/** RF24Mesh_Example_Master.ino by TMRh20
 *
 * Note: This sketch only functions on -Arduino Due-
 *
 * This example sketch shows how to manually configure a node via RF24Mesh as a master node, which
 * will receive all data from sensor nodes.
 *
 * The nodes can change physical or logical position in the network, and reconnect through different
 * routing nodes as required. The master node manages the address assignments for the individual nodes
 * in a manner similar to DHCP.
