The network will support monitoring of micro-climate conditions in vineyards. Here below you can find a detailed description of the experimental platform implementing an end-to-end LoRaWAN solution. The platform consists of the following elements:
-The platform consists of the following elements:+
  
-  * Wireless devices implementing the LoRaWAN protocol +  * Devices that communicate to one or more gateways via a wireless interface using single hop LoRa and implementing the LoRaWAN protocol. These devices are physically connected to sensors that generate data.  
-  * Gateway or base station +  * Gateways or base stations that forward frames between the devices and the network server. Gateways are connected to the network server via IP interfaces. 
-  * LoRAWAN backend +  * LoRAWAN backend that implements the network server functions and provides frame control and security. 
-  * Application +  * Applications that enable to visualize and store the sensor data obtained from the devices.

 Starting with the devices in the LoRaWAN platform, we will use an [[http://support.sodaq.com/sodaq-one/autonomо/|Autonomo]] board with a LoRaBee Microchip RN2483 module. According to [[http://shop.sodaq.com]], Autonomo is a matchbox-sized powerhouse which uses the new Atmel Cortex M0+ 32bit micro controller. One advantage of such device is that it can be powered by a smartphone-sized solar panel. Starting with the devices in the LoRaWAN platform, we will use an [[http://support.sodaq.com/sodaq-one/autonomо/|Autonomo]] board with a LoRaBee Microchip RN2483 module.

 +You can also find another example of sketch to download: {{ :test-loraserver-moisture-on-move.ino.zip |}}. Here the message sending is not periodic but related to an event. For example, an infrared sensor detects a movement and triggers a signal for the device to send a LoRaWAN message. Note also that the join method used in this second sketch is Activation by Personalisation (ABP): the device address, the network session key, and the application session key are directly configured on the device.

 +[{{ :app-loraserver.png?direct&400 | Figure 5. Loraserver web interface}}]
 +
 +Start by creating and application as in Figure 5. Then create a node in this application and provide the following information:
 +  * A unique node name
 +  * The node description
 +  * A unique device EUI on 64 bits: Random identifiers can be generated on [[https://www.random.org/bytes/]]
 +  * The application EUI on 64 bits: this can be a common identifier for all nodes using the same application.
 +  * A unique application key on 128 bits
 +
 +In order to enable OTAA join method, you have to make sure that the ''ABP activation'' button is unchecked.

-===== -. Applications ===== +mqtt-spy is an open source utility intended to help you with monitoring activity on MQTT topics. It has been designed to deal with high volumes of messages, as well as occasional publications. mqtt-spy is a JavaFX application, so it should work on any operating system with an appropriate version of Java 8 installed. A very useful tutorial is available on [[https://github.com/eclipse/paho.mqtt-spy/wiki]]
-==== -. MQTT spy ==== +You can use mqtt-spy to debug the messages received from the LoRaWAN devicesFor this, you should download the software tool from [[https://github.com/eclipse/paho.mqtt-spy/wiki]]. After starting the application, configure a new connection to the MQTT broker by simply adding the IP address of the broker in the ''Server URI'' field. Now you can subscribe to any MQTT topic. If you want to receive all messages arriving at the backend, you can use the generic topic ''#''. You can also limit to the topic including the messages of any specific device: ''application/APPLICATION_ID/node/DEVICE_EUI/rx''
