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.

Installing and upgrading the necessary libraries to interact with the board


Now, we will run many commands in the SSH client. Make sure that your SSH client is connected to the Yocto Linux SSH server running on the board as explained in the preceding section before running the commands. Specially, if you are working with either OS X or Linux, you have to make sure that you don't run the commands on your computer instead of doing this on the remote shell. Its simple, just make sure you always see the prompt root@galileo:~# before running any command.

Tip

Your board should be connected to a LAN with Internet access because we will download content from the Internet.

We will use the opkg utility to download and install the updated version of both the mraa and upm libraries. The mraa library, also known as libmraa, is a low level C/C++ library with bindings to Python that allows us to interface with the I/O features on the Intel Galileo Gen 2 board and other supported platforms. The upm library...
