Two coordinator on same channel and with same PAN id

Prasoon Sharma

Hello all,

What will happen if two Coordinators(running their own separate networks), with same PanID running on same channel, which were initially situated far away from each other, at some point of time comes in range of each other?

Either one of those two coordinators would change PANID when there’s PANID conflict detected.

And how will the network nodesreact to the change in PANID

The node would lose connection and try to rejoin original network. Do you intend to use the same PANID? Since it’s not a good practice, I would suggest you don’t do that.

So you mean as soon as one of the coordinator changes the PANID, all the network nodes associated with it leaves the network? which, in my opinion, should not happen according to the zigbee specifications? Please correct me if I'm wrong.

I do not intend to use same PANID, I just want to know what will happen in that scenario.

Actually, it would happen when device trying to communicate using original PANID and find there’s something wrong with original PANID network. So, it won’t be immediately.
