Connect to a Bluetooth device via Terminal

  • I'm using Mint 15 w/ Cinnamon.

    I bought a set of bluetooth speakers and I'm trying to connect to them via terminal. Via the GUI I can see them normally and I am connected to them. I want to make a small script so every time they are visible I would connect to them automatically.

    I am trying to scan them with:

    hcitool scan

    But I get

    Scanning...

    and after a few seconds the process dies.

    The same thing with hidd --search.

    If I run hciconfig scan I get:

    hci0:   Type: BR/EDR  Bus: USB
        BD Address: 40:2C:F4:78:E8:69  ACL MTU: 1021:8  SCO MTU: 64:1
        UP RUNNING PSCAN ISCAN 
        RX bytes:130700 acl:22 sco:0 events:18527 errors:0
        TX bytes:31875398 acl:36784 sco:0 commands:75 errors:0
    

    I suppose that is just saying my bluetooth address and that it is turned on.

    As I said already, via the normal User Interface, I can see the speakers and I am connected to them, but through terminal I get nothing.

    Actually it is quite funny that hcitool scan isn't finding anything since my speakers are connected and every time I run the command the sound from the speakers breaks for a couple of seconds.

    I managed to do so via bluez-tools:

    sudo apt-get install bluez-tools

    List of devices to get the MAC address of my device:

    bt-device -l

    and successfully connect to it:

    bt-audio -c 01:02:03:04:05:06


    Keep in mind that the bt-audio feature has been reimplemented probably some time in 2016, so bt-audio is likely no longer available as such.

    This is probably for an old version as there is no `bt-audio` command anymore

    On Linux Mint 17 (Cinnamon) I successfully used `bluez-test-audio connect MAC_ADDRESS` for an already paired audio device.

    I successfully used `bt-device -c mac_address` on Debian. 9.

    On Ubuntu 18.04, bt-audio is not available. Judging from bluez-audio issue #13, this has been the case for years. Running `bt-device -c ` doesn't help ("Error: GDBus.Error:org.bluez.Error.AlreadyExists: Already Exists") and I'm reluctant to go into hacks suggested under issue #13 because I have to do them on each machine, I expect they'll be deprecated easily etc. Can it really be that (after navigating to the right part of the settings GUI) it's a single click on GUI to redirect sound to a speaker, but that there's still no way to do it in a single, simple command from the CLI?
