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.
Could you connect other bluetooth heapdhones to your laptop? Let's see if it is the problem on your laptop (bluetooth hci controller). If it is, it is highly possible that it is bluetooth driver or firmware's problem. Could you connect your redmi headphone to other laptops? If yes, you could capture bt packages during the reconnection and compare them: close gnome bluetooth applet, $sudo btmon -w good.cap $btmon -r good.cap on the machine with problem: $sudo btmon -w bad.cap $btmon -r bad.cap -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1879582 Title: [Redmi AirDots Bluetooth] I need to remove device in settings every time i want to connect again To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1879582/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
