533 +
534 +==== Overview： ====
535 +
536 +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.
537 +
538 +View the communication signal strength between the node and the gateway through the RSSI value（DRAGINO-LA66-APP currently only supports Android system）
539 +
540 +==== Conditions of Use： ====
541 +
542 +Requires a type-c to USB adapter
