bt-adapter dumps core, unable to use Bluetooth

No idea at which point, but now bluetooth has stopped working which is a big bummer for me (bt headphones)

I've tried on the console to use bluetoothctl but no avail, says

[bluetooth]# devices
No default controller available

This is what I'm seeing in the console if I try to restart it or launch it via the menu of Cinnamon.

I'm on a DELL XPS 13 (late 2016).

Hope someone knows what's going on, or otherwise I'll report upstream (don't know where this would be long thou)

Re: bt-adapter dumps core, unable to use Bluetooth

I just got bit by this today. Not sure what caused it since it was working fine previously.

It fixes itself if I open blueberry.

Re: bt-adapter dumps core, unable to use Bluetooth

I just experienced this issue as well on a DELL XPS 13 9360 and it turns out that the bluetooth chip seems to have a bug where you need to physically turn off the laptop (systemctl poweroff) and turn it back on again. Realized this after debugging the issue for a few hours... Hopefully this helps someone searching this issue.

Cheers
