Pairing: passcode dialogue disappears in <1 second

[Paul Sladen]

Binary package hint: bluez-utils

The pairing dialogues to allow entering a pin and initiate pairing disappear too fast.

If I do the following:

  sudo hcitool cc 00:19:DB:0A:xx:yy && sudo hcitool auth 00:19:DB:0A:xx:yy

a notifier window will pop up for ~1 second and then disappear.

If I click on the notifier window fastest, the main passcode/pincode entry dialogue will disappear. This also disappears within 1second.

The key seems to be that it is necessary to 'auth', click and 'pincode' within 1 second of a connection being made. This should actually wait until the user is able to and none of the dialogue boxes should cut-off early and disappear without warning.

Forum post discussing the same thing, with screenshots:

Which version of ubuntu are you using and which version of bluez-* packages.
I remember seeing this bug back in previous version than hardy, it seems this is fixed now.

[Baptiste Mille-Mathias (bmillemathias)]

Paul,

could you answer?

[Baptiste Mille-Mathias (bmillemathias)]

No answer so far, closing as incomplete

[John Pye (jdpipe)]

I am also seeing this problem. The connection appears to drop even if I don't attempt the 'hcitool auth' command. Below is the output from 'hcidump -X -V'. I am using Ubuntu Hardy, all up to date and current with standard repositories. My headset is Nokia BH-501.

Reopened with new info

[John Pye (jdpipe)]

I should add that the Nokia BH-501 headset apparently supports Bluetooth 1.2 but not Bluetooth 2.0, and also that when pairing the headset with my Nokia phone, there appears not to be any such timeout issue; the pairing works fine.

Cheers
JP

[John Pye (jdpipe)]

Whatever the problem is with bluez-gnome, it seems that Blueman is able to resolve the problem, by allowing a 'connect to audio device --> headset' option, which worked for me. Not sure what it means, but I did manage to resolve my pairing problem:

Hi everybody,

same problem here:
Ubuntu 8.04 with all the updates
bluez-audio, -cups, -utils 3.26-0ubuntu6
bluez-gnome 0.25-0ubuntu1

trying to pair with a Dell D630 with Dell 360 Bluetooth chipset (Toshiba Stack).

[Mario Limonciello (superm1)]

Can someone retest this on Intrepid? The functionality should be better now.

[Adilson Oliveira (agoliveira)]

I just received a new GPS device Holux 1000B that works perfectly with my Nokia 810 but I can't authenticate on my 8.10 notebook. Looks like this is the same problem.

Adilson,

I wan't to pair my Bluetooth GPS (PIN:0000) and my headset (Samsung WEP200) and it not work because popup is to fast to close...

I don't test with Blueman because no package was ready for Intrepid and compiled of source don't work for me (i have no time now to check why...)

[John Pye (jdpipe)]

This was fixed for me in Intrepid. I notice that the pairing process seems to have changed quite a bit. My old pairing from Hardy needed to be deleted and re-paired, then the headphone worked as it should. Tested with both rhythmbox (using .a2dp/toggle.sh), and Skype.

[Richard Mitchell (mitchellrj)]

Same here trying to pair with a Jensen WBT210. Hardy too, same packages.

[Murz (murznn)]

Confirm the problem on Ubuntu Intrepid i386 with latest updates only
and with additional bluez, compiled from sources:
    * bluez-4.26.tar.gz
    * bluez-gnome-1.8.tar.gz

  sudo hcitool cc 00:19:DB:0A:xx:yy && sudo hcitool auth 00:19:DB:0A:xx:yy

a notifier window will pop up for ~1 second and then disappear.

If I click on the notifier window fastest, the main passcode/pincode entry dialogue will disappear. This also disappears within 1second.

[Murz (murznn)]

setting the command
sudo hciconfig hci0 auth
before connecting helps me to prevent disappearing the pin dialog.
I have find this method here:
https://bugs.launchpad.net/fedora/+source/bluez-gnome/+bug/284994/comments/90

1) First operations is finding the GPS device address with this command:

hcitool scan
Scanning ...

 00:13:F1:01:40:AE BT-GPS 0140AE

 00:18:8D:11:5F:F3 Zinux6680

Record the BT-GPS address, this is used later.

2) Enable the authentication on the pc blue-tooth dongle.

sudo hciconfig hci0 auth

3)Create a connection with the device
sudo hcitool cc 00:13:F1:01:40:AE

Now a popup menu request the pin for the device, insert it.

[Baptiste Mille-Mathias (bmillemathias)]

Could you try with jaunty development version or a Jaunty Live CD, I expect that to be fixed.

[Murz (murznn)]

I have updated my Kubuntu Intrepid to Jaunty beta1 (config-files of bluetooth reset to default), try to pair device. Mobile phone sees my computer, I try to pair, sets the password, but I can't see the pair dialog on KDE and see the error pairing process on mobile phone.

P.S. Bluez have been updated to bluez-4.34 which includes:
This release add more advanced features to the audio support for Handsfree/Headset profiles and also A2DP. Advanced system like PulseAudio should now be able to better interact with BlueZ and also have more control over multi-profile devices.

But Jaunty have a 4.32-0ubuntu4 version. Will be good to see 4.34 in Jaunty!

[Mario Limonciello (superm1)]

As indicated by one of the posters, this was fixed in Intrepid (with the bluez4.x stuff). Closing the bug.

[PaulSchulz (paulschulz)]

I am seeing this bug in Ubuntu 23.10.
bluez 5.68-0ubuntu1.1

Hardware: Logi POP Keys
https://www.logitech.com/en-au/products/keyboards/pop-keys-wireless-mechanical.920-011226.html

I have managed to have it working in the past, but the 6-digit code pop-up disappears very quickly (as described, <1sec).

[PaulSchulz (paulschulz)]

- This occurs on my daily use laptopm which has been upgraded from 23.04 -> 23.10

- I have just tried to pair on another laptop with freshly installed 23.10
  - The dialog displaying the pairing code persists
    and I can pair correctly with same keyboard (it can pair with 3 separate devices)
  - bluez 5.68-0ubuntu1.1

[PaulSchulz (paulschulz)]

Resetting the bluez package did NOT fix the problem.
  Removing the bluez package(s), removing /var/lib/bluetooth and re-installing.

  sudo apt remove --purge bluez
  rm -rf /var/lib/bluetooth
  sudo apt install bluez gnome-bluetooth gnome-bluetooth-sendto

The bluetooth system need to be started, and this empties the list of discovered bluetoothe devices,
but the popup for the keyboard auth number disappears again.
