Our Industrial IoT demo series continues. Today, we will demonstrate how to perform FOTA updates on the 4ZeroBox over WiFi. More precisely, we will show you how to connect the 4ZeroBox to the Zerynth Device Manager, send data to a Cloud service, and then how to use the FOTA (Firmware-Over-The-Air) update procedure to update the firmware on the 4ZeroBox.
FOTA updates offer many advantages – you can update your device from anywhere, you can continuously add new features, and update devices on a large scale with minimum disruption to the application and the end-user.
Of course, this kind of demo is a great starting point if you are looking for a way to learn more about industrial IoT and Python programming.
If you are interested, you can take a look at the rest of the tutorials from this series:
To start the demo, you will first need to connect the 4ZeroBox with your PC, with a USB cable:
Regarding the power supply, you can use a USB or external 24V power supply. Compared to the previous versions of the 4ZeroBox, there are no jumpers, so just connect the desired power supply and continue with the board setup.
