Summary: Every 5-20 minutes, the bluetooth mouse stops working.
Unprompted, it will reconnect and start working again. There are no
bluetoothd or kernel messages at the time of the disconnect, only
after reconnecting and working again are there messages. At the time
of the reconnect, the GNOME bluetooth icon in the upper right menu bar
area vanishes for ~2 seconds and reappears. The disconnect lasts
perhaps 10-30 seconds (varies).
On the same hardware (same mouse and laptop), the problem doesn't
happen when running Windows 10. And with a different laptop (a Mac)
the problem doesn't happen when running macOS, but does happen when
running Fedora. So it seems like a bug somewhere on the Linux side of
things but getting more debug info on why this is happening is eluding
me.
Fedora 28
4.17.0-0.rc7.git1.1.fc29.x86_64 (happens with 4.16, 4.15, 4.14 kernels)
bluez-5.49-3.fc28.x86_64
gnome-bluetooth-3.28.0-1.fc28.x86_64
bluetoothd is running with -d option to get debugging info
