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

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

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

111 == 2.5.  Visual Data ==
112
113
114 In this section, you can be seen that the payload of the sensor has been interpreted as visual data.
115
116 And the next part will discuss where to let the data flow。

126 You are done most of the work, now you just need to plan the flow of data to where.

130 == 3.1  Forward data to an external server based on MQTT/HTTP. ==

137 You need to connect to this public address on your external server and subscribe to the topic **(v3/<application_name>/devices/<devices_name>/up)**.

164 == 3.3  Just storing the data on the gateway or external storage. ==
165
166
167 Data can be stored or read by subscribing to topics: (% style="color:#037691" %)**v3/<application_name>/devices/<devices_name>/#**.
168
169 Then add the storage node **(write file)**, Users can download the Node-Red flowchart from this link to test data storage：[[attach:test_data_storage.json||target="_blank"]]
170
171 After the configuration is complete, users can find the node logs in the root/ directory

179 = 4.  Sent the downlink to the sensor =
180
181
182 Downlinks can be scheduled by publishing the message to the topic (% style="color:#037691" %)** v3/<application_name>/devices/<devices_name>/down/push**.
183
184 (% 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).**

187
188
189 Instead of /push, you can also use /replace to replace the downlink queue. Replacing with an empty array clears the downlink queue. Example:
190
191 (% class="box" %)
192 (((
193 {
194 "downlinks": [{
195 "f_port": 2,
196 "frm_payload": "AwAA",  
197 "priority": "HIGH",
198 "confirmed": true
199 }]
