Bluez doesn't find any device (bluetooth not working)

[Astarot]

Hi there,
i have a problem, i was trying to configure bluetooth on my Dell Studio 1555 and it doesn't find any devices. First of all i was reading this article:
http://www.gentoo.org/doc/en/bluetooth-guide.xml (is this guide up to date at all ?)
i configured my kernel and recompiled it. This is my .config file:

I can't recall all the dependencies, but I had lot of trouble with bluez-gnome
and in the end just emerged blueman, which worked fine. There are a whole
lot of different "bluez" packages, all of which block each other, and seems best
to emerge the higher level package you want and let it sort out its own libraries.

I unemerged bluez-*** and emerged just bluez in version 4.60 i guess and still the same errors :/

I didn't change any USE flags and i didn't changed /etc/portage/package.use or something similar. Here is my output of emerge -av bluez:

These are the options I have enabled for bluetooth:

Now i have the same settings and nothing changed :/ I really don't know what's wrong, maybe it's not kernel ? Who knows, the result is that Bluetooth works on Ubuntu 9.10 but not on Gentoo on the same laptop. It's weird...

Well, blueman 1.10 and bluez 4.39-r2 worked for me with the kernel (30) settings:

CONFIG_BT
_L2CAP
_SCO
_RFCOMM
_RFCOMM_TTY
_HIDP
_HCIBTUSB
_HCIUART
_HCIUART_H4
_HCIUART_BCSP
_HCIUART_LL
_HCIVHCI

I have no idea what all that does; I basically enabled everything that looked
vaguely relevant, and it worked.

Good luck - Will

Plus, it's quite possible that bluez is simply broken for you. I know, that is something you don't like to hear, but I also had a lot of struggle with bluez not working.

It seems that the errors indicate that your bluetooth antenna (the one attached to your computer) is not found at all.

What you could do, (if it's usb) activate the proc USB filesystem and see if the driver is attached to the device.
What you could do, (if it's builtin) then you need to do lspci -v and see if a driver is associated with your bluetooth device.

If you provide a little more info like:

- What kind of device is it?
- Do you use udev?
- Are your bluetooth modules loaded?
- Is there anything new in dmesg after you start fiddling around with it?
- What kernelversion?
- What useflags did you activate for the related packages? (hal, dbus, blueman, bluez)
- What versions are you *now* using?

Then I could give you more specific help which could help narrow down the problem...

Don't worry, you'll get there .

Hi,

Can't find it now. But I don't think they have fixed it.
If you have a built in bluetooth the udev is not finding it.
You have to trigger the udev for it to find it.

Try to run

Could you please provide the output of (yes, please recompile it as a module ):

modinfo bt_usb

and

for i in `ls /sys/module/bt_usb/parameters/`; do echo ">>>"$i"<<<" ; cat /sys/module/bt_usb/parameters/$i ; done

Also, try starting bluetooth and watch dmesg for errors.

Also please post the output of:

lsusb -d 0a5c:4500 -v -v -v

[Astarot]

So i recompiled my kernel and marked everything as a module. I guess you meant not bt_usb but btusb So here we are:

[Rexilion]

Try:

[Astarot]

Nothing, simply nothing changed I guess i have to give up. That's impossible to run Bluetooth on Dell Studio 1555 on Gentoo. As you can see i tried everything. BTW what does hid2hci do ?

[Rexilion]

I have seen evidence on the net that it should work, as a final resort try switching kernel versions. I'm flat out of idea's here

I have no idea what hid2hci does, try running it

[MickKi]

Thanks for pointing to this thread Rexilion.

Same bluetooth device, similar laptop (XPS 16), same problem.

The hid2hci command switches between the native HCI bluetooth receiver mode and the HID USB emulation. It used to be in one of the configuration files, but was removed with the latest version of bluez (I am now trying out net-wireless/bluez-4.63 just in case).

I'm on kernel 2.6.32-gentoo-r8 and have enabled this much:

cat /usr/src/linux/.config | grep -i BT
CONFIG_BT=m
CONFIG_BT_L2CAP=m
CONFIG_BT_SCO=m
CONFIG_BT_RFCOMM=m
CONFIG_BT_RFCOMM_TTY=y
CONFIG_BT_BNEP=m
CONFIG_BT_BNEP_MC_FILTER=y
CONFIG_BT_BNEP_PROTO_FILTER=y
CONFIG_BT_HIDP=m
CONFIG_BT_HCIBTUSB=m
CONFIG_BT_HCIBTSDIO=m
# CONFIG_BT_HCIUART is not set
CONFIG_BT_HCIBCM203X=m
CONFIG_BT_HCIBPA10X=m
CONFIG_BT_HCIBFUSB=m
# CONFIG_BT_HCIDTL1 is not set
# CONFIG_BT_HCIBT3C is not set
# CONFIG_BT_HCIBLUECARD is not set
# CONFIG_BT_HCIBTUART is not set
# CONFIG_BT_HCIVHCI is not set
# CONFIG_BT_MRVL is not set
CONFIG_MAC_EMUMOUSEBTN=y
# CONFIG_INPUT_ATLAS_BTNS is not set
# CONFIG_VIDEO_BT848 is not set
# CONFIG_SND_BT87X is not set
# CONFIG_BTRFS_FS is not set

but my device will not be recognised:

$ hcitool inq
Inquiring ...
Inquiry failed.: No such device

Is there a point in enabling CONFIG_BT_HCIUART? I left it out because this is an embedded USB device rather than a dongle or similar. I have more details on the hardware here.

It doesn't work I'm afraid. I've recompiled bluez with the old-daemons, then:

[Rexilion]

Can you try a newer kernel? 2.6.33 or maybe even 2.6.34?
