[Hardware] Bluetooth - cannot make it work

#1 Post by kajasie »

I try to make bluetooth work but I haven't managed to. The machine state is as follows:

Code: Select all

Operating System: Debian GNU/Linux 11
KDE Plasma Version: 5.20.5
KDE Frameworks Version: 5.78.0
Qt Version: 5.15.2
Kernel Version: 5.10.0-20-amd64
OS Type: 64-bit
Processors: 4 × Intel® Core™ i3-4005U CPU @ 1.70GHz
Memory: 3.8 GiB of RAM
Graphics Processor: Mesa DRI Intel® HD Graphics 4400
dmesg output:

Code: Select all

[  193.484328] Bluetooth: Core ver 2.22
[  193.484381] Bluetooth: HCI device and connection manager initialized

[  193.484399] Bluetooth: SCO socket layer initialized
[  193.701949] Bluetooth: BNEP (Ethernet Emulation) ver 1.3
[  193.701953] Bluetooth: BNEP filters: protocol multicast
[  193.701961] Bluetooth: BNEP socket layer initialized
lspci output:

[code]02:00.1 Bluetooth: Ralink corp. RT3290 Bluetoot
[/code]

lsmod output:

Code: Select all

bnep                   28672  2
bluetooth             753664  7 bnep
rfkill list output:

Code: Select all

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

Code: Select all

systemctl status bluetooth.service
● bluetooth.service - Bluetooth service
     Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor>
     Active: active (running) since Sun 2023-01-22 12:08:49 CET; 26min ago
       Docs: man:bluetoothd(8)
   Main PID: 1770 (bluetoothd)
     Status: "Running"
      Tasks: 1 (limit: 4553)
     Memory: 1.3M
        CPU: 41ms
     CGroup: /system.slice/bluetooth.service
             └─1770 /usr/libexec/bluetooth/bluetoothd
System settings on kde desktop says that BT is disabled and pressing Enable button doesn't do anything nor I can search any BT devices around.
I would be grateful for any hints.

Please install inxi and show

Code: Select all

inxi -E
You probably need to install firmware-ralink for that device. Hopefully just installing that will get it working.

The inxi command will show if the kernel module is present. If it shows:

Code: Select all

Bluetooth:
  Device-1: Ralink RT3290 Bluetooth driver: N/A
It means device is detected but no driver module is present. Module is available here - https://github.com/loimu/rtbth-dkms .

The output of inxi -E

Code: Select all

Bluetooth:
  Message: No Bluetooth data was found. 
but output of inxi -N is OK though this is the same device I think:

Code: Select all

  Device-2: Ralink RT3290 Wireless 802.11n 1T/1R PCIe driver: rt2800pci 
lspci:

Code: Select all

02:00.1 Bluetooth: Ralink corp. RT3290 Bluetooth

I got and made the driver rbth.ko. What should I do next? modprobe rbth says:

Code: Select all

[code]Module rtbth not found in directory /lib/modules/5.10.0-20-amd64
[/code]
What should I copy there?

I am running Debian 11 on 4 laptops. I use Bluetuith, no problems.
Just google "Bluetuith".
