Bluetooth devices get disconnected.
Hi.
I am running Debian Sid with KDE. I have Logitech MX 2 and Bose
Bluetooth headphones. I experience disconnects very often.
I tried to use different configuration, but nothing seems to work.
After running the following the mouse gets connected again, and I can
reconnect BT headphones also. However the devices get disconnected again
in 1, 5 or 10 minutes again:
hciconfig hci0 sspmode 1
hciconfig hci0 down
hciconfig hci0 up
I also noticed that when the mouse is working I see the following:
$ hciconfig -a

After disconnect I can see the following:
$ hciconfig -a

I also configured blutoothd with -d option, but I don't see any specific
messages when the devices disconnect.
Any thoughts how to fix it or debug it? Is this general bluetooth issue
or KDE bluedevil problem?
Thanks Jiri
