DisconnectAsync() takes ~1.7s to complete

[boborjan2]

Description

Disconnecting takes more time than expected. Even in the simplest case (disconnect immediately follows connect), it takes approx 1.7s. Other operations (connect, write etc) are prompt.

Environment

Linux debian trixie, bluez 5.82

• Linux.Bluetooth Version: tried with: 5.67.1, 6.0.0-pre3
  Tmds.DBus" Version="0.94.1

Severity (1-5)

2

Expected Behavior

Disconnect should be fast. Or is bluez that slow? I wonder.

When performing a disconnect using other Bluetooth system on your same device that it was tested on, how long does it take? The disconnect operation is pretty straight forward.
