bluetooth working, but not

[highmtns420]

I'm not a Linux heavyweight, but I can usually figure things out (eventually), so please go lightly on me. I have gone through a whole bunch of posts looking for a solution and I have not found what I am looking for, or if I have, I don't recognize it. The blue tooth adapter shows on and gave it a name, but I can't see it in my android discovery list and when I put the android device in discovery mode it doesn't show up on my Mint system.

From the data dump below there were a few things that stood out. The MAC ID for the blue tooth adapter is 00's and that the pacmd and pulseaudio commands said it has some kind of permission issue, but I do have sound.

If there's more syuff needed, please let me know.

From looking at the other posts, here's some of the info that you'll probably want to see:

Click on the bluetooth-icon on the taskbar. Are there devices listed up?

[JeremyB]

Try a complete shutdown/power off and then boot cold. I have the same wifi/BT chipset in my Lenovo and I just used Bluetooth yesterday

Nothing shows up in the devices list and the PC doesn't show up on my devices.

Ok, I did that and now i see on my android the name of the PC, but when I try to pair I get a Could not pair. Please make sure PCname is in pairing mode and try again. I get the same kind of error on my iPad.

I was expecting the PC to come up with a pairing code to put into the devices.

The Bluetooth utility says: Visible as "PCname" name and available for Bluetooth file transfers. Searching for devices.

GOT IT! Now where is the solved button?

This PC is a dual boot system, Windows 10 and Mint on 2 physical hard disks. I don't use the Windows side too much except for scanning, since the HP scanner drivers for Mint don't seem to work too well most of the time.

I swapped over to Windows to see if I had the same issues and found that the Bluetooth adapter had been disabled in Device Manager. I enabled it and tested it with my devices without a problem. I rebooted into Mint and I was able to connect to my devices.

Thanks for all of the suggestions!

No button..
Go back to your first post, hit the edit icon (the pencil) & amend your title by adding the word Solved at the start or end of the original title..
