Bluetooth

Bluetooth

Bluetooth is a wireless technology standard for exchanging data over short distances. It is using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz. It was developed by Ericsson in 1994. Today it is used mostly to connect peripherals and smartphones to your computer.

Software

• You need to install these packages:
  • net-wireless/bluez-5.35-r1
  • sys-fs/obexfs-0.12

• dont forget to add these use-flags into your package.use:
  • app-mobilephone/obexftp bluetooth
  • dev-libs/openobex bluetooth

• Additionally you can globally enable bluetooth use flag in your make.conf, but this is not required. Dont forget to run emerge -uDN @world if you enable bluetooth use flag globally.

Bluetooth Service

• add bluetooth service to default runlevel:

  •  rc-update add bluetooth default
    

• start bluetooth service:

  •  rc-service bluetooth start
    

Controller Setup

• execute following command:

bluetoothctl

• description of commands inside bluetoothctl:
