Implementing Nordic nRF52 OTA DFU over Bluetooth LE – Part 4
In a few previous posts (Part 1, Part 2, and Part 3), we covered the basics of designing a secure Over-the-Air Device Firmware Update (OTA DFU) process, an overview of the Nordic nRF52 OTA DFU process, as well as testing out one of the DFU examples included in the nRF5 SDK. In this tutorial, we…
Read MoreHow to Manage Multiple BLE Peripherals in iOS [SwiftUI]
This tutorial is an excerpt from a course available within the Bluetooth Developer Academy, developed in collaboration with Anas Imtiaz, Ph.D. For the purpose of this tutorial (separated into two parts), our goal is to create an iOS app that can manage multiple BLE peripherals. Our example will be an app that can be used…
Read MoreImplementing Bluetooth Beacons (iBeacon) – nRF52 use case
Introduction As a continuation of our series on Bluetooth beacons (part 1 here and part 2 here), today we cover Apple’s iBeacon standard in a bit more detail. iBeacon is especially useful for deploying location-awareness applications and monitoring user behavior within an area. It was introduced in iOS 7 and utilizes Bluetooth Low Energy (BLE)…
Read MoreImplementing Over-the-Air Device Firmware Update for nRF52 – Part 3
Introduction In the previous post, Implementing Over-the-Air Device Firmware Update for nRF52 – Part 2, we introduced the OTA DFU process on the nRF52. In this post, we’ll go over testing the process using one of the DFU examples included in the nRF5 SDK, the “BLE Secure DFU Bootloader” example.. The hardware requirements for running the BLE…
Read MoreImplementing Over-the-Air Device Firmware Update for nRF52 – Part 2
Introduction In the previous post, Implementing Over-the-Air Device Firmware Update (OTA DFU) – Part 1, we gave an introduction to over-the-air device firmware update (OTA DFU) and went over the best practices for implementing secure and efficient firmware updates. In this second post in the series, we’ll go over the OTA DFU process used and…
Read MoreImplementing Over-the-Air Device Firmware Update (OTA DFU) – Part 1
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…
Read MorenRF52 Development using Visual Studio Code [macOS]
Introduction When it comes to IDEs and advanced text editors we, developers, have so many choices… probably too many! But that’s not necessarily a bad thing. Having these many choices can be overwhelming, and if you’re a tools geek like me, you end up spending hours and hours just exploring and trying out new tools…
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
In a previous blog post (The complete nRF Mac development 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 using NetBeans for over a decade, so I was very comfortable…
Read MoreBluetooth GATT: How to Design Custom Services & Characteristics [MIDI device use case]
You’re probably aware that adding Bluetooth Low Energy (BLE) to your device is one of the best ways to achieve a great user experience for your IoT device. Why is that, you may ask? Well, adding BLE allows your device to be connectable from a smartphone app. And we can all agree that smartphone apps…
Read MoreThe complete nRF52 Mac development tutorial
[Update] I’ve published a more up-to-date version of this blog post that covers all three major operating systems (macOS, Windows, and Linux) using a different IDE. Check it out here: The complete cross-platform nRF development tutorial Today’s tutorial focuses on setting up the environment for nRF52 Mac development and debugging for Bluetooth Low Energy applications.…
