When pressing on the device in the list of devices available in the Bluetooth menu, it either doesn't connect or it sometimes "falsely" connects, meaning that it appears in Ubuntu to have connected, but it did not if I check the other device. (device is not connected). Tried restarting Bluetooth service, no success. Maybe I can somehow "hard-reset" the Bluetooth service? I can provide any logs if requested.

Edit: Updated from 20.04 to 20.10, no result.

Edit: sudo tail -f /var/log/kern.log prints:

Bluetooth: hci0: command 0x200c tx timeout

Bluetooth: hci0: No way to reset. Ignoring and continuing

Bluetooth: hci0: HCI reset during shutdown failed

Edit: when trying to connect via bluetoothctl to speaker, I get:

Failed to connect: org.bluez.Error.Failed

Simply powering off the pc and turning off and on the power supply did the trick!
