Hello there, Could anyone help me with the following, please: Is there any way to monitor baseband via OS? I.e. when the GSM modem receives some communication from the network and such communication is "addressed" to SIM (e.g. RAND), can we use OS to either (a) "see" that communication from the network, or (b) at least know that some communication of certain type was received by the modem and passed on to SIM? Many thanks in advance for your time and consideration! Alexander

Thanks again, I am still getting the NACK most of the times or it get stuck after it finishes the downloading, but with "-i 10" option I had the layer1.compalram. bin loaded. It's fantastic! For the first time I got something showing on the phone screen! Now I have another problem that is very silly but it is making me crazy. I cannot find the layer23 app! Does it still exists or has it been replaced?

Thank you Sylvain and Dario! It was a cable problem, I bought a usb one and It works, the only problem is that now I get a NACK, I read it could be a timing problem and I tried to comment the printf as suggested in a recent post, but it did not work. This is what happens: loretta@loretta-laptop:~/osmocom-bb/src/host/osmocon$ ./osmocon -p /dev/ttyUSB0 -m c123xor ../../target/firmware/board/compal_e88/hello_world. e88loader.bin got 2 bytes from modem, data looks like: 2f c8 /. got 5 bytes from modem, data looks like: 1b f6 02 00 41 ....A got 1 bytes from modem, data looks like: 01 . got 1 bytes from modem, data looks like: 40 @ Received PROMPT1 from phone, responding with CMD read_file(../../target/firmware/board/compal_e88/hello_world.e88loader.bin): file_size=19560, hdr_len=4, dnload_len=19567 got 1 bytes from modem, data looks like: 1b . got 1 bytes from modem, data looks like: f6 . got 1 bytes from modem, data looks like: 02 . got 1 bytes from modem, data looks like: 00 . got 1 bytes from modem, data looks like: 41 A got 1 bytes from modem, data looks like: 02 . got 1 bytes from modem, data looks like: 43 C Received PROMPT2 from phone, starting download handle_write(): 1023 bytes (1023/19567) handle_write(): 768 bytes (1791/19567) handle_write(): 768 bytes (2559/19567) handle_write(): 768 bytes (3327/19567) handle_write(): 768 bytes (4095/19567) handle_write(): 768 bytes (4863/19567) handle_write(): 768 bytes (5631/19567) handle_write(): 768 bytes (6399/19567) handle_write(): 768 bytes (7167/19567) handle_write(): 768 bytes (7935/19567) handle_write(): 768 bytes (8703/19567) handle_write(): 768 bytes (9471/19567) handle_write(): 768 bytes (10239/19567) handle_write(): 768 bytes (11007/19567) handle_write(): 768 bytes (11775/19567) handle_write(): 768 bytes (12543/19567) handle_write(): 768 bytes (13311/19567) handle_write(): 768 bytes (14079/19567) handle_write(): 768 bytes (14847/19567) handle_write(): 768 bytes (15615/19567) handle_write(): 768 bytes (16383/19567) handle_write(): 768 bytes (17151/19567) handle_write(): 768 bytes (17919/19567) handle_write(): 768 bytes (18687/19567) handle_write(): 768 bytes (19455/19567) handle_write(): 112 bytes (19567/19567) handle_write(): finished got 1 bytes from modem, data looks like: 1b . got 1 bytes from modem, data looks like: f6 . got 1 bytes from modem, data looks like: 02 . got 1 bytes from modem, data looks like: 00 . got 1 bytes from modem, data looks like: 45 E got 1 bytes from modem, data looks like: 53 S got 1 bytes from modem, data looks like: 16 .

Any plan to fork OpenBTS and/or merge with Osmocom code?
by Fabio Pietrosanti (naif) 11 Apr '11

11 Apr '11

Hi all, this email don't want to be a provocative email but just an opinion related to the creation of value for GSM TLC stack into the opensource environment. As we know currently there are several different projects growing into the GSM (then tetra and in future 3G?) opensource ecosystem. The first "pratical" base has been OpenBTS as a simplified GSM um interface for VoIP. The second major implementations was around the osmocom project that build-up a complete and well designed GSM stack with all the modular interfaces and protocols for communications between BTS and BSC, with MSC, HLR, GGSN, SGSN and major GSM network components. Additionally, if i understood correctly osmocom is much more advanced with broad scope and better design than OpenBTS. It seems to me that OpenBTS it's almost stalled due to the "commercial fork" of the OpenSource project and only fairwaves is contributing to the opensource branch. I personally really dislike the "Commercial fork" approach where the community is used only in the early phase of the project to improve it and from a certain point the community doesn't get almost any added value. I like much more the dual-licensed approach like AGPL/Commercial (like http://pjsip.org) where all the value of the code is publicly released. However, my post was related to a question: - How complex would be, leveraging existing public OpenBTS code, to integrate into the Osmocom project? I mean, having a sort of lightweight BTS component speaking A-Bis over IP to OpenBSC like the cheap nano ip.access BTS does. For what i read now Osmocom have 2 software BTS (Osmo-BTS and Soft-BTS), communicating with the A-BIS over IP interface to OpenBSC: http://lists.gnumonks.org/pipermail/openbsc/2011-March/002529.html http://lists.gnumonks.org/pipermail/openbsc/2010-April/001508.html I've read that only a lot of time ago (2009) there was a discussion about OpenBTS to OpenBSC integration: http://lists.gnumonks.org/pipermail/openbsc/2009-October/000955.html At the current stage of development (2011), with Osmocom finally getting a Software-BTS part communicating to the Software-BSC side, how really complex it would be to integrate the GSM-um related part of OpenBTS into the project? With that approach the 'GSM-um' interface would be a very simplified module of the overall system and osmocom would completely replace OpenBTS all-in-one project. Am i right? -naif p.s. Sorry for the cross-posting, i just wanted to explain the idea and get the communities feedbacks to understand 'at which point' we are in order to think 'what would be required to be done' to achieve that goal.

Problem with osmocon (beginner)
by screaming-pain＠libero.it 04 Apr '11

04 Apr '11

Hi all, I have been trying to load "hello world" for hours with no joy so far :( I am using Ubuntu Karmic and a motorola c115 my with a usb to serial and mot T191 cable. I tried different -m options, most of the times nothing happens, though if I play a bit with the earphone jack and the c115 start button it seems some sort of communication starts and the each time I press the start button I can read the following got 1 bytes from modem, data looks like: 00 . got 1 bytes from modem, data looks like: f1 . got 1 bytes from modem, data looks like: 06 . got 1 bytes from modem, data looks like: 72 r got 1 bytes from modem, data looks like: 82 . got 1 bytes from modem, data looks like: bf . got 1 bytes from modem, data looks like: 7d } got 1 bytes from modem, data looks like: fd . got 1 bytes from modem, data looks like: 7f . got 1 bytes from modem, data looks like: 00 . got 1 bytes from modem, data looks like: a6 . got 1 bytes from modem, data looks like: 51 Q got 1 bytes from modem, data looks like: d2 . got 1 bytes from modem, data looks like: 51 Q got 1 bytes from modem, data looks like: 0a . got 1 bytes from modem, data looks like: 3a : got 1 bytes from modem, data looks like: 02 . got 1 bytes from modem, data looks like: 4d M got 1 bytes from modem, data looks like: a3 . got 1 bytes from modem, data looks like: 14 . got 1 bytes from modem, data looks like: 1b . got 1 bytes from modem, data looks like: 00 . got 1 bytes from modem, data looks like: 00 . what is going on? can anyone help me to understand how to proceed? I got once during my trials the message: Received PROMPT1 from phone, responding with CMD but I had a wrong file name so it just wrote it could not find the file :( I know I am a disaster but I would appreciate if someone could give a hint Thanks you very much, Loretta

R: another compiling problem (beginner)
by screaming-pain＠libero.it 04 Apr '11

04 Apr '11

Hi all, I found out the -nodefaultlibs option is due to a recent patch, so it seems it is solving someone's problem, but it may not be good for everyone. I could compile osmocon-bb without -nodefaultlibs and I found out it compiles without -nostartfiles as well. May be this two options should not be hardcoded, because someone else could have my same problem with the -nodefaultlibs (the -nodefaultfiles did not cause problems to me but seems not to be essential) Regards, Loretta >----Messaggio originale---- >Da: screaming-pain(a)libero.it >Data: 1-apr-2011 13.14 >A: <baseband-devel(a)lists.osmocom.org> >Ogg: another compiling problem (beginner) > >Hi all, > >Sorry for bothering with another compiling problem. >I had the following error while compiling osmocom-bb: > >configure:3246: arm-elf-gcc -Os -ffunction-sections -I/home/loretta/osmocom- >bb/src/target/firmware/include -nostartfiles -nodefaultlibs conftest.c >&5 >conftest.c: In function `main': >conftest.c:15: warning: initialization makes pointer from integer without a >cast >/home/loretta/install/gnuarm-3.4.3/bin/../lib/gcc/arm-elf/3.4.3/../../../.. >/arm-elf/bin/ld: warning: cannot find entry symbol _start; defaulting to >00008000 >/tmp/ccgIuxoW.o(.text.main+0x14): In function `main': >: undefined reference to `fopen' >/tmp/ccgIuxoW.o(.text.main+0x1c): In function `main': >: undefined reference to `ferror' >/tmp/ccgIuxoW.o(.text.main+0x30): In function `main': >: undefined reference to `fclose' >collect2: ld returned 1 exit status >configure:3250: $? = 1 >configure:3287: result: >configure: failed program was: >| /* confdefs.h */ >| #define PACKAGE_NAME "libosmocore" >| #define PACKAGE_TARNAME "libosmocore" >| #define PACKAGE_VERSION "UNKNOWN" >| #define PACKAGE_STRING "libosmocore UNKNOWN" >| #define PACKAGE_BUGREPORT "openbsc-devel(a)lists.openbsc.org" >| #define PACKAGE_URL "" >| #define PACKAGE "libosmocore" >| #define VERSION "UNKNOWN" >| /* end confdefs.h. */ >| #include <stdio.h> >| int >| main () >| { >| FILE *f = fopen ("conftest.out", "w"); >| return ferror (f) || fclose (f) != 0; >| >| ; >| return 0; >| } > > >after hours of trying to understand how to fix this, I figured out that >without the option -nodefaultlibs everything run smoothly. >Now, the problem is that I do not understand much of what is going on and I >wonder, do I need that option and hence should look for a different way of >fixing the problem? > >Thanks for your help, >Loretta > >

NCC alocation
by eisencah eisenach 04 Apr '11

04 Apr '11

I'm having this question about NCC allocation. Is this unique for an operator inside a country? And how it goes if you travel abroad ? (Will the phone look for a network with the same NCC at the begining?) After that it will look at sysinfo and the other stuff but I was wondering how it goes at power up? Thanks.
