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.

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 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

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

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

Hi all!
[please follow-up-to the openbsc(a)lists.osmocom.org mailing list, if
there is any discussion, we don't want to drag it over tons of mailing
lists in parallel]
Some weeks ago, I created https://osmocom.org/issues/5397 but it seems nobody
noticed the ticket or had any comments to it.
So let me post this as RFC here on the mailing list:
In the past, we had a gitolite/gitosis setup, which was fine in the
early days of git, but it means that people cannot easily create new
repositories, see who has permissions, and we cannot delegate ownership.
Even updating SSH keys requires manual interaction of a sysadmin like
me.
I would therefore suggest to migrate git.osmocom.org to gitea[1]
This would allow the following features:
* users can self-create any number of personal repositories (like gitlab/github)
* we can create 'organizations' along the line of reasonably independent
osmocom member projects like op25, who can then manage their own
repos/permissions/...
* gitea can link to redmine wiki and redmine issue trackers (rather than
using its own built-in)
For those repositories hosted in gerrit (mainly CNI), we would still
keep git.osmocom.org a read-only mirror, like we do it right now.
For those repositories not hosted in gerrit, users/projects could then
accept merge requests in gitea. Coupling this with 3rd party
authentication via github/gitlab/etc should make it easier for the
occasional contributor to submit changes.
There is a downside, of course; A lot of repo URLs have to change. Most
of our current repositories are at git.osmocom.org/project.git while
gitea follows a git.osmocom.org/organization/project.git scheme. I'm not
sure there is any way to help to mitigate this...
Any thoughts, comments?

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

Hello Harald & Co.
This sounds like a positive development. If there is any resulting trouble(s) we'll deal with it if / as nec.
Let me take this opportunity to thank you and Osmocom for hosting OP25.

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
Thanks,
