604 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.
605
606 View the communication signal strength between the node and the gateway through the RSSI value（DRAGINO-LA66-APP currently only supports Android system）
