Topology for Mesh Networks using nRF24L01(+)This network layer takes advantage of the fundamental capability of the nRF24L01(+) radio to listen actively to up to 6 other radios at once. The network is arranged in a Tree Topology, where one node is the base, and all other nodes are children either of that node, or of another. Unlike a true mesh network, multiple nodes are not connected together, so there is only one path to any given node.Octal AddressingEach node must be assigned an 15-bit address by the administrator. This address exactly describes the position of the node within the tree. The address is an octal number. Each digit in the address represents a position in the tree further from the base. Node 00 is the base node. Nodes 01-05 are nodes whose parent is the base. Node 021 is the second child of node 01. Node 0321 is the third child of node 021, an so on. The largest node address is 05555, so 3,125 nodes are allowed on a single channel.
Nodes 01-05 are nodes whose parent is the base.
