Story

This project shows the monitoring the status of an Analog Input (sensor) through CoAP protocol. The first step to making this project is the installation of Contiki OS and 6lbr web server on Raspberry; you can follow this process on: https://github.com/Telecontrolli/6lbr-on-Telecontrolli-Devices-XIP/tree/version-1.3. Then you must connect the X.IP5 with the Photoresistor VT935 through Jumper Cable. See the schematic below.

Firmware

Generate the two firmware (X.IP5 slip-radio/X.IP5-web-demo) to be loaded on the X.IP5 devices. To execute this process, we need the SmartRF06EB with cables and Flash Programmer 2 software. Completing this process, we can execute this project:

Connect the X.IP5 slip-radio device with the Raspberry.

Connect to X.IP5 web-demo device output Button with the PIN that we find in the case board.h

Connect the X.IP5 web-demo device with micro USB to power supply.

Open command prompt on Raspberry and type: "sudo service 6lbr start" and press Enter.

System running

If the procedure is correct, the system works.

Open Mozilla Firefox browser on your PC.

In the search bar, type the gateway address "http://[bbbb::100]”.

6lbr main screen will be open, go on the “sensors” item menu to read the sensor generated.

Now you can operate with the sensor through the 6lbr.

In the table, click on the word “coap”. In the screen just opened you can control the sensors through the network.

Please note, if the CoAP doesn’t work, you must install Copper CU - the additional plugin for Mozilla - and restart the browser. You can download Copper CU from this link: https://addons.mozilla.org/it/firefox/addon/copper-270430/
