about voice
by shrek wu 23 May '11

23 May '11

hi all, About voice，I have one question. In the latest git code, when I use bb to call other phone, it will product a file voice.raw. How I can play the voice.raw? which kind of format? 16bit or 8 bit pcm?16khz and 8khz?LSE or MSE? In fact i used the cooledit to play it, both 16khz and 8khz, it has only noise. Other question, I want to input voice from pc that run BB, then the voice can be sent by C123. But I found the voice that be sent by C123 is C123 input voice. Can we realize the idea? Best Regards Shrek W

buzzer driver
by José Luis Pereira 24 Apr '11

24 Apr '11

Hi all, my name is Jose Pereira, and i'm very interested in helping you with some code! I've wrote the buzzer driver for calypso, not so sure if will help you of anything, but was just for experimenting :) Anyway, i send the patch in attachement. The interface can be simply #include <calypso/buzzer.h> buzzer_mode_pwt(1); buzzer_volume(40); buzzer_note(NOTE(NOTE_E,OCTAVE_5)); Please let me know what do you think of the code, and in what way i can further help. Best regards, -- José Pereira http://onaips.blogspot.com

How to build osmocon for the target?
by Dave Schmidt 29 Mar '11

29 Mar '11

Hello everyone! I'm trying to run osmocombb on Neo Freerunner. Read and hopefully understood http://bb.osmocom.org/trac/wiki/{CalypsoRomloader,osmocon,OpenMoko}. One thing I completely miss is how to build osmocon for the target phone to be able to run ./osmocon -i 13 -m romload -p /dev/ttySAC0 layer1.highram.bin In the source tree, osmocon is built only for the host, and I do not see any configuration options to enable it also for the phone... Thanks in advance, D.

Funding from CELF to work on Osmocom integration
by Pierre Pronchery 29 Mar '11

29 Mar '11

Hi baseband-developers, I am looking for a freelance developer, preferably (provably) knowledgeable about the Osmocom project, to work together on a project potentially funded by CELF; the objective is to use Osmocom through a telephony GUI to make regular phone calls. I would like to use the "Phone" project from DeforaOS as the GUI, but feel free to mention if you are from a different project and want to step in. Some background information: CELF is otherwise known as the CE Linux Forum. It's supposed to merge with the Linux foundation eventually: http://www.linuxfoundation.org/news-media/announcements/2010/10/linux-found… What brings me here is their "CELF Open Project Proposal 2011": http://elinux.org/CELF_Open_Project_Proposal_2011 « The CELF Open Project Proposal is a process whereby members of the public can submit to the CE Linux Forum ideas and proposals for projects that they think should be worked on to enhance embedded Linux » FWIW, it was mentioned in the Openmoko Community Updates for February 2011: http://wiki.openmoko.org/wiki/Community_Updates/2011-02-01#General_News This is how I got to know about it right before the deadline, and had to rush to submit my current project idea, which is to integrate Osmocom with a Linux-based telephony GUI: http://elinux.org/Add_Osmocore_support_to_the_DeforaOS_Phone_GSM_stack About Osmocom: http://bb.osmocom.org/trac/ « OsmocomBB is an Free Software / Open Source GSM Baseband software implementation » The submission was accepted, and I am now required to send a bid for the project. Needs to be estimated: - how much time would be needed (and availabilities), - how much money would be needed, - which issues can be anticipated. I will also welcome suggestions as to which hardware to use for this task. Technically, the proposal is about integrating Osmocom with a Linux-based smartphone environment, so I'm not speaking about improving the LCD support for feature phones. Something like the Openmoko Freerunner is closer to what I have in mind, which is also what I'm currently using (and as you may know, it has a Calypso-based GSM baseband, which is supported by Osmocom already). Before I conclude, let me mention that I want definite answers about people who will be serious about this. Feel free to forward this message to anyone else whom you know and should also participate to this project. My current estimation is that three to four weeks should be sufficient for two people to: - expose and glue a more "UI-developer-friendly" API, probably closer to the Telnet interface (see layer23/src/mobile/vty_interface.c) - make sure everything is as reliable as possible (eg baseband initialization...) - likewise, make sure the GUI and Osmocom are integrated correctly - test, test, test. HTH, -- khorben

Does the jolly/bts tree work?
by cbalke＠charter.net 28 Mar '11

28 Mar '11

I got two phones working with osmocom-bb. I compiled jolly/bts and it runs with two phones. I also compiled openbsc and connected the bts application to it. The problem is that timer T200 expires. I also get TX TCH/F errors before the timer expires on the bts application side. I am not sure if this is because of a configuration error on my part, or if the code was never completed enough to link a phone to it. I have tried using the default nanobts configuration file, but it does not work. If it isn't completed yet, what needs to be done? Is there anything that needs to be changed in the default nanobts configuration file? Just so you know, The reason why my email display name is not here, is because I am using backtrack linux and webmail to post this. Thank you for taking the time to help me, Calvin E. Balke

[ADM] New commitlog mailing list
by Harald Welte 26 Mar '11

26 Mar '11

Hi all! We haven't had a functioning commit log mailinglist since mid-2009, when the revision control system of openbsc was converted from svn to git. Especially today, with the large number of separate git repositories on http://cgit.osmocom.org/, it is very easy to loose track of what other developers are doing. The new mailing list 'osmocom-commitlog' (renamed from openbsc-commits) will receive updates from all repositories on git.osmocom.org. Feel free to subscribe at http://lists.osmocom.org/mailman/listinfo/osmocom-commitlog Cheers, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

[ADM] Problems with osmocom git server
by Harald Welte 26 Mar '11

26 Mar '11

Hi all! We're sorry to report that there are some problems with our git repositories at the moment, resulting in 'early EOF / index-pack failed' messages when users are attempting to clone one of our repositories. The problem has been thoroughly analyzed, but even after many hours of analysis, no solution has been found yet. Your best chance is to keep re-trying the clone, in 5-10% of the cases it will succeed. More technical details are available at this posting to the git mailing list: http://article.gmane.org/gmane.comp.version-control.git/169909 Sorry for the inconvenience. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
