How can I tell if my laptop has Bluetooth?

Your kernel would have picked it up and loaded a module for it when you started Ubuntu. From the command line, gnome-terminal type this command:

If you get output simliar to the below then your laptop has bluetooth capability.

[ 2.933062] usb 1-1.4: Product: Broadcom Bluetooth Device 

That won’t work if it’s been a while since you booted the laptop. The kernel ring buffer has a limited size and keeps only the latest messages. Alternatively you can try journalctl -b .

sudo lsusb |grep Bluetooth 

Should give an output similar to:

Device 005: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode) 

If there is no bluetooth device, you’ll get no output for this command.

Please be aware that this will not work if your bluetooth device is using UART, not USB (if it is part of a SOC). In this case only dmesg will work.

Mine did not show up, but it works. Could it be connected with PCIe? It is a Qualcomm Atheros QCA9377.

on my Asus laptop i have a Bluetooth icon on the top right and

[ 3.757769] Bluetooth: Core ver 2.16 [ 3.757798] Bluetooth: HCI device and connection manager initialized [ 3.757802] Bluetooth: HCI socket layer initialized [ 3.757805] Bluetooth: L2CAP socket layer initialized [ 3.757814] Bluetooth: SCO socket layer initialized [ 3.767297] Bluetooth: Generic Bluetooth USB driver ver 0.6 [ 4.332846] Bluetooth: RFCOMM TTY layer initialized [ 4.332853] Bluetooth: RFCOMM socket layer initialized [ 4.332856] Bluetooth: RFCOMM ver 1.11 [ 4.340772] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 4.340776] Bluetooth: BNEP filters: protocol multicast 

but: sudo lsusb |grep Bluetooth Doesn’t return anything.

also check if you have a Hardware network (airplane mode) switch. This can disable bluetooth and make it not visible to Ubuntu

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.

3 Answers 3

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///info exists

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
