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
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?
