Hi, i'm unable to make bluetooth working on this system:
dmidecode:

System Information
        Manufacturer: ASUSTeK COMPUTER INC.
        Product Name: PU551JA
        Version: 1.0       
        Serial Number: F1NXWU00954104E     
        UUID: c84c95b0-5cfc-7f44-9728-e8e81147604f
        Wake-up Type: Power Switch
        SKU Number: ASUS-NotebookSKU
        Family: PU

dmesg: http://sprunge.us/8zVB7y
journalctl --boot: http://sprunge.us/NiaK4j
lsmod: http://sprunge.us/9nKwI9
lspci: http://sprunge.us/4feWyy
pacman -Q: http://sprunge.us/qMsW6X (please, don't pay attention to rtl8821au-dkms-git and rtl8821ce-dkms-git; they are from aur and not used by the running kernel; bt did not work even before them.)
pacman -Qm: http://sprunge.us/xr6K8p

From what i understood, the following should be the controller that manages wifi AND bluetooth:
03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8821AE 802.11ac PCIe Wireless Network Adapter

but depsite it being listed by lspci, hwinfo show that bluetooth is actually an usb device:

hwinfo --bluetooth

    Driver Status: btusb is active
    Driver Activation Cmd: "modprobe btusb"
  Config Status: cfg=new, avail=yes, need=no, active=unknown
  Attached to: #13 (Hub)

When i remove and readd btusb, there are the following kernel messages:
after rmmod btusb:

[ 9644.182993] audit: type=1131 audit(1573465572.393:99): pid=1 uid=0 auid=4294967295 ses=4294967295 msg='unit=systemd-rfkill comm="systemd" exe="/usr/lib/systemd/systemd" hostname=? addr=? terminal=? res=success'

...after modprobe btusb:

Well, going further to the actual problem,
node hci0 is created and seems to do some traffic too:

hciconfig hci0

        TX bytes:18123 acl:0 sco:0 commands:108 errors:0

bluetooth service is up and running:

systemctl status bluetooth.service

But:
"bluetoothctl list" returns nothing and
"bluetoothctl power on" returns "No default controller available"

Any idea?
Thanks.

I am experiencing an identical issue with my new ASUS Tuf 15 laptop. Did you find a solution?

archuserbtw · 2021-01-29 18:00:01

I have same problem and I have the same laptop. Did you solve this problem?

You can try to copy rtl8821c_config.bin to rtl8821a_config.bin in the directory /usr/lib/firmware/rtl_bt
https://bugs.debian.org/cgi-bin/bugrepo … =893912#32

Edit: Do you really have the same error message with a missing "rtl8821a_config.bin"? If not, then make a new thread instead of necrobumping an unrelated one.

This is probably the real issue with the latest kernel https://bugzilla.kernel.org/show_bug.cgi?id=210681
