ubuntu20.04 LTS找不到蓝牙设备_ubuntu蓝牙搜索不到设备

问题

ubuntu中打开蓝牙一直转圈，搜索不到设备。在终端输入

dmesg | grep -i blue

有以下错误信息

Bluetooth: hci0: RTL: unknown IC info, lmp subver 8852, hci rev 000b, hci ver 000b

再输入

lsusb

显示

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 0bda:887b Realtek Semiconductor Corp. Bluetooth Radio

Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

可知是Realtek的蓝牙芯片。
