For Raspberry Pi, ESP32 and nRF52 with Python, Arduino and Zephyr Bluetooth Low Energy (BLE) radio chips are ubiquitous from Raspberry Pi to light bulbs. BLE is an elaborate technology with a comprehensive specification, but the basics are quite accessible. A progressive and systematic approach will lead you far in mastering this wireless communication technique, which is essential for working in low power scenarios. In this book, you’ll learn how to: Discover BLE devices in the neighborhood by listening to their advertisements. Create your own BLE devices advertising data. Connect to BLE devices such as heart rate monitors and proximity reporters. Create secure connections to BLE devices with encryption and authentication. Understand BLE service and profile specifications and implement them. Reverse engineer a BLE device with a proprietary implementation and control it with your own software. Make your BLE devices use as little power as possible. This book shows you the ropes of BLE programming with Python and the Bleak library on a Raspberry Pi or PC, with C++ and NimBLE-Arduino on Espressif’s ESP32 development boards, and with C on one of the development boards supported by the Zephyr real-time operating system, such as Nordic Semiconductor's nRF52 boards. Starting with a very little amount of theory, you’ll develop code right from the beginning. After you’ve completed this book, you’ll know enough to create your own BLE applications.

In this book the author presents all essential aspects of microcontroller programming, without overloading the reader with unnecessary or quasi-relevant bits of information. Having read the book, you should be able to understand as well as program, 8-bit microcontrollers. The introduction to microcontroller programming is worked out using microcontrollers from the PIC series. Not exactly state-of-the-art with just 8 bits, the PIC micro has the advantage of being easy to comprehend. It is offered in a DIP enclosure, widely available and not overly complex. The entire datasheet of the PIC micro is shorter by decades than the description of the architecture outlining the processor section of an advanced microcontroller. Simplicity has its advantages here. Having mastered the fundamental operation of a microcontroller, you can easily enter into the realms of advanced softcores later. Having placed assembly code as the executive programming language in the foreground in the first part of the book, the author reaches a deeper level with ‘C’ in the second part. Cheerfully alongside the official subject matter, the book presents tips & tricks, interesting measurement technology, practical aspects of microcontroller programming, as well as hands-on options for easier working, debugging and faultfinding.

The short-wave technique has a very particular appeal: It can easily bridge long distances. By reflecting short-wave signals off the conductive layers of the ionosphere, they can be received in places beyond the horizon and therefore can reach anywhere on earth. Although technology is striving for ever higher frequencies, and radio is usually listened to on FM, DAB+, satellite or the Internet, modern means of transmission require extensive infrastructure and are extremely vulnerable. In the event of a global power outage, there is nothing more important than the short-wave. Amateur radio is not only a hobby, it’s also an emergency radio system! Elektor’s SDR-Shield is a versatile shortwave receiver up to 30 MHz. Using an Arduino and the appropriate software, radio stations, morse signals, SSB stations, and digital signals can be received. In this book, successful author and enthusiastic radio amateur, Burkhard Kainka describes the modern practice of software defined radio using the Elektor SDR Shield. He not only imparts a theoretical background but also explains numerous open source software tools.
