Hello. I have some motorola phones that they are no longer required by my friends. These phones are with the filter rework done. The phones are complete with serial and antenna cables but can be sent without them. If anyone is interested, please send me a msg at irc (OsmoCarpenteR), do not reply to this msg. Thanks.

Hi,List I use a TCH/AFS decoder written by Sylvain Munaut and mad to decode the TCH AMR, but it seems there are some bug, but I am not familiar with the convolution codes， the code is following, who are familiar can help me? very thanks! /* * conv_amr.c * * Convolutional code tables for TCH/AFS channels * * Copyright (C) 2011 Sylvain Munaut <tnt(a)246tNt.com> */ #include <stdint.h> #include <osmocom/core/conv.h> /* TCH/AFS12.2 */ /* ----------- */ //# AFS12.2 1/2, K=5, RSC static const uint8_t conv_afs12_2_next_output[][2] = {{0, 3}, {1, 2}, {0, 3}, {1, 2}, {0, 3}, {1, 2}, {0, 3}, {1, 2}, {0, 3}, {1, 2}, {0, 3}, {1, 2}, {0, 3}, {1, 2}, {0, 3}, {1, 2},};

Poll: Osmocom meeting 25th of July?
by Harald Welte 23 Jul '12

23 Jul '12

Hi all! On Wednesday, 25th of July we would have the next Osmocom meeting berlin. However, neither Holger nor I will be in Berlin on that day to host the event. I also know that Tobias will not be in Berlin. Nonetheless, if there are other people that want to meet up, there is no reason to not hold it! So I would like to get some feedback on who would want to attend next wednesday. If there are a couple of people, I'll try to find somebody who can open the CCCB for you.

Tooling up for osmocom, gnuradio, and android ... suggestions ?
by John Case 21 Jul '12

21 Jul '12

I am a mac and NetBSD user and have not run any linux systems for many years. I have never used Debian/Ubuntu/etc. Now I would like to begin doing work with osmocom, GNU radio, SDRs and some android development. I knw it's a religious question, but since I am starting with a completely blank slate, what would be the simplest, most painless distro to set up a development and build environment (cross compiling for arm, building osmocom, gnu radio, and running android development tools and SDKs) ? I assume the answer must be either Debian or Ubuntu, but really have no idea ... comments ? I think the nicest thing would be a distro that *already* had a full complement of the GNU devel/conf/build tools that all the examples in the wiki rely on ... so I wouldn;t have to worry about getting that environment up from scratch ... Thanks.

Receiving on TS=1 ?
by Sylvain Munaut 21 Jul '12

21 Jul '12

Hi, I've hacked something together to quickly test non-combined CCCH. However, I've hit a problem when trying to receive anything on another timeslot than 0. The TX side seems to work fine as the BTS can see my location update request and answers with a reject, but on the MS side, I never see the reject and wireshark only shows invalid incohrent data on the RX. The frames for SDCCH/8 show really nothing valid (looks like random bytes), things like 09 80 7f 47 49 06 1d 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 09 00 47 d5 2d 06 1e 00 00 69 7c a0 91 3d 22 ff ab fe 6c 4f 56 4f 36 ... while the frames for the associated SAACH show at least something gsm-like : 03 03 01 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b but that's not quite a SI5/6 ... To RX/TX on TS=1, I just delayed the RX/TX window by 625 bits (4 * 156.25) when I'm in dedicated channel mode by chaning the 'start' in l1s_tx_win_ctrl / l1s_rx_win_ctrl Is there something else that should be done ? Cheers, Sylvain

Is OsmocomBB save for use in Live Networks?
by Martin Haug 19 Jul '12

19 Jul '12

Hello, I am using a mobile phone with OsmocomBB on it, but with transmission disabled, because I dont have a private GSM-Network. Do you think it is save to turn tramission on or is Osmocom not reliable enough? greetz Martin Haug _________________________________________________________________ Free-Mail Postfach (bis zu 10 GB E-Mail-Speicher) SMS, MMS, Fax und vieles mehr - http://www.smart-mail.de

milenage usage
by ☎ 19 Jul '12

19 Jul '12

Hello. I've noticed that unlike a5.h and comp128.h (include/osmocom/gsm), milenage.h is located in "src/gsm/milenage/" and thus is not included into .deb packages. What are the reasons for that and how milenage should be used properly? -- best regards, Max, http://fairwaves.ru

