This example shows a simple sensor network consisting of node(s),an rpl-border-router and a host connected to
the IPv6 network. The nodes (see also node/README.md) regularly transmit simulated sensor data to the host.
The host visualises the received data.
The Python script tools/Output-Visualisation.py visualises the received data from the nodes.
The script runs on Python27 and uses gnuplot for visualisation.
The following installations are needed (tested with Win32 versions:
- Python 27 (https://www.python.org/download/releases/2.7/)
- gnuplot (http://sourceforge.net/projects/gnuplot/files/gnuplot/)
- gnuplot.py (http://gnuplot-py.sourceforge.net/)
- numpy.py (e.g. http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy)
Manual modification:
Python27\Lib\site-packages\Gnuplot\gp_win32.py
Modify gnuplot_command as in example below
gnuplot_command = r'"C:\Program Files (x86)\gnuplot\bin\gnuplot.exe"'
- The IPv6 addresses of nodes need to be entered in the dictionary "node_data" of tools/Output-Visualisation.py
A user name for the node can be entered in this table as well.
- The script will send a ping message to the next node in the list every 5 seconds. The nodes will obtain
the IPv6 address from this message and start sending "sensor" data to the host.
- Received sensor data is plotted. When no data has been received for more than 30seconds, the plot line
will be dashed.
- Plots are updated once per second.

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

The tx-power-control example can be used to check the link between a node and an rpl-border-router.
After a link is established, the following coap rresources are exposed:
node:
Set-Tx-Power: a PUT/POST resource to set the TX power of the device. The firmware in the device will set the
TX power to the nearest available value.
Get-Tx-Power: a GET resource to retrieve the actual Tx power that is set.
rpl-border-router:
Get-RSSI: a GET resource that shows the detected energy level
Get-Last-RSSI:a GET resource that shows the RSSI of the last received packet. When there is only 1 node, Get-Last-RSSI will
show the effect of changing the TX power level on that node.

This example is a simple TSCH node used to test uart1 functionality of a JN516x on a node.
Note: uart0 is usually configured as serial port for flashing the JN516x and for logging and debug output.
The TX output of uart1 is represented as a PUT/POST resource for a Coap client.
A string entered on a Coap plug-in of a browser will be forwarded over the wireless TSCH network to the
the TX output of UART1.
The RX input of uart1 is represented as an OBSERVABLE resource for a Coap client.
If a string is entered on uart1 that is terminated with a Line Feed or Carriage Return,
a Coap event will notify Coap clients to issue a GET event.
This will make string available at the Coap client side.
The example has been verified on a DR1174 evaluation board
