** Description changed: - [Description] + [ Impact ] - Since Noble, turning Bluetooth slider on ON after toggling it OFF for - ~1min seems to only power on and unblock rfkill on the controller, but - not enable scanning. This makes the "Devices" list shows no devices, as - if the controller wasn't functioning. + * Turning off bluetooth for over 1 minutes and turn on it in bluetooth panel. + There is no devices list, and the bluetooth controller is not discoverable. - This is observable on both Dell XPS 13 Plus and HP Elite Book 1040 x360 - with stock Noble image. + [ Test Plan ] - Note that manually executing "scan on" command in the bluetoothctl will - make scanning in g-c-c back to normal. + * Find a machine with bluetooth as the device under test (DUT) - Also note that if leave the Bluetooth slider on, switch to another tab - in settings, and switch back to the Bluetooth tab, this will somehow - activate scanning again. New devices will pop up again in the "Devices" - list. + * Open g-c-c bluetooth panel on the DUT - [Steps to reproduce] + * Turn off the bluetooth on the DUT for 1 minutes - 1. Open the control center and switch to the Bluetooth tab. - 2. Toggle ON and OFF the Bluetooth slider and leave it at OFF for 1 minutes. - 3. Turn it back on. - 4. At this moment the devices listed "Device" will disappear one by one, and - eventually no device will present. + * Put another bluetooth gadget to discovery mode + + * Turn on the bluetooth on the DUT in the bluetooth panel + + * There should be bluetooth device listed, and the DUT is also + discoverable + + [ Where problems could occur ] + + * The powered status is recorded by bluez, if the status in bluez and + hardware is asynchronous. It still has problem to put the device into + discovery mode. + + [ Other Info ] + + * Upstream, + https://gitlab.gnome.org/GNOME/gnome-bluetooth/-/commit/de707f592304309a59208e3ed1afbe4a37568bdd + https://gitlab.gnome.org/GNOME/gnome-bluetooth/-/commit/3d45205c79b48dd3e15e1c4edb58cf8cd79f23ef
