Bluetooth - sometimes

I’m not sure I understand your question: “Did you happen to resume from a suspended state, or do a full reboot?”
What’s a suspended state?
I just used the command lsmod, afterwards I installed “rfkill” with yast and then it used “rfkill list”.

Anyway, today I turned on the computer and bluetooth is working. May be just by chance or may be because I’ve installed “rfkill”.
Here are the outputs form

lsmod:

ath3k                  13317  0 
bluetooth             396742  33 rfcomm,bnep,ath3k,btusb
rfkill                 26487  4 cfg80211,bluetooth

rfkill list:

0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no
1: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no

So the output is different. Since it’s working today, I shall not try “sudo systemctl restart bluetooth” now. And I will wait and try that when bluetooth is not working and see what happens.
Thanks
