Redmine theme
by Вадим Яницкий 08 Mar '16

08 Mar '16

Dear all, I suggest to change a stock Redmine theme to something more beautiful, for example gitmike: https://github.com/makotokw/redmine-theme-gitmike which used by srlabs.de and looks like pretty. Furthermore, the Osmocom logo will look better on light background. Opinions? С наилучшими пожеланиями, Яницкий Вадим.

toolchain problem
by fotos-aller-art＠web.de 05 Mar '16

05 Mar '16

Hallo zusammen, ich wollte toolchain auf meinem Backtrack5r3 als VM installieren, dabei sind Fehler aufgetreten die ich nicht verstehe. Wie kann ich da Abhilfe schaffen? Bis hierhin war noch alles gut. GNU ARM toolchain This page will describe the procedure for compiling a GNU ARM toolchain. We will build a toolchain consisting of: * GCC 4.8.2 * Binutils 2.21.1 * Newlib 1.19 Getting the buildscript First of all, create a directory you want to use for building the toolchain, and download the buildscript <http://bb.osmocom.org/trac/raw-attachment/wiki/GnuArmToolchain/gnu-arm-buil d.3.sh> gnu-arm-build.3.sh there. You will need to make it executable: $ chmod +x gnu-arm-build.3.sh Dependencies In order to build the toolchain, you will need to install the following packages (assuming you're using a Debian-based distribution): $ sudo apt-get install build-essential libgmp3-dev libmpfr-dev libx11-6 libx11-dev texinfo flex bison libncurses5 \ libncurses5-dbg libncurses5-dev libncursesw5 libncursesw5-dbg libncursesw5-dev zlibc zlib1g-dev libmpfr4 libmpc-dev Preparation Open a shell in the directory of gnu-arm-build.sh and create the following directories: $ mkdir build install src Download the needed sources to src/: $ cd src/ $ wget http://ftp.gnu.org/gnu/gcc/gcc-4.8.2/gcc-4.8.2.tar.bz2 $ wget http://ftp.gnu.org/gnu/binutils/binutils-2.21.1a.tar.bz2 $ wget ftp://sources.redhat.com/pub/newlib/newlib-1.19.0.tar.gz Building the toolchain $ cd .. $ ./gnu-arm-build.3.sh I will build an arm-none-eabi cross-compiler: Prefix: <YOURPATH>/install Sources: <YOURPATH>/src Build files: <YOURPATH>/build Press ^C now if you do NOT want to do this. Dann kam folgendes, als wenn er Probleme mit den Ordnern hatte. cid:image001.jpg@01D17613.420C17C0 Könnt ihr mir weiterhelfen? Gruß Peseta3

cell re-selection
by Andreas.Eversberg 05 Mar '16

05 Mar '16

hi, i did a lot of resarch and testing on cell selection and re-selection process the last two week. the cell selection process, network selection process (manual and automatic) and mobility management process were already implemented in OsmocomBB a long time, but turned out to be buggy and incomplete. i made test drives to check the process and debugged it. the re-selection process is new. it is used to track surrounding cells while listening to the BCCH of the current cell (camping on a cell). special extension to the layer1 firmare is used to measure neighbour cells. if an neighbour cell becomes 'better', the mobile switches to that cell, depening on different criteria. now it is possible to move with OsmocomBB. the re-selection process is not handover! handover is a process where a phone switches between cells while doing a call. handover is one next step to implement. the process is a little more complex, because it requires not only neighbour cell measurements, but also syncing to them without interrupting the traffic channel. most layer 3 stuff of handover is already implemented. if you like to play and test your moving OsmocomBB, you can check out the "jolly/roaming" branch. it contains the extension to layer1, as well as sim reader and fixes from "sylvain/testing" branch. use both "mobile" and "layer1" firmware from this branch. in order to see some process at VTY, you can do: enable monitor network 1 (continously display the strongest cell and neighbour cells) show ms 1 (to see current states) show neighbour-cells 1 (to see a more detailed current list of neighbours) andreas

omsocombb not receiving calls
by robert steve 04 Mar '16

04 Mar '16

Hi, I would first like to thank all those who participated in this nice project. I recently started working with osmocombb and was able to have it working fine on a motorola c118. However, I noticed that some sim cards can connect normally to the BTS, can make calls and send SMS but can’t receive anything. They simply don't get paged. While for some other sim cards everything seems to be working fine. Does anyone know what might be causing this issue ? thanks, Robert

Can it be done without using LCR ?

Hi, in the osmocom bb mobile.cfg I don't see any posibility to set a fixed Kc encryption key and the tmsi. How could I achieve that osmocom uses my defined Kc and tmsi? cheers, Simian

Look at this strings from your log: <0005> subscriber.c:601 Requesting SIM file 0x2fe2 <000f> sim.c:209 got new job: SIM_JOB_READ_BINARY (handle=00000004) <000f> sim.c:697 go MF <000f> sim.c:241 SELECT (file=0x3f00) <000f> sim.c:187 sending APDU (class 0xa0, ins 0xa4) <000f> sim.c:876 received APDU (len=0 sw1=0x00 sw2=0x00) <000f> sim.c:952 command failed <000f> sim.c:151 sending result to callback function (type=1) <0005> subscriber.c:657 SIM reading failed Maybe something wrong with your SIM? Try another one. Are you at the master branch? С наилучшими пожеланиями, Яницкий Вадим.

Hi, Can someone confirm if the steps described in http://bb.osmocom.org/trac/wiki/flashing are still valid, as I can’t find “loader.e88loader.bin”. I’m using sylvain/testing branch. Best regards, Robert,
