar to what we have at OsmoDevCon. Having both events (or both parts of an event) back-to-back has the advantage that a large number of potential speakers for the 'user day' are already present, and they don't have to travel yet another time. One could even structure it further and say we have one user day, one public 'Osmocom cellular developer day' and then the closed 'OsmoDevCon classic', maybe reduced from 4 days to 3 or even 2 days only? What is the general opinion about this? Are there people lurking on this list who would be interested in attending a public 'user day' or even 'developer day' about the Osmocom cellular projects, with presentations and workshops around topics such as running Osmocom based cellular networks? In terms of when/where, I would suggest to keep the tradition of April in Berlin/Germany. But I'm of course very happy if somebody wants to host it some place else... Regards, and looking forward to meeting you [again] in 2017, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Moving from trac to a single redmine

by Holger Freyther

Hi guys, I think some of us would like to move to redmine and start using public tickets more frequently. So in case we move there are some topics to be discussed and I would like to start with a couple of them right now. Tickets: Redmine has a global linear sequence of ticket numbers. If we move from many tracs to a single redmine we can either: * not import tickets * only import from one project * deal with changing ticket numbers In terms of installations the GMR trac is broken in regard to tickets, there are some for SDR that are probably not being fixed anytime soon, baseband might be relevant and OpenBSC is unlikely to be relevant. I don't think we have ever used ticket reference in OpenBSC commit messages so in terms of OpenBSC having changing ticket numbers would not be a big deal. E.g. we could add a custom field with the old trac number? Wiki: We have external references that should be redirected to the new place. Is there any way besides maintaining a list in the apache2/nginx configuration and making redirects as we find broken references? Can we proactively manage this? Is anybody willing to come up with a script and nginx configuration for doing this? kind regards holger

Time to rename projects.osmocom.org to osmocom.org

by Holger Freyther

Hi, I think we all liked tnt's proposal to just call it osmocom.org. Are we ready to make the redmine available as osmocom.org (and redirect www.osmocom.org, projects.osmocom.org to it)? As first step of redirects I propose: http://bb.osmocom.org/ -> http://osmocom.org/projects/baseband http://openbsc.osmocom.org/ -> http://osmocom.org/projects/openbsc http://tetra.osmocom.org/ -> http://osmocom.org/projects/tetra http://simtrace.osmocom.org/ -> http://osmocom.org/projects/simtrace http://security.osmocom.org/ -> http://osmocom.org/projects/security http://gmr.osmocom.org/ -> http://osmocom.org/projects/gmr http://sdr.osmocom.org/ -> http://osmocom.org/projects/sdr any objections or corrections to that? kind regards holger

[RFC] [ADMIN] Making lists subscriber-only?

by Harald Welte

Dear all, so far the osmocom.org mailing lists have always been in a 'non-members are manually moderated' mode. This has created a lot of work for manual list moderation, where a lot of the messages caught are simply spam, and only the occasional valid message is being received. I'd like to thank the list moderators for taking care of this. However, in more recent discussions, we were considering to move the lists to a completely closed mode, i.e. postings would automatically be rejected from non-members. The automatic response would contain a description of how to subscribe in 'nomail' mode, i.e. to subscribe in a way to be able to post to the list, while still not receiving any incoming traffic. The latter should be fine for occasional posters who don't want the bulk e-mail that goes with a full/regular subscription. Please provide feedback in case you disagree with that change. Unless there is major opposition, we will likely transition to the 'closed' mode within one month.

[ANNOUNCE] OsmoDevCon 2013-04-04 till 2013-04-07, Berlin

by Harald Welte

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.

I managed to set up Osmogmr successfully but when I fired it up using the following commands, I receive the following error. tyrus@jedi-council:~/gmr_multi_rx$ ./gmr_multi_rx --gmr1-dl 941 -a RX2 -S A:0 --addr=usrp2 -T 10 linux; GNU C++ version 4.4.5; Boost_104200; UHD_003.004.002-159-g0d5cef73 Given gmr1-dl ARFCNs: 941 = 1554.406250 MHz Required bandwidth is: 31.250000 kHz Creating the UHD device... -- Opening a USRP2/N-Series device... -- Current recv frame size: 1472 bytes -- Current send frame size: 1472 bytes *terminate called after throwing an instance of 'uhd::runtime_error'* * what(): RuntimeError: fifo ctrl timed out looking for acks* Aborted I'm running off USRP N200 with a WBX board with UHD version 003.004.002-159.

