Interpreting the simulation application scene above:
The distance from Module A to Module C is 70 meters, beyond 50 meters of our module's transmission distance, so
module A cannot send data directly to module C. If a module B is placed between module A and module C, the data will
be relayed by B and then received by module C.
Module A needs to send data to the whole thing.The network, modules B, C, D, E need to receive data from A, then
module A will send the data at the broadcast address(0XFFFF).
If module A needs to specify data issuance, All you need to do is write the address of module E at the address in the data
format (see instruction format for details). But module E is 140 meters away from module A and cannot communicate the
data directly, but as long as these modules are on the same network, the data will be there.The following link reaches
module E, where A sends data to B, B to C, C to D, D to E

Basic Concept
4.1.1 NetKey
Network keys are used to protect network-layer communications.is a key generated by using a random number generator
that meets the core specifications.(See Mesh Profile 3.86)
