 ## A flow process in Node-RED
+A basic process is implemented on *Node-RED* to test the mqtt protocol. Thus, add the next blocks:

+1. `mqtt in` from network group
+2. `debug` from common
+3. `text`from dashboard
+
+then, double-click on `mqtt-in` to open and edit the node:
+![]()
+
+click on *Add new mqtt-brocker*, then, in the *Connection* tab: set *Name* to Rasp, point the server to the raspberry's ip or hostname and port 1883. Leave unchanged the *Security* and *Message* tabs and click on the **Add** button. 
+
+

+
+
+how  to connect???
