How to fully understand packet sniffer?

Hi,

Am also facing same problem.

Did you get the explanation for this?

thanks in advance

Hi,

For understanding these fields, you should search a little bit deeper:

Here, take a look on this document (ZigBee-PRO fields formatting)

Hi again,

Though the above mentioned document is very useful for understanding fields formatting

in ZigBee APS and NWK layers, it might give you no answer for your question.

Here's a link to a book on google.books that might be more relevant to you (select page 70).

Hi,

it looks like when source address is 2-bytes long, it's Node ID ; and when it's 8-bytes long, it's the MAC address.

Simple explanations could be seen at :

 - http://www.sics.se/~adam/contiki/docs-uipv6/a01103.html, chapter 3 "MAC Overview" for the basis

 - http://www.libelium.com/security_802.15.4_zigbee/ with security

To finish, why not the 802.15.4 specs : http://standards.ieee.org/getieee802/download/802.15.4-2006.pdf, chapter 7.2 "MAC Frame Format".

I think you should find everything youv need.

Hope this helps,
