bluetoothctl: list connected devices?

I'm trying to get a list of the connected BT devices in CLI on Kubuntu, but I can't seem to find how.

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 BT devices?

Solution 1:

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"

Solution 2:

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

Solution 3:

This may help: sudo bluetoothctl info MAC-ADDRESS-OF-DEVICE

Solution 4:

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.
