问题:
Ubuntu 20.04 无法检测到蓝牙卡,我认为这可能是因为使用了错误的驱动程序。我有一台 HP Spectre 360 笔记本电脑,它使用 Intel® Wi-Fi 6 AX201 网卡(它集成了蓝牙)。
分析
消息命令确实检测到了该设备(以及 Windows 中的设备管理器)
[ 2.403441] iwlwifi 0000:00:14.3: Detected Intel(R) Wi-Fi 6 AX201 160MHz, REV=0x354
然而串行通信命令检测到不同的英特尔网络设备(使用不同的 iwlwifi 驱动程序版本)0:14.3 Network controller [0280]: Intel Corporation Wireless-AC 9462 [8086:02f0]
