#243577 — How to use bt-... suite of Bluetooth tools?

I'm trying to connect my Bluetooth earbuds to my laptop. It works
interactively using bluetoothctl, but not with bt-adapter and bt-device.

First, bluetoothctl:

$ bluetoothctl
Agent registered
[bluetooth]# devices
Device 1C:52:16:CA:E7:D9 SOUNDPEATS TrueFree
[bluetooth]# connect 1C:52:16:CA:E7:D9
Attempting to connect to 1C:52:16:CA:E7:D9
[CHG] Device 1C:52:16:CA:E7:D9 Connected: yes
Connection successful
[CHG] Device 1C:52:16:CA:E7:D9 ServicesResolved: yes
[SOUNDPEATS TrueFree]# disconnect 1C:52:16:CA:E7:D9
Attempting to disconnect from 1C:52:16:CA:E7:D9
[CHG] Device 1C:52:16:CA:E7:D9 ServicesResolved: no
Successful disconnected
[CHG] Device 1C:52:16:CA:E7:D9 Connected: no
[bluetooth]# quit
$

That works fine. Now, using bt-adapter and bt-device, the process times
out when trying to connect to the device. Do I need to take extra steps
in setting up the adapter? I'm assuming that bluetoothctl and bt-xxx
use the same librery under the hood.

Thanks!

Here's the shell transcript of the bt-... session:
