Hey there, I bumped into this error when testing gprsdecode from srldabs.de When I try the sample .dat files provided from srlabs.de it works fine though. Any hints?
Kind Regards

Hey, I finally watched Nico's talk "let me answer that for you" and heard him say he ported layer2/3 to target.
Also found a mailing list message about him cleaning it up and putting it up on git and sending it to a few folks.
Did that code ever get shared? Would be cool to play around with and is certainly something I would eventually want to accomplish for my project of making a phone that works by itself.

Dear all, I vae the C115 with a T1 USB to Serial cable with the Prolific
chipset.
When i run osmocon i get :- an its just sits there with no further
processing.

I think the cable is ok as when i run my fingers on the tip i get random
Zeros so it appears to be talking to the cable.
Also when i tried to run Mobile i get the :- even though i created the
Mobile.cfg file in /etc/osmoco
Failed to parse the config file: '/home/raz/.osmocom/bb/mobile.cfg'
Please check or create config file using: 'touch
/home/raz/.osmocom/bb/mobile.cfg'
I have spent some hours researching the lists and trying various things to
no avail but I want to continue until I resolve this issues and use this
great stack to learn about the GSM network.
Please advise.
Great full for any help or pointers but this maybe a timing issue that is
difficult to debug.
Thanks

hi,
i did a lot of resarch and testing on cell selection and re-selection
process the last two week.
the cell selection process, network selection process (manual and
automatic) and mobility management process were already implemented in
OsmocomBB a long time, but turned out to be buggy and incomplete. i made
test drives to check the process and debugged it.
the re-selection process is new. it is used to track surrounding cells
while listening to the BCCH of the current cell (camping on a cell).
special extension to the layer1 firmare is used to measure neighbour
cells. if an neighbour cell becomes 'better', the mobile switches to
that cell, depening on different criteria. now it is possible to move
with OsmocomBB.
the re-selection process is not handover! handover is a process where a
phone switches between cells while doing a call. handover is one next
step to implement. the process is a little more complex, because it
requires not only neighbour cell measurements, but also syncing to them
without interrupting the traffic channel. most layer 3 stuff of handover
is already implemented.
if you like to play and test your moving OsmocomBB, you can check out
the "jolly/roaming" branch. it contains the extension to layer1, as well
as sim reader and fixes from "sylvain/testing" branch. use both "mobile"
and "layer1" firmware from this branch.
in order to see some process at VTY, you can do:
enable
monitor network 1 (continously display the strongest cell and neighbour
cells)
show ms 1 (to see current states)
show neighbour-cells 1 (to see a more detailed current list of
neighbours)

Hi,
in the osmocom bb mobile.cfg I don't see any posibility to set a fixed
Kc encryption key and the tmsi.
How could I achieve that osmocom uses my defined Kc and tmsi?
cheers,
Simian

Hi,
I'm trying to run the latest osmocom-bb git on a Motorola C118 phone.
After a minor problem with the build (as you may've noticed in the
patch I've sent). I got to the point of successfuly running layer1 on
the phone and the mobile app on the PC (I have also enabled TX). The
process seems to be stuck on trying to perform a location update. The
status of the ms is always either:
show ms
MS '1' is up, MM connection active
IMEI: 000000000000000
IMEISV: 0000000000000000
IMEI generation: fixed
automatic network selection state: A1 trying RPLMN
MCC=104 MNC=002 (104, 002)
cell selection state: connected mode 1

(104, 002)
radio ressource layer state: connection pending
mobility management layer state: wait for RR connection (location updating)
OsmocomBB>
or
show ms
MS '1' is up, service is limited (pending)
IMEI: 000000000000000
IMEISV: 0000000000000000

(104, 002)
radio ressource layer state: idle
mobility management layer state: MM idle, attempting to update
OsmocomBB>
I think, that because of this I can't make any calls or send sms (all
the requests are being rejected):
OsmocomBB# call 1 <X>
call 1 <X>
OsmocomBB#
% (MS 1)
% Call has been rejected

Can you provide me any hints on how to debug this ? Why is the

Thanks in advance for your help.

Hi All
Just wanted to confirm that I got Osmocom-BB up and running on a Raspberry Pi.
I did not use the GPIO UART pins but USB <-> serial converters.
I tried Motorola C118 and C155 with success.
Everything you need is already described:
http://bb.osmocom.org/trac/wiki/GnuArmToolchainhttp://bb.osmocom.org/trac/wiki/libosmocorehttp://bb.osmocom.org/trac/wiki/Software/GettingStarted?redirectedfrom=Gett…
My previous problem seems to have been a not fully compatible crosscompiled toolchain. (it worked mostly, but I could not log-in to a cell and the spectrum view crashed on the RSSI Firmware.
Also if you want transmit capability (or flashing) then you need to activate those features in the makefile.
Thanks Sylvain (confirming c118 will work) and all others who are involved!!
PS: Any news on the "emulated BTS" that has been presented at last years chaos communication congress?
I have 2 C118s + 1 normal USB serial dongle + 1 capable of burst ind.
I hope this will suffice to also run also a possible future 1 trasmit phone + 1 receive phone configuration.
I assume that even without the filter change it should be enough to send a few meters of distance.
