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...

Nordic has recently contributed support for the 2Mbit/s PHY, part of the Bluetooth 5.0 specification, to the Zephyr Project RTOS. The video below shows how to configure, build and test GATT data throughput on a nRF52840 SoC running Zephyr RTOS. T...

I realize that there are already multiple tutorials on how to configure GCC along with Eclipse or SEGGER Embedded Studio (for use on a Mac), but this tutorial goes over setting up a different IDE. The more choices the better, right? ;) The IDE of ch...

Bluetooth 5 - now arriving in smartphones As we know, Bluetooth 5 was launched last December by the Bluetooth SIG. The nRF52 Series from Nordic have always had Bluetooth 5 and its arrival in the mix for the nRF52 Series and this family of SoCs was d...

Most guides out there are unclear and made for machines. Here is a full guide how to setup Segger for mac OS X with some example project from the SDK ( or even a PC but not tested), and also how to debug like a human not using terminal. ( or using it...

Short note how to make FreeRTOS program debugging with eclipse little simpler. If you are looking the information how to configure the whole environment see this post: https://devzone.nordicsemi.com/tutorials/7/development-with-gcc-and-eclipse/ Wha...

The first in a series of blogs that will help educate on what is most important about Bluetooth 5 and take you deeper into the details of how it works and how you can benefit most from using it. Taking Bluetooth further, faster Bluetooth 5 has be...

Several users have pointed out a sudden flash size increase in some of our Bluetooth examples. We decided to write a quick post here to describe the reason for this and explain how to decrease the size of the examples. The reason for the size increa...
