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.

It actually sticks to the sink and stays where it is supposed to. Well made. We love it!
Color: Silver
Finely, a sink caddy that actually sticks to the sink! We have been so frustrated trying to find one that does. This one is great. We just used the suction cups, which are large and there are 3 of them. If finely actually stays there!

Works & Looks Great!
This item comes with two options for sticking to the sink, suction cups & an adhesive thing. I decided to try the suction cups first, that way I can remove them to clean, plus I wanted to test out the position of where I put it on the sink. They work great! I haven’t had to re-stick not once. Great staying power! And it looks really good! Also, the seller sent a follow-up message just to check in & offer answers if any questions arose. That meant the world to me, like it’s not every day a seller cares what you think once money changes hands. 10/10 would recommend!

need a smooth sink surface for this to work
Color: Silver
Suction cups didn't stick to my sink and kept falling; to be fair, surface of my sink is textured.

Three months later, it's a keeper
Color: Silver
I hate it when reviews are left one day after the product arrives. At that point, there's no way of knowing if the item is going to last. When my last sink caddy went bad (the suction cups rotted out and the wires had started to rust), I ordered this as a replacement. Inexpensive, functional, worth a try. There were two things that impressed me when this arrived. The suction cups weren't permanently mounted, so if they fell apart, the caddy was still worthwhile. Secondly, the company offered free replacement suction cups if the time came I needed them. That struck me as above-and-beyond; I had no idea this was part of the package. I'm happy with this. It looks good, I detach the sink caddy regularly when I want to move it out of the way, and it pops right back into place. For the money, I don't think you can beat it.
