3. Aims
   • Illustrate how to build a very basic IoT product, serial could be
   printed on a screen.
   • No hard coded SSID / Password
   • No hard coded MQTT URL and credentials.
   • Simple
   • Encapsulate some of the hard stuff

4. Testing the ESPlant
   • Connect to the ESPlant using USB
   • Open the Arduino Serial Monitor
   • Copy the Access Token and note the name of your AP!
   • Connect to your AP
   • Connect the device to wifi using the following command
   • curl -v -H "Authorization: Token access_token_here“ 'http://

5. Testing Continued.
   • Install mosquitto (MQTT client and server)
   • Find out your IP and configure the ESPlant to send messages to your system using
   the following command.
   • The IP address of your ESPlant is printed to the console once it reboots and
   connects to wifi.
   • Also you need your IP address of course.
   • curl -v -H "Authorization: Token access_token_here" ‘http://X.X.X.X:9000/
   mqttSetup?mqtt_url=mqtt://test@x.x.x.x'
   • mosquitto_sub -v -t '#'
