Okay, maybe that is already enough. I saw that in drivers/telit.c there
is already some code to handle variants of the modem. The matching is
done on these strings.
Are there any vid/pid available fot his modem?
Thanks,

[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.).

Hi all,
As far as I understand, ofono doen't support IPV6 over ppp due to the fact
that IPV6 compression protocol implementation is missing.
Is that right?
Thank you,

Is it possible that epoll() does not work properly with /dev/motmdm*?
I am debugging weird problems with ofonod, and that would be an
explanation...
epoll.poll() should be returning list of file descriptors and if they
are ready. And it seems to work for ttyUSB4 but not for motmdm.
Hmm. And motmdm_cdev_poll() lacks EPOLLOUT() support, right? That
could explain things...

Motorola motmdm support
by Pavel Machek
Hi!
Motorola phones use "interesting" setup.
There's qmi and "normal" (but very buggy) AT interface on
them. Unfortunately that uses USB and uses too much power (which is a
problem on phone).
Plus there's /dev/motmdm1, motmdm3 and motmdm9, multiplexed over
serial line.
It uses subset of AT commands (good) with slightly modified
protocol... it says ":OK" instead of "OK" and puts ~ before
unsolicited messages.
Other major difference is that commands need to be sent to the right
device. It seems motmdm1 is for status and call control, and motmdm9
is for incoming sms.
I guess that right way to do this is to introduce
drivers/motorolamodem (or can we just have drivers/motorola?).
Best regards,
Pavel

Ew. So is everything related to packet services is running over QMI?
When Pavel explained that he wanted to use the weird squiggly AT
commands, I assumed you wanted to run the packet services over AT as well.

Yep, agreed. I already tried to nudge Pavel to propose something.

That's fine, as long as someone is actually using these. Right now it
is unmaintained code.

Right, but since /dev/motmdm1 would in theory belong exclusively to
oFono, you probably still need some way of sending the screen 'off'
command. So in effect you're integrating power management with the
telephony stack.

Gotcha. That makes things a bit easier.

It requires the modem to support Raw IP. Many (most?) AT command based
modems do these days, no idea about your hardware.

Depends on your definition of easier. The real reason for
GSMIOC_ENABLE_NET is speed/efficiency. In a typical 27.010 / 27.007
compliant modem you'd setup N logical AT command channels where N = 1
(minimum, but can be more if you want) + max number of active contexts.
Typically modems support 3+ of these. Once a context is activated,
you'd switch the channel into data mode via AT+CGDATA (e.g. for PPP or
raw IP) and start shoving your network packets on that channel in the
format chosen.
How are you handling data connections? PPP? Or is there some other
protocol to transfer packets back and forth?

That's great. But I think my recommendation still stands. You want GPS
state to be synchronized with the overall modem state, etc...

I believe the utilities you mention should be good enough to decode the
basics. I think someone has even tested these on a real network at some
point. But the people working on CDMA have not contributed since ~2011,
so I have no idea about the state of that code. I was considering
removing it given that CDMA is essentially defunct (or will be in a few
years).
