when I type scan on at the prompt of bluethootclt However my system is not able to discover many of the bluethoot devices. I have tested against my phone and other linux laptop. So the message **IS AFFECTING** the Bluetooth functioning since the system does not connect to many of the devices. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1748565 Title: Kernel regularly logs: Bluetooth: hci0: last event is not cmd complete (0x0f) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1748565/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
