不能让蓝牙在惠普笔记本电脑上工作

Question

几个星期以来，我一直在尝试为我的惠普笔记本电脑安装蓝牙驱动程序，它有一个Realtek RTL8821CE WiFi和蓝牙4.2 Combo芯片，我尝试了在大量不同论坛上找到的多个驱动程序，但是ubuntu仍然不识别蓝牙，它使用该芯片用于wifi，但是它说系统中没有蓝牙适配器，并且在设置中需要一个dongle。有人能帮忙吗？

作为替代，花你的时间让过时的BT 4.2卡工作，你可以订购10欧元至15美元，包括。传送一张wifi 6卡。BT 5.1，由BT 21.04支持，没有标准的研究。

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