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
47.4	14
30.2	15	It can be used in some cases such as:
3.1	16
2.1	17	* No internet connection.
	18	* Users want to get data forward in the gateway and forward it to their server based on MQTT/HTTP.
3.1	19	* Forward the data to the built-in Application server Node-Red.
	20	* Just storing the data on the gateway or external storage
2.1	21
47.4	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

	33
	34	The default factory version of LPS8-V2 is installed with the Built-in LoRaWAN Server: (% style="color:blue" %)The Things Network - Stack (Open Source 3.19 Version).
	35
12.1	36	Once the gateway is DHCP an IPV4 address, and then you can access the build-in server TTN-Stack.
