Hi,

I am a newbie to Zigbee. Someone told me that Zigbee devices of different manufacturers are not compatible. Does that mean, that all devices in one Zigbee network must use the same chip from a manufacturer?

I have searched the answer in internet for a long time but could not get the correct description.

Thanks
Owen

They supposed to be compatible, but certification process ensures that they are compatible only against reference device (Golden Unit), but not with each other. So occasionally you may face minor incompatibilities.

In regular ZigBee implementations most of incompatibilities are already eliminated, but there are a lot of them in newer features, like new profiles or security schemes.

Hi,

Thank you.

How can I know if my Zigbee devices with Atmega128RFA1 are compatible with others in advance?

So far as I understand there is no standardized application layer for Zigbee. Is it correct? OK, the added profiles such as Home Automation belong to application layer.

Thanks
Owen

You don't until you try.

There is no application layer. ZigBee "guarantees" compliance on a network layer. When profiles are added on top of the stack they should be compatible, but profiles are relatively new and some of them utilize very complex security schemes (Smart Energy for example), so it does not always work as expected between multiple vendors.

Just checking to confirm you know: ZigBee is not a synonym of IEEE 802.15.4. Just like IP is not a synonym of IEEE 802.3 or 802.11. Network layer.

802.15.4 assures interoperability of chips (MAC and PHY) if both use the same IEEE defined options. ZigBee and 6LoWPAN and ISA100.11 and others try to assure interoperability at the network layer atop 802.15.4.
