215 == 3.6 Example: Use TCP in LPS8v2 ==
216
217
218 LPS8v2 includes a local ChirpStack Server and Node-Red. This example shows how to configure LHT65N to use with the local Node-Red server. This example assumes users already have:
219
220 * LHT65N register on LPS8v2 Built-In ChirpStack server already
221 * The user is able to see the data on the built-in ChirpStack server device page.
222
223 Below are steps for LPS8v2 to transfer data from a node to the TCP server.
224
225
226 === 3.6.1 Link Node-Red to Local ChirpStack ===
227
228
229 Users can download the Node-Red decoder from this link and import it into the Node-Red platform: 
230
231 For more information on importing Input Flow, check out this link: **[[Import Input Flow for Dragino Sensors>>url:http://wiki.dragino.com/xwiki/bin/view/Main/Node-RED/#H3.A0ImportInputFlowforDraginoSensors]]**
232
233 After importing the Input Flow is complete, the user needs to edit the MQTT in the node
234
235
236 **~1. Change the Topic**
237
238 Topic modifies it to the following format:
239
240 **application/Application ID/device/End device ID/event/up**
241
242 Reference link: [[**Node-RED integration** >>url:https://www.chirpstack.io/docs/guides/node-red-integration.html]]
243
244 [[image:image-20240122094847-1.png||height="756" width="1232"]]
245
246
247 **2. Enter the MQTT configuration information**
248
249 [[image:image-20240122094930-2.png||height="767" width="1251"]]
250
251
252 **3.** **Click "Update" and Deploy**
253
254 "Connected" indicates that the Link Node-red to Local Chirpstack is normal.
