-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.

+==== -. mqtt-spy ====
+mqtt-spy is an open source utility intended to help you with monitoring activity on MQTT topics. It's been designed to deal with high volumes of messages, as well as occasional publications. mqtt-spy is a JavaFX application, so 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]].
+Start by downloading the software tool from the previous link. After launching, 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 a MQTT topic: you can receive all messages by entering the '#' topic or limit to the topic including the messages of a specific device: ''application/1/node/DEVICE_EUI/rx''.
