About the Philips SHB3075, i had tested just for music. I had borrow
that, so, i didn't do more tests. What is the handsfree service? The
volume control in that phone worked independent, regardless, from volume
in the system.

Hi! I had test the same redmi airdots in more scenarios, that led me to
guess that, while autoconnection is not a bug, manual connection is
really an Ubuntu bug, since it worked fine in Linux Mint 19.3 in the
same hardware.
These was the new tested cenarios (all these with redmi airdots phone):

If the handsfree is not a critical service feature, even the laptop
reply that it doesn't support this service, the redmi phone should

According to the log, when autoconnection fails:
Redmi phone sent (Handsfree):
> ACL Data RX: Handle 11 flags 0x02 dlen 17
>
> #37 [hci0] 9.000527
autoconnection works.
Besides the auto-connection bug is just with redmi+ubuntu, manual connections
(and disconnections) are also useful if you use the same headphone in more than
one device.

I tested a third headphone, Philips SHB3075, in my acer laptop, and
autoconnection works, but manual reconnections not. For manual
connections is the same than for redmi, i had to try connect a lot of
times than it works.

If there is no log from pulseaudio, it means the pulseaudio does not
join the connection process yet. The pulseaudio needs to receive a Dbus
message (connection request) from bluez first, then it starts to
processing bluetooth connection. So in your case, the connection failed
in the bluez.

Hi, thanks for help. When i manually try to connect in ubuntu settings,
yes, there are this messages:
May 20 12:50:29 felipe-Nitro-AN515-52 bluetoothd[1257]: Unable to get Headset
Voice gateway SDP record: Device or resource busy
May 20 12:50:29 felipe-Nitro-AN515-52 bluetoothd[1257]: connect
When the bluetooth headphone is trying to connect on the 2nd time (will
fail), could you see any error message from syslog?
open a terminal and run 'tail -f /var/log/syslog', then reconnect the
bluetooth headphone.
