-On this page, we will explain how to turn your Raspberry Pi 3 (also works with 3+) into a broker with the Wifi access point. Having the Raspberry Pi working as an access point means that you will not need an additional router (NB. we have not tested this under heavy load). If you have a spare router and do not wish to install our image then you can follow the instructions [[https://randomnerdtutorials.com/how-to-install-mosquitto-broker-on-raspberry-pi/|here]] on how to turn any Raspberry Pi into a broker.

-Once you have flashed the image to the SD card you should insert it into your Raspberry and boot it up. The Wifi-AP service should activate on its own. But to activate the MQTT broker enter <code>mosquitto -d</code> to the terminal window (you can use SSH or monitor and keyboard to do this). You can use the terminal on Raspbian to confirm if your broker is working. For this, open a terminal window and enter <code>mosquitto_sub -t "mytopic"</code> Then open another terminal window and enter <code>mosquitto_pub -t "mytopic" -m "This is my message"</code>

-If this works then the next thing you should try is connecting your laptop (or other) device to the Raspberry and test publishing and subscribing to messages with it. A good program for debugging is [[en:iot:examples:setup:debugging|MQTTBox]]. You can find the default Wifi name and password below.

 NB!! Avoid turning off Raspberry by removing the power cord since it can cause the SD card to become corrupted. You should always turn the Raspberry off via GUI or typing //sudo shutdown now// to the terminal (using screen and keyboard, or SSH).
-Upgrading Rasbian may stop the initial system from working. Always consider it when upgrading and keep a copy of important configuration files or the original system.

 Power up Raspberry Pi and both modules. Wait until RGB lights up, and then try to press the button on the Button module. RGB module colour should turn green. If this happens, everything is set up correctly. Raspberry Pi serves wifi and MQTT broker service in the given parameters.
