[RFC] HFP support into oFono and BlueZ
by Gustavo F. Padovan
Hi,
These patches implement the new API for the Audio Gateway in BlueZ. It
follows the last version of the HandsfreeGateway and HandsfreeAgent
Intefaces API.
The first two patches is for BlueZ and the other for oFono. You can
test it with using enable-modem and test-voicecall scripts into the
test dir of oFono.
Feel free to test it and send me your comments. We have some bugs yet.
The audio part is not working yet. We are going to work on pulseaudio
this week to get this done soon.
Regards,

CDMA SMS Handling
by Rajesh.Nagaiah＠elektrobit.com
Hi,
There was a discussion about the CDMA SMS handling and CDMA PDUs in the
IRC channel couple of days before. I would like to highlight the
differences between CDMA and GSM PDU and how we should proceed with this
from my understanding. Let me know your opinion.
Even though oFono supports +CMT and +CMTI, if we feed the incoming CDMA
PDUs to the SMS core it wont get decoded correctly, as there is
substantial differences between the GSM and CDMA SMS PDUs as described
in 3GPP2 specification C.S0015-B Short Message Service (SMS) for
Wideband Spread Spectrum Systems
For eg, the incoming PDU example that was mentioned in the IRC
discussion
+CMT: , 40,
00000210020207028CE95DCC65800601FC08150003168D30010610241830608003061010

As from the above decoding example we can see there is substantial
differences between the GSM and CDMA SMS specifications and so the SMS
atom needs many additions and needs to be heavily modified to support
also CDMA SMS handling. Currently the oFono sms file unit handles the
common and the GSM technology aspects of the SMS stack along with the
smsutils. The SMS atom has the GSM specific members, segmentation and
queuing logic. The smsutils mainly takes care of encoding/decoding of
the PDUs, which is GSM specific. As the segmentation and queuing logic
and the interface is common for both GSM and CDMA, we could reuse this
common code and add the CDMA handling into it and create a new
cdmasmsutils unit to support the CDMA SMS specifics, much like the
smsutils does already for GSM.

[PATCH v3 00/26] Escape Sequence Dectection implementation
by Guillaume Zajac
Hi,
This set of patches is an update of the previous one.
The main diff are:
- Rework Escape Sequence detection mechanism:
* we don't need a timeout to detect the 3 '+'
GUARD_TIMEOUTS only is enough.
* Be sure g_source timeout is deleted at hdlc_unref().
- GAtIO: add API to drain write buffer when hdlc is suspended
because we can't acces to GAtIO ring buffer externally.
- ppp_net: add API to suspend/resume GIOCHannel read watch
of TUN/TAP interface.
- GAtChat: add API to send <pause> +++ <pause> escape sequence
- gsmdial controls only the time interval between escape sequence
and ATO0/ATHO.
- emulator: rework ATH0 and ATO0 callbacks, add switch on emulator
type to register AT callbacks.
Kind regards,
Guillaume

Qualcomm Gobi 2000 Modem Issues
by Kai Scharwies
Hi everyone.
I ran into two issues trying to setup a data connection with a Gobi 2000 card.
The first one seems to be an error regarding simcard onlocking. After
enabling the modem test/list-modems shows the following, despite the
simcard is inserted correctly:
[ /gobi0 ]
Features = sim
Emergency = 0
Powered = 1
Lockdown = 0
Interfaces = org.ofono.SimManager
Online = 0
Model = Qualcomm Gobi 2000
Revision = D1025-STUTABGD-3600 1 [Jan 14 2010 14:00:00]
Serial = 353093033460401
Manufacturer = Qualcomm Incorporated
[ org.ofono.SimManager ]
Present = 0
Our current workaround is quitting ofono and using minicom to unlock
the sim directly, then restarting ofono.
> at+cpin?
+CPIN: SIM PIN
OK
> at+cpin="1234"
OK
$QCSIMSTAT: 1 SIM INIT COMPLETED
The second issue is not being able to activate an internet context:
(Network registration and attachment is alright)

Connecting modem /gobi0...
test/online-modem
Setting modem /gobi0 online...

If you could give me a little assisting on where to look, maybe I
would be able to contribute patches, too.
