IP及端口准备

本机IP&端口

选择局域网内一个ip及端口，IP一般默认为跟设备同一网关的本机IP，比如192.168.0.72

端口本机则默认绑定37020即可

广播IP及端口

局域网广播IP ：239.255.255.250

端口：37020

报文情况

本机发送

<?xml version="1.0" encoding="utf-8"?>
<Probe>
	<!--随意生成UUID，每次发送报文不一样-->
	<Uuid>8282F1DB-2FA6-4709-B261-3C6B6A48CA17</Uuid>
	<Types>inquiry</Types>
</Probe>

报文回复

回复格式：

注意 ：如果局域网内搜索到几个设备，这里就会放回几条报文，这些报文的uuid是相同的。

流程简述

1. 搜索器 发送搜索 广播报文
2. 设备搜到广播后 回复广播消息
3. 设备同样发送消息至本机搜索器端口
