Bluetooth suddenly disconnects from the speaker

[Saverio Miroddi]

This bug happens very often.

I have a Foxl2 speaker, which is connected via bluetooth to my computer (Thinkpad W520).

Regularly, the connection suddently drops.

Note that the speaker doesn't disconnect when it's connected to my mobile phone instead.

HCI log attached.
