Health Device Profile hierarchy
===============================
Service org.bluez
Interface org.bluez.HealthManager
Object path /org/bluez/
Methods:
object CreateApplication(dict config)
Returns the path of the new registered application.
Dict is defined as below:
{
"DataType": uint16, (mandatory)
"Role" : ("Source" or "Sink"), (mandatory)
"Description" : string, (optional)
"ChannelType" : ("Reliable" or "Streaming")
(just for Sources, optional)
}
Application will be closed by the call or implicitly when the
programs leaves the bus.
Possible errors: org.bluez.Error.InvalidArguments
void DestroyApplication(object application)
Closes the HDP application identified by the object path. Also
application will be closed if the process that started it leaves
the bus. Only the creator of the application will be able to
destroy it.
Possible errors: org.bluez.Error.InvalidArguments
org.bluez.Error.NotFound
org.bluez.Error.NotAllowed
--------------------------------------------------------------------------------
Service org.bluez
Interface org.bluez.HealthDevice
Object path [variable prefix]/{hci0,hci1,...}/dev_XX_XX_XX_XX_XX_XX
Methods:
dict GetProperties()
Returns all properties for the interface. See the properties
section for available properties.
Posible errors: org.bluez.Error.NotAllowed
Boolean Echo()
Sends an echo petition to the remote service. Returns True if
response matches with the buffer sent. If some error is detected
False value is returned.
Possible errors: org.bluez.Error.InvalidArguments
org.bluez.Error.OutOfRange
object CreateChannel(object application, string configuration)
Creates a new data channel.
The configuration should indicate the channel quality of
service using one of this values "Reliable", "Streaming", "Any".
Returns the object path that identifies the data channel that
is already connected.
Possible errors: org.bluez.Error.InvalidArguments
org.bluez.Error.HealthError
void DestroyChannel(object channel)
Destroys the data channel object. Only the creator of the
channel or the creator of the HealtApplication that received the
data channel will be able to destroy it
Possible errors: org.bluez.Error.InvalidArguments
org.bluez.Error.NotFound
org.bluez.Error.NotAllowed
Signals:
void ChannelConnected(object channel)
This signal is launched when a new data channel is created or
when a known data channel is reconnected.
void ChannelDeleted(object channel)
This signal is launched when a data channel is deleted.
After this signal the data channel path will not be valid and
its path can be reused for future data channels.
void PropertyChanged(string name, variant value)
This signal indicates a changed value of the given property.
Properties:
object MainChannel [readonly]
The first reliable channel opened. It is needed by upper
applications in order to send specific protocol data units. The
first reliable can change after a reconnection.
--------------------------------------------------------------------------------
Service org.bluez
Interface org.bluez.HealthChannel
Object path [variable prefix]/{hci0,hci1,...}/dev_XX_XX_XX_XX_XX_XX/chanZZZ
Only the process that created the data channel or the creator of the
HealthApplication that received it will be able to call this methods.
Methods:
dict GetProperties()
Returns all properties for the interface. See the properties
section for available properties.
Posible errors: org.bluez.Error.NotAllowed
fd Acquire()
Returns the file descriptor for this data channel. If the data
channel is not connected it will also reconnect.
Possible errors: org.bluez.Error.NotConnected
org.bluez.Error.NotAllowed
void Release()
Releases the fd. Application should also need to close() it.
Possible errors: org.bluez.Error.NotAcquired
org.bluez.Error.NotAllowed
Properties:
string Type [readonly]
The quality of service of the data channel. ("Reliable" or
"Streaming")
object Device [readonly]
Identifies the Remote Device that is connected with. Maps with
a HealthDevice object.
object Application [readonly]
Identifies the HealthApplication to which this channel is
related to (which indirectly defines its role and data type).
