Bug Description

I have a bluetooth mouse (Genius Traveller 9005BT) that I have been using without problems with Ubuntu for over a year. Since a few weeks ago, however, it started disconnecting and reconnected from the computer. The symptoms are like this:

1. The mouse works, and the bluetooth icon on the computer is visible (in gnome-shell's top bar)
2. The mouse stops working, but the bluetooth icon is still visible. This state lasts between 1 and 10 seconds.
3. The bluetooth icon vanishes. This can last for half a second if I keep trying to use the mouse, to forever I I leave the mouse alone
4. The bluetooth icon reappears and the mouse starts working again. This state last from 2-3 seconds if I don't move the mouse, to seemingly forever if I continuously move the mouse

This seems to occur only after a suspend/resume cycle, and rebooting the computer fixes the issue.

The only thing I see in syslog is this when the mouse reconnects:

I just noticed that I can do this instead of rebooting to work around the issue:
sudo hciconfig hci0 down
sudo hciconfig hci0 up

I can confirm this is also a problem in Vivid. I'm not using the same mouse but symptoms are pretty much the same(except the BT icon doesn't always disappear) . I've updated the kernel to 3.19.2 (for other reasons - HDMI audio was broken) but that didn't help the bluetooth issue (I'm assuming it's a bluez problem rather than the kernel itself). Happy to help troubleshoot if someone can guide trough the relevant processes to monitor.

Same for me with Microsoft Sculpt Comfort mouse on different machines with Ubuntu 16.04/10. Mouse keeps disconnection every few minutes and the reconnects again. No visible issue in logs, just info about reconnection.

@mcumpa could you post the syslog as well as HCI trace for your case?

1. syslog

Please enable the debug output first by typing:

$ sudo sed -i 's/bluetoothd/bluetoothd \-d/g' /lib/systemd/system/bluetooth.service

2. HCI trace


$ sudo btmon --write ~/hcitrace.snoop

before you start reproducing the issue [but might be after pairing to limit the log size]. It is important not to make the test too long so that the HCI trace is easier to read and understand.
