Indeed. If you connect a "Bluetooth host controller" directly to your
computer (usually by USB), then it will show up in the XFCE Bluetooth
manager and you can configure everything from there: connect to
specific devices, etc. When you use a device like yours that has a
Bluetooth host controller inside it but has only an audio connection to
your computer, the UI is typically minimal (e.g., a single button) and
you may not be able to do things like tell it to make a Bluetooth
connection to a specific device.
The most popular other uses for Bluetooth are:
- Mouse and keyboard input
- Networking. It's pretty slow but can be useful if your Wi-Fi is
taken for something else. For example, I use a Bluetooth network to
synchronize my personal information management applications between my
phone and my computer via various HTTPS- and SSH-based protocols
without relying on any external service.
Bluetooth LE (low energy. or BTLE) is used by a wide range of small battery-powered
devices (heart-rate sensors, bicycle cadence, etc) and some more specialized devices
such as indoor cycling machines. There are temperature and moisture sensors for
your garden.
