The Ultimate Bluetooth Mesh Tutorial (Part 4)
This week we will continue our tutorial series on Bluetooth mesh. Here’s where you can find part 1, part 2, and part 3. But before we get into the practical implementation of an example on the nRF52 series platform, let’s better understand how Bluetooth mesh works on the platform. We’ll go over: The basics and architecture…
Read MoreThe Ultimate Bluetooth Mesh Tutorial (Part 3)
In this post, we’re continuing our tutorial series on Bluetooth mesh (you can find part 1 here and part 2 here). This will be the final post that will cover “theory only” content — in the upcoming posts we’ll start digging into more practice by implementing a Bluetooth mesh example on the Nordic nRF52 series platform.…
Read MoreThe Ultimate Bluetooth Mesh Tutorial (Part 2)
In last week’s tutorial (The Ultimate Bluetooth Mesh Tutorial (Part 1)) in this series on Bluetooth mesh, we covered the following: Basics of Bluetooth mesh Terminology: nodes, elements, states, properties, messages, addresses, publish-subscribe, and managed flooding. In this week’s tutorial, we’ll continue by covering a few more concepts within Bluetooth mesh, including: Models Scenes Types…

Bluetooth has been around for a while. In fact, it recently it celebrated its 20th year anniversary! The introduction of the Bluetooth Low Energy (BLE) standard came in 2010 to address the rapid growth of use cases in the Internet of Things (IoT) field including sensors, wearables, medical devices, etc. However, one thing that BLE…
Read MoreHow to build the simplest nRF52 BLE Central (Lightbulb use case)
In any BLE application, there are (at least) two devices involved: a BLE Peripheral device and a BLE Central device. Usually, the BLE Central is a smartphone, but that doesn’t mean it has to be! What if: you do not want to have to launch an app everytime you want to control a BLE Peripheral?…
Read MoreHow to build the simplest nRF52 BLE Peripheral application (Lightbulb use case)
Let’s face it… One of the hardest things when working with BLE is simply getting started. Whether it’s the setup of the IDE, the configuration of the project, or the implementation the BLE application. I’ve been there… I’ve felt lost, not knowing where and how to start… This is especially true since I was trying…
Read MoreThe complete cross-platform nRF development tutorial
The complete step-by-step cross-platform nRF development tutorial (for Windows, macOS, Linux) In a previous blog post (The complete nRF Mac developmeent tutorial), I went over how to set up your nRF development environment using the NetBeans IDE on a Mac. The beauty with NetBeans is that it’s cross-platform and customizable to fit your needs. I had been…
Read MoreBluetooth 5 speed: How to achieve maximum throughput for your BLE application
Introduction In this second post in the series on Bluetooth 5, we cover the new feature of improved 2x speed along with a general overview of throughput for a BLE application (the previous post went over Bluetooth 5’s new features in general and more specifically covered the increased advertisement capacity feature). First, we need to…
Read MoreBluetooth 5 Advertisements: Everything you need to know
You’ve probably heard so much about the recently released Bluetooth 5. You’ve seen all the hype on 2x Speed, 4x Range, and 8x Advertising data increase capabilities. But what does this all mean?? How does it achieve all these improvements? Is it really possible to achieve all these simultaneously?? What about power consumption? How is that…
Read MoreBluetooth GATT: How to Design Custom Services & Characteristics [MIDI device use case]
I’m sure you’re aware that implementing Bluetooth Low Energy (BLE) for devices that interact with smartphones is one of the best ways to achieve a great user experience for your IoT device. However, designing BLE devices can be a daunting process! You’re probably thinking: “Where do I even start??” One thing I wish I had…
