Thank you for your bug report, could you try to uninstall blueman and see if it works better with the default installation software?
Can you connect the device from bluetoothctl when you get the issue from gnome-control-center? Could you add your 'journalctl -b 0' log to the bug after getting the issue? ** Changed in: gnome-control-center (Ubuntu) Importance: Undecided => Low ** Changed in: gnome-control-center (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1870356 Title: Can't connect to paired bluetooth devices via g-c-c; works with blueman Status in gnome-control-center package in Ubuntu: Incomplete Bug description: I have a paired bluetooth device listed as "Disconnected" in the Bluetooth section of gnome-control-center. In order to connect to it I click on the device name and switch the "Connection" slider to the "on" position. The slider moves but immediately bounces back to the "off" position, and nothing happens: the connection is not established. It never works even if I try several times. This happens on an up-to-date Focal system and it's always reproducible across reboots and power cycles of the device. I don't think it's a problem of the device itself or of the underlying bluetooth stack, as connecting/disconnecting to the device works perfectly if I use bluetooth-manager instead of gnome-control-center. I don't know if this is a regression as I was not using bluetooth before installing Focal. FWIW (very little), the device connects/disconnects perfectly to Android phones.
