9360 Bluetooth Issue

Hi, Running Ubuntu on XPS 13 9360, having an issue where bluetooth is no longer available after suspend, and appears to not be on/enabled. Works fine after restart, but after suspend I lose all bluetooth connections. I can turn it off, but not back on. Also installed blueman and doesn't appear to have helped with this issue. Anyone else run into this and have any suggestions?

    I also have this issue, running Ubuntu 17.10

    Linux voyager 4.13.0-21-generic #24-Ubuntu SMP Mon Dec 18 17:29:16 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

    Is there any known solution to this?

    I have had this issue too, starting in November but seems OK at the moment (Fedora 27 14.4.8). I think the problem could be intermittent.

    Hi,

    I had a similar issue of Bluetooth disappearing some times after an unsuspend on Debian. After power on, it works, but if I suspend and unsuspend, Bluetooth disappears after a while.

    I'm not sure it's exactly what you experience, but it looks exactly like the symptoms of th "Bluetooth Stopped Working" thread, but this one has unfortunately been locked, so I can't seem to answer there.

    I also have the

    usb 1-3: USB disconnect, device number 2

    message in syslog.

    It doesn't look like a hardware issue, looks more like a driver/power management problem with the tlp package.

    I found that I could workaround this by blacklisting btusb from autosuspend in /etc/default/tlp (on Debian):

    # Bluetooth devices are excluded from USB autosuspend:
#   0=do not exclude, 1=exclude.
USB_BLACKLIST_BTUSB=1 # changed to one

    It looks like tlp is autosuspending USB Bluetooth when it shouldn't. This avoids that issue. Only issue I have is that sometimes, bluetooth doesn't reappear on unsuspend. Hibernate and unsuspend again fixes it.

    Hope this helps anyone with the issue.
