I tried to specify the udev rule more precisely, i.e. only power up a host controller. Is there anybody could give it a try?
#/lib/udev/rules.d/50-bluetooth-hci-auto-poweron.rules # Set bluetooth power up ACTION=="add", SUBSYSTEM=="bluetooth", KERNEL=="hci[0-9]*", ENV{DEVTYPE}=="host", RUN+="/bin/hciconfig %k up" -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1510570 Title: BLE pairing fail Status in bluez package in Ubuntu: Confirmed Bug description: On 15.10 we now have bluez 5 so we can pair BLE devices like the Microsoft Arc Touch Bluetooth Mouse. But this pairing doesn't work very well. Mouse is seen but pairing fail. More information: https://bugzilla.kernel.org/show_bug.cgi?id=104011#c5 This is due to udev rule that use "hcitool" to power on device. Hopefully, bluez 5.35 has a new parameter "AutoEnable" who can be used instead of udev rules. here is a commit with this parameter: http://bazaar.launchpad.net/~guilhem-fr/bluez/autoenable/revision/138 And a ppa to test it: https://code.launchpad.net/~guilhem-fr/+archive/ubuntu/bluez-autoenable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1510570/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
