607
608 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.
609
610 View the communication signal strength between the node and the gateway through the RSSI value（DRAGINO-LA66-APP currently only supports Android system）

669 === 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 ===
670
671
672 **1.  Register LA66 USB LoRaWAN Module to TTNV3**

678 **2.  Open Node-RED,And import the JSON file to generate the flow**
679
680 Sample JSON file please go to this link to download：放置JSON文件的链接
681
682 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/]]

693 The LA66 USB LoRaWAN Adapter is the same as the LA66 LoRaWAN Shield update method
694
695 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)
