RF24Mesh_Example.cpp

Raspberry Pi Example Sketch
This example sketch shows how to manually configure a node via RF24Mesh, and send data to the master node. The nodes will refresh their network address as soon as a single write fails. This allows the nodes to change position in relation to each other and the master node.
