# NAME
waybar - bluetooth module
# DESCRIPTION
The *bluetooth* module displays information about the status of the device's bluetooth device.
# CONFIGURATION
Addressed by *bluetooth*
*interval*: ++
typeof: integer ++
default: 60 ++
The interval in which the network information gets polled (e.g. signal strength).
*format*: ++
typeof: string ++
default: *{icon}* ++
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.
*rotate*: ++
typeof: integer ++
Positive value to rotate the text label.
*max-length*: ++
typeof: integer ++
The maximum length in character the module should display.
*on-click*: ++
typeof: string ++
Command to execute when clicked on the module.
*on-click-middle*: ++
typeof: string ++
Command to execute when middle-clicked on the module using mousewheel.
*on-click-right*: ++
typeof: string ++
Command to execute when you right clicked on the module.
*on-scroll-up*: ++
typeof: string ++
Command to execute when scrolling up on the module.
*on-scroll-down*: ++
typeof: string ++
Command to execute when scrolling down on the module.
*smooth-scrolling-threshold*: ++
typeof: double ++
Threshold to be used when scrolling.
*tooltip*: ++
typeof: bool ++
default: *true* ++
Option to disable tooltip on hover.
*tooltip-format*: ++
typeof: string ++
The format, how information should be displayed in the tooltip. This format is used when other formats aren't specified.
# FORMAT REPLACEMENTS
*{status}*: Status of the bluetooth device.
*{icon}*: Icon, as defined in *format-icons*.
# EXAMPLES
```
"bluetooth": {
"format": "{icon}",
"format-alt": "bluetooth: {status}",
"interval": 30,
"format-icons": {
"enabled": "",
"disabled": ""
}
"tooltip-format": "{status}"
}
```
