zigbee link status
In the zigbee network, no matter what kind of device it is, as long as it is powered on, it will send link status packets at an interval of 15 seconds per packet. This packet contains the connection status of this device with other devices in the same network.
As can be seen from the example in the above figure, this device can detect that 4 devices are connected to itself, one device is the coordinator, and the others are routing node devices. At the same time, the status value of each connection to this device can be seen from the figure. It must be remembered that both Incoming Cost and Outgoing Cost are numbers from 0 to 7 to indicate connection status. 0- means down, 1- is the best link, and 7 is really the worst.
