I want to send files from my phone to my Laptop and vice versa through Bluetooth. But the Bluetooth on my system doesn't work. When I turn on the Bluetooth switch in System Settings > Bluetooth, nothing happens and also the visibility switch on the right hand side is always disabled.
Output of rfkill list is as follows:
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: no Hard blocked: noOutput of dmesg | grep Blue is as follows:
[ 29.519992] Bluetooth: Core ver 2.21
[ 29.520012] Bluetooth: HCI device and connection manager initialized
[ 29.520016] Bluetooth: HCI socket layer initialized
[ 29.520019] Bluetooth: L2CAP socket layer initialized

[ 54.305799] Bluetooth: BNEP filters: protocol multicast
[ 54.305804] Bluetooth: BNEP socket layer initializedI don't know if the drivers were installed or not and I don't know how to check it either.
Any idea what the issue is?

My ubuntu 16.04 couldn't find the Bluetooth devices, even though the devices's pairing switch was on.
Ubuntu 16.04 Bluetooth Speakers
In short, I tried following process.
sudo nano /etc/bluetooth/main.conf- Change
#AutoEnable=falsetoAutoEnable=true(at the bottom of the file, by default) systemctl restart bluetooth.service
Then, my Ubuntu machine was able to find the Bluetooth devices!
5After so many attempts to solve this issue the following commands did it for me.
rfkill block bluetoothThen I do the following
rfkill unblock bluetoothI tried all the above but it didn't work for me, as the bt is not blocked but disabled and can't be turned on.
but i found this
sudo modprobe -r btusb
sudo modprobe btusband i got my disabled bluetooth come to life and pair with my headphones!
4My Bluetooth tended to "fall out", and I had to to do a reebot. But this solved it:
sudo service bluetooth restart(easier than a reboot!)
1I had the same problem. In my case I think it was a bug of my old installed version of unity control center, or some missing dependencies. Resolved easily updating unity-control-center:
sudo apt-get install unity-control-centerHope it may help.
1For me after two days of searching without any luck. I burned an image of Ubuntu on a USB stick, entered Try mode. Tested Bluetooth and it works and could find devices and pair.
Then I installed a new image of ubuntu on my HardDisk tried to install all of programs installed on old installation till that point when I found that Bluetooth stop working
I figured that I installed a tool called TLP for power management, When I removed it via apt remove tlp and reboot, Bluetooth worked and could find other devices!
Maybe TLP needs to be configured someway to work good with Bluetooth
I hope this may help you
Update:
I've installed the latest version of TLP and now Bluetooth working without any problems.
TLP releases on Gihub: here
Download the latest release uncompress
cd TLP-1.0
# use checkinstall so that you can remove it anytime
sudo checkinstallUse PPA to get latest release
sudo add-apt-repository ppa:linrunner/tlp
sudo apt update
sudo apt install tlpAnd reboot.
3Try this,
$ rfkill list
0: hp-wifi: Wireless LAN Soft blocked: no Hard blocked: no
1: hp-bluetooth: Bluetooth Soft blocked: yes Hard blocked: no
2: phy0: Wireless LAN Soft blocked: no Hard blocked: noSo from the list Bluetooth is blocked by rfkill, no wonder I cannot connect in the GUI.
$ rfkill unblock bluetooth
$ rfkill list
0: hp-wifi: Wireless LAN Soft blocked: no Hard blocked: no
1: hp-bluetooth: Bluetooth Soft blocked: no Hard blocked: no
2: phy0: Wireless LAN Soft blocked: no Hard blocked: no
3: hci0: Bluetooth Soft blocked: yes Hard blocked: noAfter the unblock command I get a new device hci0 that is Soft blocked, but the hp-bluetooth device is unblocked and it doesn’t work from the GUI still.
$ hciconfig hci0 up
Can't init device hci0: Operation not permitted (1)
$ sudo hciconfig hci0 up
[sudo] password for karibe:
Can't init device hci0: Operation not possible due to RF-kill (132)
rfkill unblock bluetooth hci0
rfkill list
0: hp-wifi: Wireless LAN Soft blocked: no Hard blocked: no
1: hp-bluetooth: Bluetooth Soft blocked: no Hard blocked: no
2: phy0: Wireless LAN Soft blocked: no Hard blocked: no
3: hci0: Bluetooth Soft blocked: no Hard blocked: noAfter this everything is working as expected. I do not know why rfkill is from time to time blocking bluetooth, but now I know how to unblock when I need to use it, and block when I don’t need to use it.
I always use this this to restart everything:
:~# rfkill block bluetooth; rfkill list; /etc/init.d/bluetooth restart;\
/etc/init.d/bluetooth status;\
modprobe -r btusb; modprobe btusb;\
/etc/init.d/bluetooth restart; /etc/init.d/bluetooth statusAfter some time with Bluetooth upload from phone not working on my laptop, I found that installing blueman-applet (sudo apt install blueman) and adding 'trust' for the device and then specifying to accept uploaded files fixed my problem. I don't really know why there are two Bluetooth icons in my taskbar now -- but the blueman-applet seems to provide a lot more options than the standard Gnome/Ubuntu applet.
The extra applet menu:
Context menu of the Devices list allows 'trust' of device:
Local Services dialog allows Bluetooth to accept uploaded files:
EDIT: further digging shows that there is a 'Personal File Sharing' dialog recommended by Ubuntu that is supposed to support this functionality directly without blueman-applet. But it didn't work for me.
Note: this answer is for Debian only!
In my case the Bluetooth device was not detected. In my case it was part of the Qualcomm Atheros hardware:
$ lspci -knn | grep Net -A2
03:00.0 Network controller [0280]: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter [168c:0036] (rev 01) Subsystem: Hewlett-Packard Company QCA9565 / AR9565 Wireless Network Adapter [103c:217f] Kernel driver in use: ath9k Kernel modules: ath9kInstalling the proprietary/non-free firmware and rebooting helped.
sudo apt-get install aptitude
sudo aptitude install firmware-atheros
