It bluetooth on linux gets stuck in airplane mode it may disappear even from the hardware list, if this happens on a desktop computer that lacks an airplane mode switch, it can be confusing even seemingly impossible to bring back.

Here is a quick and simple solution:

Reboot and add the following argument to your kernel boot options at startup:

acpi_osi=! acpi_osi="Windows 2009"
