Hello,
Currently the available devices with ZigBee support are the JN516x family.
The currently supported stacks by KW24D are: Thread, 802.15.4 MAC and SMAC.
ZigBee 3.0 will be supported in KW41Z in Q1 2018 and currently there are no plans to support this stack in KW24D.
Sorry for the inconvenience that this might cause you.
Best Regards,
Estephania
