Dell XPS 13 9350 Ubuntu 23.04

Recently purchased Dell vintage 2015, came with Win10, did not test BT before installing Ubuntu 22.10 and then shortly after installed Ubuntu 23.04. Both installations went well. 22.10 using a USB stick, 23.10 via Wifi. Overwrote the Win OS.

Blue tooth device icon shown at top of screen in Mate desktop. Have two working BT devices, a mouse, and a keyboard. They both work with my Android. But neither device is shown in the BT 'Devices' screen. Clicking 'Search' doesn't show any devices.

lsusb Bus 001 Device 002: ID 0a5c:6412 Broadcom Corp. BCM2045A0

Assuming it's a Broadcom Bluetooth device, this listing doesn't show it.

A rfkill list shows:

2: hci0: Bluetooth Soft blocked: no Hard blocked: no

I've downloaded several driver packages that Dell shows for Linux and tried to install them with no change. The Bluetooth hardware doesn't show any devices.

Anyone know how to deal with this? Thanks.

Edit I have gotten Bluetooth to display a couple BT devices, neither one of them are mine. Don't know where they are coming from. Cannot attach to them and they fade from the Device page. They just sorta show up occasionally, won't let me attach, then fade away.

You can get some information by watching the boot-time logs, as your system discovers it's hardware with: `sudo journalctl -b 0`. Also `service bluetoothd status`. Also `man -k bluetooth`.

Look at the "group" of the Bluetooth device: `ls -l /dev/blue*`. Is that group among your "additional groups"? `id` to see. Please [edit] your question to add whatever information you get. Don't use Add Comment, or you'll classify yourself as "Does Not Follow Instructions (DNFI)", and I'll ignore you. I view DNFIs as unhelpable.

`sudo journalctl -b 0 -t bluetoothd`

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.
