602 DRAGINO-LA66-APP is a mobile APP for LA66 USB LoRaWAN Adapter and APP sample process. DRAGINO-LA66-APP can obtain the positioning information of the mobile phone and send it to the LoRaWAN platform through the LA66 USB LoRaWAN Adapter.
603
604 View the communication signal strength between the node and the gateway through the RSSI value（DRAGINO-LA66-APP currently only supports Android system）

663 === 3.8.2 Use DRAGINO-LA66-APP to obtain positioning information and send it to TTNV3 through LA66 USB LoRaWAN Adapter and integrate it into Node-RED ===
664
665
666 **1.  Register LA66 USB LoRaWAN Module to TTNV3**

672 **2.  Open Node-RED,And import the JSON file to generate the flow**
673
674 Sample JSON file please go to this link to download：放置JSON文件的链接
675
676 For the usage of Node-RED, please refer to: [[http:~~/~~/8.211.40.43:8080/xwiki/bin/view/Main/Node-RED/>>http://8.211.40.43:8080/xwiki/bin/view/Main/Node-RED/]]

687 The LA66 USB LoRaWAN Adapter is the same as the LA66 LoRaWAN Shield update method
688
689 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)
