藍牙在 NUC11 上的 Debian 11 下不起作用
所以我在 NUC11PAHi5 上安裝了 Debian 11(Bullseye)。到目前為止,一切似乎都執行良好,但是今天早上當我嘗試配對一些耳機時,我發現藍牙實際上無法正常工作。
在設置中,當我轉到藍牙時,它顯示為關閉。我可以打開它,但開關是所有的變化。如果我轉到不同的設置窗格並返回,藍牙將再次關閉。
uname -a
:Linux NUCTUX 5.10.0-8-amd64 #1 SMP Debian 5.10.46-4 (2021-08-03) x86_64 GNU/Linux
當我執行時
sudo dmesg | grep tooth
,我得到:[ 3.787615] Bluetooth: Core ver 2.22 [ 3.787629] Bluetooth: HCI device and connection manager initialized [ 3.787632] Bluetooth: HCI socket layer initialized [ 3.787634] Bluetooth: L2CAP socket layer initialized [ 3.787636] Bluetooth: SCO socket layer initialized [ 3.794108] Bluetooth: hci0: Bootloader revision 0.4 build 0 week 30 2018 [ 3.795110] Bluetooth: hci0: Device revision is 2 [ 3.795111] Bluetooth: hci0: Secure boot is enabled [ 3.795112] Bluetooth: hci0: OTP lock is enabled [ 3.795112] Bluetooth: hci0: API lock is enabled [ 3.795113] Bluetooth: hci0: Debug lock is disabled [ 3.795114] Bluetooth: hci0: Minimum firmware build 1 week 10 2014 [ 3.795136] bluetooth hci0: firmware: failed to load intel/ibt-19-0-4.sfi (-2) [ 3.795176] bluetooth hci0: Direct firmware load for intel/ibt-19-0-4.sfi failed with error -2 [ 3.795178] Bluetooth: hci0: Failed to load Intel firmware file (-2) [ 5.670228] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 5.670229] Bluetooth: BNEP filters: protocol multicast [ 5.670232] Bluetooth: BNEP socket layer initialized
where
failed to load intel/ibt-19-0-4.sfi (-2)
似乎是我的問題的潛在原因,但搜尋該消息幾乎沒有結果。我最初在 UEFI 管理器中禁用了 wifi,因為我沒有使用它,但打開它沒有任何區別。
有人遇到過這個,或者有任何指示嗎?提前致謝!
firmware: failed to load intel/ibt-19-0-4.sfi
是它不起作用的確切原因。您需要
