Dear all, Time has come to fill out the "Talks/Discussions/Workshop / Hacking" section of the wiki page. If you have something you'd like to present, talk about or hack on, add it there. A simple descriptive title along with an estimated duration is enough. I guess we'll collect those for 2/3 weeks and then start making the schedule. Cheers, Sylvain

BTS using osmocombb trx

by Christian Schulte

Hello dear osmocom team first off, thanks for all the work you have put into this project. Its great to have a starting point for toying with this new/old technology. ;) I got myself a C155 and have used osmocom-bb on it to read some traffic with wireshark. So far everything works nicely. Now i wanted to communicate with a second phone and have tried setting up a BTS following this guide http://openbsc.osmocom.org/trac/wiki/network_from_scratch (using a single phone) My problem is that the phone doesnt transmit anything. Yes i have enabled the transmitter flag in the Makefile. ;) When i use osmocon to load the TRX into the phone and start the osmocom-transceiver i get this debug output from osmocon. ... Synchronize_TDMA =>FB @ FNR 26585 fn_offset=2002505 qbits=4924 LOST 1910! BTS MODE: 255 65535 {0,0,0,0,0,0,0,0} TX 0..7 RX 0..7 After taking a look at the code the values seem weird and they come from the transceiver function l1ctl_tx_bts_mode() like that. /host/layer23/src/transceiver/l1ctl.c:120 As a test i got the phone to transmit something by overwriting the values on the TRX side. I havent gone further yet but wanted to ask if someone could maybe point me to an obvious mistake i did before i spend more hours on this issue. A hint as to how i enable the different logging settings would be great as well. thanks, best regards, Christian

Query regarding running osmoocomBB

by neetesh saxena

Hi everyone, Here, i wish to know the answer of a basic question. When I uploaded the firmware onto the mobile phone (with ./osmocon command), I can start other application programs like CCCh program, mobile program in other terminals. My problem is when I am doing it I can see that the layer1 is uploaded onto the phone but I am not able to switch on my phone. When I again press the red button to start phone, it again starts getting uploaded layer1. When I terminate the command of uploading firmware and start my phone then I am not able to view of SIM details and it shows me "service is unavailable" or "administratively down". My question is we need to continue run the terminal with ./osmocon command (for uploading layer1) or i need to stop it after uploading layer1 once onto the phone. When to switched on my phone ? With regards Neetesh Saxena...

[RFC] [ADMIN] Making lists subscriber-only?

by Harald Welte

Dear all, so far the osmocom.org mailing lists have always been in a 'non-members are manually moderated' mode. This has created a lot of work for manual list moderation, where a lot of the messages caught are simply spam, and only the occasional valid message is being received. I'd like to thank the list moderators for taking care of this. However, in more recent discussions, we were considering to move the lists to a completely closed mode, i.e. postings would automatically be rejected from non-members. The automatic response would contain a description of how to subscribe in 'nomail' mode, i.e. to subscribe in a way to be able to post to the list, while still not receiving any incoming traffic. The latter should be fine for occasional posters who don't want the bulk e-mail that goes with a full/regular subscription. Please provide feedback in case you disagree with that change. Unless there is major opposition, we will likely transition to the 'closed' mode within one month. Thanks, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

[PATCH] adjust msgb api

by ☎

Hi. While looking at osmocom-bb compilation warnings I've noticed that there are plenty of those cause by signed-unsigned comparison with msgb-related functions. Attached is a trivial patch which fixes that by changing int -> uint16_t. For the sake of completeness I've also changed other functions to explicitly use uint16_t - this is used for length fields in "struct msgb" anyway. Although technically it's API change I do not expect any sane code to break. If you still think it's potentially insecure, this could be applied during next api version bump alongside with gprs api change. -- best regards, Max, http://fairwaves.ru
