Edit 1: After some googling ,I found that I need to buy a Bluetooth adapter to connect my PC to headphone,I bought one (Bluetooth Dongle (Cambridge Silicon Radio, Ltd)) and it plugged to my pc and my bluetooth is "On" but my laptop can not detect my device. After I plugged the bluetooth adpater and run lspci -knn | grep Net -A2; lsusb the result is :

Welcome to Ask Ubuntu! The best way to add additional information to your question is by editing it, with the [edit] button. It is better visible that way, and comments are mainly for secondary, temporary purposes. Comments are removed under a variety of circumstances. Anything important to your question should be in the question itself. — guntbert, Sep 29 '18 at 20:55
your last screen shows bluetooth turned off & on in orange. Try toggling that switch.. — doug, Sep 30 '18 at 16:16
Hi @Menai Ala Eddine, try running dmesg on terminal and see if you find a line where it says "Bluetooth: file_name.hcd on path /lib/... failed to load error -2". If you do, take note of the file name and try searching for it through a search engine. That is a firmware file that needs to be installed for your dongle otherwise. Maybe @Jeremy31 is right about your dongle not been in need of a firmware but dissecting the problem is always helpful and maybe there is a firmware for it. — Rival Consoles, Oct 16 '18 at 08:36

I've struggled for years with bluetooth. The bluetooth stack is very complex and has issues but it gets better year by year.

Here's what I have done and it works great

get yourself a Plugable usb bluetooth adapter (Amazon)
hot plug it, no need to reboot
find and install blueman from the repos (bluez never has worked well for me)
power up your headphones, ready to pair
open blueman, select devices, find your headphones in the list
select setup, choose how you want to connect and click next
after a couple seconds, it should pair
open sound, scroll to find and select your headphones from the list

Note: You'll have to pair again and select in sound after every boot.

The blueman can not find the devices !! – Menai Ala Eddine - Aladdin Oct 07 '18 at 14:38

Then your issues are definately deeper than a simple bluetooth manager problem. Prepare to dig deeper into the system but I'm out, bluetooth stack is too complex for me – Oct 07 '18 at 16:24
@MenaiAlaEddine: In my case I had to to restart both, the device and the scan, multiple times. This worked with a china bluetooth receiver with a cheap USB dongle on an old PC. I didn't manage to get them to work for years now! – hb0 Mar 09 '19 at 00:22
This is not a good solution, first you cannot buy any Bluetooth dongle on Amazon for Ubuntu, it won't work, and second, your solution works only if there are minor problems, if the adapter, like in this question, is not set or recognized, I doubt it works in much cases. – Quidam Jun 08 '20 at 04:44

What is headset ?

For to speak with microphone ? Or for to listen to music ? (I am deaf Ubuntu Linuxer.)

;-)

In Ubuntu often new hardware is recognized, when hardware is at least 4 months to 6 months old (better 1 year old). Concerning music - it can be that there are additional drivers in packages rhythmbox and in amarok and after installation then hardware is recognized - like it was before with some speakers. You might try to install packages with additionally drivers:

sudo apt-get install rhythmbox amarok

And here is a different solution for additionally drivers - specially for Bluetooth and else firmware:

Additional Drivers for Ubuntu 17.10

You might configure this.

After this all perform re-boot.

"often new hardare is recognized, when hardware is at least 4 months to 6 months old", err... no. Not so simple. — Quidam, Jun 08 '20 at 04:45

I have found that a Soundbot dongle works. It reqired a reboot after insertion and was slow to pick up my headphones, but it did finally.

RTL8188EE doesn't have bluetooth

I guess the best answer comes from Linux Mint:

Re: HP Laptop's bluetooth not working

Post by JeremyB » Fri Jun 29, 2018 5:31 am You do not have a bluetooth chipset connected, the Rtl8188ee wifi card doesn't have bluetooth

Additional reference:

The parts list for your notebook indicates that it comes with a Realtek RTL8188EE 802.11bg/n 1x1 WiFi adapter.

That is a single band, non bluetooth wifi adapter.

Here is a review of four Bluetooth USB adapters compatible with Linux for as low as 8 bucks:

It means that my adapter does not compatible with my laptop ! – Menai Ala Eddine - Aladdin Oct 05 '18 at 12:34
The link says that RTL Chipset doesn't have Bluetooth built-in. But I will Google more links when I get home. – WinEunuuchs2Unix Oct 05 '18 at 12:39
@MenaiAlaEddine I've put in another link confirming your adapter does not have bluetooth capability. – WinEunuuchs2Unix Oct 07 '18 at 17:57
I purchasethis adapter but it still the same problem. – Menai Ala Eddine - Aladdin Oct 07 '18 at 20:46
For example to get the adapter pictured in my answer to work you would follow these instructions: https://askubuntu.com/questions/406841/asus-bt400-bluetooth-adapter – WinEunuuchs2Unix Oct 07 '18 at 20:58
It's important that they say "Linux compatible" on the adapter page, before buying. In your Amazon page, but the link you posted above my comment seems to prove it's compatible. People should be very careful about the compatibility, as it brings a lot of problems (from my own experience). – Quidam Jun 08 '20 at 04:47

@Quidam I replaced the single reference with a review of four Linux compatible Bluetooth USB adapters for more choice. – WinEunuuchs2Unix Jun 08 '20 at 10:39
Thank you! I have made the foolish thing to buy a noname stick thinking I would be able to make it work. Poor me. – Quidam Jun 08 '20 at 10:41

I did:

sudo modprobe btusb   ( # add the btusb module to the kernel )
sudo systemctl start bluetooth.service

And it works!

$ sudo systemctl status bluetooth.service
● bluetooth.service - Bluetooth service
   Loaded: loaded (/etc/systemd/system/bluetooth.service; enabled; vendor

I've searched a lot because I got the same problem, Finally I found a code in ubuntu forums that instantly worked:

sudo apt remove bcmwl-kernel-source && sudo apt install git dkms
git clone -b extended https://github.com/lwfinger/rtlwifi_new.git
sudo dkms add ./rtlwifi_new
sudo dkms install rtlwifi-new/0.6

Reboot If you notice weak signal try:

sudo modprobe -r rtl8723de && sleep 5 && sudo modprobe rtl8723de ant_sel=1

and see if it is better, if not do

sudo modprobe -r rtl8723de && sleep 5 && sudo modprobe rtl8723de ant_sel=2

Hope it works for you.

Before executing commands it's better to understand it! This is the repo link https://github.com/lwfinger/rtlwifi_new — wranvaud, Aug 02 '19 at 03:13
