I have an Ember Mug which is a BLE device. I was able to pair it to my
Fedora 39 system running bluez-5.72 with a:
Bus 003 Device 029: ID 0bda:8771 Realtek Semiconductor Corp. [unknown]
BT dongle. But now it seems unable to reconnect, automatically[1], or
otherwise (I have no idea why bluetoothctl's prompt is "Bluetooth Mouse
M557]" but it is):
$ bluetoothctl

Any ideas?
[1] Am I safe in understanding that this BLE device should just
automatically connect to bluez once it's within vicinity of the BT
adapter?
Cheers,
