如何找到東芝衛星c55-896筆記型電腦內建藍牙轉接器

使用Ubuntu一年多了，最近又遇到了老問題。

當我第一次安裝 Ubuntu 時，它在藍牙部分顯示「未找到適配器」。我想買一個無線滑鼠，但找不到解決方法。我可以使用我的連接埠連接外部藍牙，或購買一台新筆記型電腦。

有人可以幫我弄清楚為什麼我的藍牙無法被辨識嗎？

的結果lspci -nnk | grep -iA2 net; lsusb 是：

答案1

問題是該linux-firmware軟體包不包含該模組所需的韌體。它由 表示Patch file not found ar3k/AthrBT_0x31010100.dfu。

這可以透過安裝linux-firmware具有韌體的軟體包來修復。在終端機中運行

wget https://launchpad.net/~hanipouspilot/+archive/ubuntu/rtlwifi/+files/linux-firmware_1.144%2Bar3012_all.deb
sudo dpkg -i linux-firmware*.deb

重新啟動後您的藍牙應該可以工作。

更新我將此韌體發送給linux-firmware維護人員並已添加。遲早它會進入 Ubuntu 儲存庫。
