[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.

Bluetooth HF role
by Mikel Astiz
Hi all,
I'm trying to understand the features currently supported by oFono
regarding the handsfree role in Bluetooth/HFP. My first impression
looking at the source code is that some HFP functionality might be
missing, but I would rather have your confirmation.
Some examples I've found so far are the following:
1. Response and hold (AT+BTRH=0)
2. Redial last number (AT+BLDN)
3. Retrieval of supported Bluetooth features for a certain modem/device
(AT+BRSF)
Could you clarify which (if any) of these features are currently
supported by oFono?
In general, is there any documented list of unsupported features?
Regards,
Mikel

[PATCH v2 0/5] udev rules update
by Philippe Nunes
For Speedup dongles, the aux channel is not necessarily on the last interface (as for Speedup 8000)
So, I kept the actual logic (modem is assigned on the last interface) and I added two rules for Speedup 7300 and Speedup 9800
I modified also udevng.c in order to avoid aux/modem channel assignment according OFONO_LABEL to be overridden by the default assignment.
Note that for ZTE dongles, this overriding can't occur.
