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

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

101 If you use dragino sensors then you can find the recorder on this URL:

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

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

127 == 3.1  Forward data to an external server based on MQTT/HTTP. ==

134 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 == 3.3  Just storing the data on the gateway or external storage. ==
162
163
164 Data can be stored or read by subscribing to topics: (% style="color:#037691" %)**v3/<application_name>/devices/<devices_name>/up**.
165
166 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"]]
167
168 After the configuration is complete, users can find the node logs in the root/ directory

176 = 4.  Sent the downlink to the sensor =
177
178
179 Downlinks can be scheduled by publishing the message to the topic (% style="color:#037691" %)** v3/<application_name>/devices/<devices_name>/down/push**.
180
181 (% 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).**

184
185
186 Instead of /push, you can also use /replace to replace the downlink queue. Replacing with an empty array clears the downlink queue. Example:
187
188 (% class="box" %)
189 (((
190 {
191 "downlinks": [{
192 "f_port": 2,
193 "frm_payload": "AwAA",  
194 "priority": "HIGH",
195 "confirmed": true
196 }]
197 }
