Public bug reported: Since installing Ubuntu 11.10 (with Linux 3.0), Secure Simple Pairing (SSP) is broken and will not allow my SSP headset (Samsung HM1000, EDR + 2.1) to reconnect after initial pairing and disconnect. I am able to pair and connect at first. Before I diconnect, everything works as expected. But after disconnecting, I am no longer able to re-connect the headset. I have to un-pair then re-pair the device to connect again to get it working. After re-pairing the headset it stays connected until I disconnect. Then again after disconnecting, I am again not able to connect.
I have been using the same BT usb dongle and BT headset in Ubuntu 10.10, 11.04, and 11.10. Everything worked fine in Ubuntu 10.10 and 11.04, which I think were based on Linux Kernel 2.6.35 and 2.6.38 respectively. In those versions, I was able to pair and connect / disconnect / connect without issue. I posted an email on the Bluez developer mailing list and it seems that there is a known issue in the way SSP pairing is working (http://marc.info/?l=linux-bluetooth&m=132914064106062&w=2) in Ubuntu 11.10. It seems there is a patch that has been released to correct the issue: (http://marc.info/?l=linux-bluetooth&m=131292182215271&w=2), and a recommendation to incorporate the fix in stable releases (http://marc.info/?l=linux-bluetooth&m=132817560218886&w=2). I am able to work around the issue by running the command: sudo hciconfig hci0 sspmode 0 to disable sspmode to default back to legacy connection. However, after rebooting, I again have to disable sspmode in order to connect the headset. Seems like this is a very basic use case that left uncorrected can result in very poor user experience. ** Affects: bluez (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/931860 Title: Bluetooth Secure Simple Pairing SSP Broken To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/931860/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
