Marcel,
That "flame" was uncalled for. I have attached file bluez-utils-3.30/hcid/dbus-api.txt
The section describing the org.bluez.Adapter interface contains the following (emphasis added):
void DiscoverDevices()
This method starts the device discovery procedure. This
includes an inquiry procedure and remote device name
resolving.
On start up this process will generate a DiscoveryStarted
signal and then return ***RemoteDeviceFound*** and also
***RemoteNameUpdated*** signals. If the procedure has been
finished an DiscoveryCompleted signal will be sent.
Possible errors: org.bluez.Error.NotReady
org.bluez.Error.Failed
org.bluez.Error.InProgress
org.bluez.Error.NoSuchAdapter
void DiscoverDevicesWithoutNameResolving()
This method starts the device discovery procedure. This
includes an inquiry and an optional remote device name
resolving. The remote names can be retrieved with
GetRemoteName and in the case a name doesn't exist it
will be queued for later resolving and GetRemoteName
will return an error.
While this procedure is running every found device
will be returned with ***RemoteDeviceFound***. While
DiscoverDevices() automatically resolves unknown
devices names and sends ***RemoteNameUpdated*** in this
case it will only happen if GetRemoteName has been
called and no previously stored name is available.
Possible errors: org.bluez.Error.NotReady
org.bluez.Error.Failed
org.bluez.Error.InProgress
org.bluez.Error.NoSuchAdapter
Note well: not "DeviceFound", but "RemoteDeviceFound".
The file I attached is the only dbus-api-txt found in the entire bluez-utils-3.30 tree. So, it appears the documentation is out of
date; after digging into the code at adapter.c, I found signals DeviceCreated, DeviceRemoved, and DeviceFound in the adapter_signals
table. I will implement "catches" for them, now, and expect that this problem will go away.
So, thanks in advance,
DS

why don't you actually read the API documentation. Nobody said that
you can expect RemoteDeviceFound and RemoteNameUpdated on /hci0 and
you really can't. They are not sent. You get a DeviceFound signal.

Constant definitions
====================
The class of device definition from the Bluetooth specification divides into
three different parts. It the major class, the minor class and the service
classes. The D-Bus interface will always use string constants to identify
any of these classes.
Service classes positioning, networking, rendering, capturing,
object transfer, audio, telephony, information
Major classes miscellaneous, computer, phone, access point,
audio/video, peripheral, imaging, wearable, toy,
uncategorized
Minor classes computer uncategorized, desktop, server, laptop, handheld,
palm, wearable
Minor classes phone uncategorized, cellular, cordless, smart phone,
modem, isdn
Minor classes access point fully, 1-17 percent, 17-33 percent,
33-50 percent, 50-67 percent, 67-83 percent,
83-99 percent, not available
Minor classes audio video uncategorized, headset, handsfree,microphone,
loudspeaker, headphones, portable audio, car audio,

Error hierarchy
===============
Interface org.bluez.Error
Shared Errors (Can be thrown by hcid or any bluetooth service)
DeviceUnreachable
The remote device is either powered down or out of range.
AlreadyConnected
A connection request has been received on an already
connected device.
ConnectionAttemptFailed
An unexpected error (other than DeviceUnreachable) error
has occured while attempting a connection to a device.
NotConnected
The remote device is not connected, while the method call
would expect it to be, or is not in the expected state to
perform the action.
InProgress
Error returned if an operation is in progress. Since
this is a generic error that can be used in various
situations, the error message should be more clear
about what is in progress. For example "Bonding in
progress".
InvalidArguments
The DBUS request does not contain the right number of
arguments with the right type, or the arguments are there
but their value is wrong, or does not makes sense in the
current context.
OutOfMemory
Error returned when a memory allocation via malloc()
fails. This error is similar to ENOMEM.
NotAvailable
Error returned when a specified record is not
available.
NotSupported
The remote device does not support the expected
feature.
AlreadyExists
One of the requested elements already exists
DoesNotExist
One of the requested elements does not exist
Canceled
The operation was canceled.
Failed
This is a the most generic error.
It is thrown when something unexpected happens.
Hcid specific Errors (Can be thrown by hcid only)
NotReady
Error returned when the adapter is DOWN.
UnknwownMethod
This is an experimental method.
NotAuthorized
Error returned when the caller of a method is not
authorized. This might happen if a caller tries to
terminate a connection that it hasn't created.

stay in discoverable/limited mode forever.
The default value for the discoverable timeout should
be 180 seconds (3 minutes).
Possible errors: none
void SetDiscoverableTimeout(uint32 timeout)
Sets the discoverable timeout in seconds. A value of
zero disables the timeout and the adapter would be
always discoverable/limited.
Changing this value doesn't set the adapter into
discoverable/limited mode. The SetMode method must be used.
Possible errors: org.bluez.Error.NotReady

string GetRemoteName(string address)
Get the remote device's name. This request returns always
a cached name. The service daemon is responsible for
updating the cache.
NotAvailable error is returned if the name is not in
the cache. But if there is a discovery running, then
this function will return RequestDeferred. In this
case the service daemon will queue the request and
it will try to resolve the name at the next possible
opportunity. On success a RemoteNameUpdated signal will
be send and if a failure happens it will be indicated by
a RemoteNameFailed signal.
If this is an empty string, the UI might want to
display the BD_ADDR instead.

