请问下R21是什么。
Implemented Orphan Scan Notification as the child aging keep-alive
mechanism required by the R21 specification.
可能是指：ZigBee Pro Specification (R21)
You have to be at least Zigbee Participant member to access this spec.
Does ZigBee spec R21 mean ZigBee spec 3.0?
3.0协议栈应该是基于ZigBee Spec R21的。
