Bluetooth adapters
1.Some Bluetooth adapters are bundled with a Wi-Fi card (e.g. Intel Centrino). These require that the Wi-Fi card is firstly enabled (typically a keyboard shortcut on a laptop) in order to make the Bluetooth adapter visible to the kernel.
2.Some Bluetooth cards (e.g. Broadcom) conflict with the network adapter. Thus, you need to make sure that your Bluetooth device gets connected before the network service boot.

bluez-utils bluetoothctl utility
Install the bluez-utils package, providing the bluetoothctl utility.
Since Sept 2016’s release of Bluez5.42, many packages that online guides use were deprecated (https://wiki.archlinux.org/index.php/Bluetooth#Troubleshooting). Oh, and the Bluez package is severely lacking in official documentation.
Some tools such as hcitool and hciconfig have been deprecated upstream, and are no longer included in bluez-utils. Since these tools will no longer be updated, it is recommended that scripts be updated to avoid using them.

bluetoothctl
btmgmt
There is a bug with some motherboard bluetooth controllers.
To see if this might be the issue, run journalctl | grep hci. If there are entries like "command tx timeout" or "Reading Intel version command failed", then power off your pc and physically unplug the power cable for a few seconds. This forces the controller to reload the firmware (while a standard reboot will not).
