These patches implement the new API for the Audio Gateway in BlueZ. It
follows the last version of the HandsfreeGateway and HandsfreeAgent
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.

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
+CMT: , 40,
40 - Length of the PDU in bytes

As Digit mode bit is set to 0, Number Plan and Number Type is void

8bit is Number fields

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.
These patches implement IPv6 Control Protocol support for gatchat. The implementation is based and following gatchat's IPCP approach.
I tested with gsmdial and test-server, basic cases already work. In case anyone wants to initiate IPv6 CP address negotiation, patches to gsmdial and test-server are included.
These patches aren't complete, things yet to be done:
- Error case (Configure-Reject)
- Connect callback actions
- Proper integration with IPCP
I would appreciate your feedback.

First patch is adding cdma-netreg atom watch and status watch.
Second one is using them to check if CDMA modem is registered to the network to activate datacall.

Trying to get ofono HFP to work on my Ubuntu 11.04 box. I can
connect to the bluetooth device and initiate a voice call, but I can't
hear any audio coming from the speakers.
Went through the
instructions here: http://ofono.org/wiki/hands-free-profile . Saw
something related to configuring pulse audio, but no pointers as to how
to do that-- I do have the pulse audio package installed.
Any help is much appreciated... Let me know if specific logs would help track the issue down.
The modification I did in udevng.c to prevent overiding of the OFONO_LABEL based assignment, could break the default assignment.
I fixed this with this new patch.

I am currently trying to use ofono and I can not get how to register the
modem in a reliable way.
When I detect a modem, I set org.ofono.Modem.Powered to True.
When SimManager interface is ready, I enter the pin.
Then, I set the modem org.ofono.Modem.Online to True.
By the way, I wait for NetworkRegistration interface to be available.
When it is available, I wait for NetworkRegistration.Name to be non
empty to call NetworkRegistration.Register.
The point is setting Online property usually end with a timeout. It is
the right workflow ? Must I look for other property ?
In a few words, what is the right workflow to get a UMTS modem
registered to its default network from the moment you plug it in ?
Any piece of a clue will be appreciated :)
I have been looking for some solution to store the call history information from oFono in EDS.
In ofono-paper.txt it is mentioned as "Moblin uses oFono plugins to store
all call history information within Evolution Data Server."
But in ofono source code I could only see the history plug-in interfaces.
Where I can find the upstream plug-in code for call history storage in EDS?
Any thing related to this direction would be of great help. Thanks
Please excuse if it is already somewhere discussed in the mail archives
