I'm trying to get a list of connected Bluetooth devices via the command line on Kubuntu.
When I launch bluetoothctl, it defaults to the latest connected device, and I need to disconnect it to display the other one.
Is there a way to list the connected Bluetooth devices?

Here's a fish-shell one-liner (see below for bash)
bluetoothctl devices | cut -f2 -d' ' | while read uuid; bluetoothctl info $uuid; end|grep -e "Device\|Connected\|Name" bash one-liner:
bluetoothctl devices | cut -f2 -d' ' | while read uuid; do bluetoothctl info $uuid; done|grep -e "Device\|Connected\|Name" You can list paired devices with bluetoothctl paired-devices
From this list you can get info for each device with bluetoothctl info On the info you have the Connected status.
So loop on each devices grep for Connected: yes if so display the name:
bluetoothctl paired-devices | cut -f2 -d' '| while read -r uuid do info=`bluetoothctl info $uuid` if echo "$info" | grep -q "Connected: yes"; then echo "$info" | grep "Name" fi done This may help: sudo bluetoothctl info MAC-ADDRESS-OF-DEVICE
After running sudo bluetoothctl...
you can type paired-devices to see a list of paired devices
or list to see a list of currently connected controllers
you can also type info to see info about each device.
Each command here supports tab completion of MAC addresses.
I use this to display the currently connected device in my Swaybar:
bluetoothctl devices | cut -f2 -d' ' | while read uuid; do bluetoothctl info $uuid; done | grep -e "Name\|Connected: yes" | grep -B1 "yes" | head -n 1 | cut -d\ -f2- Breakdown:
bluetoothctl devices # List all devices cut -f2 -d' ' # Cut out the second column containing the MAC address while read uuid; do bluetoothctl info $uuid; done # For each MAC address call bluetoothctl info grep -e "Name\|Connected: yes" # Find all lines that have either name or Connected: yes grep -B1 "yes" # Find the line with yes and the line before that line head -n 1 # Return the last line cut -d\ -f2- # Return the second column and all other columns for the device name
