惠普笔记本电脑无法使用蓝牙

我已经尝试了几个星期，想为我的 HP 笔记本电脑获取蓝牙驱动程序，它有一个 Realtek RTL8821CE WiFi 和蓝牙 4.2 组合芯片，我尝试了在大量不同论坛上找到的多个驱动程序，但 ubuntu 仍然无法识别蓝牙，它使用该芯片进行 wifi，但说系统中没有蓝牙适配器，设置中需要加密狗。有人能帮忙吗？

编辑：这是我执行 lscpi 的结果

由于。。。导致的结果sudo dmesg | grep -i blue

答案1

作为花时间让过时的 BT 4.2 卡工作的替代方案，您可以以 10 欧元到 15 美元（含运费）的价格订购一张包含 BT 5.1 的 wifi 6 卡，该卡受 ubuntu 21.04 支持，无需进行标准研究。

A working one Wifi6 / BT5.1 card are p.e. a intel AX200
