[SOLVED] Dell XPS 13 9360 Late 2016 Bluetooth not working

Hello friends,

my internal bluetooth card doesn't power up although it should be usable following this post:
https://wiki.archlinux.org/index.php/De … _(4th_Gen)
Using an external card works, but this is somehow undesirable with such a fancy machine with KDE Plasma. Bluetooth was working under Windows 10 Home.
Kindly do the needful at the earliest!
smile  joking wink
Really appreciate any help !

Turns out it was related to Power Saving Software.
Namely TLP in this case.
Deactivating it solved it for me.

Cheers!

Re: [SOLVED] Dell XPS 13 9360 Late 2016 Bluetooth not working

Hi,
I find uninstalling TLP for this reason a bit overkill. I would rather blacklist the device from TLP configuration (as suggested in TLP FAQ).

> $ tlp-stat -u | grep -i btusb                                                                                                                     
Bus 001 Device 002 ID 0cf3:e300 control = on,   autosuspend_delay_ms =  2000 -- Qualcomm Atheros Communications  (btusb)

Add the device ID to USB blacklist from TLP:

> $ grep ^USB_BLACKLIST= /etc/default/tlp 
USB_BLACKLIST="0cf3:e300"

Reboot or apply the new setting:

> # tlp usb

Your bluetooth adapter should be working fine now.
