[:duplicate thread]

I wonder which version of 802.15.4 standard (2003 or 2011 or 2015) is using by SmartThings Hub V3 for ZigBee functionality. I guess the version depends on the ZigBee MCU on PCB of SmartThings Hub, but I didn’t disamble the hub and check the ZigBee MCU.

Yes, it likely depends on which chip they purchased for the Zigbee radio.
