Bluetooth problem - requires warm boot from windows to work

**dixoncx** · February 17th, 2012

OS: Ubuntu 11.10 x64
Device: Sony VAIO VPCEH15

My laptop has a hardware switch for wireless.

My problem is that,
If i boot to ubuntu, while wireless switch is turned OFF, then there is no way to use bluetooth..
If i turn ON wireless switch, then my wifi works but still bluetooth didn't works..

And i get "rfkill list" output as

Code:

0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: sony-wifi: Wireless LAN
    Soft blocked: no
    Hard blocked: no
2: sony-bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: no
3: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

The only way i left to turn on my bluetooth is,
first boot into windows, turn on wireless hardware switch, then warm boot to Ubutnu...

Is there any way to fix this problem ?

For me, I have to enable hci0 to use bluetooth since it is down by default.

So I get it to work with
sudo hciconfig hci0 up

Code:

$hciconfig 
hci0:	Type: BR/EDR  Bus: USB
	BD Address: 00:00:00:00:00:00  ACL MTU: 0:0  SCO MTU: 0:0
	DOWN 
	RX bytes:0 acl:0 sco:0 events:0 errors:0
	TX bytes:6 acl:0 sco:0 commands:2 errors:0

$ sudo hciconfig hci0 up

$ hciconfig 
hci0:	Type: BR/EDR  Bus: USB
	BD Address: 00:07:61:F9:0D:05  ACL MTU: 1017:8  SCO MTU: 64:0
	UP RUNNING PSCAN ISCAN

HI,

I'm having the same problem. My bluetooth works fine after if I first boot in Windows.

When my bluetooth doesn't work, I tried the command below, but I received a timeout message:

Code:

sudo hciconfig hci0 up

I've been trying some things. I've already installed a lot of softwares, tried to reinstall the bluez packages, but nothing worked.

If someone have a solution, please share.

No hope..

hciconfig gives "Connection timed out"

Code:

dixon@dixon-vaio:~$ sudo hciconfig 
hci0:    Type: BR/EDR  Bus: USB
    BD Address: 00:00:00:00:00:00  ACL MTU: 0:0  SCO MTU: 0:0
    DOWN 
    RX bytes:0 acl:0 sco:0 events:0 errors:0
    TX bytes:9 acl:0 sco:0 commands:3 errors:0

dixon@dixon-vaio:~$ sudo hciconfig hci0 up
Can't init device hci0: Connection timed out (110)

dixon@dixon-vaio:~$ sudo hciconfig hci0 reset
Can't init device hci0: Connection timed out (110)

Yeah, I can confirm the same problem on the same model of machine.

sudo hciconfig hci0 up's also giving me a connection time out...

First one of us to figure this one out, post here.
