+Node is part of Simple-Sensor-Network
+When node is connected to border-router (TSCH), it will wait to be addressed by a host
+on port 8185. 
+When addressed, IPv6 address of host is acquired. Node will start to transmit samples of
+a waveform ("simulated" sensor data) to the host on port 8186 at a rate of once per 
+10 seconds. Type of waveform and phase depend on mac address of node in order to better 
+distinguish the waveforms at the host side.
+LED is flashed every time a sample is transmitted.
+Nodes are tested with configuration JN516x_WITH_DONGLE=1
