Bluetooth keeps turning on after suspend

Question

I have tried to turn off Bluetooth, but every time I close and re-open the lid of my laptop, the Bluetooth service is up and running again. Having Bluetooth on seems to interfere with my wifi connection when I am far away from the router(OT, but is this normal?).

I have read up on rfkill and even when I run rfkill block bluetooth, the same thing happens after I close and re-open the lid.

Any ideas how to stop this behaviour? To be clear, I do want to be able to use Bluetooth occasionally, but I want it turned off by default.

The machine is an Asus nv56m and the ubuntu version is 19.04

To disable Bluetooth on resume after suspend

1. Create a script disabling Bluetooth in file /path/to/file/disable-bluetooth.sh

   #!/usr/bin/env bash
   
   rfkill block bluetooth
   

2. Make it executable

   $ chmod +x /path/to/file/disable-bluetooth.sh
   

3. Create a file /etc/systemd/system/disable-bluetooth.service

   [Unit]
   Description=Disables Bluetooth
   Before=sleep.target
   StopWhenUnneeded=yes
   
   [Service]
   Type=oneshot
   RemainAfterExit=yes
   ExecStop=/path/to/file/disable-bluetooth.sh
   
   [Install]
   WantedBy=sleep.target
   

4. Enable the service

   $ sudo systemctl enable disable-bluetooth.service
