 ===== -. 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]].

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]]. The tool can be directly downloaded from this {{ :mqtt-spy-1.0.0.jar.zip |link}}.
-You can use mqtt-spy to debug the messages received from the LoRaWAN devices. The tool is provided at the beginning of the challenge. 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''.
