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
20
21 **The basic of this feature is the decoding of** (% style="color:blue" %)**LoRaWAN ABP End Node**(%%). **Requirements:**
22
23 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
24 1. LoRaWAN Gateway model: LPS8-V2
25 1. System version: Since V.12
26
27 = 2.  Quick Start =

29
30 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).**
31
32 Once the gateway is DHCP an IPV4 address, and then you can access the build-in server TTN-Stack.

39 You can access  the gateway's Manage Web UI, via the URL ( (% style="color:blue" %)__**//http:~/~/<hostname> or http:~/~/<local-IPV4-address> //**__(%%)) in your browser

107 == 2.5.  Visual Data ==
108
109
110 In this section, you can be seen that the payload of the sensor has been interpreted as visual data.
111
112 And the next part will discuss where to let the data flow。

119 = 3.  Forward the data or store the data =
120
121
122 You are done most of the work, now you just need to plan the flow of data to where.

126 == 3.1  Forward data to an external server based on MQTT/HTTP. ==

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

161
162
163 Data can be stored or read by subscribing to topics: (% style="color:#037691" %)**v3/<application_name>/devices/<devices_name>/up**.
164
165 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"]]
166
167 After the configuration is complete, users can find the node logs in the root/ directory

181 = 4.  Sent the downlink to the sensor =
182
183
184 Downlinks can be scheduled by publishing the message to the topic (% style="color:#037691" %)** v3/<application_name>/devices/<devices_name>/down/push**.
185
186 (% 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).**

189
190
191 Instead of /push, you can also use /replace to replace the downlink queue. Replacing with an empty array clears the downlink queue. Example:
192
193 (% class="box" %)
194 (((
195 {
196 "downlinks": [{
197 "f_port": 2,
198 "frm_payload": "AwAA",  
199 "priority": "HIGH",
200 "confirmed": true
201 }]
