Want to learn the basics of Bluetooth Low Energy in under 4 hours?

I've crafted this easy-to-read guide to be the best possible introduction and most up-to-date for learning Bluetooth Low Energy (LE) technology. My promise to you: you will go from being confused, and knowing nothing about Bluetooth Low Energy to becoming confident and knowing everything you need to know to get started with developing your first Bluetooth Low Energy application or product!

Who Am I? And Why Should You Even Care?

I’m Mohammad Afaneh, a Bluetooth Developer and Founder of Novel Bits and the Bluetooth Developer Academy.

I’ve been on your journey before...

I’ve gone from a newbie to an expert in BLE development. Having worked with Bluetooth Low Energy (BLE) since 2014, I've experienced all the stages that you go through from being a beginner all the way up to becoming an expert in the field.

You might ask "What makes you qualified as a Bluetooth Expert"?

  • I’ve self-published two top-rated books on the topic: Intro to Bluetooth Low Energy and Bluetooth 5 & BLE: A Developer's Guide. Both of which have helped hundreds of developers get started with learning BLE and developing BLE products efficiently.
  • I've created an educational YouTube video series all about Bluetooth Low Energy technology that's been watched and referenced by thousands of developers.
  • I've consulted for the Bluetooth Special Interest Group (SIG) for two and half years as the Developer Relations Manager for the Americas region.
  • I've consulted for tens of startups and Fortune 500 companies on the design, architecture, and marketing of Bluetooth Low Energy products.

I’ve felt the pain of the often enormous learning curve associated with developing Bluetooth Low Energy products!

I've learned the hard way, wasting days and weeks getting up to speed while struggling with poor or non-existent resources.

...and that's why I started this website, blog, and this whole business (which I run full-time).

I hope you find the provided information and resources helpful for your throughout your BLE learning journey!

 

All the best,
Mohammad

An overview of Bluetooth Beacons – Part 1

By Mohammad Afaneh | February 10, 2020

Last Updated on May 19, 2020 by Mohammad Afaneh For many of us, our first encounters with Bluetooth probably came in the form of wireless headsets and hands-free devices. However, a new breed of Bluetooth devices is emerging — they are lower in cost and they consume less power. From a non-technical and user perspective, the name Bluetooth appears to cover any form of Bluetooth connectivity and requires some sort of manual activation via your…

Implementing Over-the-Air Device Firmware Update (OTA DFU) – Part 1

By Mohammad Afaneh | January 20, 2020

Last Updated on May 6, 2022 by Mohammad Afaneh Introduction One of the most important and critical features of wirelessly-connected devices is the capability of over-the-air device firmware updates (aka OTA DFU). You may be asking “why is this becoming an increasingly popular and in-demand feature?” Well, it’s due to many good reasons, some of which are: The increasing demand by end-users for new functionality. To address bugs and security vulnerabilities (critical and non-critical). To…

Zephyr Tutorial: Bluetooth Low Energy Development

By Mohammad Afaneh | January 13, 2020

Last Updated on May 6, 2022 by Mohammad Afaneh What is the Zephyr Project? Zephyr is an open-source real-time operating system (RTOS) meant for use on resource-constrained embedded systems. This can range from simple sensor devices without connectivity to much more complex IoT devices such as smartwatches and medical devices. Zephyr is a Linux Foundation project that is backed by many members including Intel, NXP Semiconductors, Synopsys, Linaro, Texas Instruments, DeviceTone, Nordic Semiconductor, Oticon and Bose. The project’s source code is licensed under the…

How to Achieve Ranges of over 1 Km using Bluetooth Low Energy (LE Coded PHY)

By Mohammad Afaneh | January 6, 2020

Last Updated on April 11, 2022 by Mohammad Afaneh Introduction Bluetooth Low Energy was designed to provide considerably reduced power consumption and cost while maintaining communication ranges similar to Bluetooth Classic.  However, that is no longer the case. With Bluetooth Version 5.0, a new “long-range” mode was introduced. You can now achieve ranges of over 1 kilometer using Bluetooth Low Energy! Long-range mode is not only useful for extending the range of a Bluetooth connection…
