Hi all,
After buying a super Sim Kit (16 in 1) from China, I tried the reader (green PCB inside a blue transparent plastic case with a blue LED) and SIM (identified as a fakesupersim) with pysim tool. However i am getting the following error:
/pySim-prog.py -n 26C3 -c 49 -x 262 -y 42 -z 1234 -j 1 -t auto
Insert card now (or CTRL-C to cancel)

I checked mailing lists and haven’t found anybody who had similar problem with pysim. Also I have tried forcing different models of SIM, but nothing is working. Obviously I can remove this check from the script file (__init__.py in /pySim/transport), however somebody had a reason to put such condition there. I would like to ask if it is safe to remove that line of code and the purpose of that line of code.
Thanks a lot and best regards

Dear osmocom developpers,
This is just to let you know that the Python library pycrate has a new home
: https://github.com/pycrate-org/pycrate. The packages on Pypi are now
feeded from there. This library can be used in many cases dealing with
mobile signalling.
I wanted to let you know, as even if I am not aware of any osmocom projects
depending on it, some of you may use the library from time to time, or
could have local applications depending on it.
Best Regards
Benoit

I means: is the interaction with mtp3 layer implemented (is sending sccp
data by mtp3 implemented by the library?)?
Also, what about the reception of data from mtp3 layer. is that implemented
in the sccp lib.
I am asking these questions because I see the code of mtp3 in the lib but no
significant call is present in the sccp part of the lib.
Thank you for your help.
Hello Osmocom community,
Over the past several months I developed my own RTP endpoint
implementation library (alternative to libortp), and I seek to get it
merged into libosmo-netif so it can be used by OsmoBTS as an option:
https://gerrit.osmocom.org/c/libosmo-netif/+/39280https://gerrit.osmocom.org/c/libosmo-netif/+/39281https://gerrit.osmocom.org/c/libosmo-netif/+/39291
I am now working on documentation, which I need to finish before I can
lift these patches out of WIP in Gerrit. The last of the 3 WIP patches
linked above is the one adding an adoc manual, built with the same
tools as other Osmocom manuals, and I need some help with this one:
1) When I run './configure --enable-manuals' followed by 'make' on the
Debian machine which Vadim provided to me for Osmocom documentation
work, everything seems successful and I get a PDF rendering of my WIP
manual. However, as soon as I uploaded this patch to Gerrit, I see a
build failure in Jenkins. What am I doing wrong? I'm afraid that my
knowledge of Autotools is not good enough to figure this one out.
2) My progress in writing the actual manual has reached the point
where I need to insert some graphical diagrams showing the flow of RTP
packets and the latency and jitter they experience in transit. I am
thinking of one horizontal axis showing regularly spaced packets as
they are emitted by the source, then forward-and-down arrows showing
their transit with fixed or variable latency, then another horizontal
axis below showing the receiver's view of time, with marked arrival
times of packets (endpoints of latency arrows) and fixed-spacing times
when the GSM or TDM system polls the jitter buffer.
Question: what is the appropriate tool within the accepted Osmocom
adoc suite for drawing such diagrams? If I weren't trying to get my
RTP implementation accepted into Osmocom, I would have written this
manual in troff on my favorite 1980s UNIX system, using pic preprocessor
in the troff suite for graphical drawings like this one - but I reason
that I need to write my manual within Osmocom documentation framework
in order to maximize the chance of the associated code library being
accepted into libosmo-netif, with follow-on patches to osmo-bts to use
it optionally as an alternative to libortp.
3) When I do successful test builds on Vadim's Debian machine and get
a PDF rendering of my WIP manual, the cover page in the PDF features
both Sysmocom and Osmocom logos just like the mainstream Osmocom
manuals, with Sysmocom logo on top. While this arrangement is probably
appropriate for the existing manuals which were written predominantly
by members of Sysmocom crew, it seems quite wrong for an external
contributor's manual that does not contain a single sentence written
by Sysmocom. How do I tweak things to remove that Sysmocom logo from
the cover page, or even better, put San Diego 2G Association logo in
its place? My contributions to Osmocom are directly linked to my
efforts to build a new GSM network in San Diego, hence there is some
symmetry between Sysmocom and SD2G in terms of Osmocom FLOSS project
contributions, except for the rather big asymmetry in that SD2G is
strictly non-profit.

