buetoothctl : Failed to connect: org.bluez.Error.NotReady

[janvda]

I tried to manually connect to my bluetooth speaker by means of the pulseaudio-server terminal window but I got the error Failed to connect: org.bluez.Error.NotReady.

Here below the full log:

I am also getting errors when running scan on

[bluetooth]# scan on
Failed to start discovery: org.bluez.Error.NotReady
Failed to set power on: org.bluez.Error.Failed
[bluetooth]#

stopping and starting the pulseaudio-server had no effect.
also stopping and staring the bluetooth deamon on the Host Os with following commands also had no effect: systemctl stop bluetooth and systemctl start bluetooth

rebooting the device fixed the problem:
