−	[[~~Category~~:~~Hollong协议分析器~~]]	+	== Hollong BLE Sniffer简介 ==
		+	Hollong BLE Sniffer是纬图推出的一款BLE抓包工具，它借鉴了市面上现存的抓包工具优点，并弥补了这些抓包工具的不足，使用全新的设计思路，实现百分百无遗漏抓取BLE数据。同时根据抓包使用习惯，通过选择指定的BLE设备进行定向抓取数据，最后利用强大的协议分析软件Wireshark实现对BLE数据各个协议层进行非常友好的解析。利用该工具可以非常方便的看到BLE传输的数据，在BLE开发中能快速定位问题、分析问题并解决问题，同时也是初学者学习BLE协议不可缺少的工具。
		+	目前市面上常见BLE抓包工具对比：
		+	{\| class="wikitable"
		+	\|-
		+	! 工具名称 !! 数据输出方式 !! 抓包频道 !! 协议分析软件
		+	\|-
		+	\| Hollong BLE Sniffer \|\| USB \|\| 全频道 \|\| 支持最新版本Wireshark
		+	\|-
		+	\| nRF51822 USBDongle \|\| 串口转USB \|\| 3个频道中的一个 \|\| 不支持新版本Wireshark
		+	\|-
		+	\| CC2540 USB Dongle \|\| USB \|\| 3个频道中的一个 \|\| Packet sniffer
		+	\|}
		+	根据上表可知，市面上常见的BLE抓包工具有个致命的缺点，就是只能抓取BLE广播频道3个中的某一个，也就是说，其抓包概率是1/3，大家都知道，BLE设备一般同时在3个频道广播，但是是在这3个频道中的某一个频道建立连接，当然这个连接频道也是不固定的，这就导致它们这种抓包方式抓取连接数据的概率大大低于1/3，而Hollong BLE Sniffer采用新的设计思路，可以同时抓取3个频道的数据，所以不管你BLE设备是在什么频道进行广播或者连接，Hollong BLE Sniffer都能100%抓到数据！
		+	Packet sniffer软件是TI自己出的软件，其数据解析并不是很详细，所以我们使用Wireshark作为数据解析软件，Wireshark具有强大的数据过滤功能，我们可以通过设置过滤器，让它只显示我们关心的数据，nRF51822 USBDongle虽然也是用Wireshark解析数据，但是它支持的Wireshark版本较低，对BLE上层协议支持较少，所以在数据解析方面还是差一些。
		+
		+	== 软件安装 ==
		+	要正常使用Hollong BLE Sniffer抓包工具，需要安装USB驱动程序，Hollong BLE Sniffer软件，Wireshark软件，为了方便用户使用，我们将这3个步骤合并成了一个步骤，也就是说只需要安装我们提供的软件安装包即可。
		+	==== 软件下载 ====
		+	官网链接：www.viewtool.com
		+	软件下载链接：www.viewtool.com/product/BLE-Sniffer
		+
		+	==== 软件安装 ====
		+	双击Hollong_BLE_Sniffer_Setup_v1.0.0.exe文件启动软件安装，选择安装向导语言，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.1.png]]
		+	选择好语言之后点击“确定”，进入下一步，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.2.png]]
		+	直接点击“下一步”，在弹出的对话框中选择软件安装目录，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.3.png]]
		+	设置好软件安装目录之后，点击“下一步”，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.4.png]]
		+	直接点击“下一步”，然后在弹出的对话框中选择是否在桌面生成快捷方式，然后再点击“下一步”，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.5.png]]
		+	点击“下一步”确定开始软件安装，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.6.png]]
		+	点击“安装”开始软件安装，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.7.png]]
		+	在软件安装期间，会弹出驱动安装向导，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.8.png]]
		+	直接点击“下一步”，若是首次安装，可能会出现如下对话框：
		+	[[Image:Hollong BLE Sniffer 1.9.png]]
		+	勾选“始终信任”，然后点击“安装”，然后会弹出驱动安装进度对话框，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.10.png]]
		+	驱动安装完毕之后会弹出如下对话框，然后点击“完成”即可：
		+	[[Image:Hollong BLE Sniffer 1.11.png]]
		+	驱动安装完毕之后会弹出Wireshark安装向导，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.12.png]]
