216 == 3.6 Example: Use TCP in LPS8v2 ==
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 === 3.6.1 Link Node-Red to Local ChirpStack ===
226
227 Users can download the Node-Red decoder from this link and import it into the Node-Red platform: 
228
229 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]]**
230
231 After importing the Input Flow is complete, the user needs to edit the MQTT in the node
232
233
234 **~1. Change the Topic**
235
236 Topic modifies it to the following format:
237
238 **application/Application ID/device/End device ID/event/up**

251 **3.** **Click "Update" and Deploy**
252
253 "Connected" indicates that the Link Node-red to Local Chirpstack is normal.
