wireshark zigbee

hi，

1.Now I am using Wireshark to capture nrF52840 DK ZigBee packets. I have configured the environment according to the guide. In wireshark, "nRF Sniffer for 802.15.4" can be displayed, but when I click to capture packets,  The interface will be stuck for a long time, and the state is "unresponsive".  After a while into the "is capturing the packet" interface, but a communication packet capture, I tried a lot of methods do not know what is the reason for this problem?  I also hope that you can help me solve the problem. I have tried many versions of Wireshark, but they failed. They are always very slow and zigBee data cannot be captured  

2.What are zigBee channels set up according to?  Channel 11 by default?

Hello,

Did you get this message when you first selected the "nRF Sniffer for 802.15.4"?

This is where you set the channel you want to capture the packets. 

Then you should start seeing packets on that channel. Make sure that you have set the same channel on the nRF that is running the zigbee application. 

If the issue is that the sniffer is not set up properly, please refer to the getting started guide for nRF Sniffer for 802.15.4.

Best regards,

Edvin

hi.

What is the channel set according to? Is it set according to the port number?  

[Edvin]

By default, the channel is set to 16. If you haven't changed this, then you should try to sniff on channel 16. If you want to change the channel that your zigbee devices operate on, you can set this in your project.

I don't know whether you are using the legacy nRF5 SDK for Thread and Zigbee (if so, what version?) or if you are using NCS.

If you are using the legacy SDK, search for ZIGBEE_CHANNEL in sdk_config.h, and set it to whatever channel you want to use (between 11 and 26. If you are using NCS, please add 

CONFIG_ZIGBEE_CHANNEL=12

if you want to use channel 12. Same rules: Pick one between 11 and 26.

My wireshark is a bit weird. It crashes every time I try to save or exit wireshark, so I am not sure whether this applies to everyone, but I am only able to select the 802.15.4 channel I want to sniff the first time I open it. After it crashes it won't let me chose another channel until a few hours have passed, and wireshark has been closed. 

BR,

Edvin
