BlueZ D-Bus Agent API description
**********************************
Agent Manager hierarchy
=======================
Service org.bluez
Interface org.bluez.AgentManager1
Object path /org/bluez
void RegisterAgent(object agent, string capability)
This registers an agent handler.
The object path defines the path of the agent
that will be called when user input is needed.
Every application can register its own agent and
for all actions triggered by that application its
agent is used.
It is not required by an application to register
an agent. If an application does chooses to not
register an agent, the default agent is used. This
is on most cases a good idea. Only application
like a pairing wizard should register their own
agent.
An application can only register one agent. Multiple
agents per application is not supported.
The capability parameter can have the values
"DisplayOnly", "DisplayYesNo", "KeyboardOnly",
"NoInputNoOutput" and "KeyboardDisplay" which
reflects the input and output capabilities of the
agent.
If an empty string is used it will fallback to
"KeyboardDisplay".
Possible errors: org.bluez.Error.InvalidArguments
org.bluez.Error.AlreadyExists
void UnregisterAgent(object agent)
This unregisters the agent that has been previously
registered. The object path parameter must match the
same value that has been used on registration.
Possible errors: org.bluez.Error.DoesNotExist
void RequestDefaultAgent(object agent)
This requests is to make the application agent
the default agent. The application is required
to register an agent.
Special permission might be required to become
the default agent.
Possible errors: org.bluez.Error.DoesNotExist
Agent hierarchy
===============
Service unique name
Interface org.bluez.Agent1
Object path freely definable
Methods void Release()
This method gets called when the service daemon
unregisters the agent. An agent can use it to do
cleanup tasks. There is no need to unregister the
agent, because when this method gets called it has
already been unregistered.
string RequestPinCode(object device)
This method gets called when the service daemon
needs to get the passkey for an authentication.
The return value should be a string of 1-16 characters
length. The string can be alphanumeric.
Possible errors: org.bluez.Error.Rejected
org.bluez.Error.Canceled
void DisplayPinCode(object device, string pincode)
This method gets called when the service daemon
needs to display a pincode for an authentication.
An empty reply should be returned. When the pincode
needs no longer to be displayed, the Cancel method
of the agent will be called.
This is used during the pairing process of keyboards
that don't support Bluetooth 2.1 Secure Simple Pairing,
in contrast to DisplayPasskey which is used for those
that do.
This method will only ever be called once since
older keyboards do not support typing notification.
Note that the PIN will always be a 6-digit number,
zero-padded to 6 digits. This is for harmony with
the later specification.
Possible errors: org.bluez.Error.Rejected
org.bluez.Error.Canceled
uint32 RequestPasskey(object device)
This method gets called when the service daemon
needs to get the passkey for an authentication.
The return value should be a numeric value
between 0-999999.
Possible errors: org.bluez.Error.Rejected
org.bluez.Error.Canceled
void DisplayPasskey(object device, uint32 passkey,
uint16 entered)
This method gets called when the service daemon
needs to display a passkey for an authentication.
The entered parameter indicates the number of already
typed keys on the remote side.
An empty reply should be returned. When the passkey
needs no longer to be displayed, the Cancel method
of the agent will be called.
During the pairing process this method might be
called multiple times to update the entered value.
Note that the passkey will always be a 6-digit number,
so the display should be zero-padded at the start if
the value contains less than 6 digits.
void RequestConfirmation(object device, uint32 passkey)
This method gets called when the service daemon
needs to confirm a passkey for an authentication.
To confirm the value it should return an empty reply
or an error in case the passkey is invalid.
Note that the passkey will always be a 6-digit number,
so the display should be zero-padded at the start if
the value contains less than 6 digits.
Possible errors: org.bluez.Error.Rejected
org.bluez.Error.Canceled
void RequestAuthorization(object device)
This method gets called to request the user to
authorize an incoming pairing attempt which
would in other circumstances trigger the just-works
model, or when the user plugged in a device that
implements cable pairing. In the latter case, the
device would not be connected to the adapter via
Bluetooth yet.
Possible errors: org.bluez.Error.Rejected
org.bluez.Error.Canceled
void AuthorizeService(object device, string uuid)
This method gets called when the service daemon
needs to authorize a connection/service request.
Possible errors: org.bluez.Error.Rejected
org.bluez.Error.Canceled
void Cancel()
This method gets called to indicate that the agent
request failed before a reply was returned.
