+ * Simple application to indicate connectivity between two nodes:
+ *
+ * - Red led indicates a packet sent via radio (one packet sent each second)
+ * - Yellow led indicates that this node can hear the other node but not
+ *   necessary vice versa (unidirectional communication).
+ * - Green led indicates that both nodes can communicate with each
+ *   other (bidirectional communication)
