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

24 **The basic of this feature is the decoding of** (% style="color:blue" %)**LoRaWAN ABP End Node**(%%). **Requirements:**
25
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

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.

114
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。

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

168 Data can be stored or read by subscribing to topics: (% style="color:#037691" %)**v3/<application_name>/devices/<devices_name>/up**.

170 Then add the storage node (% style="color:#037691" %)**(write file)**(%%), Users can download the Node-Red flowchart from this link to test data storage：[[attach:test_data_storage.json||target="_blank"]]

172 After the configuration is complete, users can find the node logs in the root/ directory

189
190
191 Downlinks can be scheduled by publishing the message to the topic (% style="color:#037691" %)** v3/<application_name>/devices/<devices_name>/down/push**.
192
193
194 (% 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).**

198
199
200 Instead of /push, you can also use /replace to replace the downlink queue. Replacing with an empty array clears the downlink queue.

205 (((

207 "downlinks": [{
208 "f_port": 2,
209 "frm_payload": "AwAA",
