No bluetooth adapter found linux

Не обнаруживается адаптер bluetooth

Купил ноутбук Prestigio 116c, поставил на него сразу же linux mint 19.1 Bluetooth не видит устройства, просто идёт бесконечный поиск устройства. hcitool адаптера не видит:

Модуль нужный подтянулся? Искал на эту тему?

Нужно обновить ядро, например до 4.18 или новее, не знаю, какие у минта есть ядра в репах. Ну и на всякий случай https://4pda.ru/forum/index.php?showtopic=872661&st=720#entry80752304

Обновил ядро до 4.20.5, не помогло. По теме, которую вы скинули, я и устанавливал Linux Mint 19.1, сделал всё по инструкции, но вс ё рвно Bluetooth не работает

Я не знаю название своего bluetooth адаптера, пытался, но по всем командам его не пишет

А точно загружено ядро 4.20.5, а не старое? uname -a

нет, качал с помощью программы ukuu

А Wi-Fi работает? Его не видно в lspci. dmesg

[ 40.790765] Bluetooth: hci0: RTL: rtl: loading rtl_bt/rtl8723bs_fw.bin

И что мне нужно сделать?

Заняться драйверами наверно.

No bluetooth adapters detected

Recently I got a new network card for my netbook (Acer Aspire One AOA150/ZG5) as this one supported bluetooth (the network card previously in my netbook didn’t). I got an Intel Centrino Wireless-N 1030 (as that one supports bluetooth), and when I use lspci it is listed. I’m also able to connect to wifi with it just fine, but for some reason it’s not appearing in my bluetooth adapters (I have installed the bluez package along with bluedevil for KDE and started the bluetooth daemon). I’m not sure what the issue is, and I’ve been looking around on Google trying to find an answer (with no luck so far).

So I was wondering if anyone had any ideas that could help me out.

Re: No bluetooth adapters detected

Good lspci is showing the Bluetooth device.
Next, try running this command. It will display all the local Bluetooth devices that are installed and working.

It doesn’t list anything.

Re: No bluetooth adapters detected

Okay, then it must be a that the driver is not loaded. I guess it ‘could’ be a BIOS thing, but the fact that lspci dose show the bluetooth chipset makes me thing that it is not.

I looked at the kernel config and all the Bluetooth driver are compiled with the default kernel. They are compiled as Modules though, so there is a chance that maybe your driver is just not auto-loading like it should. In any case I’d start googleing and trying to find out which driver your card uses.

Here is the output from my laptop

Bluetooth seems to be on USB for me

Re: No bluetooth adapters detected

What does rfkill list show? My bluetooth has a habit of getting «hard» blocked.

I don’t have the hidp module in my lsmod results but they are otherwise the same as those show above. I also see bluetooth on USB.

rfkill doesn’t show anything (it says command not found)

Also, after installing this new network card I’ve noticed issues with my BIOS (after about 4 seconds it will freeze, and then a few seconds later continue, and then do that again (it doesn’t seem to effect the OS except when booting, as the bootloader will freeze with 2 seconds left and then a few seconds later start booting)). I’m not sure if I can fix that or if I should just put my old card in (I’ve yet to really Google this however, so I’ll be doing that before I replace the card or anything, I just felt it was worth mentioning).

Re: No bluetooth adapters detected

How about you install rfkill then attempt to answer cfr’s question again.

*just did that* idk why I didn’t in the first place (not thinking I guess).

Anyways, the output of rfkill list:

0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

Re: No bluetooth adapters detected

Please use [code ][/code ] tags (w/o) the spaces. It makes stuff much easier to read.

Anyway, it is definitely not the issue I get as rfkill doesn’t see bluetooth at all.

What errors are you getting when you try to start the bluetooth service manually?

By manually do you mean running

(sorry, not really sure :v) When I run those I get no errors or anything (basically it just runs and nothing comes up). However, lately I’ve noticed that when in tty1 an error constantly appears (even when I’m not doing anything it just shows up in the terminal; wont show up in the terminal running in KDE however, only when I’m not in the GUI). The error is:

The numbers inside the square brackets change each time the message displays (the message displays once every 15 or so seconds). I’m not sure if this is related to the bluetooth issue however, as my bluetooth device is connected via mini PCI-e, but the issue only started after installing the new card.

I assume bluetooth is listed in rfkill because my Thinkpad has a hardware switch that turns off all wireless communication devices including bluetooth.

rfkill is a small tool to query the state of the rfkill switches, buttons and subsystem interfaces.

Awe shoot ya, it sounds like your BIOS is having trouble identifying/activating the bluetooth device. I kind of thought it was a long shot that it was a driver problem 1) it is Intel and Intel loves Linux, 2) The Arch Kernel is built with all the bluetooth drivers available.

Three things you could try,

First, see if there is an option in BIOS to do a like «Full Boot» or Not a «Fast Boot»/»Quick Boot»

Second, see if there is a new BIOS available for your laptop.

Three, take out the card, and put it back in. «Maybe» it didn’t seat properly.

If you can get all your money back. Maybe you should, and get a flushmount USB bluetooth adapter instead.

I think I’m going to do that (sending the card back), as I have a USB bluetooth adapter which does work with Arch (I tested it a minute ago). I’ve never actually updated the BIOS so I’m not sure how (but that’s just a Google search away, so I might try that, as this netbook was never made with bluetooth support in mind so that could be the reason it’s not working). I did try disabling quick boot but that didn’t make a difference. I have a feeling if the card wasn’t connected properly wireless wouldn’t work at all either.

Anyways, thanks for the help. Before I send the card back I’m going to look into updating the BIOS so I can see if that’s the issue.

Bluetooth adapter not detected on Linux

I’ve been using Arch Linux for a while and bluetooth has been working without issues. Now, for no explicable reason, Arch doesn’t detect my bluetooth adapters anymore.

I tried doing:
$ sudo systemctl enable bluetooth ,
$ sudo systemctl start bluetooth and
$ sudo systemctl start dbus .

I’ve enabled generic bluetooth drivers:
$ sudo modprobe btusb .

I’ve installed: bluez, bluez-utils-compat and blueman.

$ sudo lsmod | grep bluetooth returns:

$ sudo lspci | grep blue returns nothing.

$ sudo hciconfig returns nothing.

$ sudo hcitool dev returns:

$ sudo dmesg | grep Blue returns:

$ sudo rfkill list returns:

When I open blueman-adapters, it opens but the window doesn’t have any contents:

And when I open blueman-manager, the only functioning buttons are the View and Help menus:

Same symptoms as in the question happend to me on a Dell XPS 13 after installing Wacom software for a Intuos BT S tablet.

Solution for me was disabling Bluetooth in the BIOS, rebooting and enabling it in the BIOS again, as is said in this thread: https://ubuntuforums.org/showthread.php?t=2348005

Are you dual-booting windows? If you are, make sure to disable FastBoot in Windows. This is from Intel Documentation:

About dual-boot with Windows and «fast-boot» enabled If you have a dual-boot machine with a recent version of Windows and start seeing problems during initialization of the WiFi device when booting Linux, the problem could be due to the “fast startup” feature on Windows.

With this feature enabled, Windows don’t really shut down the entire system, but leaves things partially running so you can start the machine faster again. Try to disable this option, on Windows 10 it should be in “Control Panel→Hardware and Sound→Power Options→System Settings”, then disable the “Fast Startup” option in “Shutdown Settings”. This will cause Windows to fully shutdown and may solve the issue.

Had a similar issue and figured out this was the reason.
