    Bluetooth Not Working

    I have Ubuntu 18.04.3 LTS installed on an HP 250 G7 laptop, however the Bluetooth won't switch on.

    No Bluetooth Found
    Plug in a dongle to use Bluetooth.

    How can I solve this issue please?

    Check that it's not disabled in the BIOS and that you did not inadvertently turn if off via an Fn-key combination.

    Re: Bluetooth Not Working

    Does the laptop have a physical BT/Wifi switch?

    It's enabled from the BIOS.

    "Does the laptop have a physical BT/Wifi switch?"
    No, it's doesn't.

    Re: Bluetooth Not Working

    According to http://h10032.www1.hp.com/ctg/Manual/c06207912 it has an "airplane mode" key combination. Maybe that's the culprit?

    In Ubuntu, open a terminal and enter "sudo lshw". Do you see a similar entry to this one? (This is a Lenovo so your results will likely be different.)

    No, it's doesn't.
    Can you get to a terminal and run "sudo rfkill list", and post the output?

    The Airplane Mode is F12, however to no avail.


    And, this is the output after running the command sudo rfkill list

    Code:
    root@MLT-0093:~# sudo rfkill list
    0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no

    Re: Bluetooth Not Working

    Doesn't look like you have bluetooth at all, or the hardware is dead or turned off. Not showing up under a hw list, or on rfkill. Should at least see the device as blocked even if its not working. Try this in a terminal and reboot.
    Code:
    sudo echo 'AutoEnable=true' >/etc/bluetooth/main.conf && /etc/init.d/bluetooth restart

    Does your usb dongle work bluetooth? Also try running "dmesg | egrep -i 'blue|firm|net'" and see what you get, or redir the command into a file and look in it. Maybe device firmware file isnt loading, especially if you have broadcomm hardware. Did you consider loading version 19 instead of 18.04? Might fix things.

    I ran the command dmesg | egrep -i 'blue|firm|net , but nothing happened.


    Code:
    root@MLT-0093:~# sudo echo 'AutoEnable=true' >/etc/bluetooth/main.conf && /etc/init.d/bluetooth restart
    [ ok ] Restarting bluetooth (via systemctl): bluetooth.service
    Still didn't work. I would like to get it working on 18.04, that's why I didn't try it on version 19.

    Ok and I asked if your blutooth dongle worked so does it? Because everything you posted says your bluetooth hardware is dead or turned off since none of these commands are finding anything at all bluetooth related. Going to 19 may make things work since itll have updated drivers that'd be the first thing I try.
