P2P Service Manager hierarchy
=============================
Service net.connman.iwd
Interface net.connman.iwd.p2p.ServiceManager [Experimental]
Object path /net/connman/iwd
Methods void RegisterDisplayService(dict properties)
Register a Wi-Fi Display service handler. An
application can register as implementing this
P2P-based service to make IWD advertise local WFD
capability to peers, expose discovered peers' WFD
capabilities for each DBus peer object, and
validate the peer's WFD properties during a
connection setup. Once a connection is established
to a peer that was available for a WFD Session the
application is responsible for continuing the WFD
session establishment by setting up the TCP
connection, performing WFD capability exchange and
negotiation, Link Content Protection setup and
session start. When the session is torn down,
the application is responsible for calling the
Disconnect method on the net.connman.iwd.p2p.Peer
interface of the peer object.
Registering a service will have no effect on
existing connections.
The net.connman.iwd.p2p.Display interface is
going to be attached to discovered peer objects of
those peers that are available for a WFD session.
The properties argument to this method, who's DBus
signature is a{sv}, may contain any of the
properties on that interface as listed below.
Note that there's currently no way to select the
role for a specific connection so IWD will refuse
to connect to a dual-role peer if the local WFD
device is also dual-role capable.
Possible Errors: [service].Error.InvalidArguments
[service].Error.AlreadyExists
[service].Error.NotSupported
void UnregisterDisplayService()
Unregister a WFD service handler.
Possible Errors: [service].Error.InvalidArguments
[service].Error.NotFound

Properties boolean Source [readonly]
Whether the peer represented by the object is
a WFD source.
boolean Sink [readonly]
Whether the peer represented by the object has
a WFD sink capability. At least one of this and
'Source' should be true.
uint16 Port [readonly, optional]
WFD Session Management Control port -- a TCP port
number. Only present/allowed if Source is true.
boolean HasAudio [readonly, optional]
Whether audio rendering is supported. Only
present/allowed if Sink is true.
boolean HasUIBC [readonly]
Whether WFD Device supports UIBC or User Input
Back Channel communication.
boolean HasContentProtection [readonly]
