No Bluetooth Adapter found Ubuntu 19.04

My Bluetooth adapter suddenly disappeared, and I have been trying to fix it but no luck.

I have tried to enable or start it again but its status is still inactive.

~$   sudo systemctl enable bluetooth Synchronizing state of bluetooth.service with SysV service script with /lib/systemd/systemd-sysv-install. Executing: /lib/systemd/systemd-sysv-install enable bluetooth  ~$   sudo systemctl status bluetooth ‚óŹ bluetooth.service - Bluetooth service   Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset: enabled)   Active: inactive (dead)     Docs: man:bluetoothd(8)  Oct 14 00:33:19 lau-desktop systemd[1]: Condition check resulted in Bluetooth service being skipped.

Oct 14 00:34:43 lau-desktop systemd[1]: Condition check resulted in Bluetooth service being skipped. Oct 14 00:37:36 lau-desktop systemd[1]: Condition check resulted in Bluetooth service being skipped. 

What else can I do?

Bluetooth Randomly Stopped

I’m using a Developer, Ubuntu shipped with it pre-installed Dell Precision 7530. Today while working, my bluetooth speakers beeped indicating they disconnected, I went to reconnect and in the bluetooth settings it’s saying “No Bluetooth Found. Plug in a dongle to use Bluetooth.” – except I’ve been using bluetooth for the entire 6 months I’ve owned the laptop so there absolutely is a dongle. I’ve restarted the computer several times, including fully off/on, and nothing. I’m at a loss. Any suggestions here?

I’ve seen other chats about bluetooth not working but they tend to be people that upgraded recently etc. – I haven’t. It just STOPPED after working fine and flawlessly.

I’m on Ubuntu 18.04 LTS.

How to solve “256966901 Bluetooth: hclo: unexpected event for opcode 0xfc2f” Message during Boot in Ubuntu 19.04?

Every time I boot into Ubuntu 19.04 it shows this message. This doesn’t cause any problem. The system Boots Up correctly and Bluetooth is also functioning properly. But why this is happening I don’t know. And this is annoying..

XPS 13 9350 Bluetooth reception poor

This is potentially an hardware/antenna issue but just on the off-chance that someone knows anything about it being an issue on Ubuntu Linux, here’s my question anyway.

Bluetooth reception on my XPS 13 (9350) seems extremely poor under Ubuntu Linux 19.10 (I don’t know about Windows – haven’t got it).

My bluetooth keyboard literally needs to be within 2 cm of the laptop or it won’t work. Sometimes I even have to lift the keyboard to send the keystrokes I just made. Needless to say, it’s impossible to work with this.

I’ve already tried copying the broadcom firmware from https://github.com/winterheart/broadcom-bt-firmware/blob/master/brcm/BCM4350C5-0a5c-6412.hcd (this corresponded to the ID from lsusb) to /lib/firmware/brcm/ and rebooted but this didn’t help.

The keyboard works fine with other computers (Windows).

Bluetooth headset SONY cannot connect – nothing worked

I cannot connect my bluetooth Sony headset. I’ve read many similar threads so I’ve already done: 1. Blueman installed 2. in /etc/bluetooth/main.conf I added lines:

AutoEnable=true Disable=Headset Enable=Source 

BT claims that headset is connected fine but it is not listed on output devices list. Headset does not reacts (no “bluetooth connected” information”). I’ve connected that once before but it didn’t want to set the A2DP profile so I dispaired it and I cannot connect it properly again. What have I missed?

What is wrong with my bluetooth?

Recently I notice this problem when I try to turn on my computer’s bluetooth it seems that option disappear:

enter image description here

Also I tried to check the Bluetootn Settings: enter image description here

What should I do? I need to cenect a wireless bluetooth speakers. EDIT

I can repair the turn off/on issue. It was because the bluetooth was blocked so I just run into the terminal:

sudo rfkill unblock bluetooth 

But now I can not connect with any devices:

Bluetooth headphones crashing driver

My bluetooth settings are working fine with any kind of phone. I’ve recently got a set of Ryhodi bluetooth headset and my driver goes haywire.

I’ve uninstalled all kind of bluetooth services and audio service (huge mistake, took me 1.5h to recover all the settings back into my linux) without success.

After my sound and bluetooth went back live I’ve decided to switch on this specific set of headphones (https://www.amazon.co.uk/gp/product/B07PCRLTRK/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1) and the problem showed up again.

In short what happens is that when I switch the Heaphones ON it tries to pair with my PC, my bluetooth keeps on losing it’s will to live and every so often (every 5-15 sec) and goes into “Please insert dongle to use Bluetooth”.

I’ve tried all of the google wisdom to manipulate pulsedaudio.serive, bluetooth.service, pavucontrol.

Any ideas where to go further? Is this cheaper-end bluetooth speakers not suitable for Linux control?

Thanks, Tom
