Hi Stefan,

Here is what happens with mouse,

1. When you use the mouse, they are in active mode, and after that they go
to sniff mode.
2. Now if continue not using mouse eventually it will disconnect (when it
disconnects depends on the sniff Interval, and sniff timeout).
3. When the mouse transitions to Sniff Mode from Active mode one would see
Mode change event along with Sniff Parameters which i told you about.
4. Now only after disconnect will you observe that the hid reconnects.

Please read section 8.7 in baseband specification of Bluetooth specs which
will throw more light into question which you are posing i.e. if you have
access to it.

Or else I can share it with you.

Cheers,
Venu
