219 +== 3.6 Example: Use TCP in LPS8v2 ==
220 +
221 +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:
222 +
223 +* LHT65N register on LPS8v2 Built-In ChirpStack server already
224 +* The user is able to see the data on the built-in ChirpStack server device page.
225 +
226 +Below are steps for LPS8v2 to transfer data from a node to the TCP server.
227 +
228 +=== 3.6.1 Link Node-Red to Local ChirpStack ===
229 +
230 +Users can download the Node-Red decoder from this link and import it into the Node-Red platform: 
231 +
232 +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]]**
233 +
234 +After importing the Input Flow is complete, the user needs to edit the MQTT in the node
