引言
前一篇博文介绍了SLE_UUID_Server和SLE_UUID_Client程序的基本结构，这篇介绍如何进行测试，从而实现两块星闪开发板之间的连接。
服务器的构建
在sdk根目录下（即src目录）打开集成终端台，执行 python build.py -c ws63-liteos-app menuconfig 命令，会出现选择弹窗。menuconfig这种方式是Linux及很多操作系统使用的配置方式。
选择路径"Application/Enable Sample/Enable the Sample of BT/SLE Sample"，如果选择编译server端，选中"support SLE_UUID_SERVER Sample"；如果选择编译client端，选中"support SLE_UUID_CLIENT Sample"。客户端例子和服务器例子是互斥的。BLE例子和SLE例子是互斥的。需要准备两块开发板，选择不同的编译选项，烧录不同的镜像。此次海思的评测提供了两块开发板，一个是单独的开发板，另一个是个套件。可以把单独的开发板当做服务器，而套件用作客户端，因为可以在客户端上采集数据或者显示结果。
按S键保存配置后，此时会提示保存路径，直接确认即可。
保存配置并退出menuconfig后，选择"工程|重新构建"。然后经过漫长的编译和链接就生成了镜像。
在HiSpark Studio工具中点击"工程配置"按钮，选择"程序加载"，就可以将镜像烧写到服务器中。
客户端的构建
客户端的构建和服务器差不多。只是在menuconfig中选中"support SLE_UUID_CLIENT Sample"。
保存配置后，必须选择"工程|重新构建"。如果选择构建是不行的，仍然生成服务器程序。
其他步骤和服务器相同，不赘述了。
测试结果
接下来就是给两块板加电进行测试了。先启动客户端还是服务器是无所谓的，因为客户端一直在查找服务器，如果服务器后启动，客户端会立刻连接上。下面的测试结果是先启动服务器，后启动客户端得到的。
服务器侧
从串口工具看，服务器的日志如下。

其中的"Hello world!" 是我们在第一次测试时加上的，和SLE无关。从日志看，服务器启动后会立即发送广播信息。
一旦客户端连接上服务器，会打印如下信息。

APP|[SYS INFO] mem: used:91108, free:272912; log: drop/all[0/0], at_recv 0.
从日志可以看到客户端的信息。
如果断开客户端，服务器的日志如下。
[Disconnected]

由于手上只有两块开发板，无法测试多客户端的情况。
客户端侧
从串口工具看，客户端的日志如下。

从日志可以看到，客户端和服务器成功配对。有了日志，再看程序的逻辑就容易了。
