Bluetooth SIG has recently published a new standard, the Bluetooth mesh. The mesh capability is a significant update and enables radical new applications. This in turn means that there are significant changes, and many new concepts to learn for devel...

Introduction With nRF5 SDK v14.0.0, we have significantly refactored the Command Line Interface (CLI) module to make it more useful and user friendly. The new CLI has the following features: Support for multiple instances. Advanced cooperation ...

Introduction I would like to introduce simple source code that supporting NUS profile and pairing. Most of you will choose the proprietary profile to make your own application which is not provided by Bluetooth SIG. Since this reason Nordic is provi...

As you probably know having a build environment, you can replicate and deploy with ease has the potential to save a lot of R&D time. If you can also control its versioning so you would be able to "get back in time" for a build server th...

When we built our Bluey nRF52 BLE dev board, we were looking for an inexpensive option for our users to upload code to bluey and debug it using ARM GDB. We then came across the blackmagic probe (BMP) project - an Open Source debugging tool for embe...

The day after the Bluetooth SIG announced the 1.0 spec of the Bluetooth mesh we are happy to announce the nRF5 SDK for Mesh for our nRF51 and nRF52 Series SoCs. This first (v0.9.1) release is packed with new features and concepts for Bluetooth. What...

We’ve all seen the hype on 2x Speed, 4x Range, and 8x Advertising data increase capabilities in Bluetooth 5. But what does this all mean?? How does it achieve all these improvements? Is it really possible to achieve all these simultaneously?? What a...

Motivation Very often, while working with Bluetooth LE devices, we encountered a problem having to repeat a sequence of operations to test or demonstrate some functionality. Writing a mobile app every time to show couple of buttons that interact wit...

With the nRF52840, we released our first System-on-Chip (SoC) with a radio that is capable of running the IEEE 802.15.4 PHY, additionally to Bluetooth 5 (Bluetooth Low Energy), ANT+, and proprietary 2.4 GHz protocols. In March 2017, we released our f...

A case study on optimizing battery power consumption for CC2538 but can also apply for nRF52 based device - https://medium.com/jumperiot/power-optimization-from-3-to-7-months-on-a-single-charge-56de0c30f062.

In this project, we’re going to build a BLE Beacon that transmits temperature, humidity and ambient light levels to a dashboard on the internet. Bluetooth Low Energy is a technology that was designed from the ground up to reduce power consumption. ...

Our brilliant apps engineers continue to play around with our newly-launched Nordic Thingy:52. This time, Joakim has prepared a few Javascript demos using node.js and a Raspberry Pi. The Thingy connects to the Raspberry Pi with Bluetooth and uses i...

We are happy to announce that nRF Connect for desktop v2.0 has now been released, and is available for download on the nRF Connect product page. Framework for desktop apps As you may know, nRF Connect v1 was a Bluetooth low energy tool for developm...

Connecting BLE devices to the IoT is becoming an essential requirement of many products, so to help you get your IoT project jump started, Nordic Semiconductor is launching a set of IoT developer tools. Currently the tools are in beta with a full rel...

How to implement the Nordic OTA protocol in your own phone App This document is meant to be useful if you are implementing DFU updates within in your own smartphone app, and want to do it yourself, rather than rely on trying to turn nrf toolbox into...

One thing I wish I had when I started developing for BLE is more blog posts that walk you step-by-step on how to tackle the different phases of the system design and implementation. One such phase is designing your Bluetooth GATT: Services and Charac...

Nordic Developer Zone - The Nordic developer’s best friend The original goal of Nordic Developer zone was to create a resource for our customers that would complement direct Nordic technical support. It should simplify and help them with their desig...

Introduction This example shows a simple GPIO driver for seamless handling of the GPIO and GPIOTE peripherals of the nRF52 series. This example is particularly intended for developers who wish to develop their own driver. The code is available on Gi...

TL;DR If you just want to navigate (without debugging) through the nRF5-SDK using CLion, follow the following steps. For debugging go to “Debugging the nRF52 with CLion” in the full post. (optional) Create a backup for your current nrf5-SDK dir...

Introduction: This is a guide for the uninitiated, which I am most qualified to write. These tips cover the items I wish I had understood when I got my evaluation kits. Nordic support covered these items but I thought it might be helpful as one ne...

We are very excited to inform you that we have introduced our new software licenses with the release of SDK v13.0. The new licenses are based on the well-known BSD license class and give more flexibility and freedom to customers while still protectin...

IoT systems are all about analytics from physical infrastructure and are expected to work accurately. After deploying an IoT system one must take care of supporting customers, assure SLA and run root cause analysis on production systems, with real ...

The Earthquake Machine This is a brief overview of our bachelor's project results. The bachelor's project is given by Nordic Semiconductor for students at NTNU. Our goal was to induce resonance in objects by making some sort of device which could be...

Released in December 2016, the new Bluetooth 5 offers truly exciting possibilities for home, industry, and commerce as well as the more traditional areas of wearables and personal devices historically associated with Bluetooth. Nordic’s nRF52832 i...

1.1 Description This documentation describes the use and initialization of the Serial Wire Debug Port (SWDP) interface when writing to or reading from Flash and SRAM of the nRF52832 Rev 1. See http://infocenter.nordicsemi.com/ for more information o...
