After upgrading from 14.04 to 15.04, my Bluetooth is not working anymore. I don't have the icon in the taskbar. When I go to Bluetooth in System Settings, it says Bluetooth disabled. Does anyone have an idea of how to fix this? I have attached a few details that could be useful. Thank you in advance.

$ sudo rfkill list all

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

$ sudo service bluetooth status

 bluetooth.service - Bluetooth service
   Loaded: loaded (/lib/systemd/system/bluetooth.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:bluetoothd(8)

$ sudo lsusb; uname -a; lsmod | grep bluetooth; dmesg | grep -i firmware

  • I would blacklist ath3k with echo "blacklist ath3k" | sudo tee /etc/modprobe.d/ath3k.conf Reboot and wait about 1 minute then sudo modprobe ath3k and see if it will work. Are there any files listed with ls /lib/firmware/ar3k

  • @Jeremy31, thank you for your comment, unfortunately, it didn't work. Your command gives: $ ls /lib/firmware/ar3k AthrBT_0x01020001.dfu AthrBT_0x31010000.dfu ramps_0x01020200_40.dfu ramps_0x31010000_40.dfu AthrBT_0x01020200.dfu AthrBT_0x41020000.dfu ramps_0x01020201_26.dfu ramps_0x41020000_40.dfu AthrBT_0x01020201.dfu ramps_0x01020001_26.dfu ramps_0x01020201_40.dfu AthrBT_0x11020000.dfu ramps_0x01020200_26.dfu ramps_0x11020000_40.dfu

  • did you modprobe either ath3k or btusb to get them to load originally? I am going to download 15.04 to see if I have any issues as my bluetooth chipset is the same, even though I am using 14.04 with the 4.0 kernel with no issues

  • @Jeremy31, no, the bluetoot worked fine after installing 14.04 without any extra configuration. Did you manage to see if it works for you in 15.04? Thank you.

  • It did work fine for me on the Live version of 15.04 and was able to pair with my phone and transfer a file. Any reason not to stay with 14.04?
