[Solved] Bluetooth not able to make work. MPOW BH519A

Rakowu Asks: Bluetooth not able to make work. MPOW BH519A
I am trying to get my MPOW BH519A Bluetooth adapter to work. There are similar posts, including one on this adapter. Unfortunately, I tried them all and nothing helped. I have already tested some commands like:

  • sudo apt install blueman
  • sudo make install INTERFACE=all (MPOW Linux Driver download, inside of the folder ran this command)
  • sudo mv -v ~/Downloads/rtl8761b_config /usr/lib/firmware/rtl_bt/rtl8761b_config.bin
  • snap install bluez4
  • snap install bluez
  • sudo apt install bluez bluez-obexd
  • sudo apt-get install bluez-utils libopemnobex1
  • sudo apt reinstall bluez
  • sudo blueman-manager

Im not even able to make the led run. I managed to set the control to on, but it says “no bluetooth adapter found”. After several attempts with different commands, I was not even able to set the control to on.

I have the feeling that I may have duplications or simply overlook something essential since I am a complete Ubuntu beginner.

Here are a number of ouputs. Unfortunately I don’t know in detail which information is helpful for you.
