[PATCH_v4 0/5] Private network request to ConnMan
by Guillaume Zajac
Hi,
Changelog from v3 is:
- Add private-network source/include
- ConnMan plugin is independant from emulator
- Each application that need VPN will pass a callback as argument
when private network is requested. This callback will contain the
private network settings.
Guillaume Zajac (5):
gatppp: Add new contructor to use external fd
private-network: add callback typedef drivers and settings
private-network: add request/release functions and new feature to
Makefile.am
emulator: add request/release private network calls
connman: add plugin in oFono to request request/release private
network

Read/Write EFcfis/EFcphs-cff files
by Jeevaka Badrappan
Hi,
This patch reads and writes the call forwarding unconditional status
from and to the SIM depending on the SIM file availability.
New property needs to be added due to the fact that number won't be
available from the cphs-cff file.
Incase of SIM, EFcphs-cff file holds call forwarding status and it
is represented as a flag. In case of USIM(EFcfis), we have the status
flag and also number.So, adding new property for status and using the
existing VoiceUnconditional with number will work for both SIM and USIM cases.
Other option is to have 2 properties, "VoiceUnconditional" and "Number".
"VoiceUnconditional" will have the status of the call forwarding( "enabled",
"disabled") whereas the "Number" property will have the call forwared number.
offline-online state transitions results in caching the call forwaring status
every time. To avoid this, call forwarding atom is moved to the post sim and
its moved also due to the fact that call forwarding status doesn't change in
roaming.
Regards,
Jeevaka

[PATCH] Simcom support
by Anthony Viallard
Add SIMCOM support.
I developped this with the SIM5216E chipset and ofono 1.12.
- SMS and GPRS work (in the same time) ;
- SIM card presence check ;
- No voice part because I can't test it ;
- Use default characters set instead GSM because it works like that
for what I'm doing (SMS+GPRS) (by default, the set is IRA for SIM5216E).
Also, the SIMCOM doc affraids me about problems when using GSM
(this setting causes easily software flow control (XON /XOFF) problems.).

CMGS <CTRL-Z> appears with terminate IO stream in Ofono
by Frederik Lotter
Hi Enrico,

> SMS sending.

I already have AT&C0 on both my AT chat and data channel. Maybe there is an
issue with this setup on my modem.
The root issue appears in the callback:
static gboolean received_data(GIOChannel *channel, GIOCondition cond, gpointer
data)
The g_io_channel_read_chars function gets an EOF status on read and returns
zero bytes. This happens after the CTRL-Z of the CMGS write (it appears).
What I am hoping someone can explain, is if this could be caused only by
the modem doing something on the line, or whether this could be cause by
the GLIB IO channel interpreting the CTRL-Z as a signal to close the
channel?
(I do not know which avenue to persue in debugging).
Right in the beginning of my modem init code I do:
g_at_chat_send(data->chat, "ATE0+CMEE=1", none_prefix,
NULL, NULL, NULL);
g_at_chat_send(data->chat, "AT&C0", none_prefix,
NULL, NULL, NULL);
g_at_chat_send(data->chat, "AT&D0", none_prefix,
NULL, NULL, NULL);
g_at_chat_send(data->modem, "AT&C0", none_prefix,
NULL, NULL, NULL);
g_at_chat_send(data->modem, "AT&D0", none_prefix,
NULL, NULL, NULL);
Thank for the quick reply and assistance so far.

CMGS <CTRL-Z> appears with terminate IO stream in Ofono
by Frederik Lotter
Hi Ofono experts,
I am using a UBLOX U200 modem and I wrote the driver for it some months
ago, and have since been using GPRS successfully.
I have now added the SMS feature and I am running into a problem:
It looks like once the SMS PDU byte block is sent (with CTRL-Z) the stream
disconnects.
Aux: > 0011000A8170033962660000A7044679990C<CtrlZ>
Any ideas? It looks like the g_io_channel_set_encoding() is called on both
my tty channels to RAW mode, so I am not sure why the CTRL-Z (I guess) is
causing this.

