[General]

# Defaults to 'BlueZ X.YZ', if Name is not set here and plugin 'hostname' is not loaded.
# The plugin 'hostname' is loaded by default and overides the Name set here so
# consider modifying /etc/machine-info with variable PRETTY_HOSTNAME=<NewName> instead.
#Name = BlueZ

# Default device class. Only the major and minor device class bits are
# considered. Defaults to '0x000000'.
#Class = 0x000100

# How long to stay in discoverable mode before going back to non-discoverable
# The value is in seconds. Default is 180, i.e. 3 minutes.
# 0 = disable timer, i.e. stay discoverable forever
#DiscoverableTimeout = 0

# Always allow pairing even if there are no agent registered
# Possible values: true, false
# Default: false
#AlwaysPairable = false

# How long to stay in pairable mode before going back to non-discoverable
# The value is in seconds. Default is 0.
# 0 = disable timer, i.e. stay pairable forever
#PairableTimeout = 0

# Use vendor id source (assigner), vendor, product and version information for
# DID profile support. The values are separated by ":" and assigner, VID, PID
# and version.
# Possible vendor id source values: bluetooth, usb (defaults to usb)
#DeviceID = bluetooth:1234:5678:abcd

# Do reverse service discovery for previously unknown devices that connect to
# us. For BR/EDR this option is really only needed for qualification since the
# BITE tester doesn't like us doing reverse SDP for some test cases, for LE
# this disables the GATT client functionally so it can be used in system which
# can only operate as peripheral.
# Defaults to 'true'.
#ReverseServiceDiscovery = true

# Enable name resolving after inquiry. Set it to 'false' if you don't need
# remote devices name and want shorter discovery cycle. Defaults to 'true'.
#NameResolving = true

# Enable runtime persistency of debug link keys. Default is false which
# makes debug link keys valid only for the duration of the connection
# that they were created for.
#DebugKeys = false

# Restricts all controllers to the specified transport. Default value
# is "dual", i.e. both BR/EDR and LE enabled (when supported by the HW).
# Possible values: "dual", "bredr", "le"
#ControllerMode = dual

# Enables Multi Profile Specification support. This allows to specify if
# system supports only Multiple Profiles Single Device (MPSD) configuration
# or both Multiple Profiles Single Device (MPSD) and Multiple Profiles Multiple
# Devices (MPMD) configurations.
# Possible values: "off", "single", "multiple"
#MultiProfile = off

# Permanently enables the Fast Connectable setting for adapters that
# support it. When enabled other devices can connect faster to us,
# however the tradeoff is increased power consumptions. This feature
# will fully work only on kernel version 4.1 and newer. Defaults to
# 'false'.
#FastConnectable = false

# Default privacy setting.
# Enables use of private address.
# Possible values: "off", "device", "network"
# "network" option not supported currently
# Defaults to "off"
# Privacy = off

# Specify the policy to the JUST-WORKS repairing initiated by peer
# Possible values: "never", "confirm", "always"
# Defaults to "never"
#JustWorksRepairing = never

# How long to keep temporary devices around
# The value is in seconds. Default is 30.
# 0 = disable timer, i.e. never keep temporary devices
#TemporaryTimeout = 30

# Enables the device to issue an SDP request to update known services when
# profile is connected. Defaults to true.
#RefreshDiscovery = true

[Controller]
# The following values are used to load default adapter parameters.  BlueZ loads
# the values into the kernel before the adapter is powered if the kernel
# supports the MGMT_LOAD_DEFAULT_PARAMETERS command. If a value isn't provided,
# the kernel will be initialized to it's default value.  The actual value will
# vary based on the kernel version and thus aren't provided here.
# The Bluetooth Core Specification should be consulted for the meaning and valid
# domain of each of these values.

[GATT]

[Policy]
#
# The ReconnectUUIDs defines the set of remote services that should try
# to be reconnected to in case of a link loss (link supervision
# timeout). The policy plugin should contain a sane set of values by
# default, but this list can be overridden here. By setting the list to
# empty the reconnection feature gets disabled.

# ReconnectAttempts define the number of attempts to reconnect after a link
# lost. Setting the value to 0 disables reconnecting feature.
#ReconnectAttempts=7

# ReconnectIntervals define the set of intervals in seconds to use in between
# attempts.
# If the number of attempts defined in ReconnectAttempts is bigger than the
# set of intervals the last interval is repeated until the last attempt.

# AutoEnable defines option to enable all controllers when they are found.
