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

Hi,
As I understand it is now possible to have a full software GSM stack in
software[1], with the stock osmocomBB since trx_toolkit target was
merged in OsmocomBB.
Many network side components have releases[2] and several distributions
already have part of the osmocom stack packaged[3][4].
To me having releases for osmocomBB as well also look interesting as
we could then more easily make packages for it.
It could then be used to test the other components of the stack either
with hardware[5] or with pure software, or to easily install and
keep up to date the tools (osmocon, osmoload, etc).
Would the osmocomBB be interested in doing releases? Or is there
something that is preventing that from happening (lack of interest?,
lack of time/volunteers?, technical issues?).

Hi everyone.
In MT Call flow must be as below MS BTS
<- Setup Call Confirmed -> <- Assignment Command Assignment Completed -> Alerting -> Connect->
but in implemented code in mnccms.c file immediately after sending Call Confirmed message, Alerting message is sent from MS to BTS , and this lead to ignorance of Assignment Command from BTS. WHY the procedure implemented as this ???
Dear Osmocom community,
today our mailing list server lists.osmocom.org has finally been migrated
from mailman2-on-freebsd to mailman3-on-linux. This also included a variety
of changes to DNS. I'll spare you the details, but everything _should_ be up
and running now.
* The List-Id headers should not have changed.
* all list subscriptions + user accounts have been converted.
* old 'static html' archives are still available (read only) at URLs like
https://lists.osmocom.org/pipermail/baseband-devel/
* old List URLs like https://lists.osmocom.org/mailman/listinfo/baseband-devel
are redirected to their respective modern counterparts
In case you notice any mailing list related problem, please don't hesitate to
contact me.
Happy hacking,
Harald

And add some printf at voice.c
when run bb, i used one c118, I can see that the voice data from L2/L3
to L1, and got some data from L1(the first char is 0xd) at l1ctr.c
l1ctr_traffic_ind.
All seem ok, but the called phone can not hear any data that LCR send,
and the LCR also can not get any useful data.
Especially I still can hear voice form C118 speaker that the called
phone send,
and the called phone can hear that the voice data the C118 michone send.
But I already changed the audio mode in gsm48_rr.c at gsm48_rr_init.
please give me some advice.
best regards

TDI - TP8
TCK - TP17
TDO - TP16
TMS - TP18
Looking at the board from the battery compartment side with the top of the phone pointing North/Up I see at least TP17 is near the right-hand bank of test points visible from the battery compartment. From left-to-right there I see something like: TP12, TP18?, TP16?, TP17 so it looks like I have two of the TPs I need: 17 and
18.
I can't seem to find TP6 or TP8 anywhere on the schematic.
