To generate that binary, you first need to build and install latest LimeSuite master [1], and then build osmo-trx with --with-lms configure flag. As you are building for raspberry pi3, you may want to enable instruction set optimizations as explained in the user manual section "12 OsmoTRX hardware architecture support" [2]. Have a look at the wiki page too for further information [3]. Also a reminder: we have osmo-trx-lms already available as a debian package for debian9 [4], but I think we don't enable NEON on that build.

Multiple osmo-trx-xxx
by Antony Lemmens 12 Jul '18

12 Jul '18

Hello, I am trying some setup to have multiple channels working all together: I have an UmTRX and a LimeSDR boards working fine. The problem is that I cannot launch osmo-trx-uhd and osmo-trx-lms at the same time as the VTY TCP port are defined in libosmocore. Is it a way of disabling the VTY or change the TCP port it listen to? Have a nice day, Antony

Multi-arfcn multiplexing over same physical channel
by Antony Lemmens 12 Jul '18

12 Jul '18

Hi there, I'm really happy to make my LimeSDR working with the master branch, good job guys! I'm now trying to enable the multi-arfcn multiplexed over one physical channel but I do not succeed to have it working (No response from transceiver for phy0.1 (CMD RXTUNE 894000)). Do I need to configure or pass some parameters (see further for what I'm doing)? I am starting osmo-bts-trx with "-t 2" option, and here is the extract of part of my configuration file: ----- osmo-trx-lms.cfg trx multi-arfcn enable swap-channels disable egprs enable tx-sps 4 rx-sps 4 chan 0 tx-path BAND1 rx-path LNAW ----- osmo-bts-trx.cfg phy 0 instance 0 osmotrx rx-gain 10 phy 0 instance 1 osmotrx rx-gain 10 bts 0 band 900 trx 0 phy 0 instance 0 trx 1 phy 0 instance 1 ----- osmo-bsc.cfg bts 0 type sysmobts band GSM900 trx 0 arfcn 10 trx 1 arfcn 20 Thanks in advance, Antony

cancellation of build1.osmocom.org

Hi! We've not used the old build1.osmocom.org machine since late April, so I am finally pulling the plug and cancelling the contract as of tomorrow. I manually looked around and the only parts that looked worth backing up was ~osmocom-build/neels which I've now copied over to build2.osmocom.org:~root/neels/from_build1/ Regards, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

osmo-bsc refactoring / inter-BSC handover
by Neels Hofmeyr 02 Jul '18

02 Jul '18

Good morning, I wanted to get inter-BSC handover complete before today, and worked like a maniac for the last two weeks. I'm looking forward to your comments on the osmo-bsc rework, which started so small and rippled through the entire code base like a flash flood. I hope you will find review of it not too daunting, it fully qualifies as a code bomb. It is refactoring no less than: - dynamic timeslots, - lchan states from allocation through release, - assignment, - handover - handling of MGW endpoints, and - the conn FSM. - gsm_network->T123 timer handling, - the way a BTS's neighbors are configured, - handover and assignment rate counters, - and whatnot. - adding five new FSM implementations to osmo-bsc, - and actually adding inter-BSC Handover, both sides (almost). Of course I couldn't wrap things up completely, but the good news is that the only problem left now is that I can't get a ttcn3 test written for inter-bsc MT handover [1]. Consider the MT side broken yet, though it should be small fixes. So the refactoring is done and all ttcn3-bsc-tests pass. Yes, *all*! I will now submit the patches to gerrit; some though could want to go to libosmocore, and for some other "neat" inventions of mine I'm watching the comment space in curiosity. I did try to separate some changes into individual commits, but the final chunk is too inter-related to pull it apart without spending huge amounts of time to make osmo-bsc work for each intermediate state. I feel both like saying "sorry" and "you're welcome" about this at the same time. Sorry about the size of the single patch; but a lot of code got extremely easier to read and follow, and a lot safer too, into a nicer osmo-bsc future. ~N [1] I have a marginal test added for inter-bsc MO, but the inter-bsc MT gets me. The problem there is that it is the first time a conn is initiated by the MSC side. I can get that to work by using BSSAP on that Test_CT. It goes well up to the point where osmo-bsc sends MGCP CRCX and expects a response. Now I want to use the MSC_ConnHdlr to manage MGCP, but I can't for the life of me figure out how to be able to do both at the same time. I tried for very long to resolve "BSC_Tests.ttcn:2755.13-2756.31: error: Message type `(a)BSSAP_CodecPort.BSSAP_N_CONNECT_req' is not present on the outgoing list of port type `(a)BSSMAP_Emulation.BSSAP_Conn_PT'" but it feels like a brick wall... It's the final thing before I can say: I'm done, take a look at inter-BSC HO.

