Changing Xbee Modem Type


I have 2 Xbee-PRO S2 modules. After read them with the X-CTU software, they both have XBP24-ZB Modem type.
After bought them, I realised that because of my Network needs (one coordinator and 100+ End Devices => most time sleeping) they won’t be able to make this work with this kind of protocol (ZigBee Coordinator only allows 12 End devices).
I think that Xbee PRO 802.15.4 protocol can do this, so i tried to change my default Xbee modem type from XBP24-ZB to XBP24, but I couldn’t.

Error : “Getting modem type…OK
Programming modem…Flash checksum error failed
Write Parameters…Failed”

So, I have two questions:

1) Which is the Protocol that suits my needs?
I need only one Device (Server - Coordinator) that only receive (no need to send back) every End-Device (100+) message whenever they send one. And all End-Devices needs to sleep 99% of the time (thats why I don’t use routers)

2) Why I can’t change my Modem Type from XBP24-ZB to XBP24? Can I only use the XBP24-ZB Protocol?

Thank you!! :slight_smile:

XBP24-ZB is your modem type (XBP24/XB24 is the 802.15.4 modem type)
You cannot change that for your hardware. You would have to buy an XBP24 or XB24 to use it.

You can change the “Function Set” for you XBP24-ZB but they all look to be zigbee related.

Digi Mesh suits well for your requirement.
