RF24Mesh  V1.0.3b
A user friendly mesh overlay for sensor networks using RF24Network and nRF24L01 radio modules
RF24Mesh_Example_Master.ino

Arduino Example Sketch

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.
