XBee 2.5 Network without coordinator.

XBee & XBee Gateway XBee - 802.15.4
1

Hello.

Some time ago, I used several XBee modules from version 1 to build a peer to peer network. All of them were set as en devices. Some messages were broadcast, and some other specific to one station.

To do that I just set channel and PAN ID.

Now, I’d like to implement something similar but whith XBee modules from version 2.5, but as far I can understand, there MUST be a coordinator. As my network is changing in time and space, a coordinator may not be always available.

Is it possible to make a network without coordinators? It would be enough to make all end devices sending broadcast packets.

Regards.

I don’t know the answer to your question (sorry!) but maybe a couple of points might be helpful:

Given that this is a ZNet2.5 question, you might stand more chance of a good answer if you posted it in the ZNet forum.

And have you considered using Zigbee instead of ZNet? The Zigbee firmware runs on the same hardware and is a more recent development.

hi,

No. ZigBee networks need coordinator on each networks.
Probably, it will be better for the series 1 to use it, if it is such ways for use.

Oops, and with version 2.5 is not possible to make a real P2P network?

If one node is set as coordinator and other nodes are set as router, it will function as Peer to Peer network in fact.
