I cannot seem to get the bluetooth hardware to work with Ubuntu. I can get a USB dongle working, but I'm sure the laptop has internal bluetooth hardware.

Update:

I have halfway succeeded in getting the bluetooth to work by doing step 12 in the list directly below. I actually did this on Lubuntu 16.04, but will test it with Ubuntu 16.04 as well. I successully paired a bluetooth mouse, and am able to use it. However, it is laggy, but not to the point of being unusable. I am also able to send and receive files to my LG G4 via bluetooth. I am, however, not able to pair to bluetooth speakers. I tried pairing to two speakers of different brands, and it appears to connect briefly for a second and then disconnects.

Update:

I have also just gotten the bluetooth speakers to work on Lubuntu 16.04 by doing step 13 directly below. I also was able to get it working on a freshly installed Ubuntu 16.04. I posted the steps to do it as an answer below.

What I have tried:

1) Okay, so I have the Blueman Bluetooth Manager/BlueZ installed.

2) I know the bluetooth programs are functional because I can plug in a bluetooth usb dongle and eveything works how it should with the dongle. I am able to connect bluetooth devices with the dongle.

3) I also know that the laptop itself has bluetooth hardware apart from the dongle I plugged in, because I can unplug the dongle and boot into Windows 10, and bluetooth functions on the Windows 10 OS.

4) I left bluetooth enabled on Windows as well.

5) There are no hard buttons (that I can find) on my laptop to enable or disable bluetooth.

6) In UEFI, bluetooth is enabled.

7) In UEFI, Secure Boot is disabled.

8) I have tried$ rfkill unblock bluetoothfrom this post to no avail.

9) I have also tried $ sudo hciconfig hci0 reset which sadly didn't work and gives the output "Can't get device info: No such device"

10) I have also tried $ sudo chmod +x /usr/sbin/bluetoothd and sudo service bluetooth restart from this post.

11) I have tried reinstalling software as suggested in this post:

$ sudo apt-get install bluetooth blueman bluez-hcidump bluewho python-bluez  bluez-tools

12) I was able to get bluetooth partially working on Lubuntu 16.04 by following the steps from this post by Klip. I had to modify the steps slightly to get it working though, so I will post my modified steps.

  1. mkdir ~/tmp
  2. cd ~/tmp
  3. git clone https://github.com/alinefr/rtbth.git
  4. cd rtbth
  5. make
  6. sudo make install
  7. sudo mkdir /usr/src/rtbth-3.9.3
  8. sudo cp -r ~/tmp/rtbth/* /usr/src/rtbth-3.9.3
  9. sudo dkms install rtbth/3.9.3
  10. sudo nano /etc/modules
  11. Add rtbth to the end of the file, press ctrl+o then enter to save the file, and then press ctrl+x to exit.
  12. Reboot

13) I was able to successfully pair and output audio to my bluetooth speakers on Lubuntu 16.04 by following the steps from this post by user631559. Here they are below:

  1. sudo apt-get install pulseaudio-module-bluetooth
  2. pactl load-module module-bluetooth-discover

Other information:

-When I open the default bluetooth GUI in System Settings... I am able to toggle the on/off switch. -Whether the bluetooth is toggled on or off, underneath it, in the box that displays the devices you would be connected to, it says, "Bluetooth is disabled".
-When I try to run Bluetooth Manager it gives this error message:

Connection to BlueZ failed  
Bluez daemon is not running, blueman-manager cannot continue.
This probably means that there were no Bluetooth adapters detected or Bluetooth daemon was not started.

To get bluetooth to work on Ubuntu 16.04 with a Ralink-3290 driver do the following.

  1. sudo apt-get update

  2. sudo apt-get install git

  3. sudo apt-get install dkms

  4. mkdir ~/tmp

  5. cd ~/tmp

  6. git clone https://github.com/alinefr/rtbth.git

  7. cd rtbth

  8. make

  9. sudo make install

  10. sudo mkdir /usr/src/rtbth-3.9.3

  11. sudo cp -r ~/tmp/rtbth/* /usr/src/rtbth-3.9.3

  12. sudo dkms install rtbth/3.9.3

  13. sudo nano /etc/modules

  14. Add rtbth to the end of the file, press ctrl+o then enter to save the file, and then press ctrl+x to exit.

  15. Reboot

It should be working now! If not try running sudo dkms install rtbth/3.9.3 another time and rebooting again.

To get it working in Lubuntu 16.04 I had to install pavucontrol to get audio working at all, and then I had to install pulseaudio-module-bluetooth to get the bluetooth speakers working.

  1. sudo apt-get install pavucontrol

  2. sudo apt-get install pulseaudio-module-bluetooth

  3. pactl load-module module-bluetooth-discover
