706 +
707 +Sample JSON file please go to **[[this link>>https://www.dropbox.com/sh/zxwx16qb777uvkz/AABE_P8coGCQ4DAC8enH4bUya?dl=0]]** to download.

709 +For the usage of Node-RED, please refer to: [[http:~~/~~/wiki.dragino.com/xwiki/bin/view/Main/Node-RED/>>http://wiki.dragino.com/xwiki/bin/view/Main/Node-RED/]]
710 +
711 +After see LoRaWAN Online, walk around and the APP will keep sending location info to LoRaWAN server and then to the Node Red.
712 +
713 +
714 +Example output in NodeRed is as below:
