dmesg看不出蓝牙型号。。

蓝牙型号是什么？是RTL8821CU网卡集成的蓝牙吗？

lspci -v

或者

lsusb

能看到蓝牙吗？

RTL8723BE网卡集成的蓝牙，dmesg | grep bluetooth显示：

下载这个文件 https://github.com/armbian/firmw ... config.bin?raw=true

然后放到

sudo mkdir -p /lib/firmware/rtl_bt

sudo cp rtl8723b_config.bin /lib/firmware/rtl_bt

然后重启

还不行的话再发一下dmesg | grep bluetooth

是的，是RTL8821CU集成的蓝牙，win10下可用。linux下始终不能驱动。

8821cu目前有这个问题，已经debug。
目前是换个驱动和固件：
1.驱动用的：https://github.com/rainbow-cnay/rtl8821cu-nvidia-jetson-nano
2.固件下载这个：
cd /lib/firmware/rtl_bt
sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/rtl_bt/rtl8821c_config.bin
sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/rtl_bt/rtl8821c_fw.bin
sudo update-initramfs -u
reboot
驱动和固件不匹配导致的。测试Pass
