Relationship between IEEE 802.15.4 and ZigBee in ZNet 2.5

XBee & XBee Gateway XBee - Zigbee

Hello!

I’m trying to figure out how to determine IEEE 802.15.4 parameters of
superframe such as Beacon Interval and Superframe Duration.

Looks like XBee Znet 2.5 do not have commands for set or read this parameters?

ZigBee stack is based on IEEE 802.15.4 as high-level protocol, hence must be methods for specify variables BO (beacon order) and SO (superframe order), which determine duration of superframe and beacon interval, isn’t?

Sorry for my english :slight_smile:

The Znet 2.5 code is a Proprietary mesh protocol developed by Ember that the ZigBee PRO feature set was loosely based off of. As such, it will not have a Beacon order or a Super Frame order.

ZNet 2.5 is a precursor to ZigBee and has not been updated since around 2006. If you have a radio that is running ZNet 2.5, you can update the firmware to run the latest release of ZigBee.

But even on Digi’s 802.15.4 XBee, there is no way to query the information you are looking for without an 802.15.4 sniffer.

ZigBee does use 802.15.4 for it’s underlying infrastructure, but the commands are completely different. There may be some ZDO commands you can send that might reveal what you are looking for.