Re: a question

by Sylvain Munaut

Hi, Please ask your questions on the mailing lists preferrably. I've redirected this mail to it because it doesn't contain any sensitive info and the response can be useful to others. > I have learned a lot of things from your articles about GMR-1-A5. Thanks. But if you mean the http://gmr.crypto.rub.de/ , I'm not the author :) > But i have a question,Why you say that "DALMA V2.0 (might be AMBE codec > IC)"? This is incorrect. The picture and embedded 'text' dates back from before we knew what that chip was and we thought it might be the CODEC chip. This turned out to be incorrect, it's just an ASIC that does the timing sensitive part of the radio modem and some signal processing. > Maybe the ambe codec is accomplished in TMS320C55x of the OMAP IC. Yes, we know it is in the OMAP DSP. But unfortunately the code is not that small and not really easy to read. If you want to give it a shot and try to find it, please go ahead, that'd be a great help :) Cheers, Sylvain

Re: osmo-gmr build error

by Dimitri Stolnikov

Hi Miguel, my guess it's gnuradio related problem as they have changed gr_top_block interface recently. Which version of gnuradio are you using? Try replacing the line boost::thread fg_thread( boost::bind( &gr_top_block::run, fg.get() ) ); with boost::thread fg_thread( boost::bind( &gr_top_block::run, fg.get(), 100000 ) ); Best regards, Dimitri On Thu, 09 Feb 2012 20:29:26 +0100, David <kktmp1(a)gmail.com> wrote: > Same error here... > > Any ideas ? > > Is this list alive ? > > BR. > > nadie@Home1:~/osmoGMR/osmo-gmr/utils/gmr_multi_rx$ make TARGET=fcd > > g++ -Wall -Wextra -Wno-unused -O2 -DHAVE_FCD -I/usr/local/include > -I/usr/local/include/gnuradio -c -o gmr_multi_rx.o gmr_multi_rx.cpp > In file included from /usr/include/boost/mem_fn.hpp:22:0, > > from /usr/include/boost/bind/bind.hpp:26, > from /usr/include/boost/bind.hpp:22, > from gmr_multi_rx.cpp:65: > /usr/include/boost/bind/mem_fn.hpp: In member function ‘R& > boost::_mfi::dm<R, T>::operator()(T*) const [with R = void(int), T = > gr_top_block]’: > /usr/include/boost/bind/bind.hpp:243:60: instantiated from ‘R > boost::_bi::list1<A1>::operator()(boost::_bi::type<R>, F&, A&, long int) > [with R = void (&)(int), F = boost::_mfi::dm<void(int), gr_top_block>, A > = > boost::_bi::list0, A1 = boost::_bi::value<gr_top_block*>]’ > /usr/include/boost/bind/bind_template.hpp:20:59: instantiated from > ‘boost::_bi::bind_t<R, F, L>::result_type boost::_bi::bind_t<R, F, > L>::operator()() [with R = void (&)(int), F = boost::_mfi::dm<void(int), > gr_top_block>, L = boost::_bi::list1<boost::_bi::value<gr_top_block*> >, > boost::_bi::bind_t<R, F, L>::result_type = void (&)(int)]’ > /usr/include/boost/thread/detail/thread.hpp:61:17: instantiated from > ‘void boost::detail::thread_data<F>::run() [with F = > boost::_bi::bind_t<void (&)(int), boost::_mfi::dm<void(int), > gr_top_block>, > boost::_bi::list1<boost::_bi::value<gr_top_block*> > >]’ > gmr_multi_rx.cpp:540:1: instantiated from here > /usr/include/boost/bind/mem_fn.hpp:342:23: error: invalid use of > non-static > member function > > make: *** [gmr_multi_rx.o] Error 1 > > > > > > > On Wed, Feb 8, 2012 at 6:20 PM, Miguel h <miguelh(a)rebels.com> wrote: > >> I am trying to build osmo-gmr following instructions from >> http://gmr.osmocom.org/trac/**wiki/GettingStarted<http://gmr.osmocom.org/trac/wiki/GettingStarted>, >> everything went fine until making gmr_multi_rx, same error in Ubuntu >> 10.10 32bit and Ubuntu 11.10 64bit. >> >> Any ideas on fix this? >> root@signals:~/osmo-gmr/utils/**gmr_multi_rx# make TARGET=fcd >> g++ -Wall -Wextra -Wno-unused -O2 -DHAVE_FCD -I/usr/local/include >> -I/usr/local/include/gnuradio -c -o gmr_multi_rx.o gmr_multi_rx.cpp >> >> In file included from /usr/include/boost/mem_fn.hpp:**22, >> >> from /usr/include/boost/bind/bind.**hpp:26, >> >> from /usr/include/boost/bind.hpp:**22, >> >> from gmr_multi_rx.cpp:65: >> >> /usr/include/boost/bind/mem_**fn.hpp: In member function ‘R& >> boost::_mfi::dm<R, T>::operator()(T*) const [with R = void(int), T = >> gr_top_block]’: >> >> /usr/include/boost/bind/bind.**hpp:243: instantiated from ‘R >> boost::_bi::list1<A1>::**operator()(boost::_bi::type<R>**, F&, A&, long >> int) [with R = void (&)(int), F = boost::_mfi::dm<void(int), >> gr_top_block>, >> A = boost::_bi::list0, A1 = boost::_bi::value<gr_top_**block*>]’ >> >> /usr/include/boost/bind/bind_**template.hpp:20: instantiated from >> ‘typename boost::_bi::result_traits<R, F>::type boost::_bi::bind_t<R, F, >> L>::operator()() [with R = void (&)(int), F = boost::_mfi::dm<void(int), >> gr_top_block>, L = boost::_bi::list1<boost::_bi::**value<gr_top_block*> >> >]’ >> >> /usr/include/boost/thread/**detail/thread.hpp:56: instantiated from >> ‘void boost::detail::thread_data<F>:**:run() [with F = >> boost::_bi::bind_t<void (&)(int), boost::_mfi::dm<void(int), >> gr_top_block>, >> boost::_bi::list1<boost::_bi::**value<gr_top_block*> > >]’ >> >> gmr_multi_rx.cpp:540: instantiated from here >> >> /usr/include/boost/bind/mem_**fn.hpp:342: error: invalid use of >> non-static member function >> >> make: *** [gmr_multi_rx.o] Error 1 >> >> --- >> miguelh(a)rebels.com >> >> ------------------------------**------------------------------**---- >> This message was sent using IMP, the Internet Messaging Program, >> part of the Horde framework and provided by HomeFreeMail.com. >> >> >> >>

