The Nordic Global Tech Tour is about to hit the road again. This time it is all about the goodies inside our nRF52 Series for Bluetooth Smart and what they enable you to do.
The Nordic Global Tech Tour (GTT) is always an exci...
Since I couldn't find the information of how the supply current would change with different supply voltage for nrf51 chip, this is the result of a little test that I made to get this info.
Setup: nrf51 DK with variable voltage source connected to P2...
I have been using Eclipse to programming+build+flash+debugging my nRF51 DK apps.
This requires carrying a Makefile forward, modifying as stuff changes...handling flash programming in less integrated way....

When I decided to attempt the reprogramming of my nRF51822 Beacon Kit I read several posts related to the task. The information I needed was there but I found it to be a bit scattered. It was difficult for me to put it all together; particularly so a...
The Infocenter – our new documentation portal - has now been up and running since June and contains all of our technical documentation. We saw the need for this because we wanted to make our complete library more visible, and since the documentation...
We recently announced that we now support “extended industrial temperature range” (-40 – 105C) on our nRF51822.
The devices supporting -40 - 105C are the QFAA (QFN with 256kB flash and 16kB RAM) and the CEAA (WCSP with 256kB flash and 16kB RAM) vers...
Introduction
Using proprietary protocols can be an effective way of addressing shortcomings in BLE. When communicating between two nRF chips, one can for example use a different packet format or different symbol rate to improve throughput or increas...
Hello everybody,
I have just published the sourcecode of FruityMesh on GitHub. It is a meshing algorithm that uses standard BLE connections. Plug in as many nodes as you like and they will automatically build a mesh without any user interaction. Y...
This tutorial shows how to create and debug a basic project for the Nordic nRF51-DK using Visual Studio. Before you begin, install VisualGDB 5.0 or later.

In this project, we will control two motors over BLE using the Nordic nRF51-DK. To do this, we will use a motor driver based on the Toshiba TB6612FNG chip. We will use GPIOs and PWM to communicate with this board.
