  1. 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.

  2. 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.

  3. 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.

  4. 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:

  5. 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

  6. 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.
