Is 16-bit address of Zigbee coordinator always 0?

Other Parts Discussed in Thread: Z-STACK

I read in this document that the 16-bit address of the Zigbee coordinator is always 0... is that true? I know the document is for an xbee part but I was not sure if this is true for anything that is Zigbee compliant.

Hi DMMT,

As long as you are using the Z-Stack the 0x0000 NWK

address is a special address that belongs to the

Coordinator of a ZigBee network.

Just to clarify, the choice of network address 0x0000 for the network coordinator is not specific to the Z-Stack implementation of the ZigBee specification (is there any other that matters, anyway?) But rather, 0x0000 is mandated by the ZigBee specification itself. For some light, summer reading, take a look at section 3.6.1.1 Establishing a Network. In paragraph 7 you'll read this:

Once a PAN identifier is selected, the NLME shall select a 16-bit network address
equal to 0x0000 and set the nwkNetworkAddress attribute of the NIB equal to the
selected network address.

Being the fashionistas that we are here (or whiners, as the case may be) , we might prefer the default ZC address of 0xBEBE ;)

The excerpt above is from the 608-page tome known as the ZigBee Specification, R19.

If you finish that before your vacation is over, there is always "War and Peace" by Leo Tolstoy ;)
