I have a problem with my bluetooth adapter. Can't turn it on, and i followed some tutorials to fix that, but with no luck. It seems to be soft blocked, I run the command to soft unblock, the icon in taskbar goes white for a 0.5 second and then is switched back. how can i unblock this? here is the output of console when I run rfkill list all :

0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: hp-wifi: Wireless LAN
    Soft blocked: no
    Hard blocked: no
2: hp-bluetooth: Bluetooth
    Soft blocked: yes
    Hard blocked: no

I used sudo rfkill unblock bluetooth to unblock bluetooth. Thanks.

UPDATE (by cipricus):

I have seen exactly the same issue in 16.04, and the last two commands in the answer fixed this for the moment. As the question was closed because the OP didn't answer to comments and/or said it has uninstalled Ubuntu, it should be reopened as I want to take it over (reposting the same would be a duplicate).

  • Please edit your question and add output of lspci -knn | grep Net -A2; lsusb terminal command. – Pilot6 Oct 21 '15 at 14:04

    Is it a HP computer? Have you tried rfkill unblock bluetooth – Jeremy31 Oct 21 '15 at 23:43
  • @Jeremy31 Why don't you make your comment an answer and you can get points when the OP accepts it… – jamadagni Jun 15 '16 at 15:53
  • @jamadagni The asker hasn't signed in since November and never replied. There is a chance that it isn't a HP computer that has loaded a hp-wmi module that caused the block – Jeremy31 Jun 15 '16 at 21:03

    I'm voting to close this question as off-topic because Op has uninstalled Ubuntu and is unavailable to assist in solving problem – Charles Green May 23 '17 at 21:44

If the unblock command doesn't work, try another two commands (which will ask for password):

rfkill unblock bluetooth
systemctl enable bluetooth.service
systemctl start bluetooth.service

  • Apparently the OP has uninstalled Ubuntu, back in 2016 – Charles Green May 23 '17 at 21:41

    @CharlesGreen - many others may edit the question and/or find it useful, no matter what the OP did at some point. – user47206 Mar 15 '18 at 10:28
