Bluetooth devices doesn't get listed while turn off and then on

[Raghuvar Prajapati]

When System Starts, first time Bluetooth devices(Say headphones) get connected smoothly. But after a point when headphones get disconnected, If I tried to reconnect Bluetooth settings don't list the devices. I turned it on/off multiple times but doesn't work. The only way that'd work after a system restart. Please can you check into this

The log has those warnings
'Bluetooth: hci0: unexpected event for opcode 0x2005'
It's more likely to be a kernel issue

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1849183

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Those kernel messages are not uncommon and probably not related to this bug.
