Calypso_BTS stopping after few minutes
by robert 19 May '16

19 May '16

Hi, While experimenting with the calypsoBTS using a Motorola C118, I noticed that the transceiver always stops after a few minutes and displays the following messages: <0011> trx.c:419 TRX Control recv: |POWEROFF| <0011> trx.c:220 TRX Control send: |RSP POWEROFF 0| Does anyone know what is causing this problem? Best regards, Robert,

disable force rekey
by frank.holtz＠tutanota.com 13 May '16

13 May '16

Hello, I am facing an issue with the mobile app inside osmocom-bb. I checked with gr-gsm that my telecom operator changes the Kc ( by sending auth request) every 5 events (call or sms). But with the same sim card, I can see on Wireshark connected to the mobile app, the osmocom-bb phone received an auth request before every event. So my guess something causes the BTS to send a new auth request but only with osmocom-bb mobile app. I checked the source code, i found the option "force-rekey". Even with this option in mobile.cfg disabled I got the same issue. I saw that when enabled this option set the key sequence to 7. I tried with the latest version of osmocombb/libosmocore. Even with previous version from 2012 and last 2011 both osmocom-bb/libosmocore, different computer/ different phone (C123, c118 and c139), different cables (I use a shielded FTDI and a CP2102). Has anybody faced the same situation ? Have you an idea from where it can come from ? Thank you for your help Frank

Help with a bricked C118
by Simone Margaritelli 22 Apr '16

22 Apr '16

Hi everyone, I just got today a Motorola C118 with a CP2102 interface, so I’ve cloned and compiled the osmocom-bb and started playing with it, everything looked great ( osmocon working, hello world app, rssi and so forth, everything 100% perfect ). Then I started following this page http://osmocom.org/projects/baseband/wiki/Flashing_new <http://osmocom.org/projects/baseband/wiki/Flashing_new> Until I reached the point where the menu.e88loader.bin file was referenced … I don’t have this file (I’m on the master branch), so I closed every tabs of the terminal to search which branch contained that file. Problem is, I’ve executed all the commands prior to this one: host/osmocon/osmoload fprogram 0 0x012000 target/firmware/board/compal_e88/menu.e88loader.bin ( also saved the original loader ) and now the phone doesn’t turn on anymore, neither osmocon is able to detect it … so I guess it’s bricked? is there any way to unbrick it? Thanks for your help.

OsmoDevCon 2016 update
by Harald Welte 07 Apr '16

07 Apr '16

Dear attendees of OsmoDevCon 2016, below are some updates regarding OsmoDevCon 2016 = Lunch Catering = OsmoDevCon lunch catering has been finalized by now. I wanted to try some change by having (authentic) thai food, but unfortunately that didn't work out and we're back to our trusted old suppliers for all of the lunches. More details are available on http://projects.osmocom.org/projects/openbsc/wiki/OsmoDevCon2016 = Dinner Catering = In terms of dinner catering, we didn't plan/schedule anything yet. I know it was a request to have it and we introduced it (last year?) but I didn't have time to actively look for a sponsor for this in 2016, sorry. If you think it's important, I can try to get something organized for dinner too, but there's not much time left. It might be easier to simply go out in 2-3 groups, order pizza from the place down the road or even place a larger 'a la carte' order from another place. = Schedule / Talks = Thre's already a list of topics listed at the wiki, specifically: http://projects.osmocom.org/projects/openbsc/wiki/OsmoDevCon2016#TalksDiscu… I think we still have plenty of slots for talks, presentations, discussions, workshops, you name it. Each of you: Please take some time to think about a) topics that you would be able to contribute to the event by giving a talk or leading a discussion or workshop b) topics that you would like to hear about from somebody else Even if we do the actual scheduling ad-hoc at the event itself, it still is useful to have some advance notice about the topics, as the speaker(s) will need to prepare accordingly. = Attendance = If you have registered but will not attend, please let us know as we can still adjust the amount of food we get delivered, and we might offer your seat to somebody else. If you did not register but are an active contributor to the project(s) and would like to attend, let me know, too. I will let you know if somebody cancels their attendance. Looking forward to meeting all of you in Berlin soon.

Can't flash app on C140(E86)
by Alex 31 Mar '16

31 Mar '16

I'm trying to flash the EMI app on a C140 using this tutorial: http://bb.osmocom.org/trac/wiki/flashing_new I can't fine menu.e86loader.bin file so I've flashed the menu.compalram.bin instead. All seem to be fine, but if I press the power button the screen doesn't turn on. I've made this procedure many times, but without success. Instead if I flash it in the ram, it work great. Why?

Re: Time to rename projects.osmocom.org to osmocom.org
by Вадим Яницкий 28 Mar '16

> I added: > proxy_set_header X-Forwarded-Ssl on; I think if nginx is used as main back-end (without Apache), this header means nothing. In this case just refer this guide: https://scotthelme.co.uk/setting-up-hsts-in-nginx/ If I'm not right, and there is also Apache server, follow: http://stackoverflow.com/questions/16042647/whats-the-de-facto-standard-for… С наилучшими пожеланиями, Яницкий Вадим.

Time to rename projects.osmocom.org to osmocom.org
by Holger Freyther 28 Mar '16

28 Mar '16

Hi, I think we all liked tnt's proposal to just call it osmocom.org. Are we ready to make the redmine available as osmocom.org (and redirect www.osmocom.org, projects.osmocom.org to it)? As first step of redirects I propose: http://bb.osmocom.org/ -> http://osmocom.org/projects/baseband http://openbsc.osmocom.org/ -> http://osmocom.org/projects/openbsc http://tetra.osmocom.org/ -> http://osmocom.org/projects/tetra http://simtrace.osmocom.org/ -> http://osmocom.org/projects/simtrace http://security.osmocom.org/ -> http://osmocom.org/projects/security http://gmr.osmocom.org/ -> http://osmocom.org/projects/gmr http://sdr.osmocom.org/ -> http://osmocom.org/projects/sdr any objections or corrections to that? kind regards holger

Hi, Is is possible to record a specific call using osmocombb? I want to record a call being made on the osmocombb phone not to sniff calls over the air. Best regards, Robert,