Sample data

by Sylvain Munaut

Hi, Several people at CCC and by mail have asked for sample data to test osmo-gmr. So I've now uploaded some example .cfile and resulting pcap, you can get them on the wiki : http://gmr.osmocom.org/trac/wiki/Example_Data They only contain broadcast data and tch data from my own phone. If you want to add your own captures, make sure that's also the case ! Cheers, Sylvain

Re: [airprobe-main] [ANNOUNCE] First OsmocomGMR code release

( CC'ing the gmr mailing list since it's probably best to continue there :) >> As some of the readers may already know, a couple of Osmocom developers >> have been working on a new sub-project: OsmocomGMR. >> >> The primary goal of this project is to provide a reusable and clean >> implementation of the various layers of GMR-1. > > Wow! > > In terms of capabilities, would it allow to reach something like making > an opensource phone interfacing to Thuraya Sat network? It's certainly nowhere near that now, but one can always hope :) Since GMR-1 is so close to GSM, al the MM and CC layers of osmocom-bb could probably be re-used easily. The RR is completely different tough. The current code doesn't have the 'modulation' part but that's relatively easy. (all bursts types are described in a structure that contains all the info already to make a proper gmr1_pi4cxpsk_modulate function). Then you'd need a real time interface to USRP which is a bit more complex :) But it's something I'll definitely look into at some point because I'd like to broadcast my own GMR-1 network :p Cheers, Sylvain