osmo-bsc with remote osmo-stp.
by Andrew Back 21 Jun '18

21 Jun '18

Hello, I've had success with running a NITB based on the new architecture fine when everything is on one host. However, I'd now like to split this across multiple hosts. I have one host dedicated to running osmo-stp and this appears to bind to the IP specified. However, the instance of osmo-bsc running on another host always fails to connect and I think, despite configuring to use a remote STP, it's trying localhost. Packages installed from Debian 9.0/latest repo. Configs and osmo-bsc output below. Any pointers as to where I'm going wrong would be much appreciated.

Hello. I have some problems.I want to create a GSM network for my final diploma project for University.I'm using USRP2 and I haven't find any specific configuration files for this type of USRP.Do you have any configuration files for USRP2? I'm running Kali Linux (amd64). I've attached the config files that I've used from osmocom.org and some printscreens.Sorry for my English.I'm looking forward for your response.Thank you!

Hi, sorry for my English. I installed osmocombb on Kali rolling. When i'm trying to start my own bts, it works for 4 seconds, then i can see message "Shutdown timer expired". Bellow you can see my config files. 1 screenshot - 2 trx firmware on motorola c115. 2 screenshot, left - follow the commercial BTS timer, right - starting MSC, SMS, HLR. 3 screenshot - starting osmo-bts. 4 screen - my problem. I can connect with telnet to BSC and BTS, but BTS - only for this 4 seconds, when it's up. I didn't replaced filters on motorola, is it my problem? Or i just need to install smth more?

Regarding Programming SIM cards
by Ferdaus, Farah 13 Jun '18

13 Jun '18

Hi there, I have built and installed the requirements for OpenBTS and my USRP (Ettus N210) is responding but now I am stuck at SIM card stage. I am trying to program a Super SIM 16-in-1 using the Insten_USB_SIM_Card_Writer<https://www.amazon.com/Insten-Reader-Writer-Backup-Phone/dp/B0188GHIP2/ref=…> and following the steps mentioned here<http://openbts.org/w/index.php?title=ProgrammingSIMcards> and here<http://osmocom.org/projects/pysim/wiki> but unable to write the sim card. Every time I run the pcsc_scan command it stops working. Below is the output. "wslopenbts@wslopenbts-desktop:~$ pcsc_scan PC/SC device scanner V 1.4.25 (c) 2001-2011, Ludovic Rousseau <ludovic.rousseau(a)free.fr> Compiled with PC/SC lite version: 1.8.14 Using reader plug'n play mechanism Scanning present readers... Waiting for the first reader...^C" The problem seems that the PC is not getting the SIM card reader. But the SIM card reader was plugged into the PC while running the command and the LED turned red which indicate it was getting the power from the PC. Do you think, buying another new SIM card reader can resolve the issue? I can test by buying another SIM and SIM card reader; Do any of you have any suggestion for the SIM and SIM card reader, particularly which one will be good? Finally, any guideline for me regarding programming the SIM card. I will be very grateful if you help me by giving suggestions to resolve my issue. Can anyone please help me regarding this issue. Thanks in advance Best Regards, Farah
