3.1	12	The LPS8-V2 of Dragino LoRaWAN gateway can communicate with LoRaWAN ABP End Node, the working is based on the built-in server TTN-Stack.
2.1	13
30.2	14	It can be used in some cases such as:
3.1	15
2.1	16	* No internet connection.
	17	* Users want to get data forward in the gateway and forward it to their server based on MQTT/HTTP.
3.1	18	* Forward the data to the built-in Application server Node-Red.
	19	* Just storing the data on the gateway or external storage
2.1	20
30.4	21
	22
30.2	23	The basic of this feature is the decoding of (% style="color:blue" %)LoRaWAN ABP End Node(%%). Requirements:
	24
2.1	25	1. LoRaWAN End Node in ABP mode. Make sure your end node works in this mode. End node most are default set to OTAA mode
	26	1. LoRaWAN Gateway model: LPS8-V2
	27	1. System version: Since V.12

	37

	181	Instead of /push, you can also use /replace to replace the downlink queue. Replacing with an empty array clears the downlink queue. Example:
