This pretty much looks like the adapter is just not automatically
enabled again after you restart the service. There is currently a udev
workaround rule in place to active a Bluetooth adapter directly at
login-screen time which wouldn't kick in here again. If there is no
general power state saver on desktop like urfkill you have to manually
enable bluetooth again.

#3 seems to be correct.

I added the following lines to the end of /etc/pulse/system.pa:

<BEGIN of snippet>
### Automatically load driver modules for Bluetooth hardware
.ifexists module-bluetooth-policy.so
load-module module-bluetooth-policy
.endif

.ifexists module-bluetooth-discover.so
load-module module-bluetooth-discover
.endif
<END of snippet>

(Notice: I stole the snippet above from this informative page:
https://github.com/ev3dev/ev3dev/issues/198 )

After executing pulseaudio -k all went smooth, bluetooth headphone seems
to work well for now. Hope it will stay that way.

Thank you for mentioning that you can manually add the device. My mouse
wasn't paired even using the hardware buttons. Going to the bluetooth
manager and selecting the mouse did work. I've added the udev rules in
the hope I won't need to do this manually each time. Thank you.

I have these errors in my dmesg with kernel 4.5.0 but not in 4.3.6 where
bluetooth works great. Kernel 4.4.x bluetooth behaves the same as 4.5.0
but I hadn't noticed if there are "failed to obtain..." messages.

When I boot in 4.3.6 bluetooth (bluez 5.35 and blueman, and a command
btattach... in /etc/rc.local) starts fine and I don't have to do much to
wake-up my bluetooth mouse and keyboard. In 4.4+ I have to manually
search for the devices, but I don't have to pair them again. I then
have to leave the blueman device manager running (minimized.) If
anything times out from inactivity, I have to search again to reconnect.

Asus T100-CHI Ubuntu 15.10-i386. Minimally patch kernel supports a lot
of the hardware of the T100, except sound, cameras, mic... Bluetooth
started working in kernel 4.3.3+ but regressed starting with
4.4-rc1->4.5.0.

I see a reference to a udev workaround, but that is a new area to me.
The example seems aimed at audio - how would I adapt that to
mouse/keyboard?

2 updates: 4.5.0-next-20160321: bluetooth self-starts like 4.3.6 used
to. I still need to open device manager to maintain connections, but I
no longer have to manually search for already paired devices.

The "failed to obtain..." messages are in journalctl not dmesg. Sorry
for any confusion that may have caused.

Same messages for me with 16.04 beta2, running with bluez 5.37-0ubuntu5
on 4.4.0-15-generic amd64 kernel. Running on Asus T300 CHI notepad with
bluetooth keyboard/touchpad docking unit. It pairs OK, but connection
comes up briefly and then drops again.

bluetoothctl log extract follows:

@Brian Burch - You might get more run time if you minimize the bt device
manager window instead of closing it after pairing (assuming that you
are using blueman device manager.) I find kernel 4.5 works a little bit
better with bluetooth. kernel 4.3.6 works like I'd expect with
bluetooth, if you don't need the newer kernel features.

We are describing is a kernel bug. I have the same bt connectivity
issues using Manjaro.

Following a suggestion from jbmacbrodie to minimise the blueman device
manager after pairing, I tried again. This time, I used the command-line
bluetoothctl program as sudo: the "paired-devices" command showed the
device was already paired from my previous session. "info [mac addr]"
showed it was not legacy-paired and not currently connected.

I flicked the switch on the docking unit (a bluetooth keyboard with
touchpad) so it would try to establish a connection. I then issued the
"connect [mac addr]", and bluetoothctl briefly showed it was connected
and the blue LED on the keyboard changed from blinking, to solid on,
then back to solid off in a matter of a few seconds.

syslog showed:

I also true using an old bluetooth usb dongle. I used it on the asus
T300, but that made no difference. I also tried it on my dell 1558
laptop, with 16.04 (64-bit) and 15.10 (32-bit with bluez 5.35). The
16.04 test was basically the same as on the asus. The 15.10 test was
different in detail, but still showed the docking station briefly
connecting, but disconnecting a second or so later.

All tests produced the "not enough handles" message from bluetoothd. Is
anyone successfully using bluetooth with these later ubuntu kernels?

On both of my systems I get the "not enough handles" messages but I got BT to work for both my use cases:
- using a BT mouse on a laptop
- streaming audio from my phone to my HTPC

That is useful to know, Laurent. I am pleased to know it works
somewhere!

I successfully paired my android phone to the T300, so this shows the
hardware and software is capable of recognising and using the "just
works" agent for a Simple Simple Pairing exchange (i.e. without
requiring user entry of a pin). I can't be sure, but I think this is
what happened when I paired the keyboard with windows 10.

Incidentally, I just tried connecting my wife's phone, which is newer
but almost identical. It paired but would not connect. I will run some
more btmon traces later today to look for significant differences.

I have a possible variant of this bug in 16.10 with a 4.4.0-22 (standard
kernel at time of writing), after a day or so of uptime i start to get
these messages. they seem to go away after a log out and login.

This is on a dell precision m3800 using plantronic back beat pro
headphones , this combination worked semi flawlessly for the duration of
15.10 and most of 15.04.

this seemed to help, now my headset auto connects on startup

I have this bug too, on 16.04. After booting bluetooth works fine, then
after suspend it's gone, and I get the 'not enough handles' errors. Only
rebooting works. The solution of amias does not work for me.

I messed around with this for ages with no luck on my Dell XPS 13 9350.
It seemed to even screw up the bluetooth when I rebooted back into
windows where I wasn't able to remove and re-pair my Microsoft Sculpt
Comfort Mouse.

Then through freak chance I plugged in an older microsoft usb mouse
(with the nano transceiver) and started using that. Not sure why but
later on I retried connecting my Sculpt bluetooth mouse and boom - it
worked straight away.

Was having the same trouble with bluetooth on my other laptop ASUS
Zenbook 305CA but did a full reinstall (Linux Mint 18) with only the usb
mouse plugged in. After install - tried to connect the bluetooth mouse
and it connected first time.

I'm aware that the usb mouse thing could be a total red herring but for
me it is the only thing I can think of out of everything I was trying
that actually made a difference - and on 2 different laptops so I'm
thinking there might be something there for other people to at least try
:/

I got this after accidentally starting the bluetooth service while playing audio via a2dp.
The hackaround from #4 worked for me.

I've enabled extended and debug logging (-E -d) in file:

was: ExecStart=/usr/lib/bluetooth/bluetoothd
now: ExecStart=/usr/lib/bluetooth/bluetoothd -E -d

Please find logs below, in attachments. Hope it will help to pin down
the problem.

Also experiencing this problem, on a pristine install of ubuntu 16.04.1 LTS
(4.4.0-45-generic #66-Ubuntu SMP, BlueZ version 5.37) onto a NUC6i5SYH.

I am doing nothing on the box, just setting it up.
The only packages I've installed are for sshd and bluez.

First run of the bluetooth service worked (well, discovery
worked, though I was unable to successfully connect to
the discovered lenovo edge keyboard).

After reboot, bluetooth service is failing same as others report:

On Lenovo w520, Ubuntu 16.04, kernel 4.4.0-57-generic, bluez 5.37-0ubuntu5, unity desktop.
Same error messages relating to "Not enough free handles to register service".
Resuming from suspend results in bluetooth icon in title bar grayed out, bluetooth switch is OFF, and bt mouse non-functional. Invoking the bluetooth settings from the icon shows bt switch ON. From the settings, turn bluetooth OFF, then ON again, then in the title bar icon, turn bluetooth ON also, then the mouse will connect. Happens 10-20% of the time resuming from suspend, greatly improved from kernel 4.4.0-32.

Hi all,

This bug affects me: Can't connect to my UE BOOM bluetooth speakers,
when I mess around with configuration and make it connect, the speaker
doesn't show up on the list of available speakers (Settings > Sound),
therefore, can't make them work.

16.04.1 LTS, kernel 4.4.0-59-generic.
#4 and #26 didn't make any change. Net thing to try is downgrade to 4.3.6 if that's possible.
logs:

@aromo Similar issue, couldn't connect UE Boom speaker was just getting
'Unable to register GATT service with handle 0x0001'. Found it strange
that even when the speaker was powered down bluetoothd kept trying to
connect (and disconnect seconds later)

What I found was, UE Boom speakers can be powered on remotely using the
mobile application - which is done through Bluetooth LE. This is why the
speaker was connected even when powered-down because of it was connected
via LE. I could be wrong but I believe the GATT service manages the
messages from LE devices - So I tried disabling Bluetooth Low Energy on
the laptop bluetooth adaptor through this command:

sudo btmgmt le off

Unpaired the speaker, restarted the laptop and afterwards I had no more
"Unable to Register GATT" or "Device is already marked connected
messages" and I was able to connect the speaker through Audio Sink.
Haven't had any issues with it since (except for having to run a2dp.py -
but that is a separate issue)

Perhaps you could try disabling le and see if it works for you too?

Thanks for your suggestion; happy to try any solution suggestions.

When entering the command I get:

Set Low Energy for hci0 failed with status 0x0a (Busy)

Tried finding more information about this message but couldn't find anything which seemed relevant.
Any suggestions?

(BTW: just to be clear: still no working connection with the bluetooth
device.)

Just to -perhaps- add to any confusion: when I submit the command "sudo btmgmt le off" in terminal, I expected the command to simply do its thing (switch off le) and then return cli to the "waiting for input" status. Well, it doesn't: when I submit the command and enter my password and press <enter> nothing happens. To get back to "input mode" in terminal I have to press CTRL-C.
(I hope this description makes any sense.)

Is this normal behaviour?

I just tried running the command to turn off le when connected to a
device and I got the same message 'status 0x0a (Busy)' so perhaps you
are already connected to something.

My suggestion is to unpair all devices (if you have any paired) and running the command:
rfkill block bluetooth

That command soft blocks the bluetooth adapter - so it won't be able to
attempt any connections. After is it blocked try running the le commannd
again (sudo btmgmt le off)

Then unblock the bluetooth adapter by: rfkill unblock bluetooth.

I was receiving many of the same errors in my logs, and after about 15+
fixes I tried, this was what ended up working. My main issue wasn't
really connecting the headset, it was keeping it connected for more than
a couple seconds and being able to play a2dp. Hopefully this works for
some of you.

Go into bluetoothctl and set your device to trust

# bluetoothctl
# devices
Device XX:XX:XX:XX:XX:XX

Just to note that I had similar problems that were solved by cyano's suggestion in #32
(Using Ubuntu 16.04 LTS with a cheap CSR8510 chip USB bluetooth dongle and Clarity bluetooth speaker.)

sudo btmgmt le off

Then using the standard Bluetooth Settings app deleted the current
connection from the list of devices and remade the connection. This
resolved the problem.

However, in order to get the speaker to appear in the list of output
devices in Sound Settings I find I always have to switch the bluetooth
connection to the Clarity speaker on, then off, then on again at the
start of a session (using the Bluetooth notification area drop-down).
After that, it's fine for the remainder of the session.

Encountered today on Ubuntu 16.04 quite surprisingly, as bluetooth is
usually problematic (with https://bugs.launchpad.net/bugs/1577197 ), but
not broken.

Disabling LE did not resolve issue. I'm expecting (hoping) rebooting
will, since it worked before.

That sounds like an excellent workaround. It's probably not a fix
though. A fix would involve finding out why the config has confused
bluez.

Actually this sounds like an "old" bug that was fixed after 16.04 since newer releases aren't being reported. If we could figure out what fixed it then we could backport that fix to 16.04. You can search the code here:

Well that didn't work. I backported
f558fca8d64e3795b0654a90d343af1dd1d8b33c to xenial and found it only
fixed "Failed to obtain handles for "Service Changed" characteristic"
but not the errors immediately after it: "Not enough free handles to
register service".

Sounds like that commit is not related to this bug. Also that commit
didn't get released till Bluez 5.44 so it was solving a problem that
existed in all Ubuntu releases (till artful got 5.45 last week).

If this bug however was fixed in 16.10 or 17.04 then the fix must have
been something different.

Sorry for the confusion (which actually seems to have started in comment
#1 :).

This bug is not about "Not enough free handles to register service".

This bug (as first reported by TJ) is about "Failed to start discovery:
org.bluez.Error.NotReady" which happens after restarting the daemon. And
actually, it seems that's not a bug. "scan on" fails because the
controller (your bluetooth hardware) is turned off by default. All you
need to do is type "power on" before "scan on".

If anyone would like to log a separate bug for "Not enough free handles
to register service" then please feel free :)

** Description changed:

On 15:10 after the bluetooth service has been stopped and restarted it
is not possible to scan or connect to devices:

My laptop runs ubuntu 16.04. Linux: 4.4.0-93-generic
I tried to debug this issue by compiling bluetoothd from source code.
Surprisingly, this issue is fixed after executing newly compiled bluetoothd instead of /usr/lib/bluetooth/bluetoothd.
Steps to build and run newly compiled bluetoothd is listed below.

sudo systemctl disable bluetooth.service
sudo systemctl stop bluetooth.service
* make sure bluetoothd started by systemd is stopped.
sudo systemctl status bluetooth.service

* build bluetoothd
mkdir test
cd test/
apt-get source bluez
cd bluez-5.37/
sudo apt-get install libglib2.0-dev
sudo apt-get install libdbus-1-dev
sudo apt-get install libudev-dev
sudo apt-get install libical-dev
sudo apt-get install lib64readline-dev
sudo apt-get install libreadline-dev
./configure
make
cd src/
ls
sudo ./bluetoothd -n
bluetooth may work now.

The drawback is that you have to start bluetoothd manually after reboot.
Good luck.

Same issue here with Mint 18.2 Cinnamon and HID Logitech Mouse M535.
No matter which Kernel i used (from 4.8-x to 4.13.0-17) the same issue occured again.


I finally got it working again by issuing the command

sudo bluetoothctl

power off
power on
quit

After that, wWhile running bluewho besides blueman, I finally managed to pair the frickin thing again.

Hope it lasts.

This bug effects 128 people and closing it because you don't like the
title feels wrong. Two Ask Ubuntu questions point to this Lanuchpad bug
report in the hopes it will be solved:

https://askubuntu.com/questions/757396/bluetooth-how-to-solve-not-
enough-free-handles-to-register-service-error

and

https://askubuntu.com/questions/773629/16-04-bluetooth-error-not-enough-
free-handles-to-register-service

A Debian bug report suggests a solution by using -E (experimental)
parameter on the systemd service exec doesn't work for Ubuntu 16.04,
Kernel 4.14.4: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=813949

When a hundred reported people are effected by "Not enough free handles
to register service" and you don't want to look at it because the bug
title isn't right, why not simply change the title?

Something else to consider are the thousands of people effected by
bluetooth connection problems, re-pairing, etc. What if the root of
their problems was this bug that you don't want to look at?

Yes I understand you and most people are asking for a resolution to "Not
enough free handles to register service". However it is better for a
bug's resolution if we focus on the problem that the original reporter
was trying to describe. And that's a very different, unrelated problem.

We certainly could rename this bug and commandeer it to be about "Not
enough free handles to register service". But there's probably no need
for that.

If anyone would like a resolution to "Not enough free handles to
register service" then please start by opening a bug for it here:
https://bugs.launchpad.net/ubuntu/+source/bluez/+filebug

Very simple and very clean.

The original bug title was '15:10: bluetoothd reports "Not enough
handles to register service" at start', and the original bug description
described both the "Not enough free handles to register service" problem
and the "Failed to start discovery" problem[1]. Between #47 and #48, the
title and description were changed to focus on the "Failed to start
discovery" problem.

It seems to me that most of the people in the thread are focused on the
"Not enough free handles to register service", and aside from the close
message in #48, the only mention of the "Failed to start discovery"
problem was in the original description. Perhaps it would be useful to
split the "Failed to start discovery" problem off into its own bug and
keep this bug focused on "Not enough free handles to register service"?
That way the history and relevant log files are all kept in one place,
subscribers won't have to subscribe to another bug, and links pointing
to this bug for the "Not enough free handles to register service"
problem won't need to be updated.

Yes the bug title changed but the problem the original reporter was
describing in the bug description did not. The original description and
the current description both say:

"On 15:10 after the bluetooth service has been stopped and restarted
it is not possible to scan or connect to devices:"

Thus the original bug title was just a mistake, which has been
corrected.

It is inappropriate to commandeer and change the direction of a bug from
the intent of the original reporter because at any stage they do have
the right to change it back, or to proclaim that some eventual fix does
or does not resolve the original problem.

There are only 28 people, not 128, really subscribed to this bug. I'm
sure one of you could just follow this link and open a new bug:
https://bugs.launchpad.net/ubuntu/+source/bluez/+filebug

It is actually pretty common for people to say "hey that bug you closed
doesn't fix the problem for me". However the bug should still remain
closed unless those people happen to be the original reporter. So in
that case, yes, if TJ was willing to change the description of this bug
to be about the problem you describe rather than the original problem
s/he reported then that's possibly OK.

first thing first: bluetooth device can be paired with command line.

I have the same error on my eOS/ubuntu 16.04, "bluetoothd[17440]: Not
enough free handles to register service", and have tried many many
options, have desprated for a year.

and today I've success connected my bluetooth headset via command line.
following struction provided by "jeremy31" here at #4 :
https://ubuntuforums.org/showthread.php?t=2338474

ps. at first the sound was config to use hsf/hfp be default, which will
gave you horrible sound, change to A2DP Slink in pulseAudio will get
much better sound.

ps 2. after pair device via command line, the headset is show in system
setting/bluetooth list. but new device can only be added via command
line.

hope this can help someone.
