Maximum number of XBee devices in API mode

XBee & XBee Gateway XBee - 802.15.4
1

Hi guys,

Is there a limit to the maximum number of devices that can operate simultaneously in API mode?

I want to use an XBee Pro as a transmitter, sending unicast data to up to 30 XBees. Most of the time data will be intended for just one Xbee but there will be occasions when I’d like to send a broadcast message to all devices.

For the unicast messages I’d like to receive an acknowledgement but I don’t need acks for the broadcast messages.

Is this possible? I don’t really fancy buying 30 XBees and connecting them up to PCs to try it!

I think the limit is somewhere around 65000…

4.1.2. Joining an XBee ZNet 2.5 Router or End Device to a PAN
…
Each router and coordinator can allow up to 8 end device children to join. Once 8 end device
children have joined a particular router or coordinator, that device cannot allow any more end
devices to join to it until its network parameters are reset (see section 4.1.6).
…
So, the maximum number of devices would be: 1 coordinator with 8 routers, each router with 8 end devices = 1+8*8 = 65.
Or even less devices???

Which module are you using?

Series 1 or Series 2?

And there is the limit of End device per coordinator or router in case of zigbee. But there is not limitations that how many routers can be joined.
