Figure 4-7. Node Joins Network Via Rejoin Procedure with PDS Not Used in Application.
The Persist Data Server (PDS) Component provides useful API to store networking parameters to persistent memory to
retain them over device resets. See section PDS in [1].
With PDS APIs used in application, the node сan be configured
to come back into the network without performing over-the-air rejoin procedure.
In Figure 4-8, the node
with short address 0x0001 joins network via rejoin from packet #3.
Just before packet #13, this node is reset and it is seen that the device does not do further rejoin to come into the
network.
The node reset behavior and further restoration of configuration server parameters with PDS can be verified by looking
at the values of the sequence numbers and counter values in various layers. These parameters are among the config.
server parameters and hence are restored on rejoin with PDS implemented. Without PDS implementation, the stack
resets these values to default values on startup.
