Internet of Things with Python

By: Gaston C. Hillar

Overview of this book

Internet of Things (IoT) is revolutionizing the way devices/things interact with each other. And when you have IoT with Python on your side, you'll be able to build interactive objects and design them. This book lets you stay at the forefront of cutting-edge research on IoT. We'll open up the possibilities using tools that enable you to interact with the world, such as Intel Galileo Gen 2, sensors, and other hardware. You will learn how to read, write, and convert digital values to generate analog output by programming Pulse Width Modulation (PWM) in Python. You will get familiar with the complex communication system included in the board, so you can interact with any shield, actuator, or sensor. Later on, you will not only see how to work with data received from the sensors, but also perform actions by sending them to a specific shield. You'll be able to connect your IoT device to the entire world, by integrating WiFi, Bluetooth, and Internet settings. With everything ready, you will see how to work in real time on your IoT device using the MQTT protocol in python. By the end of the book, you will be able to develop IoT prototypes with Python, libraries, and tools.

Retrieving the board's assigned IP address


The board has finished the boot process with the Yocto Linux microSD card and is connected to our LAN throught the Ethernet port. The DHCP server has assigned the board an IP address and we need to know it in order to run commands on a Yocto Linux console. There are many ways for us to retrieve the board's assigned IP address. We will explore the different options and you can choose the most convenient one based on your LAN configuration.

If the board is connected to one of the Ethernet ports of a Wireless router and we have access to the router's Web interface, we can easily know the IP address assigned to the board. Some router's Web interfaces display the wired clients list. As our board is connected through an Ethernet wire, it will be listed as one of the wired clients and the device MAC address will match the MAC address printer in the adhesive label on the board's Ethernet jacket. The following picture shows the Wired-clients list in a router...
