Bluetoothctl does not find my bluetooth headphones

I don't see any devices in bluetoothctl:

[bluetooth]# show

	Name: ralf-laptop
	Alias: ralf-laptop
	Class: 0x0000010c

[bluetooth]# devices
[bluetooth]#

rfkill list

	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no
2: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no

This is the first time am trying to use bluetooth on Linux, so I might be doing something wrong as well.

Re: Bluetoothctl does not find my bluetooth headphones

›devices‹ only shows devices known to the software. If you want to scan for devices surrounding you, you should use ›scan on‹. Example:

[bluetooth]# scan on
Discovery started
[CHG] Controller 98:2C:BC:2F:CE:CE Discovering: yes
[NEW] Device 18:62:E4:11:D7:EC Charger

Re: Bluetoothctl does not find my bluetooth headphones

Have you done

# systemctl start bluetooth

and checked

# systemctl status bluetooth

before starting bluetoothctl?

Re: Bluetoothctl does not find my bluetooth headphones

Thanks!
Turns out bluetoothctl does find some devices, but It does not find my headphones (at the time of my earlier trial there were none other on). While they work on my windows laptop and android phone.
Any ideas what could cause this?

Re: Bluetoothctl does not find my bluetooth headphones

Presumably the device you are trying to scan is set to pairing mode - when pairing my ear buds there was a button to push to put it in pairing mode. Also I presume you followed the bluetooth page in the arch wiki?
