Subject: [RFC v2 0/4] Add org.bluez.Telephony interface

Hello,

This set of patches replaces telephony drivers for HeadSet/HandsFree
Profiles by a new DBus interface (org.bluez.Telephony).
External applications, which should implement AT parsing and telephony
part of HeadSet or HandsFree Profiles, will have to register a telephony
agent using this new interface.


First patch add the new org.bluez.Telephony interface and remove
functions related to AT parsing from audio/headset.c.

Second patch remove the telephony drivers (dummy, maemo5, maemo6
and ofono), functions used by telephony drivers and no more needed
methods of org.bluez.Headset interface.

Third patch move the HS/HF AG rfcomm servers from audio/manager.c to
audio/telephony.c.
Rfcomm server for a specific profile is only started (and the related
sdp records advertised) when an agent register for it.

Fourth patch passes MediaTransport path to the agent during
NewConnection mehod call. So, telephony agent will be able to set NREC
and ringtone, which can in turn notify Pulse Audio of property changed.

What I would like to do to continue is:
- add org.bluez.HeadsetGataway, which will replace
org.bluez.HandsfreeGateway (audio/gateway.c)


Any comments appreciated

Regards

Fred

+
+ Register a TelephonyAgent to sender, the sender can

+
+ Note: If the sender disconnects its agents are
+ automatically unregistered.
+
+ possible properties:
+
+ string UUID:

+ UUID of the profile which the agent is
+ for.
+
+ uint16 Version:
+
+ Version of the profile which the agent
+ implements.
+
+ uint16 Features:
+
+ Agent supported features as defined in
+ profile spec e.g. HFP.

+ Possible Errors: org.bluez.Error.InvalidArguments

+========================
+
+Service unique name
+Interface org.bluez.TelephonyAgent
+Object path freely definable
+
+Methods void NewConnection(filedescriptor fd, dict properties)
+
+ This method gets called whenever a new connection
+ has been established. This method assumes that DBus
+ daemon with file descriptor passing capability is
+ being used.
+
+ The agent should only return successfully once the
+ establishment of the service level connection (SLC)
+ has been completed. In the case of Handsfree this
+ means that BRSF exchange has been performed and
+ necessary initialization has been done.
+
+ possible properties:
+
+ strict Device:
+
+ BlueZ remote device object.
+
+ string UUID:
+
+ Profile UUID of the connection.
+
+ uint16 Version:
+
+ Remote profile version.
+
+ uint16 Features:
+
+ Remote profile features.
+
+ string MediaTransportPath:
+
+ Optional. MediaTransport object path.
+
+ Possible Errors: org.bluez.Error.InvalidArguments
+ org.bluez.Error.Failed
+
+ void Release()
+
+ This method gets called whenever the service daemon
+ unregisters the agent or whenever the Adapter where
+ the TelephonyAgent registers itself is removed.
