I could not get the slider to work. So I bought a Bluetooth thing and plugged it in to the USB.
The slider now moves on or off, but nothing happens. Bluetooth is still off.

What information can I post for help? What commands should I run?

Thank you for your time.
 


You will need to furnish more info......which OS and which version of that os....is it updated completely etc
 
Try this

sudo apt-get install pulseaudio-module-bluetooth
reboot your system.

sudo systemctl start bluetooth.service
now open the GUI utility for the Bluetooth and make sure Bluetooth is set on "on"
in the terminal type
bluetoothctl
make sure that the command
actually shows something similar to
bluetooth]# show
Controller 20:16:D8:95:E5:03 (public)
Name: debian
Alias: debian
Class: 0x007c010c
Powered: yes
Discoverable: no
DiscoverableTimeout: 0x000000b4
Pairable: yes

Does it work?
 
I still could not get this ti work after...
sudo systemctl start bluetooth.service

So I did more reading and tried pipewire instead and that didn't work either....
So I did more searching and found multiple references to install ibluez* and blueman so I did that.
Then I tried sudo systemctl start bluetooth.service again and it worked.

I did blueroothctl and it said agent registered. I did show and it said No default controller available
Yet still no Bluetooth it still off even though slider is on
 
it was a typo bluez*

I really don't want to do a complete re-install to see if it will fix the issue. But I do not know what else to do. As I have tried what seems to be the most popular fix above.

Anyone?

Thank you for you time.

That is taken with a dongle inserted in a usb port

and using the command from above....
brian@brian-desktop:~$ inxi -Eaz
Bluetooth:
Device-1: Cambridge Silicon Radio Bluetooth Dongle (HCI mode) type: USB
driver: btusb v: 0.8 bus-ID: 1-2:7 chip-ID: 0a12:0001 class-ID: e001

brian@brian-desktop:~$

Not sure if this helpful or not.

Also in software manager, there is: Bluez-obexd & Bluez-cups (probably printer related)... which are also installed
 
inxi -Eaz

Bluetooth:
Device-1: TP-Link UB500 Adapter type: USB driver: btusb v: 0.8

Need to check for missing firmware now
lsusb; dmesg | egrep -i 'blue|firm'
or you can run
sudo dmesg | grep -i bluetooth
and post back the results - if it is missing firmware it should show something like
RTL: firmware file rtl_bt/rtl8761b_fw.bin not found
