indeed "bluetooth" is installed and enabled in systemd. But ... I don't see what it has to do with the fact that when I use "bluetooth" command line to power the device off, it tells me it's off, but is not really.
Would you suggest that I do a `systemctl stop bluetooth` instead of simply 'turn off with GUI' ?
Would be worth a try I guess but if it's true, what's the point in having a power on/off feature ?
I have a dell XPS13 9350, it works fine. I used to turn Bluetooth Off and On through gnome dropdown menu. Fine.
BUT I recently checked my laptop radiowaves emissions ... and even when bluetooth is OFF, and wifi is OFF (gnome displays the nice 'airplane mode' icon) : my latop emits steadily bluetooth signal !
I checked with 'bluetooth' command line : the adapter is seen, and has power=off status.
I cannot pair anything, that sounds logical I just mention it to say I tried : and the laptop is not seen as a pairable bluetooth device. But still it emits radiowaves.
Any idea what I can try ?
thx
