Thread: No bluetooth adapter found--what next?

    Question No bluetooth adapter found--what next?

    Greetings all

    I get a "No Bluetooth adapters have been found" message in KDE's Adapters--System Settings Module utility.

    I'm using Leap 15.1; bluetooth worked well under Leap 15 and 42.3.

    The machine is an Asus Zenbook UX330UA.

    Some diagnostics:

    Code:
    adam@linux-sv30:~> sudo systemctl status bluetooth
    [sudo] password for root: 
    ● bluetooth.service - Bluetooth service
       Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; enabled; vendor preset: disabled)
       Active: inactive (dead)
         Docs: man:bluetoothd(8)
    adam@linux-sv30:~>
    And:

    Code:
    adam@linux-sv30:~> sudo rfkill list               
    0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no
    adam@linux-sv30:~>
    Any help would be appreciated! I am stumped.

    And...yes, the problem is apparently with the WiFi-Bluetooth integrated chip.

    Thank you!

    Bluetooth chips should be shown by
    Code:
    lsusb
    But there is no Bluetooth chip.

    Is Bluetooth disabled by key? bios? windows?

    Please post as root:
    Code:
    journalctl -b | grep -Ei 'firm|blue'

    Bluetooth hasn't been turned off explicitly by me, and this machine doesn't have Windows on it. I have tried to turn it off and on again using the airplane mode key on the keyboard. WiFi works well, and that key works to turn it on and off. I can't find any setting in the BIOS to disable or enable network interfaces.

    Maybe the bluetooth component on the card has burned out?

    In any case here is the journalctl output:

    Also found this in the journalctl output--perhaps this indicates that the the bluetooth device isn't responding?

    Code:
    Aug 14 18:08:41 linux-sv30 kernel: usb usb1-port8: attempt power cycle
    Aug 14 18:08:42 linux-sv30 kernel: usb usb1-port8: unable to enumerate USB device
