Subject: When can I trust with bluetoothctl and 5.47?

Over and over again it says device is not available. When does it
become available? Is there a way to do this deterministically? I
quickly entered trust (it was saved from previous executions
unsuccessfully) after pairing. Then after connecting, all to no
avail.

Is there documentation on this?

The remote in this case is Broadcom 6.5.1.6000 stack.

I think bluetoothctl has a bug where it doesn't strip whitespace from
the beginning of arguments. In your case you have two spaces between
trust and the address. Try removing one.
