How does ZigBee implement the routing relay function?
In principle, the routing function dynamically maintains a routing table. Due to the limited application of Zigbee and limited resources, it is impossible to maintain a large table. Therefore, when needed, the node sends routing information requests and establishes routes. For specific implementations, you need to refer to protocol specifications, or use the protocol stack provided by the chip vendor.
For example, with FastZigBee protocol, to ensure AB two terminal configuration can make two normal communication, in the distance is too far away to do communication, as long as the AB into the middle of the routing node, you can return to normal communication points, other configuration does not need to be modified.
If you need to know is with their development, the need to be familiar with ZigBee protocol stack, this time, now a lot of ZigBee transmission module with the route relay function, for example of this kind of ZM5168 module, routing functions are very easy to use.
