548 +
549 +==== Overview： ====
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
