Disconnection Timeout

[francois-fiveco]

Hi,
Sometimes, the HCI command "Disconnect" ends with "LMP Response Timeout / LL Response Timout" but bluetoothctl considers that it is always connected.
Is there a way to make bluetoothctl understand that the device is disconnected?

Btmon Disconnection succeeded :
