PureOS Bluetooth Visibility is On By Default. Can I turn it off?

Software PureOS
1

Bluetooth visibility should not be “ON” as default as it creates a privacy issue.
In the past few days, I managed to disable the “AutoEnable” bluetooth.

However, even when I turn off visibility manually, when I restart Bluetooth it comes back on…
Is there any way I can disable the visibility permanently?

Thanks

How did you do it per session?

I imagine you’ll have to modify the systemd bluetooth service file, but I can’t give you more info than that.

How did I turn it off?

sudo btmgmt
[mgmt]# select hciX # select a known device by index X eg. hci0
[hci0]# discov yes # make hci0 visible/discoverable
[hic0]# discov no # make hci0 invisible

However, it doesnt produce lasting efects.

I have turned off the AutoEnable, by modifying /etc/bluetooth/main.conf
