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 :

When I run hcitool ,it does not detect the adapter (Bus 003 Device 003: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode),and the result is :

Devices:

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.

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.

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.

You can purchase a Bluetooth USB adapter for 20 bucks (CAD) :

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.