		+	直接点击“Next”，出现许可协议，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.13.png]]
		+	点击“I Agree”，出现如下对话框：
		+	[[Image:Hollong BLE Sniffer 1.14.png]]
		+	保持默认勾选项不变，点击“Next”，出现如下对话框：
		+	[[Image:Hollong BLE Sniffer 1.15.png]]
		+	然后再次点击“Next”,出现如下对话框：
		+	[[Image:Hollong BLE Sniffer 1.16.png]]
		+	选择安装目录，此处需要注意，建议使用软件默认安装目录，若是选择了其他安装目录，那么在初次使用BLE Sniffer软件的时候需要手动选择Wireshark.exe文件位置。点击“Next”出现如下对话框：
		+	[[Image:Hollong BLE Sniffer 1.17.png]]
		+	此处需要勾选“Install WinPcap”，然后点击“Next”出现USBPcap安装对话框，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.18.png]]
		+	直接点击“Install”即可，出现安装进度对话框，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.19.png]]
		+	在安装过程会出现WinPcap安装提示对话框，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.20.png]]
		+	点击“Next”，弹出协议对话框，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.21.png]]
		+	点击“I Agree”出现如下对话框：
		+	[[Image:Hollong BLE Sniffer 1.22.png]]
		+	直接点击“Install”开始WinPcap的安装，安装完毕之后出现如下对话框：
		+	[[Image:Hollong BLE Sniffer 1.23.png]]
		+	直接点击“Finish”即可。然后等待Wireshark安装完毕，安装完毕之后出现如下对话框：
		+	[[Image:Hollong BLE Sniffer 1.24.png]]
		+	点击“Next”出现结束安装对话框，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.25.png]]
		+	直接点击“Finish”即可。然后会回到BLE Sniffer软件安装向导，若出现重新启动系统的提示，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.26.png]]
		+	选择“否，稍后重新启动电脑”，然后再点击“完成”即可。
		+
		+	== 使用软件抓包 ==
		+	3.1 将Hollong BLE Sniffer连接到计算机的USB接口上，并让Hollong BLE Sniffer处于Central和Peripherel的信号覆盖范围内，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.27.png]]
		+	首次使用BLE Sniffer会自动安装USB驱动程序，驱动程序安装正常后在设备管理器里面状态如下：
		+	[[Image:Hollong BLE Sniffer 1.28.png]]
		+	3.2 双击桌面“BLE Sniffer”图标，启动BLE Sniffer软件，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.29.png]]
		+	初次使用可能会因为Wireshark软件安装目录不是默认安装目录而导致“Wireshark Directory”为空，那么这里就需要点击“Find Wireshark”找到Wireshark.exe文件所在位置。点击软件上的蓝色三角符号，就会启动BLE Sniffer并开始扫描信号覆盖范围内的蓝牙设备，扫描到设备后会将设备添加到设备列表中，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.30.png]]
		+	点击你要抓取数据的BLE设备，“Select”会变成被选中状态，然后切换到Wireshark软件就能看到抓取到的BLE广播数据了，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.31.png]]
		+	然后我们用手机连接设备，会出现如下数据：
		+	[[Image:Hollong BLE Sniffer 1.32.png]]
		+	这里你将看到整个连接过程，BLE在空中交互的数据，当然这里会有大量的空包，有点影响我们分析查看数据，那么我们可以通过Wireshark的强大过滤器来过滤掉我们不需要的数据，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.33.png]]
		+	点击“表达式”，然后在弹出的对话框中选择“BT ATT”，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.34.png]]
		+	点击“OK”，回到主界面，敲下键盘上的“Enter”键，然后你会发现主界面上就只有我们关心的ATT数据了，如下图所示：
		+	[[Image:Hollong BLE Sniffer 1.35.png]]