If a link key for this adapter already exists, this
procedure should fail instead of trying to create a
new pairing.
If no connection to the remote device exists, a
low-level ACL connection must be created.
This function will block and the calling application
should take care of setting are higher timeout. This
might be needed in case of a page timeout from the
low-level HCI commands.
In case of success it will send a BondingCreated
signal.

Security hierarchy
==================
Service org.bluez
Interface org.bluez.Security
Object path /org/bluez or /org/bluez/{hci0,hci1,...}
Methods void RegisterDefaultPasskeyAgent(string path)
This registers the default passkey agent. It can
register a passkey for all adapters or for a
specific device depending on with object path has
been used.
The path parameter defines the object path of the
passkey agent that will be called when a passkey
needs to be entered.
If an application disconnects from the bus all
registered passkey agent will be removed.
Possible errors: org.bluez.Error.AlreadyExists
void UnregisterDefaultPasskeyAgent(string path)
This unregisters a default passkey agent that has
been previously registered. The object path and
the path parameter must match the same values that
has been used on registration.
Possible errors: org.bluez.Error.DoesNotExist
void RegisterPasskeyAgent(string path, string address)
This registers the application passkey agent that
will be used for any application specific passkey
tasks.
The path parameter defines the object path of the
passkey agent that will be called when a passkey
needs to be entered. The address defines the remote
device that it will answer passkey requests for.
If an application disconnects from the bus all
registered passkey agent will be removed. It will
also be unregistered after a timeout and if the
pairing succeeds or fails. The application has to
take care of that it reregisters the passkey agent.
Possible errors: org.bluez.Error.AlreadyExists
void UnregisterPasskeyAgent(string path, string address)
This unregisters a passkey agent that has been
previously registered. The object path and the path
and address parameter must match the same values
that has been used on registration.
The method is actually only needed if an application
wants to removed the passkey agent and don't wanna
wait for the automatic timeout.
Possible errors: org.bluez.Error.DoesNotExist
void RegisterDefaultAuthorizationAgent(string path)
This registers the default authorization agent. It can
register an authorization agent for all adapters or
for a specific one depending on which object path has
been used.
The path parameter defines the object path of the
authorization agent that will be called when an
authorization request needs to be answered.
void UnregisterDefaultAuthorizationAgent(string path)
This unregisters a default authorization agent that has
been previously registered. The path parameter must
match the same value that has been used on
registration.
PasskeyAgent hierarchy
======================
Service unique name
Interface org.bluez.PasskeyAgent
Object path freely definable
Methods string Request(string path, string address, boolean numeric)
This method gets called when the service daemon
needs to get the passkey for an authentication. The
return value is actual passkey.
The first argument contains the path of the local
adapter and the second one the remote address. The
third argument signals if a numeric PIN code is
expected or not. The default is a 1 to 16 byte PIN
code in UTF-8 format.
Possible errors: org.bluez.Error.Rejected
org.bluez.Error.Canceled
void Confirm(string path, string address, string value)
This method gets called when the service daemon
needs to verify a passkey. The verification is
done by showing the value to the passkey agent
and returning means a successful confirmation.
In case the values don't match an error must
be returned.
Possible errors: org.bluez.Error.Rejected
org.bluez.Error.Canceled
void Display(string path, string address, string value)
This method gets called when the service daemon
needs to display the passkey value. No return
value is needed. A successful paring will be
indicated by the Complete method and a failure
will be signaled with Cancel.
void Keypress(string path, string address)
This method indicates keypresses from the remote
device. This can happen when pairing with a keyboard.
void Complete(string path, string address)
This method gets called to indicate that the
authentication has been completed.
void Cancel(string path, string address)
This method gets called to indicate that the
authentication request failed before a reply was
returned by the Request method.
void Release()
This method gets called when the service daemon
unregisters a passkey 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.
AuthorizationAgent hierarchy (experimental)
===========================================
Service unique name
Interface org.bluez.AuthorizationAgent
Object path freely definable
Methods void Authorize(string adapter_path, string address,
string service_path, string uuid)
This method gets called when the service daemon wants
to get an authorization for accessing a service. This
method should return if the remote user is granted
access or an error otherwise.
The adapter_path parameter is the object path of the
local adapter. The address, service_path and action
parameters correspond to the remote device address,
the object path of the service and the uuid of the
profile.
Possible errors: org.bluez.Error.Rejected
org.bluez.Error.Canceled
void Cancel(string adapter_path, string address,
string service_path, string uuid)
This method cancels a previous authorization request.
The adapter_path, address, service_path and uuid
parameters must match the same values that have been
used when the Authorize() method was called.
void Release()
This method gets called when the service daemon
unregisters an authorization 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.
