| 10 | |||
| 11 | |||
| 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 | |||

| 30 | = 2. Quick Start = | ||
| 31 | |||
| 32 | |||
| 33 | 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).** | ||
| 34 | |||
| 35 | Once the gateway is DHCP an IPV4 address, and then you can access the build-in server TTN-Stack. | ||
| 36 | |||
| 37 | |||
| 38 | |||
| 39 | == 2.1. Configure the gateway mode == | ||
| 40 | |||
| 41 | |||
| 42 | 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 | ||

| 60 | == 2.2. Login to the built-in server TTN-Stack == | ||
| 61 | |||
| 62 | |||
| 63 | 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. | ||
| 64 | |||
| 65 | Such as __**//http:~/~/dragino-54ff12:8080 or [[http:~~/~~/<Local-IPV4-Address~>>>http://<Local-IPV4-Address>]]//**__ | ||

| 82 | Here only show the image of the finish, more details about how to add the gateway & sensor refer to this wiki: | ||

| 110 | == 2.5. Visual Data == | ||
| 111 | |||
| 112 | |||
| 113 | In this section, you can be seen that the payload of the sensor has been interpreted as visual data. | ||
| 114 | |||
| 115 | And the next part will discuss where to let the data flow。 | ||

| 123 | |||

| 125 | You are done most of the work, now you just need to plan the flow of data to where. | ||

| 165 | |||
| 166 | Data can be stored or read by subscribing to topics: (% style="color:#037691" %)**v3/<application_name>/devices/<devices_name>/up**. | ||
| 167 | |||
| 168 | 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"]] | ||
| 169 | |||
| 170 | After the configuration is complete, users can find the node logs in the root/ directory | ||

| 188 | = 4. Sent the downlink to the sensor = | ||
| 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 | (% 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).** | ||

| 197 | |||
| 198 | Instead of /push, you can also use /replace to replace the downlink queue. Replacing with an empty array clears the downlink queue. Example: | ||
