106.1	534	==== Overview： ====
	535
111.1	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.
106.1	537
111.1	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
106.1	540	==== Conditions of Use： ====
	541
	542	Requires a type-c to USB adapter
