9 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.
10
11 It can be used in some cases such as:
12
13 * No internet connection.
14 * Users want to get data forward in the gateway and forward it to their server based on MQTT/HTTP.
15 * Forward the data to the built-in Application server Node-Red.
16 * Just storing the data on the gateway or external storage
17
18 The basic of this feature is the decoding of **LoRaWAN ABP End Node**. Requirements:
19
20 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
21 1. LoRaWAN Gateway model: LPS8-V2
22 1. System version: Since V.12
23
24 = 2. Quick Start =
25
26 The default factory version of LPS8-V2 is installed with the Built-in LoRaWAN Server: **The Things Network - Stack (Open Source 3.19 Version).**
27
28 Once the gateway is DHCP an IPV4 address, and then you can access the build-in server TTN-Stack.
29
30
31 = 2.1. Configure the gateway mode =
32
33 You can access  the gateway's Manage Web UI, via the URL ( __**//http:~/~/<hostname> or http:~/~/<local-IPV4-address> //**__) in your browser

49 You can access the gateway's built-in server of **The Things Network - Stack **via the URL( __**//http:~/~/<hostname>:8080 or http:~/~/<local-IPV4-address:8080> //**__) in your browser.

88 == 2.5. Visual Data ==
89
90 In this section, you can be seen that the payload of the sensor has been interpreted as visual data.
91
92 And the next part will discuss where to let the data flow。

97 = 3. Forward the data or store the data =
98
99 You are done most of the work, now you just need to plan the flow of data to where.
100
101 == 3.1. Forward data to an external server based on MQTT/HTTP. ==
102
103
104 === MQTT. ===
105
106 You need to connect to this public address on your external server and subscribe to the topic **(v3/<application_name>/devices/<devices_name>/up)**.

136 = 4. Sent the downlink to the sensor =
137
138
139 Downlinks can be scheduled by publishing the message to the topic v3/{application id}/devices/{device id}/down/push.
140
141 **Note**: **Remember that the format of this topic for The Things Stack Open Source deployment would be (v3/<application_name>/devices/<devices_name>/push).**

144
145
146 Instead of /push, you can also use /replace to replace the downlink queue. Replacing with an empty array clears the downlink queue. Example:
147
148 (% class="box" %)
149 (((
150 {
151 "downlinks": [{
152 "f_port": 2,
153 "frm_payload": "AwAA",  
154 "priority": "HIGH",
155 "confirmed": true
156 }]
157 }
