I've been at this for a couple weeks now. I cannot for the life of me get Bluetooth working on my E585. It's a combo Wifi+BT m.2 card, Realtek RTL8822BE, device ID 0bda:b023
It's listed as certified by Ubuntu, but it flat-out will not work. https://certification.ubuntu.com/catalog/component/usb/286/0bda%3Ab023/
I have pretty much the latest everything. Kernel 4.18.5, latest firmware, etc. I have a thread open on ubuntuforums.org with lots of details.
I'm about to just give up on it and order a new wifi+bt card.. but obviously I'd prefer to resolve this.

Strange behavior indeed. If I boot from power on -> bluetooth does not work. But if I suspend, then wake, it does.
I tried disabling and re-enabling the radio, but it seems that it is a warm start that triggers the bluetooth to be discovered.

People using Ubuntu 18.04 with the 4.15 kernel can try my fix at https://github.com/jeremyb31/newbtfix-4.15
I just added the 0bda:b023 ID to the btusb.c source code
