More data points: - When I try to connect from gnome-control-center, this error is logged:
bluetoothd[1635]: connect error: Device or resource busy (16) - Connecting *fails* from blueman-manager if gnome-control-center is open at the Bluetooth section at the same time. The same error is logged. When another section is selected in gnome-control-center, then blueman-manager will work. It's like if gnome-control-center is keeping the device busy (always scanning?), preventing connections. -- 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.
