Today I turned on my notebook and everything was somehow ok inside dmesg related to bluetooth. After that I turned off-on for some 15 times - every time with bluetooth error.
Bluetooth turned on inside Ubuntu settings: dmesg | grep -i bluetooth [ 1.732360] Bluetooth: Core ver 2.21 [ 1.732371] Bluetooth: HCI device and connection manager initialized [ 1.732373] Bluetooth: HCI socket layer initialized [ 1.732375] Bluetooth: L2CAP socket layer initialized [ 1.732380] Bluetooth: SCO socket layer initialized [ 1.743346] Bluetooth: hci0: Firmware revision 0.0 build 90 week 25 2015 [ 1.848901] Bluetooth: HCI UART driver ver 2.3 [ 1.848904] Bluetooth: HCI UART protocol H4 registered [ 1.848906] Bluetooth: HCI UART protocol BCSP registered [ 1.848907] Bluetooth: HCI UART protocol LL registered [ 1.848908] Bluetooth: HCI UART protocol ATH3K registered [ 1.848909] Bluetooth: HCI UART protocol Three-wire (H5) registered [ 1.848932] Bluetooth: HCI UART protocol Intel registered [ 1.848945] Bluetooth: HCI UART protocol BCM registered [ 1.848946] Bluetooth: HCI UART protocol QCA registered [ 2.831762] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 2.831764] Bluetooth: BNEP filters: protocol multicast [ 2.831768] Bluetooth: BNEP socket layer initialized [ 4.928101] Bluetooth: RFCOMM TTY layer initialized [ 4.928178] Bluetooth: RFCOMM socket layer initialized [ 4.928182] Bluetooth: RFCOMM ver 1.11 Bluetooth turned off inside Ubuntu settings: dmesg | grep -i bluetooth [ 1.874571] Bluetooth: Core ver 2.21 [ 1.874584] Bluetooth: HCI device and connection manager initialized [ 1.874587] Bluetooth: HCI socket layer initialized [ 1.874589] Bluetooth: L2CAP socket layer initialized [ 1.874596] Bluetooth: SCO socket layer initialized [ 1.884772] Bluetooth: HCI UART driver ver 2.3 [ 1.884774] Bluetooth: HCI UART protocol H4 registered [ 1.884775] Bluetooth: HCI UART protocol BCSP registered [ 1.884776] Bluetooth: HCI UART protocol LL registered [ 1.884777] Bluetooth: HCI UART protocol ATH3K registered [ 1.884779] Bluetooth: HCI UART protocol Three-wire (H5) registered [ 1.884800] Bluetooth: HCI UART protocol Intel registered [ 1.884811] Bluetooth: HCI UART protocol BCM registered [ 1.884812] Bluetooth: HCI UART protocol QCA registered [ 2.018145] Bluetooth: hci0: Bootloader revision 0.0 build 2 week 52 2014 [ 2.023135] Bluetooth: hci0: Device revision is 5 [ 2.023138] Bluetooth: hci0: Secure boot is enabled [ 2.023139] Bluetooth: hci0: OTP lock is enabled [ 2.023140] Bluetooth: hci0: API lock is enabled [ 2.023140] Bluetooth: hci0: Debug lock is disabled [ 2.023141] Bluetooth: hci0: Minimum firmware build 1 week 10 2014 [ 2.039100] Bluetooth: hci0: Found device firmware: intel/ibt-11-5.sfi [ 2.063532] Bluetooth: hci0: Failed to send firmware data (-38) [ 4.066208] Bluetooth: hci0 command 0xfc05 tx timeout [ 4.225754] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 4.225757] Bluetooth: BNEP filters: protocol multicast [ 4.225759] Bluetooth: BNEP socket layer initialized [ 8.944807] Bluetooth: hci0: Reading Intel version information failed (-19) [ 9.346262] Bluetooth: hci0: Bootloader revision 0.0 build 2 week 52 2014 [ 9.351267] Bluetooth: hci0: Device revision is 5 [ 9.351269] Bluetooth: hci0: Secure boot is enabled [ 9.351270] Bluetooth: hci0: OTP lock is enabled [ 9.351287] Bluetooth: hci0: API lock is enabled [ 9.351288] Bluetooth: hci0: Debug lock is disabled [ 9.351289] Bluetooth: hci0: Minimum firmware build 1 week 10 2014 [ 9.351433] Bluetooth: hci0: Found device firmware: intel/ibt-11-5.sfi [ 10.715096] Bluetooth: hci0: Waiting for firmware download to complete [ 10.715250] Bluetooth: hci0: Firmware loaded in 1337743 usecs [ 10.715320] Bluetooth: hci0: Waiting for device to boot [ 10.727323] Bluetooth: hci0: Device booted in 11762 usecs [ 10.730228] Bluetooth: hci0: Found Intel DDC parameters: intel/ibt-11-5.ddc [ 10.732332] Bluetooth: hci0: Applying Intel DDC parameters completed [ 10.733322] Bluetooth: hci0: Setting Intel event mask failed (-16) [ 10.788864] Bluetooth: RFCOMM TTY layer initialized [ 10.788883] Bluetooth: RFCOMM socket layer initialized [ 10.788886] Bluetooth: RFCOMM ver 1.11 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1553694 Title: Lenovo Y700-17ISK: Bluetooth issues To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1553694/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
