Again: Bluetooth adapter not detected [Solved]

Postby linuxfluesterer » Wed Jul 03, 2013 7:57

Hallo guys.
After installing last Sabayon Daily with KDE 4.10.4 and Kernel 3.9, I such got an upgrade with about 35 packages, including Kernel 3.9.7.
Since Kernel 3.8 and last KDE 4.10.2 my Bluetooth adapter was supported by Kernel and KDE, now I get the message in 'Bluetooth Adapters' that no adapter can be found, I should connect one'.
The following URL confirms that my Foxconn / Honhai bt with id 0489:e04e is part of the Kernel 3.8:
http://www.h-online.com/open/features/Kernel-Log-Coming-in-3-8-Part-3-Drivers-1802696.html?page=2
And this URL says, it belongs to Kernels 3.9 also:
http://cateee.net/lkddb/web-lkddb/BT_ATH3K.html
And when I start
Code: Select all
/etc/init.d/bluetooth start

then I receive
Code: Select all
* WARNING: bluetooth is already starting

So, I loaded btusb (again), without success.
Then I installed hwinfo and rfkill.
The result of hwinfo is:
Code: Select all
SL-K39-KDE410 auguste # hwinfo --bluetooth

        Soft blocked: no
        Hard blocked: no

And for hcitool dev, I receive
Code: Select all
hcitool dev
Devices:

yes ... none!
While I could use an SL 11 KDE out of the box for work with bluetooth, here I couldn't use my installing USB media to make bluetooth work, neither I can use my installed Sabayon KDE on hdd.
Though I've stroken my special FN key to activate/deactivate bluetooth, I can see only a different output in hwlist, when activated / not activated.
I have no idea. Is it possible there is a bug again, or something has changed in activating bluetooth procedure in KDE or else? Any help is appreciated.

Here my hardware:
Acer V3-571G Laptop
Intel Core i5-3210M
8 GByte Ram, 40 GByte hdd
NVidia GForce GT630M (switchable with integrated Intel graphics).
Bluetooth from Foxconn / Honhai
Sabayon Daily from 26/06/2013 with KDE 4.10.4 and Kernel 3.9.7.

Thank you very much, indeed.

Hi,

I'm also having this problem - can't say when it started as I used to run Sabayon with KDE 4.7 and bluetooth worked out of the box. I lost that install, through an unfortunate series of events, and have re-installed and am currently up to date as of this afternoon, (13 June 2013) running KDE 4.10.4 and kernel 3.9.7.

I have the same 'No Bluetooth adapters have been found.' and 'No adapters found. Please connect one.' messages in the system settings and no bluetooth task-bar icon either.

I was earlier running kde 4.10.3 and kernel 3.9.4 and bluetooth wasn't working hence the upgrade today...

I'll try to add some more detail later - just wanted to let you know you're not alone in this :/

Hallo Farmer-Bri.
Thank you for your support.
I've made a big jump from KDE 4.10.2 and Kernel 3.8.x to
KDE 4.10.4 and Kernel 3.9.7 in a new installation of Sabayon from SL Daily (26/06/2013)
due to insufficient internet conectivity, I haven't made any upgrades in between.
So, I have no idea, what is the reason of the lack in (KDE) Bluetooth.
I'd really know from some expert here,
do we have a Kernel bug or is it a KDE topic, because KDE says 'No adapters found. Please connect one'.
I'd really appreciate a reply by the Sabayon maintainers.
Thank you in advance.

Hallo guys (here especially Farmer-Bri).
I have made some tests with loading bluetooth in KDE itself and on command line (as root).
So, while I start KDE buetooth like bluedevil (which needs long time with any visable success,
other modules (like adapters) return with error: 'No bluetooth adaptor found. Pls connect one'.
So, no success at all.
Then I started
/etc/init.d/bluetooth start

which returns with the error
Code: Select all
Bluetooth already started

But in
Code: Select all
ps aux|grep blue

there is no line displayed with bluetooth.
I checked, that btusb is loaded and as module, bluetooth seems to be loaded also,
but in KDE, bluetooth is invisable because 'No adapter....'

So then I've made another test.
On root console, I simply typed
Code: Select all
bluetoothd start

and after this, bluetooth was (is) visable in KDE and my adapter is recognized and I can find other bluetooth devices
like I could in earlier versions.
But the solution is not working, when I put
Code: Select all
bluetoothd start

into an executable file (e.g. bluetooth.start) under
Code: Select all
/etc/local.d

where usually files are started while booting.
So, call bluetoothd manually as root may help for the moment.
But something in the booting sequence of Sabayon (KDE version) seems to be changed.
I will go on try, where I can start bluetoothd (as root) as late as possible.
(Maybe it works only AFTER KDE is already appeared?).

Maybe one of you has an idea. But what I guess is, that there is no Kernel bug.

Well done!

I'm sorry, I've been swamped with work - I've not been able to test anything up to now, but I can confirm that your workaround works for me too. Thank you so much.

So, I've just been having a play (rebooting my machine a lot) and it turns out that immediately after boot
Code: Select all
 /etc/init.d/bluetooth status
returned 'stopped' and when I started it.. it works :oops:

So, for me at least
Code: Select all
rc-update add bluetooth default
is the fix. :P

I'm feeling a bit sheepish as that was probably the first thing I should have tried, but I was a bit blinded by the fact it used to work out of the box - I'm also having quite a few other strange issues since rebuilding (an intermittently working built-in SD card reading, suspend only working 4 out of 5 times, X thrashing every other day, requiring a log-out) which is odd after the rock-solid KDE I used to have on the same computer...

Anyway - thanks again for your help linuxfluesterer, and I hope yours is the same, now at least I have one fewer problem :D

I have been having this issue since changing to systemd, every time I reboot no Bluetooth adapter detected, so this command has fixed it for me.

Code: Select all
systemctl enable bluetooth.service


Then reboot and it is now back to normal.

Yes, DeadlyWolf,
that was it finally.
I managed to enable local-d.servive to start then bluetoothd,
but I didn't think about to enable the bluetooth.service with systemctl directly.
Now I did enable it, deleted my bluetoothd.start script (no more necessary) and rebooted.
Works as wanted. Thank you for your hint.
I will mark the thread as [Solved] now.
