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

30.2	22
	23
	24	The basic of this feature is the decoding of (% style="color:blue" %)LoRaWAN ABP End Node(%%). Requirements:
	25
2.1	26	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
	27	1. LoRaWAN Gateway model: LPS8-V2
	28	1. System version: Since V.12

	37	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).
	38
12.1	39	Once the gateway is DHCP an IPV4 address, and then you can access the build-in server TTN-Stack.

	157

30.1	159	Downlinks can be scheduled by publishing the message to the topic v3/<application_name>/devices/<devices_name>/down/push.
23.1	160
30.1	161	Note: Remember that the format of this topic for The Things Stack Open Source deployment would be (v3/<application_name>/devices/<devices_name>/down/push).

	164
	165
	166	Instead of /push, you can also use /replace to replace the downlink queue. Replacing with an empty array clears the downlink queue. Example:
	167
27.1	168	(% class="box" %)
	169	(((
	170	{
	171	"downlinks": [{
