Bluetooth on AcreetionOS

Cinnamon’s bluetooth applet handles day-to-day pairing once the stack is running (it is, by default, when hardware exists).

Quick start

  1. Click the bluetooth tray icon → toggle on.

  2. Put your device in pairing mode.

  3. Click Add device, pick it, confirm the code.

Prefer terminal?

bluetoothctl power on
bluetoothctl devices                # after scanning: scan on
bluetoothctl pair MAC
bluetoothctl trust MAC              # auto-reconnect future boots
bluetoothctl connect MAC

Audio devices

Headphones/speakers need the PipeWire bluetooth backend — preinstalled on AcreetionOS. If sound routes but quality is poor:

pactl list cards | grep -i profile     # see available profiles
pactl set-card-profile bluez_card.XX a2dp-sink    # high-quality A2DP

Mic-on-headset (HFP) needs the bluez-plugins extras; A2DP-only is the common case for listening.

Keyboard / mouse / gamepad

Pair like any device. Input devices should be `trust`ed so they reconnect without re-pairing each boot.

Troubleshooting

Symptom Fix attempt

No adapter found

lsusb/lspci to confirm hardware exists; sudo modprobe btusb; some laptops need BIOS bluetooth enabled

Rfkill blocked

rfkill unblock bluetooth

Pairs but won’t connect later

You skipped trust — repeat pairing with trust step above

Audio stuttering

Momentary Wi-Fi coexistence issue; try moving to 5 GHz Wi-Fi per Wi-Fi guide

Deeper logs: journalctl -b | grep -i blue.
