Methods void Connect()
This is a generic method to connect any profiles
the remote device supports that can be connected
to and have been flagged as auto-connectable on
our side. If only subset of profiles is already
connected it will try to connect currently disconnected
ones.
If at least one profile was connected successfully this
method will indicate success.
For dual-mode devices only one bearer is connected at
time, the conditions are in the following order:
1. Connect the disconnected bearer if already
connected.
2. Connect first the bonded bearer. If no
bearers are bonded or both are skip and check
latest seen bearer.
3. Connect last seen bearer, in case the
timestamps are the same BR/EDR takes
precedence.
Possible errors: org.bluez.Error.NotReady
org.bluez.Error.Failed
org.bluez.Error.InProgress
org.bluez.Error.AlreadyConnected
void Disconnect()
This method gracefully disconnects all connected
profiles and then terminates low-level ACL connection.
ACL connection will be terminated even if some profiles
were not disconnected properly e.g. due to misbehaving
device.
This method can be also used to cancel a preceding
Connect call before a reply to it has been received.
For non-trusted devices connected over LE bearer calling
this method will disable incoming connections until
Connect method is called again.
Possible errors: org.bluez.Error.NotConnected
void ConnectProfile(string uuid)
This method connects a specific profile of this
device. The UUID provided is the remote service
UUID for the profile.
Possible errors: org.bluez.Error.Failed
org.bluez.Error.InProgress
org.bluez.Error.InvalidArguments
org.bluez.Error.NotAvailable
org.bluez.Error.NotReady
void DisconnectProfile(string uuid)
This method disconnects a specific profile of
this device. The profile needs to be registered
client profile.
There is no connection tracking for a profile, so
as long as the profile is registered this will always
succeed.
Possible errors: org.bluez.Error.Failed
org.bluez.Error.InProgress
org.bluez.Error.InvalidArguments
org.bluez.Error.NotSupported
void Pair()
This method will connect to the remote device,
initiate pairing and then retrieve all SDP records
(or GATT primary services).
If the application has registered its own agent,
then that specific agent will be used. Otherwise
it will use the default agent.
Only for applications like a pairing wizard it
would make sense to have its own agent. In almost
all other cases the default agent will handle
this just fine.
In case there is no application agent and also
no default agent present, this method will fail.
Possible errors: org.bluez.Error.InvalidArguments
org.bluez.Error.Failed
org.bluez.Error.AlreadyExists
org.bluez.Error.AuthenticationCanceled
org.bluez.Error.AuthenticationFailed
org.bluez.Error.AuthenticationRejected
org.bluez.Error.AuthenticationTimeout
org.bluez.Error.ConnectionAttemptFailed
void CancelPairing()
This method can be used to cancel a pairing
operation initiated by the Pair method.
Possible errors: org.bluez.Error.DoesNotExist
org.bluez.Error.Failed
Properties string Address [readonly]
The Bluetooth device address of the remote device.
string AddressType [readonly]
The Bluetooth device Address Type. For dual-mode and
BR/EDR only devices this defaults to "public". Single
mode LE devices may have either value. If remote device
uses privacy than before pairing this represents address
type used for connection and Identity Address after
pairing.
Possible values:
"public" - Public address
"random" - Random address
string Name [readonly, optional]
The Bluetooth remote name. This value can not be
changed. Use the Alias property instead.
This value is only present for completeness. It is
better to always use the Alias property when
displaying the devices name.
If the Alias property is unset, it will reflect
this value which makes it more convenient.
string Icon [readonly, optional]
Proposed icon name according to the freedesktop.org
icon naming specification.
uint32 Class [readonly, optional]
The Bluetooth class of device of the remote device.
uint16 Appearance [readonly, optional]
External appearance of device, as found on GAP service.
array{string} UUIDs [readonly, optional]
List of 128-bit UUIDs that represents the available
remote services.
boolean Paired [readonly]
Indicates if the remote device is paired.
boolean Connected [readonly]
Indicates if the remote device is currently connected.
A PropertiesChanged signal indicate changes to this
status.
boolean Trusted [readwrite]
Indicates if the remote is seen as trusted. This
setting can be changed by the application.
boolean Blocked [readwrite]
If set to true any incoming connections from the
device will be immediately rejected. Any device
drivers will also be removed and no new ones will
be probed as long as the device is blocked.
string Alias [readwrite]
The name alias for the remote device. The alias can
be used to have a different friendly name for the
remote device.
In case no alias is set, it will return the remote
device name. Setting an empty string as alias will
convert it back to the remote device name.
When resetting the alias with an empty string, the
property will default back to the remote name.
object Adapter [readonly]
The object path of the adapter the device belongs to.
boolean LegacyPairing [readonly]
Set to true if the device only supports the pre-2.1
pairing mechanism. This property is useful during
device discovery to anticipate whether legacy or
simple pairing will occur if pairing is initiated.
Note that this property can exhibit false-positives
in the case of Bluetooth 2.1 (or newer) devices that
have disabled Extended Inquiry Response support.
string Modalias [readonly, optional]
Remote Device ID information in modalias format
used by the kernel and udev.
int16 RSSI [readonly, optional]
Received Signal Strength Indicator of the remote
device (inquiry or advertising).
int16 TxPower [readonly, optional]
Advertised transmitted power level (inquiry or
advertising).
dict ManufacturerData [readonly, optional]
Manufacturer specific advertisement data. Keys are
16 bits Manufacturer ID followed by its byte array
value.
dict ServiceData [readonly, optional]
Service advertisement data. Keys are the UUIDs in
string format followed by its byte array value.
bool ServicesResolved [readonly]
Indicate whether or not service discovery has been
resolved.
array{byte} AdvertisingFlags [readonly, experimental]
The Advertising Data Flags of the remote device.
dict AdvertisingData [readonly, experimental]
The Advertising Data of the remote device. Keys are
are 8 bits AD Type followed by data as byte array.
Note: Only types considered safe to be handled by
application are exposed.
Possible values:
<type> <byte array>
...
Example:
<Transport Discovery> <Organization Flags...>
0x26 0x01 0x01...
