[Surface Book 2] Bluetooth does not work at all [SOLVED] #535

Open mildmenace opened 5 years ago

mildmenace commented 5 years ago

Running Kali Bluetooth reports that it is turned off always. There doesn't appear to be any way to turn it on. When I toggle it to go on, it still says off.

I'm using the latest Kernel, 5.1.15

Hello,

I'm also seeing this issue on latest kernel. No bluetooth connectivity possible: 'no adapters'

looking around in dmesg I see this:

Trying the deprecated hciconfig: 

$ sudo hciconfig hci0 up
Can't init device hci0: Connection timed out (110)

running this also shows it's not being blocked:

$ sudo rfkill list
1: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

I'm running arch-linux-surface with 5.1.15 on a Surface Laptop

hciconfig returns an interface for me

$ hciconfig hci0: Type: Primary Bus: USB BD Address: F0:6E:0B:D2:0C:73 ACL MTU: 1021:7 SCO MTU: 240:3 DOWN RX bytes:647 acl:0 sco:0 events:38 errors:0 TX bytes:395 acl:0 sco:0 commands:36 errors:0

My devices are also not blocked:

$ sudo rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no 1: hci0: Bluetooth Soft blocked: no Hard blocked: no 2: phy1: Wireless LAN Soft blocked: no Hard blocked: no

What was the last Kernel version that worked for you?

33Fraise33 commented 5 years ago

I haven't tested bluetooth with any previous kernels so I am unsure if this is kernel version related or not

mildmenace commented 5 years ago

Which wifi drivers are you running?

I believe the wifi and bluetooth are on the same chip.

33Fraise33 commented 5 years ago

This is what I get for wifi driver:

I get the same, unfortunately

MrDanTheMan commented 5 years ago

Not sure if this is related but I also had an issue with Bluetooth not working until I installed bluez packages and manually started the Bluetooth service.

Arch: sudo pacman -S bluez bluez-utils sudo systemctl start bluetooth.service

mildmenace commented 5 years ago

That worked!

Thank you!
