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.
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:

If you run into this you can fix it by uninstalling cmd2 and reinstalling
cmd2 with "pip3 install cmd2==1.5".

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,
My name is Brackley Cassinga Form DRC, we run a community network called
pamoja net where we offer gsm services using osmocom open source software
and OC Base station.
Recently I have tried to install another base station as the same installed
but I could not find any resource guiding through all the steps to take to
run NIB on a base station.
I'm currently running Ubuntu and I will appreciate if you could guide me on
the installation of BSC,hlr,MSC , in order to run a basic gsm network.
Thank you. Regards

Dear fellow Osmocom developers,
as you all know, we've sadly had to skip OsmoDevCon 2020 and 2021,
trying to compensate it at least to some extent with our OsmoDevCall
every two weeks.
The COVID-19 pandemic is far from over, and we don't know what the
upcoming winter season will bring.
Nevertheless, I think it would be a good idea to start a discussion of
whether we should plan for an OsmoDevCon in 2022.
I personally would say let's plan for the usual late April 2022 time frame,
and if the pandemic situation deteriorates, we can still cancel it with
something like one month lead time.
I would also personally suggest to limit attendance to people who are fully
vaccinated, and in addition do a self-test for all participants every
morning.
In terms of venue, we might also consider to move to a venue that allows better
ventilation. Irrespective of the above we can also bring the air filters from
the sysmocom office.
So with that as an input statement, I would like to hear your opinion
on the above proposals. Who would want to attend? Any complaints against
the "vaccinated only plus daily self-tests in the morning" approach?
Regards,
Harald

"Privacy in residential applications is a desirable marketing option."
(ETSI EN 300 175-7 Ch. A6)
Hello,
I need help to understand my problem installing a simple HelloWorld applet
on USIM card.
There is already a USIM applet (AID: a0000000871002ffXXffXX89) running
there, so perhaps that's the issue.
1. Should I remove it?
Here is my code to INSTALL (for load), LOAD, INSTALL (for install):
https://gist.github.com/Novitoll/2d8146b85f4384eb4dd039eb8116d1ed
2. All of them returns 9000, which is OK, I'm using a simple CardReader,
but when I insert the SIM to a phone, no applet comes up.
Initially, I thought that the AID for instance is the reason. So when I do
https://gist.github.com/Novitoll/2d8146b85f4384eb4dd039eb8116d1ed#file-appl…
... module_aid="d07002CA44900101", app_aid="d07002CA44900101"
I'm getting 6A88 (Referenced data not found). I changed it to
A0000000871002FFffFFff8900000101
A000000087 - RID for 3GPP
1002 - USIM
FFff - country code
FFff - card issuer code
89 - Telecom
00000101 - App version? Havent figured out this yet
the answer is 9000. But no app pops up on the phone once I insert SIM card
back.
3. Also I'm checking if any load file actually ends up by taking some
non-volatile space in SIM -- no difference.
4. After Install for install, there is nothing to be done, rght? Like
updating EF_DIR is not required, where USIM is the only applet.
Could you please assist? My twitter is twitter.com/novitoll

Dear Osmocom community,
It's my pleasure to announce the next OsmoDevCall on
January 28, 2022 at 20:00 CET
at
https://meeting4.franken.de/b/har-xbc-bsx-wvs
In this edition, laforge will present a number of brief (lightning)
talks about a number of projects he's currently been thinking about or
working on, including
* efficient TDMoIP protocol
* TDMoIP community network
* hardware design of ISDN BRI interface for TDMoIP community network
* continuous testing setup for simtrace2 "cardem" firmware
* non-transparent ISA-over-USB bridge attached to qemu
The idea is to ping-pong some ideas wit others and maybe find somebody interested in helping out.
This meeting will have the following schedule:
20:00 meet + greet
20:10 various brief talks (see above)
21:00 unstructured supplementary social event [*]
Attendance is free of charge and open to anyone with an interest
in Osmocom or open source cellular technologies.
More information about OsmoDevCall, including the schedule
for further upcoming events can be found at
https://osmocom.org/projects/osmo-dev-con/wiki/OsmoDevCall
Looking forward to meeting you on Friday.
Best regards,
Harald
[*] this is how we started to call the "unstructured" part of osmocom
developer conferences in the past, basically where anyone can talk about
anything, no formal schedule or structure.

Hello,
Sorry, for the late reply. (replying again in new thread as prev mails failed).
Quoted prev mails in quotes below.
>> Which is "your test sim". Can you share the make and model?
It's a sysmoUSIM-SJS1, I believe.
I'm receiving 9000 for INSTALL for load, and for consequent LOAD
commands 9000 as well. Only for the last INSTALL for install, I'm
getting 6A88 (reference data not found). I think, the issue is in
AIDs. I'm trying to figure out if I should use arbitrary bytes for AID
or construct AID (which includes RID + RIX) the same way as
existing Load Files, Applets' AID are on the SIM card?
I'm using d07002CA44 from this https://github.com/mrlnc/HelloSTK2,
I believe that should be reason for the 6A88 error code.
Could you please assist?

Hello all,
I'm looking for some guidance on adding an ADF which I will then be able to
select by AID to a SysmoISIM-SJA2. Primarily I'm curious if there's any
reason this WOULDN'T be doable before I continue down the rabbit hole of
figuring it out.
What I've tried so far is:
1) Pushing the applet to the SIM using shadysim_isim.py. It loads fine, and
when I enable SIM toolkit it appears properly on my Android device. When I
try to SELECT the AID however I get an error saying the AID doesn't exist.
2) I figure the above error is because EF.DIR doesn't include the AID, so
I update the first empty record in EF.DIR to include the AID of my applet.
When I try to SELECT the AID now I get the same error however.
I'm not sure how to proceed but I figure now is a good time to see if it is
in fact possible before spinning my wheels further. If anyone can point me
in the right direction or even just a yes/no about whether it can be done
that would be greatly appreciated.
Best,
Bryan
