# DESCRIPTION
The *bluetooth* module displays information about the status of the device's bluetooth device.
The *bluetooth* module displays information about a bluetooth controller and its connections.
# CONFIGURATION
Addressed by *bluetooth*
*controller*: ++
typeof: string ++
Use the controller with the defined alias. Otherwise a random controller is used. Recommended to define when there is more than 1 controller available to the system.
*format-device-preference*: ++
typeof: array ++
A ranking of bluetooth devices, addressed by their alias. The order is from *first displayed* to *last displayed*. ++
If this config option is not defined or none of the devices in the list are connected, it will fall back to showing the last connected device.
*format*: ++
typeof: string ++
default: *{icon}* ++
default: * {status}* ++
The format, how information should be displayed. This format is used when other formats aren't specified.
*format-icons*: ++
typeof: array/object ++
Based on the device status, the corresponding icon gets selected. ++
The order is *low* to *high*. Or by the state if it is an object.
*format-disabled*: ++
typeof: string ++
This format is used when the displayed controller is disabled.
*format-off*: ++
typeof: string ++
This format is used when the displayed controller is turned off.
*format-on*: ++
typeof: string ++
This format is used when the displayed controller is turned on with no devices connected.
*format-connected*: ++
typeof: string ++
This format is used when the displayed controller is connected to at least 1 device.
*rotate*: ++
typeof: integer ++

typeof: string ++
The format, how information should be displayed in the tooltip. This format is used when other formats aren't specified.
*tooltip-format-disabled*: ++
typeof: string ++
This format is used when the displayed controller is disabled.
*tooltip-format-off*: ++
typeof: string ++
This format is used when the displayed controller is turned off.
*tooltip-format-on*: ++
typeof: string ++
This format is used when the displayed controller is turned on with no devices connected.
*tooltip-format-connected*: ++
typeof: string ++
This format is used when the displayed controller is connected to at least 1 device.
*tooltip-format-enumerate-connected*: ++
typeof: string ++
This format is used to define how each connected device should be displayed within the *device_enumerate* format replacement in the tooltip menu.
# FORMAT REPLACEMENTS
*{status}*: Status of the bluetooth device.
*{icon}*: Icon, as defined in *format-icons*.
*{num_connections}*: Number of connections the displayed controller has.
*{controller_address}*: Address of the displayed controller.
*{controller_address_type}*: Address type of the displayed controller.
*{controller_alias}*: Alias of the displayed controller.
*{device_address}*: Address of the displayed device.
*{device_address_type}*: Address type of the displayed device.
*{device_alias}*: Alias of the displayed device.
*{device_enumerate}*: Show a list of all connected devices, each on a seperate line. Define the format of each device with the *tooltip-format-enumerate-connected* ++
and/or *tooltip-format-enumerate-connected-battery* config options. Can only be used in the tooltip related format options.
# EXPERIMENTAL BATTERY PERCENTAGE FEATURE
At the time of writing, the experimental features of BlueZ need to be turned on, for the battery percentage options listed below to work.
## FORMAT REPLACEMENT
*{device_battery_percentage}*: Battery percentage of the displayed device if available. Use only in the config options defined below.
## CONFIGURATION
*format-connected-battery*: ++
typeof: string ++
This format is used when the displayed device provides its battery percentage.
*tooltip-format-connected-battery*: ++
typeof: string ++
This format is used when the displayed device provides its battery percentage.
*tooltip-format-enumerate-connected-battery*: ++
typeof: string ++
This format is used to define how each connected device with a battery should be displayed within the *device_enumerate* format replacement option. ++
When this config option is not defined, it will fall back on the *tooltip-format-enumerate-connected* config option.
