Bluetooth no longer working after upgrade to Feisty

Bug #110375 reported by useResa on 2007-04-26
Affects Status Importance Assigned to Milestone
gnome-bluetooth (Ubuntu)

Bug Description

Binary package hint: gnome-bluetooth

Since my upgrade to Feisty my mobile phone (SAMSUNG SGH-D900) can no longer connect to my laptop (DELL Latitude D620). It used to work flawlessly in Edgy.
What I used to do is go to Applications --> Accessories --> Bluetooth File Sharing, switch on bluetooth on my phone and I could transfer files between my laptop and my phone. Since the upgrade my phone cannot find my laptop anymore.

If I use hcitool (either scan or dev) no devices are found. If I issue the command "sudo hciconfig hci0 reset" and then try the command hcitool (both scan and dev) the devices are found.
However, transfer of files is impossible because the phone does not detect my laptop.

I have also made a thread about this, which can be found here:

If more information is required, please let me know

Similar Problem, in Dapper and Edgy my bluetooth keyboard and mouse auto-connected. Right after feisty update I have to fight and get the keyboard/mouse working so I can login. When I try to run hcitool scan nothing comes up. No such devices, and I can't get the devices to reset. I am using the Logitech Dinovo Desktop Laser Keyboard, Mouse and Mediapad. With the Logitech Mini Bluetooth receiver plugged into USB.

In further search on how to get bluetooth working again, today I installed the package obexpushd.
This results in the fact that I no longer have to issue the command "sudo hciconfig hci0 reset", but that my phone is immediately detected when using "hcitool scan".

However, I still can not transfer files from my phone to my laptop.

Did you try installing the other obex packages? Perhaps that would help?

I tried that and no success. Unfortunately.
Still don't understand how the upgrade could have stopped it from working.
Is a different package used?

Andrew Fenn (andrewfenn) wrote :

I have no idea either. I just upgraded to feisty and my Bluetooth just completely vanished.

Additional comment:
Initially hcitool scan gave the following result
Device is not available: No such device
And hcitool gave the result

After issuing the command sudo hciconfig hci0 reset, the results altered.
For hcitool scan into:

And for hcitool dev into:

The attachment shows the result AFTER the command sudo hciconfig hci0 reset.

My Bluetooth is not coming up in "/dev/rfcomm0" though as it did before with the same configuration so I can not connect to my phone

On a fresh new install of Unbuntu 7.04 (on desktop machine, not laptop), I had to install all bluetooth packages I found in Synaptic (weren't there by default like in Edgy), then reboot and it works (well except for mounting my Nokia FS via Symbian).

Before I reboot it couldn't pair.

Exact problem, but in kubuntu 7.04

Using generic usb bluetooth module, worked fine on dapper and edgy on Dell dimension.
SDP errors pop up on book until command:

# sudo hciconfig hci0 reset


# hcitool scan

can find devices, but cannot connect with them. Other devices cannot discover computer. Trial-and-error test of addresses (to find undiscoverable bluetooth devices) could not be attempted. Has anyone tried?

I think I have a similar problem. I have a Samsung D800, and I cannot send files from my phone to my hp dv5000 laptop (Feisty) which has bluetooth built-in.

hcitool dev:

        hci0 00:16:41:7D:59:99

hcitool scan:

Scanning ...
        00:17:D5:37:EB:56 D800

So it seems the computer can detect both its bluetooth and my phone. But when I try to send a file from my phone, the Samsung is unable to detect my computer.

Is there any solution to this?

Matt Wallace (mmw-old) wrote :

This is also not working on any of my computers running 7.04 with generic USB dongles. It was working fine until the upgrade to Feisty.

The main issue I have is that hcitool can detect the phone after a scan, however when "hcitool cc" is issued I do not have enough time to type "hcitool auth". The BT icon on my phone changes for about 0.5 of a second to "connection active" ( the usual "B<" plus "<>") and then looses the connection again.

I have tried restarting, reinstalling and resetting the pairings (deleted everything in /var/lib/bluetooth), the hcid.conf, dbus and rfcomm.conf to no avail.

Does anyone have either further ideas for me to try or a patch for this? I have discovered that this seems to affect other distros, so I am wondering if this is an up-stream issue.



Andrew Fenn (andrewfenn) wrote :

With regards to the issue of you not having enough time to auth...

I believe that is because there is "no route to host". Which is the error I am getting when I tired connecting to the phone in various ways.

Matt Wallace (mmw-old) wrote :


Which tools do you get this issue with? I seem to be able to do an OBEX-Push to the phone without it being paired (although I'm not at my PC right now to check this!) it just won't pair.


I have bought a Dell Latitude D800 and when it had Windows, the Bluetooth was working. When I removed Windows and installed Ubuntu 7.04 Feisty Fawn, the Bluetooth stopped working. I checked out at my computer's BIOS and I found out that it was saying "Onboard bluetooth: Not installed". I have installed every single package I found in the repositories related to Bluetooth, but with no success.

I don't know if that helps, but some guys claimed to have their Bluetooth disabled right after enabling the Wireless, or installing some drivers for the Wireless. I don't know how much truth there is in that, but it may be connected with bug #122419. Anyway, I don't remember having Bluetooth since I installed Ubuntu 7.04 Feisty Fawn.

At one point, for no reason at all, the phone stops detecting my laptop. The laptop can detect the phone and send files, but the phone CANNOT detect the laptop.

