[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

Lets take the 1st and 2nd 8 bits
02 - 0000 0010 ( Digit Mode bit - 0, Number Mode bit - 0)

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

8bit is Number fields
Number fields - 00 0010 10 - 0000 1010 - 0x0A (10 digits)

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.

No audio with HFP
by Scott Haynie
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.
Thanks,
Scott

[PATCH v3 0/5] udev rules update
by Philippe Nunes
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.
Philippe Nunes (5):
udev: Add rules to support ZTE MF668 dongle
udev: Add rules to support ZTE MF190 dongle
udevng.c: tty assignment according OFONO_LABEL should take precedence
udev: Add rules to support Speedup 7300 dongle
udev: Add rules to support SpeedUp 9800 dongle
