bluetooth.service running, but bluetoothctl says “org.bluez.Error.NotReady”

Question

my raspberry pi 3 model B, running Arch, has an issue with bluetooth. First of all:

• Bluetooth has worked flawlessly previously
• pi-bluetooth from the AUR is up to date
• bluez and bluez-utils are up to date
• The system is up to date as well (just ran pacman -Syu)

Still, when I try to use the bluetooth interface, it doesn't work.

bluetoothctl (as root), when I run "scan on", tells me

Failed to start discovery: org.bluez.Error.NotReady

wminput can't find the bluetooth interface:

No Bluetooth interface found
unable to connect

"systemctl status bluetooth" has the following output:

● bluetooth.service - Bluetooth service

I am at my wits end here, everything seems to be fine, yet nothing works. What is going on here?

Answer 1

Okay, wow, turns out all I had to do was run

bluetoothctl power on

Answer 2

I got the same problem. It turned that the @turf answer didn't work for me.

After I checked rfkill:

$ rfkill list
0: hci0: Bluetooth
        Soft blocked: yes
        Hard blocked: no
1: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no

I ran the command:

rfkill unblock all

And the Bluetooth worked again.
