Bluetooth: hci0: Opcode 0x 401 failed: -16 when trying to connect to Bluetooth speaker

[Bric]

Hello,
I recently format my Slimbook ProX 14. I had Ubuntu 22.04.2 LTS and I reinstall the same version to have a fresh install.
I have a bluetooth speaker (UE BOOM 2), since the reinstallation, I can't connect to it. I have the error in /var/log/kern.log:
Apr 9 21:14:33 me-pc kernel: [42022.714261] Bluetooth: hci0: Opcode 0x 401 failed: -16
Apr 9 21:14:37 me-pc kernel: [42027.157322] Bluetooth: hci0: Opcode 0x 401 failed: -16

I can see correctly the speaker in the list of available devices.

I also tried to install blueman-manager but the problem is the same:

I had a similar issue with Nothing Ear(2) headphones that there would be the error message "Bluetooth: hci0: Opcode 0x 401 failed: -16". This error message would happen with Intel AX200 as the bluetooth controller (Dell XPS 15 7590).
The workaround for the problem is to disable Bluetooth LE while pairing the device. Here's how to do that: https://askubuntu.com/a/833323 (temporarily add "ControllerMode = bredr" to /etc/bluetooth/main.conf).