OsmocomBB Wiki update/upgrade
by George Carpenter 17 Jul '12

17 Jul '12

Hello. This is my first message to the mailing list and I would like to introduce myself. My name is George Tsnikosmaoglou (OsmoCarpenteR) and I live in Greece. I am watching this project for some years now, but due to heavy work load, unfortunately I cannot dedicate a lot of time to contribute to this project. I must give my congratulations to the people that have dedicated their time and show their passion and intelligence through this project. Even though I am watching this project for a lot of time, I consider myself a newbie, but I want to actively participate to the project and contribute to this effort as much as I can. I am already trying to inform as many people as possible, but as you know, you need a lot of effort to explain and convince one person at a time to devote some time to this project. I have met a lot of people that have either technical, or theoretical or both knowledge about GSM and general electronics. These people come with a high educational background, but due to the current working environment, they do not have time to spare to a free Software Open Source GSM Baseband software implementation as OsmocomBB is. The bottom line is that they are interested, but they stop after a while because the first steps are always difficult. So here are my proposals. It would be nice to have a complete and easy to read wiki. I know that this project is created and maintained by people who have devoted a lot of time to this project, but the current status of wiki does not allow a newbie to gather all the information that are needed to start easy and get in the project as fast as possible. I remember my first attempts to load the firmware to the mobile phone and I remember this was somewhat difficult. Thanks to some help from the IRC people that hang out and some manuals that float on the net (see srlabs gsmmap and gprs sniffing tutorial), I managed to get started. And never underestimate the frustration and the temper when you keep trying and trying to load your first firmware, or the excitement and awe when you see these sweet words (OsmocomBB) on the screen of the mobile phone. Personally, when I finally managed to load and run my first application (ccch_scan), something was created in my mind that this project really stands for something innovative and genius. But for most of my friends, this did not happen. Many of them stopped because they found this whole procedure frustrating and nerve breaking, so they either stopped or they left this aside. Also I see that although I am trying to devote sometime, there are always some expected problems. These problems are usually solved if you read the mailing list or ask help from IRC, but in many cases this takes a lot of effort and after some hours and painkillers, you cannot figure out how to solve a problem. Just to mention the latest FULL LRAM compile problem that exists since the start of the year. Yesterday I was trying all day to find a solution, but there were a lot of candidate solutions and patches, but none was solving the actual problem. This would have saved me a lot of time if this was mentioned in the wiki and if someone had devoted some time to print 2 lines of comment or directions on how to solve or explain to many people that it is not solved. Because I see that no one from the persons that have real skills and knowledge of this project spares some time to update and evolve the OsmocomBB wiki, I propose to create some “booty”, so we get a proper wiki for this project and the person or persons that will create this will be “rewarded” for their time and effort. I know that knowledge has no price, but I propose to create a “booty” bank with either money or/and services or/and equipment. Anything that any individual can contribute. I think this will boost the quality of this project and will be something interesting for some newbie to get involved. Some things that I found that this project needs is a newbie/getting started wiki. Detailed and with information and explanation as you were talking to a 5 year old child. This should include detailed information on what equipment and first things to do before you even start your first attempt to load any code to the phone and then how to load the first firmware and load the first application. I really liked the srlabs instructions about gprs and gsmmap. It was a good way to start and it was a step by step manual and easy to understand. A full list of existing applications. This will include detailed explanation of each application and it’s capabilities. Also how to load them, all the application parameters and what you can do with them. A hints/tips list. This will be some useful information about the OsmocomBB project. What to do and not to do. For example if the loader shows always the FMTOOL message and what o do in similar situations. To take extra caution to the physical contact of the cable, etc. Issues that are encountered and are standard to the project. A current issues/proposed solutions to current problems. I cannot find a more proper example as the current FULL LRAM compile problem that we currently have. There can be a small description of the problem and candidate solutions till the problem is fully solved. This will spare a lot of time to persons that encounter problems and save a lot of traffic in the IRC and mailing list. It will also be a database of knowledge for genius solutions or efforts to solve an issue. A todo list. This refers to the masters of this project. That is because they usually show the direction of the project. They who have deep knowledge of this project can show where this project is heading for. So a todo list to get there will be nice. You never know, even a newbie may solve an issue that is it totally new to the project, just to evolve the whole project. Right now I do not find any reference or it is very difficult to know (even the masters of OsmocomBB) where this project is heading to. A full GSM documentation. This will include detailed documents and references on each and every aspect of GSM technology. I am talking for an encyclopedia of everything that is referred in GSM technology. I think this is very important to have all the information that is needed all in one place and updated on any occasion. This is very important for someone who really want to get involved in the project. This can also include 3G and future communication technologies. I am talking for the bible of communications. Of course one step at a time. I know that all the information that we need is out there on the net, but all the information gathered in one place and shorted by an expert would be the ultimate tool. Of course everything that I mentioned does not have any meaning or purpose if the wiki is not updated frequently. Sorry for the big message. Thank you.
