Likely same or very similar bug on Ubuntu 17.04 with Intel 7260 bluetooth hardware [8087:07dc]. Disabling Bluetooth causes indicator icon to disappear. I can make it reappear again, albeit usually in a disabled state, by enabling Bluetooth in control centre. Then to actually enable, I must enable via indicator as the last step. (Alternatively switch on->off->on in Control centre, which also finally enables Bluetooth again.)
RF-kill and device states: 0. Bluetooth enabled and indicator icon visiable (normal): - "hcitool dev" shows 1 device - 3: dell-bluetooth: Bluetooth Soft blocked: no Hard blocked: no 1. After disabling Bluetooth via indicator icon (causing icon to disappear) - "hcitool dev" shows no devices - 3: dell-bluetooth: Bluetooth Soft blocked: yes Hard blocked: no 2. Enable Bluetooth in control centre Most often goes to state where a device is present, but still soft blocked, and indicator icon reappears in a disabled state. Sometimes it works as expected the first time and fully enables Bluetooth radio. This is what my system logs tell me when I disable Bluetooth: april 30 09:52:55 lhs systemd[1]: Starting Load/Save RF Kill Switch Status... april 30 09:52:55 lhs systemd[1]: Started Load/Save RF Kill Switch Status. april 30 09:52:55 lhs kernel: usb 1-1.3: USB disconnect, device number 10 april 30 09:52:55 lhs bluetoothd[883]: Endpoint unregistered: sender=:1.3932 path=/MediaEndpoint/A2DPSource april 30 09:52:55 lhs kernel: Bluetooth: hci0: turning off Intel device LED failed (-19) april 30 09:52:55 lhs systemd-rfkill[17256]: Failed to open device: No such device april 30 09:52:55 lhs bluetoothd[883]: Endpoint unregistered: sender=:1.3932 path=/MediaEndpoint/A2DPSink april 30 09:52:55 lhs dbus[865]: [system] Rejected send message, 3 matched rules; type="error", sender=":1.3932" (uid=1000 pid=12977 comm="/usr/bin/pulseaudio --start --log-target=syslog ") interface="(unset)" member="(unset)" error name="org.bluez.MediaEndpoint1.Error.NotImplemented" requested_reply="0" destination=":1.17" (uid=0 pid=883 comm="/usr/lib/bluetooth/bluetoothd ") april 30 09:52:55 lhs dbus[865]: [system] Rejected send message, 3 matched rules; type="error", sender=":1.3932" (uid=1000 pid=12977 comm="/usr/bin/pulseaudio --start --log-target=syslog ") interface="(unset)" member="(unset)" error name="org.bluez.MediaEndpoint1.Error.NotImplemented" requested_reply="0" destination=":1.17" (uid=0 pid=883 comm="/usr/lib/bluetooth/bluetoothd ") april 30 09:52:55 lhs dbus[865]: [system] Rejected send message, 3 matched rules; type="error", sender=":1.3932" (uid=1000 pid=12977 comm="/usr/bin/pulseaudio --start --log-target=syslog ") interface="(unset)" member="(unset)" error name="org.bluez.MediaEndpoint1.Error.NotImplemented" requested_reply="0" destination=":1.17" (uid=0 pid=883 comm="/usr/lib/bluetooth/bluetoothd ") april 30 09:52:55 lhs systemd[1]: bluetooth.target: Unit not needed anymore.

I do not yet know what conditions are required for it to not fully enable the first time, which is what I usually experience.) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to indicator-bluetooth in Ubuntu. https://bugs.launchpad.net/bugs/1595695 Title: bluetooth indicator disappears every time bluetooth is being turned off Status in indicator-bluetooth package in Ubuntu: Confirmed Bug description: In Ubuntu 16.04, every time I turn off bluetooth, the indicator icon disappears from the top panel. Each time I have to re-enable it by system setting or via dash. I expect it to behave in a same way as network indicator instead of disappearing.
