550 -
551 -DRAGINO-LA66-APP is a mobile APP for LA66 USB LoRaWAN Module. DRAGINO-LA66-APP can obtain the positioning information of the mobile phone and send it to the LoRaWAN platform through the LA66 USB LoRaWAN Module.
552 -
553 -View the communication signal strength between the node and the gateway through the RSSI value（DRAGINO-LA66-APP currently only supports Android system）
554 -
555 -==== Conditions of Use： ====
556 -
557 -Requires a type-c to USB adapter
