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.
13
14 **It can be used in some cases such as:**
15
16 * No internet connection.
17 * Users want to get data forward in the gateway and forward it to their server based on MQTT/HTTP.
18 * Forward the data to the built-in Application server Node-Red.
19 * Just storing the data on the gateway or external storage

23 **The basic of this feature is the decoding of** (% style="color:blue" %)**LoRaWAN ABP End Node**(%%). **Requirements:**
24
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

36 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).**
37
38 Once the gateway is DHCP an IPV4 address, and then you can access the build-in server TTN-Stack.

115
116 In this section, you can be seen that the payload of the sensor has been interpreted as visual data.

118 And the next part will discuss where to let the data flow。

172
173
174 Downlinks can be scheduled by publishing the message to the topic (% style="color:#037691" %)** v3/<application_name>/devices/<devices_name>/down/push**.
175
176 (% style="color:red" %)**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).**

179
180
181 Instead of /push, you can also use /replace to replace the downlink queue. Replacing with an empty array clears the downlink queue. Example:
182
183 (% class="box" %)
184 (((
185 {
186 "downlinks": [{
187 "f_port": 2,
188 "frm_payload": "AwAA",  
189 "priority": "HIGH",
190 "confirmed": true
191 }]
