Which of the following ZigBee devices do not have the ability to route commands and can only send and receive commands?

The ZigBee End device is designed specifically for limited functions in a ZigBee network. These devices can send and receive commands, but they do not have the capability to route commands to other devices. Their primary role is to communicate with either the Coordinator or Routers to transmit data or receive instructions. This simplicity in function allows them to conserve power, enabling longer battery life, which is crucial for devices that may be deployed in remote or difficult-to-access locations.

In contrast, the ZigBee Coordinator is responsible for managing the entire network, including device discovery and synchronization. The Router can relay messages between devices, expanding the network coverage and ensuring that data can travel longer distances by hopping through multiple devices. A Gateway typically acts as a bridge between the ZigBee network and other networks, allowing for interoperability and communication across different protocols.

Therefore, the unique features of the ZigBee End device make it clear that it lacks routing capabilities, fulfilling its role as a straightforward communication point within the network.
