Found a Solution here: Bluetooth service failed to set mode

My Bluetooth seems to be running but it will not show the devices in pairing mode. I have attached the status below. Thank you.

Where did kernel 5.15 come from? What happens if you use the proper standard kernel for 21.10?

I had a problem with my motherboard where the wifi didn't work. (msi pro z690-a) I had the same problem with windows until I updated the drivers. I read on here that the newer kernel would support my mobo out of the box and it did. I was on the standard kernel before I switched with no network connections working. switching to 5.15 got the wifi working right away and then the bluetooth followed with some tweaking. I also had to issues with the nvidia graphics card not working right with the new kernel but I just had to switch the nvidia x to a newer version as well.

You may also have a BIOS problem. `sudo dmidecode -s bios-version`.

Bios 1.00, it does say there is some sort of bios bug on startup screen. Its not affecting my usage though at this point. Should I be worried?

Tell me the EXACT make/model # of your computer or motherboard, and I'll take a look.

Jan 31 10:58:26 NeoNeb-Ubuntu bluetoothd[921]: Failed to set mode: Blocked through rfkill (0x12)

Source: Bluetooth service failed to set mode

sudo rfkill unblock bluetooth
sudo systemctl stop bluetooth
sudo systemctl start bluetooth
sudo systemctl status bluetooth

BIOS

MSI Pro Z690-A WIFI DDR4

You have BIOS 1.00 dated 9/15/2021. There's a newer BIOS available, version 1.26 (beta) dated 1/25/2022. There's a slightly older version 1.1 dated 12/13/2021. I'd recommend version 1.1. Either can be downloaded here.

How to update the BIOS is PDF or YouTube.

Note: Confirm that I have the correct web page for your model #

Note: Have good backups before updating the BIOS

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
