[SOLVED] Bluetooth Issues on a Supported Chip

So I have a new Dell XPS 13 9350 with an Intel 8260 WiFi/Bluetooth wireless card. On Arch, WiFi works out of the box but Bluetooth has been a bit of a pain. I run Gnome and, after booting, Bluetooth shows up but is "Visible as 'Bastien's Computer'" and simply doesn't find any devices. Output of

dmesg | grep Bluetooth

is

[ 6096.893070] Bluetooth: hci0: Bootloader revision 0.0 build 2 week 52 2014
[ 6096.898109] Bluetooth: hci0: Device revision is 5
[ 6096.898118] Bluetooth: hci0: Secure boot is enabled
[ 6096.898122] Bluetooth: hci0: OTP lock is enabled
[ 6096.898126] Bluetooth: hci0: API lock is enabled
[ 6096.898138] Bluetooth: hci0: Debug lock is disabled
[ 6096.898144] Bluetooth: hci0: Minimum firmware build 1 week 10 2014
[ 6096.898154] Bluetooth: hci0: Found device firmware: intel/ibt-11-5.sfi
[ 6097.007850] Bluetooth: hci0: Failed to send firmware data (-38)

If I run

modprobe -r btusb
modprobe btus

as root then Bluetooth works and becomes "Visible as 'ed-laptop'" in gnome Bluetooth right up until I reboot or put the laptop to sleep. The output of dmesg is then as follows

[ 7390.361794] Bluetooth: hci0: Bootloader revision 0.0 build 2 week 52 2014
[ 7390.366835] Bluetooth: hci0: Device revision is 5
[ 7390.366843] Bluetooth: hci0: Secure boot is enabled
[ 7390.366848] Bluetooth: hci0: OTP lock is enabled
[ 7390.366852] Bluetooth: hci0: API lock is enabled
[ 7390.366856] Bluetooth: hci0: Debug lock is disabled
[ 7390.366861] Bluetooth: hci0: Minimum firmware build 1 week 10 2014
[ 7390.367221] Bluetooth: hci0: Found device firmware: intel/ibt-11-5.sfi

[ 7392.316870] Bluetooth: hci0: Device booted in 11684 usecs
[ 7392.316947] Bluetooth: hci0: Found Intel DDC parameters: intel/ibt-11-5.ddc
[ 7392.318873] Bluetooth: hci0: Applying Intel DDC parameters completed
[ 7392.319963] Bluetooth: hci0: Setting Intel event mask failed (-16)

I've tried blacklisting btusb and then adding it to /etc/rc.local and enabling rc.local to run at start with a systemd service but that produced the same results. I've disabled any power saving stuff (laptop-mode and powertop) but the problem still remains. Annoyingly the bluetooth works perfectly on a fresh install and also works perfectly under a Ubuntu live disk, so it's not a hardware issue and almost certainly something i've installed. I've tried everything I can think of - BIOS updates, updating to a testing kernel and updating kernel-firmware to testing too; nothing works.
Any help would be really appreciated. Thanks!

Re: [SOLVED] Bluetooth Issues on a Supported Chip

Solved it! Turns out it was something to do with laptop-mode tools. Disabling the runtime-pm module solved it.

Re: [SOLVED] Bluetooth Issues on a Supported Chip

Hi,
I have the same identical configuration: XPS13 with Intel 8260.
But...the wifi works under iwlwifi-8000c-16.ucode and bluetooth isn't recognized.
In the dmesg the bluetooth there aren't.
How I can use it?

Re: [SOLVED] Bluetooth Issues on a Supported Chip

Have you followed the instructions here? bluez and bluez-utils need to be installed and the btusb kernel module loaded.

pacman -S bluez bluez-utils
modprobe btusb
systemctl enable bluetooth
systemctl start bluetooth

as root.

Does

dmesg | grep Bluetooth

Bluetooth output anything? Notice the capital B on Bluetooth - that's important. Post any error messages that you get and I'll do my best to help you.

No, I don't use the bluez e btusb.....because I found here  https://wiki.archlinux.org/index.php/De … %282016%29 this string:
" Note: Intel WiFi users: If your WiFi card supports Bluetooth, then the BT interface should be available out-of-the-box, as the required firmware is included in linux-firmware."

I must install your package?

I'm no expert, but from what I understand the firmware is in the kernel but the utility to actually use the firmware is not. Someone more experienced feel free to correct me, but I understand bluez to be the utility that utilises the firmware to allow Bluetooth connections to be made, in a similar way to how wifi-menu and NetworkManager allow WiFi connections to be made.

Re: [SOLVED] Bluetooth Issues on a Supported Chip

Hi edrose

I have the same laptop, and the same issue. Could you elaborate a bit more on the solution? I do not have laptop-mode installed.

Thanks!

EDIT: After some more digging, it turns out one really has to enable the bluetooth.service in systemd. Sorry for the noise. After that, everything works well.
