[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,

[PATCH 1/3] hfp: create modem for new devices paired on runtime
by Gustavo F. Padovan
It listens the Paired property to create a modem to the recently paired
devices. It also renames added_watch to adapter_watch, a more proper
name.

[PATCH] Add support of Huawei EM770 modem
by Gu, Yang
Hi,
This patch is to enable Huawei EM770 modem, which is a full feature modem that supports voicecall, phonebook, call forwarding, call barring, etc.
There are two known parts of code that may have problem and need your comments.
1. Once connecting this modem to PC via USB, we can get 5 tty ports: ttyUSB0, ttyUSB1, ttyUSB2, ttyUSB3 and ttyUSB4. The correct way to talk to this modem is using ttyUSB2. I'm not sure if I handled this correctly in file udev.c.
2. When creating the modem, a global modem id will be appended to the name of it while constructing the path. This modem has name "huawei_em770", thus the path becomes things like "/huawei_em7700" or "/huawei_em7701". This looks strange. Need I change the name of this modem, or can we use some smarter way to append the modem id?
There is also one known issue for this modem: The return of "CSMS=?" from this modem is not compatible with spec. This is deemed as a modem issue, so the sms wouldn't work before this hardware issue get solved.
Comments are welcome!
Regards,
-Yang

[PATCH, rfc] Handle network-initiated ussd requests.
by Andrzej Zaborowski
This adds the methods on the D-bus interface to allow the
client to handle USSD requests from the network, according to 22.090.
Unfortunately this document is not clear on every point and some
details can't be implemented. This includes reporting unsupported
request to the network, unsupported language, ME busy etc, because
there isn't an AT command for that.
To be really pedantic, the Initiate() return value and the
NotificationReceived() and RequestReceived() signals should also
supply the language of the string. I also first added a "Timeout"
property with default value of 10 seconds after which oFono
automatically replies "not supported" to network-initiated requests, so
that it is compliant when no client listents to the signals, but removed
it because it isn't useful.
