[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.

Enabling/disabling the GPS part of a Huawei EM770W
by Florian Mayer (Mayer Electronics)
Hello folks,
is it possible to enable / disable the GPS part of a Huawei EM770W 3G
modem through a DBUS command? It is done with the command AT^WPDGP and
AT^WPEND on the modem (tested it on PCUI port). Or is it possible to
send generic AT commands through DBUS?

[PATCH 0/1] Patch Description
by Yang Gu
This patch is to cancel the pending sms via D-Bus. Till now, I'm still not sure what kind of sms should be cancelled. In theory, one message, or part of it, would be sent by oFono can be cancelled. For some examples: Any part of a message that has never been sent can be cancelled; one message was sent but failed, we can cancel before retry; One message is split into several pieces, we can cancel before all of them are sent.
In current patch, I only cancel the sms that has never been sent. I wonder if it's enough or I should handle all the situations above.
Another question here is about the existed code. There is a hashtable "messages" in struct ofono_sms. Can we store the state in the tx_queue_entry, and remove the hashtable thoroughly to make the code more simple?

[PATCH 0/9] SMS history plugin.
by Oleg Zhurakivskyy
Hello,
Please find the SMS history plugin set of patches. The plugin makes it
possible for an application/multiple applications to register for
incoming/outgoing SMS messages and receive them over D-Bus.
The SMS history itself is maintained by a separate application,
which registers to ofonod using this interface.

unsolicited multiline result
by Petteri Tikander
This patch is for handling multiline unsolicited result-codes.
So state-machine used for handling result-bytes (gsmv1_feed) is set to the multiline-response
state. Otherwise next lines from the result-buffer are not handled correctly,
and response-handling will get stuck.
In the other hand, this correction keeps result-handling still unchanged.
So single line is notified to the upper level (atoms) at a time, not all lines of the result.
For instance: network-emergency numbers cannot be collect to the one single notification yet.

[PATCHv2] plugin: Add ste modem initd integration
by Sjur Brændeland
From: Sjur Brændeland <sjur.brandeland(a)stericsson.com>
This patch introduces auto discovery of ST-Ericsson modems.
ST-Ericsson modems (M5XX, M57XX, M7XX, M74XX) are managed by a
Modem Init Daemon responsible for start, power cycles,
flashing etc. This STE plugin monitors the modem state exposed
from the Modem Init Damon's Dbus API. When the modem is in state
"on" the STE modem is created and registered. Multiple modem
instances, and reset handling is supported.
---
Changes:
- Support for multiple STE modems.
- Better naming of STE modem instances, using received dbus path.
- CAIF Link layer to use for AT channels specified pr modem instance.
- Added support for reset.

Discussion on CTM enhancement
by Predon, Frederic
Hi,
As we are currently implementing the CTM modem driver for ifxmodem, I would like to bring a couple of things in the discussion.
Today, patches for our modem driver are ready by before submitting them on the mailing list, I have 2 items to discuss:
1) First, it might a good proposal to merge the TextTelephony and the AudioSettings atoms. Enabling and disabling CTM on a platform require to configure the audio settings on the modem side (audio routing parameters changes). Today, in my patches, I have nearly the same code as the AudioSetting modem driver for configuring the audio. Another proposal would be that the TextTelephony atom indicates to the AudioSetting atom that CTM is enable or disable but that would be good also to merge the 2.
Any idea?
2) Secondly, I think that 2 properties can be added in the TextTelephony atom and/or the AudioSetting atom (or the "merged" atom described in 1). The first property is when the device receives an incoming CTM call. Even if the type is still a voice call, upper layers should be notified that the incoming is a TTY call to display some UI stuff or to turn on the TTY mode in case the device is not already TTY enabled (this is totally UI dependant but at least we leave the flexibility to the UI to decide).
The second property is for MO calls. Remote user can accept the call as a TTY enable device or not. This is supported by the standard. In our case, we are receiving unsolicited AT commands "CTM CALL" when the remote party has accepted the call as a TTY enabled device and "NO CTM CALL" when the remote has accepted the call but his device is not TTY enabled.
Let me know your thinking
Regards
Fred
