Retrieve paired Bluetooth devices from console
Is there any way to retrieve all paired bluetooth devices («Friendly name» and MAC-Adress) from the console? Is there any universal solution for any Linux distribution? In case there isn’t: I’m using an Ubuntu derivative. I already tried some stuff with hcitool , but nothing worked so far.

Late to the party, I tried listing as suggested by @panmari and @MarkCh but I was getting some unknown mac addresses (on a C.H.I.P with Debian), so I used the following command:
It will return both friendly name and Mac of all paired devices.
I found a solution myself. In Linux, the friendly names with their according mac adresses are saved in the file:
It should be easy enough to read it out with a shell script or the programming language of your choice.
This directory does not exist on Ubuntu 17, nor the file names , but /var/lib/bluetooth/
Install bluez-utils , run bluetoothctl paired-devices . See bluetoothctl —help for more useful commands.
I am using Raspian on Raspberry Pi 4 and connected my Bluetooth keyboard via the GUI. After setting boot mode to CLI it did not work anymore. bluez-tools (now bluez) was already installed. After starting bluetoothctl I saw with the command paired-devices , that no keyboard was connected. With scan on I was able to find out the device address and pair it with pair , trust it with trust and connect it with connect
bluetoothctl: list connected 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
Welcome to Super User! Would you mind explaining how that would help the person who asked the question?
I see my headphones listed when i run bluetoothctl paired-devices — but when I run bluetoothctl info I still get the error Missing device address argument .
@CarlWalsh, the error tells you exactly what you’re missing: bluetoothctl info gives information about a single device, thus you need to tell it the MAC address of the device you want to get information about.
As of bluez/bluetoothctl 5.65 ( bluetoothctl —version ), we can use bluetoothctl devices Connected (Capitalized C) to list connected bluetooth devices. For example:
$ bluetoothctl devices Connected Device AA:BB:CC:DD:EE:FF MY-DEVICE-NAME
If you care about paired devices, use bluetoothctl devices Paired for bluez/bluetoothctl version >= 5.65, or bluetoothctl paired-devices for bluez/bluetoothctl < 5.65.
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-
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
