Whenever I connect a Bluetooth speaker or headset, the device remains connected as long as it is in use. However, if it is not in use even for a few minutes, the Bluetooth automatically turns off. And when I try to switch it on again, it won't. I need to restart my laptop and then only Bluetooth works again.
Is there any way by which I can stop Bluetooth from turning off by itself? Also, why won't it start again without needing to restart the laptop?

See below for what worked for me. Bluetooth could not be toggled on or off from applet, nor from settings effectively. It just turned itself off for no reason. Reboot of OS would not work either. Here is someone else's fix and explanation that worked for me. PS Bluetooth applet image is still invisible.
update bluez to >=5.28.2
18.04 ships with a buggy bluez package for now; newer version is available from this PPA :
sudo add-apt-repository ppa:bluetooth/bluez sudo apt update sudo apt install bluez
I restart it in the terminal, and it works:
Code:
$ sudo -i
# bluetoothctl
[bluetooth]# power off
[bluetooth]# power on
[bluetooth]# scan on
[bluetooth]# connect XX:XX:XX:XX:XX:XX (your bluetooth address)
[Arc Touch Mouse SE]# trust
[Arc Touch Mouse SE]# pair
[Arc Touch Mouse SE]# unblock
[Arc Touch Mouse SE]# power off
[bluetooth]# power onMy problem is similar, but it happens only after the computer wakes up from the suspend. It only happens to Bluetooth speaker; there is no such issue with Bluetooth mouse. The current solution I find is to reboot the Bluetooth service bysudo service bluetooth restart.
