Bluetooth speakers can easily be used with the Intel Edison and other Linux single-board embedded computers to wirelessly play sound. Create a homebrew Sonos®-like speaker system where the link between computer and speaker is via Bluetooth. After connecting to Bluetooth device from Linux terminal, setup BlueZ like:
apt install bluez
Then setup Alsa or Pulseaudio to use the Bluetooth audio device, whether by GUI or command line.
For Yocto on Intel Edison, BlueZ is installed by:
opkg install alsa-utils kernel-module-snd-usb-audio bluez5 gstreamer pulseaudio opkg install kernel-module-ftdi-sio