Do: hciconfig -a
Look for "UP RUNNING" at the 3rd line
It shows exactly that on my feisty.

Do: sudo hciconfig hci0 piscan
Then it shows "UP RUNNING PSCAN ISCAN" and that's when the phone can see the computer again.

Hope it's relevant.

However ... my phone still does NOT detect my laptop.
So for me this was no solution.

I was having the same problem with a fresh feisty install on my Dell Inspiron 6400. Seemed I didn't have all the necessary bluetooth packages installed. I already had gnome-bluetooth and bluez-utils. After apt-get install bluetooth bluez-gnome, I was able to set the visibility of the notebook from the system preferences bluetooth config and from my phone I was finally able to pair with the computer. From there everything seemed fine and I used wammu to sync my contacts and transfer old contacts from my previous phone. Hope this helps a bit.

useResa (rdrijsen) wrote :

I have all four packages that you indicate already installed (checked with dpkg -s <package name>).
I indeed have heard that people were able to set their visibility through System --> Preferences --> Bluetooth Preferences.
However, see also attachment, I can only set the visibility of the icon not of my laptop.

I have tried a reinstall of the two packages that you mentioned (bluetooth and bluez-gnome), followed by a restart of my X session but that did not make a difference.

Robin, you should see if you, by mistake, disabled the Bluetooth of your computer, with a key combination.

balopat (patobalint) wrote :

Gromit, Andrew to the "timing issue":

The bluez packages and all the BT related packages I found are installed.

- hcitool scan recognizes the phone
- hcitool cc connects to the phone for about half a second (I can see ot my phone)
- if I call hcitool auth during the active connection, it throws an Authentication failed: Input/Output error (sg like that).
- if I call it _after_ the half second it throws: Not connected.

I can use the Obex File Transfer as well, without pairing.
I cannot use the Obex Bluetooth Chat: at the point of authentication, my phone asks for the pairing key but ubuntu doesn't show the dialog to enter it. I tried the default key 1234, what I found in the hciconfig but it was useless too.

I'm looking forward to the solution of this problem, or any workaround.

I see this bug with a Dell Latitude D610 laptop, and a Sony Ericsson K600i phone:
 - hcitool scan shows the phone
 - hcitool cc registers the laptop with the phone
 - hcitool auth reports back

So it's a bug confirmation in case that's needed.

I've got a similar bluetooth problem. I have a logitech bluetooth keyboard and mouse that worked great with 6.04, but when I boot 7.04 and start moving my mouse it will go dead. The little LCD screen on my keyboard says (no connection). I crawl behind the computer and disconnect the little square receiver and plug it back in, and it all starts working again and I can log in and start using it. It did the same thing when I booted from the live CD, but I figure an update would cure it. Unfortunately updates haven't addressed it, and I've got my computer set on dual boot, and as much as I want my wife to get comfortable with ubuntu, she's not savvy enough to do that every time the computer boots up, so for now I tell her to scroll down in GRUB and use XP until I can figure it out. Anyone know of a setting that is off by default that wasn't off by default in the last 2 releases.

Perhaps I should start a new bug...?

This issue has NOT been resolved with the recent Gutsy upgrade. In fact, it seems to be worse.

I no longer am able to use my DiNovo keyboard. The mouse still works but the same issue seems to occur.

Once the login screen is displayed, Bluetooth stops working and does not come back until I unplug the dongle and plug it in to a new port.

:( This is quite a bit frustrating. It was nice how well Ubuntu supported my hardware but it seems to have taken a step back with the latest release (I mean, come on, LOSE support for my KEYBOARD?!).

This might be a good suggestion ... the bluetooth issue is also not resolved for me.

In that case all that have posted here can provide their info in the new bug as well.

So, it still seems that in Gutsy and Linux 2.6.22 this has not been fixed.

I can confirm I still have the problem on Gutsy, but it is not a kernel
issue; when running Fedora 8 bluetooth works flawlessly.

is there anyone working on this? Considering how long gutsy is now "on the market" it's a shame that this still is an issue!

Many people who dual-boot Ubuntu and Windows, say that if you download and install the drivers from the DELL website, in Windows, bluetooth starts working in Ubuntu, as well. Obviously, the Windows drivers enable the bluetooth from BIOS, so, Ubuntu can recognize the onboard bluetooth. I think the solution is to make the Ubuntu drivers able to enable the onboard bluetooth in BIOS.

This certainly isn't true for me; bluetooth has always worked in windows with the generic windows xp drivers. However, there is good news - using the liveCD version of Kubuntu 8.04 Beta (KDE4 version). I'll be migrating to 8.04 soon.

I installed Gutsy x64 on my Macbook Pro 3.1 from the Live CD this week, then decided to do a reinstall from the Alt CD to take advantage of the LUKS drive encryption. Bluetooth worked like a charm under the Live CD, but I'm getting nothing after reinstalling. hcitool scan yields "no such device." It's a built-in bluetooth module. Bluetooth works fine in OS X. This is my first post here, so please let me know if there's more info needed.

I have a Bluetooth USB dongle and the bluetooth module was loaded, however no bluetooth icon was shown in the notification area.

dmesg | less showed that the module was loaded correctly and lsusb showed that it found and correctly identified my dongle.

I had to install bluez-util before it started working for me.

So I think that either bluez-util needs to be installed always, or there is a bug/issue here.
