688 +(% style="color:blue" %)**2.  Open Node-RED,And import the JSON file to generate the flow**
689 +
690 +Sample JSON file please go to **[[this link>>https://www.dropbox.com/sh/zxwx16qb777uvkz/AABE_P8coGCQ4DAC8enH4bUya?dl=0]]** to download.
691 +
692 +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/]]
693 +
694 +After see LoRaWAN Online, walk around and the APP will keep sending location info to LoRaWAN server and then to the Node Red.
695 +
696 +
697 +Example output in NodeRed is as below:

704 +
705 +
706 +The LA66 USB LoRaWAN Adapter is the same as the LA66 LoRaWAN Shield update method
707 +
708 +Just use the yellow jumper cap to short the BOOT corner and the RX corner, and then press the RESET button (without the jumper cap, you can directly short the BOOT corner and the RX corner with a wire to achieve the same effect)
