The Lumpy Ci40 Application

The Lumpy Ci40 is part of bigger project called "Weather Station". Using code from this repository you will be able to handle various sensor clicks inserted into your Ci40 board. Values measured by those clicks will be sent to Creator Device Server.

Environment for Weather Station project

The complete IoT Environment is builded with following components:

• LWM2M cloud server
• Ci40 application which allows usage of clicks in mirkroBUS sockets.
• Contiki based applications build for clicker platform:
  • Temperature sensor
• a mobile application to present Weather measurements.

Ci40 Application Specific Dependencies

This application uses the Awa LightweightM2M implementation of the OMA Lightweight M2M protocol to provide a secure and standards compliant device management solution without the need for an intimate knowledge of M2M protocols. Additionnaly MikroE Clicks support is done through LetMeCreate library.

Integration With OpenWrt

It's assumed that you have build envriroment for ci40 openWrt described here and this is located in folder work. So structure inside will be:

work/
  build/  
  constrained-os/  
  dist/
  packages/

Clone this repository into work/packages, after this operation structure will look:

work/
  build/  
  constrained-os/  
  dist/
  packages/
    weather-station-gateway

Now copy folder from packages/weather-station-gateway/feeds into work/dist/openwrt-ckt-feeds. Then execute commands:

cd work/dist/openwrt
./scripts/feeds update
./scripts/feeds update weather-station-gateway
./scripts/feeds install weather-station-gateway
make menuconfig

in menuconfig please press / and type weather-station-gateway one occurrence will appear. Mark it with <*> and do save of config. In terminal type make to build openwrt image with this application. After uploading to ci40 edit file located in /etc/init.d/weather_station_initd and put proper switch arguments related to clicks which you put into mikroBus port.

Setup For Execution - Development

Lumpy uses an AWA LwM2M Client to communicate the with the Creator Device server It requires few steps to be done before running the project.
First of all you need to go to Creator Developer Console and create certificate which will be used to make secure connection. If you havent done this earlier, you will find usefull informations on Creator Device Server page. The execute the daemon run this command:

 $ awa_clientd --bootstrap coaps://deviceserver.flowcloud.systems:15684 --endPointName WeatherStationDevice --certificate=/root/certificate.crt --ipcPort 12345 -p7000 -d

Then you have to provide IPSO object definitions, to do so please run clientObjectsDefine.sh script from scripts folder (make sure the AWA LwM2M Client Daemon is working!).

 $ ./clientObjectsDefine.sh

And here you go! Wait! No! Put some clicks into Ci40 MikroBUS, and then you can execute Lumpy with one of following options:

Switch	Description
-1, --click1	Type of click installed in microBUS slot 1 (default:none)
-2, --click2	Type of click installed in microBUS slot 2 (default:none)
-s, --sleep	Delay between measurements in seconds. (default: 60s)
-v, --logLevel	Debug level from 1 to 5 (default:info): fatal(1), error(2), warning(3), info(4), debug(5) and max(>5)
-h, --help	prints help

Please refer to section 'Supported Clicks' to obtain argument values for switch --click1 and --click2. If one of slots is empty you can skip proper switch or set it's value to none.

For example, connect a Thermo 3 Click (temperature sensor), to MikroBus 1. Then execute the following command:

$ ./weatherStation -1 thermo3

Finally, you can check the updated temperature values on the Creator Developer Console.

Supported Clicks

From wide range of MikroE clicks in this project you can use:

Click	weatherStation argument name
Air Quality	air
Carbon Monoxide	co
Thermo3	thermo3
Thunder	thunder
Weather	weather
