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...

The biggest pain point when debugging an application on the nRF51 series is the inability to set breakpoints while the SoftDevice is active without triggering an assert. Although a workaround exists that allows the debugging process to limp along for...

The new Bluetooth 5 specification promises twice the speed and 4 times the range. Doubling the speed is achieved by increasing the on-air datarate to 2Mbps, while quadrupling the range is achieved by lowering the bitrate to increase the sensitivity o...

PolyMCU is an Open Source Framework which has been designed to be as flexible as possible: host OS independent (support Linux, Windows, MacOS), support any toolchain (GCC, LLVM), any RTOS (ARM RTX, FreeRTOS), any micro-controller vendor SDK (Nordic S...

In December we published a video showing a long range test with the newly released nRF52840 chip. The video showed that the nRF52840 had excellent range, and is fully compatible with the new Long Range feature of the just released Bluetooth 5 specifi...

###Program the boards Connect all the boards to the PC cd to <install_directory>nRF51_ble_broadcast_mesh_0.8.7\nRF51\bootloader Open a command window in that directory Run .\pc-util\for_loop_batch_nRF52 this will program all...

The nRF52832 and nRF52840 devices have a built-in NFC radio which can be used for exposing data as a dynamic NFC tag (a tag with configurable data). This can be used as a standard tag type for storing a web link or a text, to launch apps on smartphon...

Introduce WIZnet would like to introduce a BLE to TCP solution which enables bluetooth devices to access cloud services such as Google, IBM, and Amazon without a smartphone. WIZnet created a low power IoT Gateway using W5500, WizFi310, and nRF52832....
