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,
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 Osmocom developers,
please see the attached messages. I'm getting dozens of these since yesterday,
it appears likely some regression was merged? Any help is appreciated.
Regards,
Harald

Hi all,
during the past couple of days, there have been a high number of build
failures due to 'illegal instruction'. I checked about a handful of
them, and they all happened on build2.osmocom.org.
On the machine nothing strange could be observed, i.e. no oopses or the like.
Also, debsums didn't report any broken compiler binaries.
I've taken the builds slaves offline and asked for the machine to be replaced
(disks will be moved so no data loss expected).
Let's hope that fixes it. If not, I guess a full re-install of OS +
lxc's (via ansible) is up next.

Ha, completely forgot about that. I tweaked that wiki page a bit to be less of
a pitfall to newcomers (hopefully).
BTW, off-list, ah med wrote to us that he figured out to use osmo-trx and
osmo-bts-trx but still struggles with the BladeRF. We asked him to come back
on-list or visit IRC for further questions.

after setting the osmo-bts-trx and osmo-trx-uhd and with a BLADERF X40 ,i
just got this when running my network !
every other services like HLR,MSC...work perfectly and just the
osmo-trx-uhd have some problems with the bladerf !

Hi,

it looks like you have installed a very old libosmocore.
You need to remove it (make uninstall) and install the
recent one from the upstream (not from OsmocomBB).
With best regards,
Vadim Yanitskiy.
Hello,
Unfortunately I have come up to the problem that I can't google myself and
my friends can't help with either. Maybe it has something to do with readme
saying that libsomocore in the git I pulled isn't for system wide
installation but when I make the osmocombb src then it spits out this:
configure: error: Package requirements (libosmovty >= 0.10.0) were not met:
Requested 'libosmovty >= 0.10.0' but version of Osmocom VTY Interface
Library is UNKNOWN
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables LIBOSMOVTY_CFLAGS
and LIBOSMOVTY_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
Makefile:94: recipe for target 'host/layer23/Makefile' failed
make: *** [host/layer23/Makefile] Error 1
If I need to get a different libosmocore could you provide it to me?
Thank you
