gsm850 and host/layer23/src/mobile
by Joshua Lackey 03 Jun '11

03 Jun '11

I'm having issues getting the mobile application to work and I'm wondering if this is a gsm850 problem. I have a couple of debugging ideas but I thought I would post here just in case the answer is obvious to someone else. I'm testing on both a c118 and a c139. I'm using the remotes/origin/sylvain/testing branch and this does have quadband support. I've edited target/firmware/Makefile and defined CONFIG_TX_ENABLE. I have a valid SIM in my phone that works with both phones using the default Motorola firmware. The 'sim reader 1' command is able to gather (most of) the necessary information. (The access class is not correctly read from the SIM but I haven't bothered tracking down why yet -- I just hardcoded an access class of 0xffff.) The mobile program correctly scans the frequency ranges and finds a good tower and then attempts to do a location update. It generates a RACH channel request and then (appears to) send it. The problem is that the phone never receives an immediate assignment response. The log shows multiple immediate assignments received, but none match the request reference (RA and FN the burst was sent in.) So it appears that the tower never receives the channel request I send. The only test I have done so far is to monitor the uplink frequency with a USRP (uhd_fft.py) during the location update procedure. It looks like the phone is actually transmitting at the correct times, but I am not positive. (I'd have to write some custom code before I can definitively say one way or the other.) The only other idea I have right now is that perhaps the timing advance calculation is incorrect. There are a couple of constants used without any explanation and I guess it is possible that these constants don't work for my configuration. I'm going to start going through these constants to determine if I can find a value that works. Any other ideas to try here? Anyone else gotten this to work in the US?

First OsmocomBB Connection Tests (Unsuccessful)
by Drasko DRASKOVIC 01 Jun '11

01 Jun '11

Hi all, I am trying to have some OsmocomBB communication and my procedure is following : 1) I start osmocon with layer1 sw : ./osmocon -p /dev/ttyUSB1 -m c123xor ../../target/firmware/board/compal_e88/layer1.compalram.bin It now waits for power on button from the phone 2) In the other terminal I start mobile application : ./mobile -i 127.0.0.1 Copyright (C) 2008-2010 ...

I guess that MS is doing various cell power measurements and trying to discass with near-by cells over controle channels.

29 May '11

Hi guys I just run into a problem and was wondering whether anybody has experienced the same: When I start mobile with GSMTAB support (./mobile -i localhost) it crashes immediately after the first GSMTAB packet was sent. Any ideas or remedies? I compiled the current master branch and am using Ubuntu 11.04 Ben

Nokia 3310 tracing
by Duncan Salerno 28 May '11

28 May '11

Hi, I've put together a small program that puts Nokia 3310 phones into debug mode (via serial/USB cable) and forwards all sent/received GSM messages and SIM APDUs via GSMTAP to be viewed realtime in Wireshark. This allows you to see the message flows for a real phone on a real network. Nokia 3310's are very cheap and easy to come by, so should appeal to a wide audience. Thought osmocom might be a good home for this utility - could it go into git, and a short page on bb.osmocom.org? Duncan

hmm, sorry, data cable question
by labad jala 27 May '11

27 May '11

Hello techies! I am new to the list and I acquired a c139. I'd like to buy a rs232/jack 2,5mm named t191 flash (and not unlock) cable. They look 100% the same (even stickers). Is this important? I understand that I have also to use a rs232/usb adapter. The one I have (U232P9 with link/tx/rx leds) gives +/-9,4 v. So my concern is to not fry the Moto..Any advise welcome. Cheers.
