EDIT: It seems less weird now. See You will never guess how JLink deals with UART flow control for the full story. Working on some Python code to control nRF51 and nrF52 targets I encountered a strange issue with pyserial. I don't have the full e...

#Introduction All compilers ARE NOT created equal. Given the same c code, different compilers will generate machine code with varying performance & size. Generally the more efficient machine code (uses less CPU cycles/machine instructions to per...

External Power Amplifiers and LNAs easily connected to the nRF52 series device for high power extended range operation. Data sheets, white papers, schematics and layout information available at link text

This tutorial shows how to use the mbed framework to develop applications for Nordic nRF51 devices. Before you begin, install VisualGDB 5.1 or later. Start Visual Studio and open the VisualGDB Embedded Project Wizard:![01-prjname](http://visualgd...

The S132 SoftDevice for the nRF52 has support for enable/disable switching of external Power Amplifiers (PA) and Low Noise Amplifiers (LNA) using GPIO pins. This was introduced in S132 version 2.0.0-7.alpha. In the nRF51 there was an option to use t...

The purpose of this blog is to provide a step by step guide to help a developer, starting off with the Nordic Semiconductor nRF51 DK, to get the necessary tools installed and get the software (SW) development environment setup so that the user can st...

Hi all, I implemented a simple multilink NUS central based on s130 for nrf51 chip-set. It means that this NUS central can connect to several peripherals simultaneously and send data to each one of them by selecting connection index. It is designed a...

This tutorial will take less than 15 minutes. #Motivation Never lose a BLE connection when debugging your applications again! This technique will also be useful for any application using the PWM peripheral and many others as well! Monitor mode deb...

As you start developing with the nRF5 series chips, SoftDevices, and SDKs, it's very useful to learn how errors can be discovered (and preferrably recovered from). This can be detecting something as simple as using invalid parameters to a function, o...

Hi all, I developed an iBeacon application example with nrf51 chip-set. The firmware has been developed on top of softdevice s110 and Nordic SDK running on a nrf51 PCA10028 Dev. Kit. I used an arm-eabi-none GCC toolchain and JLink under Ubuntu. Fin...

Most outstanding EMEA Semiconductor Company An award from the Global Semiconductor Alliance (GSA) is widely considered as one of the tier 1 awards that a semiconductor company can receive. Nordic Semiconductor has been recognized as the most outst...

One SDK for nRF5x SoC The latest SDK is now available in alpha version for nRF51 and nRF52 SoC. A big change with this SDK is that we have merged the SDK for both nRF5x SoCs into one SDK. This will hopefully make development simpler and more straigh...

GPS for Bluetooth Smart In 2014 I've developed a Bluetooth Smart apps couple to transmit and receive a GPS location and speed with this nice technology. The apps are called LE GPS (transmitter, peripheral role) and LE GPS Rec (receiver, central rol...

The next evolution of nRFready Smart Remote is here Nordic has for a number of years catered to the remote control engineering community with our high performance feature-laden smart remote reference designs. The 3rd generation nRFready Smart Remo...

We are now one step closer to the production release (v1.0) of our new Bluetooth Smart desktop application. The development team has been hard at work adding new features and improving the existing functionality of the application. Figure 1: Servi...

We have recently released a new version of the nRF5 Software Development Kit (SDK) for IoT, an IPv6-ready Internet Protocol Suite for Nordic's nRF52 Series Bluetooth Smart SoCs. In addition to enabling native and interoperable Internet Protocol (IP) ...

Senior lecturing staff at PKU with representatives from Smart Device Innovationn Lab sponsors ARM, ST and Nordic Nordic has over the past 18 months or so been working in partnership with ARM on a partnership program for universities called ‘Lab-in...

Check the infocenter explanation There are lots of improvements in nRF52 compared to nRF51. Features that are the same in both products are not mentioned here, only changes worth mentioning will be described. It is expected that you have prior knowl...

It is exciting to see that the Bluetooth SIG officially announced a preview of its technology roadmap for 2016[1]. This will enable new applications and innovative products with Bluetooth Smart in the future that take advantage of the benefits of lo...

An automatic radio test was developed based on Enhanced Shockburst (ESB), which works for all the nRF Series Chips including, nRF24LE1, nRF24LU1P, nRF51x22, as well as nRF52832. Source code is available as attached. ##What's it for?## The Purposes...

Over the last few weeks the Nordic team has been working on getting support for programming our devices in Linux as well as adding support for using our Python programming module ‘Pynrfjprog’ with Python 3. We are pleased to report that this support...

OSX command line application for performing an nRF51 device firmware update: https://github.com/jeremysf/nrfDFU This is a simple command line program I wrote based on Nordic's documentation and their RF Toolbox https://github.com/NordicSemiconducto...

This tutorial shows how to build and debug Bluetooth LE beacon firmware for the nRF51 Beacon Kit. We will use Segger J-Link together with a Tag Connect cable to debug the beacon. We will show how to use an Android phone with the Nordic nRF Toolbox Ap...

In this project, we will build a two-wheeled robot based on the Nordic nRF51822 BLE SoC. Motor control for the two wheels of the robot will be done using an L293D chip. The robot can be controlled using any mobile device that has BLE, and when not ...

The Cannybot Brain is a robotics controller board that uses the Nordic Semiconductor nRF51822 at its core. The board has been developed by Cannybots Limited in Cambridge, UK. One of Cannybots core values is connecting kids to the modern technology t...
