553 +
554 +==== Overview： ====
555 +
556 +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.
557 +
558 +View the communication signal strength between the node and the gateway through the RSSI value（DRAGINO-LA66-APP currently only supports Android system）
559 +
560 +==== Conditions of Use： ====
561 +
562 +Requires a type-c to USB adapter
