参考Nordic官方例程修改，python3环境执行

https://www.nordicsemi.com/eng/Products/Bluetooth-low-energy/nRF-Sniffer http://www.nordicsemi.com/eng/Products/Bluetooth-low-energy/nRF-Sniffer#Downloads

环境

>=python3.5.2
>=pyserial3.4
>=wireshark2.4.5

测试环境

win10
nrf52832 DK板（P10040）
（linux or osx 应该也没有问题）

配置

解压至".\Wireshark\extcap"

端口测试

命令行执行：nrf_sniffer.bat --extcap-interfaces

extcap {version=2.0.0}{display=nRF Sniffer}{help=http://www.nordicsemi.com/eng/Products/Bluetooth-low-energy/nRF-Sniffer#Downloads}

运行

1，开发板烧录对应hex文件，如nrf52_DK板: ".\hex\sniffer_pca10040_51296aa"
2，上电，等待3-5秒，串口稳定，打开wireshark，发现成功注册“nRF Sniffer COMx”信息，如果未出现，重做此步骤
3，打开“nRF Sniffer COMx”，开始抓包，如果打开后没有信息输出，重做步骤2
4，关机结束

谢谢
