'''1、RTL8723BU 测试1.RTL8723BU test'''<br><br>1) 首先将 First insert the RTL8723BU 无线网卡模块插入开发板的 wireless network card module into the USB 接口中interface of the development board<br><br>2) 然后linux 系统会自动加载RTL8723BU 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Then the linux system will automatically load the RTL8723BU bluetooth and WIFI-related kernel modules, through the lsmod command, you can see that the following kernel modules have been automatically loaded<br>

3) 通过 Through the dmesg 命令可以看到 command, you can see the loading information of the RTL8723BU 模块的加载信息module<br>

4) 然后通过 Then you can see the device node of RTL8723BU WIFI through the '''sudo ifconfig''' 命令可以看到 RTL8723BU command. For the connection and test method of WIFI 的设备节点，WIFI 的连接和测试方法请参看 <span style="color:#0066CC;">[[Orange Pi 5 detail#查询 , please refer to '''the section of WIFI 连接测试 | WIFI 连接测试]]</span>一节，这里不再赘述connection test''', which will not be repeated here<br>

TX packets 0 bytes 0 (0.0 B)<br>TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0<br>

5) 然后通过 Then you can see the USB Bluetooth device through the '''hciconfig''' 命令可以看到 USB 的蓝牙设备command<br>

TX bytes:23307 acl:0 sco:0 commands:125 errors:0<br>

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 You can also see the bluetooth icon on the desktop. At this time, the bluetooth is not turned on, so a red '''<span style="color:#FF0000">x</span>'''will be displayed<br><br>

7) 点击 Click '''Turn Bluetooth On''' 可以打开蓝牙to turn on Bluetooth<br><br>

8) 打开蓝牙后的显示如下所示The display after turning on Bluetooth is as follows<br><br>