Why doesn't ofono match all +CGEV notification ? How can I implement a GPRS watchdog ?
by Viallard Anthony
Hello,
I'm looking for an issue with GPRS. I have the SIMCOM5216E module with
ofono 1.12. The problem was see in France with SFR provider. I didn't
reproduce this with another provider and in another country... But maybe
it's a question of uptime...
During a good period of time, my device is well connected through the
GPRS connection. All work perfectly. In recent log, I can see the GPRS
is reactivated several time along the weeks but the PPP is back online
soon after.
But, few days ago, I saw the GPRS connection was unusable for 10 days. I
saw the problem began the 12th February. According to different logs,
the network connectivity have began to fail since the 2th February.
Unfortunately, I couldn't get logs from ofono during the period of time
(it's an embedded device, so the size of the log file is only 64k bytes.
But it will be a good idea for the future to increment it ...). However,
the device had others logs. I could see the log from our program that
deals with ofono (it sends dbus commands and listen for dbus signals)
and I saw there is a blank period from the 2th to the 12th. It's like
ofono or the module was dead.
So, I begin to read the code, especially the simcom driver, to see if I
miss something. And I see something weird.
According to the SIMCOM AT document, the +CGEV notification can be send
with this list of event:
REJECT
NW REACT
NW DEACT
ME DEACT
NW DETACH
ME DETACH
NW CLASS
ME CLASS
But in gprs-context.c, I see we deal only with the "NW DETACH" event.
Maybe It's the point. Maybe the modem send to ofono an another event and
therefore ofono begins to be in incorrect state about the GPRS
connection... Is it possible ?
Otherwise, I'm thinking about implement a GPRS watchdog. Does it exist
an AT command which could do that ? My idea is to send an AT command
each XX period of time and check the GPRS connection is really here.
Regards,
Anthony Viallard.

oFono handles many other services so restarting would have undesirable effects.
For a moment clients would think there is no telephony at all: no SIM,
no cellular signal strength, no voice/emergency calls, no SIM ATK etc.

Generally speaking I agree with the point of view. The main point was
not the 'live' part, but to allow running provisioning again, e.g. if
user has set wrong ones.
FYI a MMS context may be active using a correct APN but messages don't
flow due to a wrong proxy. In such a case context remains active for
some time.

When ofono already implements the initial provisioning logic it is not
tempting to duplicate it but instead trigger it again.
(A more suitable name for the new method could be "ProvisiongContext"
or similar.)
If reverting provisioned settings is done by creating a new empty
context, one would still want to run ofono provisioning for that
(ofono restart not an option).

Thanks for your feedback Denis, I appreciate it. All tips to make
changes more upstream-worthy, or if not then otherwise better, are
welcome.
Thanks

[PATCH 0/2] Add ResetProperties method to ConnectionContext interface
by Tommi Kenakkala
In some cases it is useful to reset connection context settings back to ones
ofono provisioning resolved initially.
What's your opinion on the API design, implementation and use-case described
next?
Deactivation of the context is obviously mandatory. The reasoning for placing
this into ofono is handling client requests consistently and avoiding race
conditions. Using this approach ofono does not re-activate the context, that's
done by ConnMan or whatever connection manger the system uses.
Ps. Patches on behalf of Slava whose emails didn't get through to the mailing
list.

Re: Which desktop linux distribution uses ofono natively?

I’ve brought up ofono and econnman on Ubuntu 14.04.01 LTS
using the packages available via apt-get on a generic Intel laptop.
Haven’t tested Bluetooth, but it’s working with wifi and wired ethernet. I’m now
trying to figure out how to add “cellular” to the technologies supported by ofono.
After upgrading the linux kernel to 3.19, I can see wwan0 showing up
in /sys/class/net so the device (a Huawei E3272 LTE dongle) is being
detected by the kernel properly (and it works if I use sakis3g).
I think there was a Huawei specific bug in the shipped version of the
kernel that blocked me earlier.
Short of reading the ofono code - which I can do later this week - any pointers
on connecting cellular with ofono?

My target board isn’t ready yet. I could try an experiment with an old
Raspberry Pi B.
thanks!
