4) 然后通过 sudo ifconfig 命令可以看到 RTL8723BU WIFI 的设备节点，WIFI 的连接和测试方法请参看 WIFI 连接测试一节，这里不再赘述
orangepi@orangepi:~$ sudo ifconfig wlx0013eff458ae
wlx0013eff458ae: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500

- RX errors 0 dropped 0 overruns 0 frame 0
- TX packets 0 bytes 0 (0.0 B)
- TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
|
5) 然后通过 hciconfig 命令可以看到 USB 的蓝牙设备
orangepi@orangepi:~$ sudo apt update && sudo apt install bluez
orangepi@orangepi:~$ hciconfig
hci0: Type: Primary Bus: USB

6) 在桌面中也可以看到出现了蓝牙图标，此时蓝牙还未打开，所以会显示一个红色的 x
7) 点击 Turn Bluetooth On 可以打开蓝牙
8) 打开蓝牙后的显示如下所示
9) 蓝牙的测试方法请参看 蓝牙使用方法一节，这里不再赘述
2、RTL8811 测试
1) 首先将 RTL8811 无线网卡模块插入开发板的 USB 接口中

3、RTL8821CU 测试
1) 首先将 rtl8821cu 无线网卡模块插入开发板的 usb 接口中
2) 然后使用 lsusb 命令就可以看到 rtl8821cu usb wifi 模块的设备信息，请确保 USB模块没有处于 Driver CDROM Mode
|
orangepi@orangepi:~$ lsusb | grep "Realtek"
Bus 002 Device 003: ID 0bda:c820 Realtek Semiconductor Corp. 802.11ac NIC
|
|
orangepi@orangepi:~$ lsusb | grep "Realtek"
Bus 002 Device 002: ID 0bda:1a2b Realtek Semiconductor Corp. RTL8188GU 802.11n WLAN Adapter (Driver CDROM Mode)
如果 lsusb 命令看到的 USB WIFI 模块处于 Driver CDROM Mode，请重新拔插下 USB WIFI 模块。如果还不行，请手动执行下面的命令切换下模式：
orangepi@orangepi:~$ sudo usb_modeswitch -KW -v 0bda -p 1a2b
|
3) linux 系统会自动加载 rtl8821cu 蓝牙和 wifi 相关的内核模块，通过 lsmod 命令可以看到下面内核模块已自动加载
