Hi Francesco,

If 'device-wakeup-gpios' property is set. The bluetoothctl can work, but errors will show up if try to scan the bluetooth devices.

[bluetoothctl]> scan on
SetDiscoveryFilter success
Failed to start discovery: org.bluez.Error.InProgress
hci0 class of device changed: 0x000000

[CHG] Controller 20:BA:36:5C:B0:D8 Powered: no
[CHG] Controller 20:BA:36:5C:B0:D8 Discovering: no
[CHG] Controller 20:BA:36:5C:B0:D8 PowerState: on
[bluetoothctl]> discoverable on
Failed to set discoverable on: org.bluez.Error.Failed

After remove the 'device-wakeup-gpios' node. The bluetooth can work normally.
