1 Gateway hierarchy 2 ======================== 3 4 Service org.bluez 5 Interface org.bluez.HandsfreeGateway 6 Object path [variable prefix]/{hci0,hci1,...}/dev_XX_XX_XX_XX_XX_XX 7 8 This interface is available for remote devices which can function in the Audio 9 Gateway role of the HFP profiles. It is intended to be used with external 10 telephony stacks / handlers of the HFP protocol. 11 12 Methods void Connect() 13 14 Connect to the AG service on the remote device. 15 16 void Disconnect() 17 18 Disconnect from the AG service on the remote device 19 20 dict GetProperties() 21 22 Returns all properties for the interface. See the 23 properties section for available properties. 24 25 void RegisterAgent(object path) 26 27 The object path defines the path the of the agent 28 that will be called when a new Handsfree connection 29 is established. 30 31 If an application disconnects from the bus all of its 32 registered agents will be removed. 33 34 void UnregisterAgent(object path) 35 36 This unregisters the agent that has been previously 37 registered. The object path parameter must match the 38 same value that has been used on registration. 39 40 Possible Errors: org.bluez.Error.Failed 41 org.bluez.Error.InvalidArguments 42 43 44 Signals PropertyChanged(string name, variant value) 45 46 This signal indicates a changed value of the given 47 property. 48 49 Properties string State [readonly] 50 51 Indicates the state of the connection. Possible 52 values are: 53 "disconnected" 54 "connecting" 55 "connected" 56 "playing" 57 58 HandsfreeAgent hierarchy 59 =============== 60 61 Service unique name 62 Interface org.bluez.HandsfreeAgent 63 Object path freely definable 64 65 Methods void NewConnection(filedescriptor fd) 66 67 This method gets called whenever a new handsfree 68 connection has been established. The objectpath 69 contains the object path of the remote device. This 70 method assumes that DBus daemon with file descriptor 71 passing capability is being used. 72 73 The agent should only return successfully once the 74 establishment of the service level connection (SLC) 75 has been completed. In the case of Handsfree this 76 means that BRSF exchange has been performed and 77 necessary initialization has been done. 78 79 Possible Errors: org.bluez.Error.InvalidArguments 80 org.bluez.Error.Failed 81 82 void Release() 83 84 This method gets called whenever the service daemon 85 unregisters the agent or whenever the Adapter where 86 the HandsfreeAgent registers itself is removed. 87