Hi all,
Just wanted to share an issue and a quick workaround I found for it in case
anyone else has the same problem. I believe a cmd2 update is causing
pySim-shell to fail. After installing it on a fresh install of Ubuntu
Server 20.04 and getting the following error when I run "python3
pySim-shell -p0":
>Using PC/SC reader interface
>Autodetected card type: sysmoUSIM-SJS1
>AIDs on card:
> USIM: a0000000871002ffffffff8907090000

allow_cli_args=False, use_ipython=True, auto_load_commands=False,
command_sets=basic_commands, >startup_script=script)
>TypeError: __init__() got an unexpected keyword argument 'use_ipython'
If you run into this you can fix it by uninstalling cmd2 and reinstalling
cmd2 with "pip3 install cmd2==1.5".
Best,
Bryan

A TS can be GSM_PCHAN_TCH_F_PDCH; those are the only ones for which we
send a PDCH ACT message.
We send a PDCH ACT message
- during init (CHANNEL OML's state changed to enabled -> send PDCH ACT),
- and upon channel release ack when pchan == GSM_PCHAN_TCH_F_PDCH.
So the question is, when we receive a channel release ack, could that be
the PDCH release and we switch PDCH right back on by accident? No, because
we only receive a chan rel ack when the *TCH/F* is being released.
That is because the PDCH release is initiated "internally" from the PDCH
DEACT, and thus this condition in common/rsl.c rsl_tx_rf_rel_ack() catches
on, which existed before dyn PDCH:
if (lchan->rel_act_kind != LCHAN_REL_ACT_RSL) {
LOGP(DRSL, LOGL_NOTICE, "%s not sending REL ACK\n",
gsm_lchan_name(lchan));
return 0;
}
In rsl_rx_rf_chan_rel() the rel_act_kind is set to LCHAN_REL_ACT_RSL, but
not in the rsl_rx_dyn_pdch().
This is analogous to the ip.access way -- the ip.access nanobts replies to
a PDCH DEACT with a PDCH DEACT ACK and doesn't send a separate channel
release ack.
Maybe we could set rel_act_kind to some new LCHAN_REL_ACT_IPAC_DYN_PDCH
for clarity? (But we shouldn't actually send a release ack, to stay
compatible.)
Even though it works as-is, we should indeed add another flag check:
- We do check the flags that no ACT/DEACT is already pending;
- And we do send a PDCH DEACT only if ts->flags & TS_F_PDCH_ACTIVE;
- But we would send a PDCH ACT despite ts->flags & TS_F_PDCH_ACTIVE.
This should never happen, but it would make sense to ensure that.

Hi,
I built libosmocore head (commit
84dcf73625513af44e711b2c99e21ee2c33b7eff at that time) on Fedora 43
(rawhide) and on s390x 4 tests failed. Iit's s390x running in qemu on
x86_64, but it also fails on native s390 - there I saw failures of
tests 25 26 69 90 (unfortunately I don't have the log from the native
run). So probably more tests can coredump, to see all the problematic
tests, it would probably require running through the valgrind. I am
reporting it according to the provided instructions
thanks & regards

Hi Experts,
I want to integrate EPC core (Open5GS) with open-source SGSN, It would be very helpful if anyone can share any document where I can find the installation steps and all.
Thanks in advance for your valuable time and consideration.

Sandip Biswas

Hi,
it came up again in gerrit again.
Currently the osmocom style states doxygen style comments should be done in the .c file.
Doxygen are those comments:
/*! a brief description of the function
* \param something Some description of the use
* \return 0 if ...
*/
Doxygen takes those comments and generates a html documentation of the code.
I would like to change it to have those in the headers files instead (when the function in included in a header file).
When using the doxygen comments only for doyxen, for sure, there isn't a difference between
having it in .c or in .h files.
But when using IDEs or language servers, they usually only parses headers files and
the .c files of the current active project (e.g. osmo-sgsn),
but not the .c files of other projects (libosmocore).
On the downside I only see the problem of increasing the size of header files, but I don't see
an issue in here.
Any thoughts?
Best,
lynxis
