Summary
Construction of a cordova based cross platform mobile app that displays heart rate measurement data sent by a Nordic nRF51822 device via BLE. This data is periodically posting this to thingspeak as well.
Our goal is to create a mobile ap...
Here is an example of a hardware setup to measure the voltage on a Lithium battery with a voltage divider on nRF52. The Lithium battery typically has a voltage range of 2.7 - 4.2 V and we (Nordic) recommend that you divide the battery voltage with tw...
This series of posts will describe a new toy here at Nordic: The nRF Hexapod. The post will be divided in multiple parts, this part describing the project in general and the hardware that is required. All parts of this project is open source so you...
Sometimes we look for what will be the best demo for BLE operation between mobile device and peer device. Recently Blinky is one of perfect application, but I suggest one more interesting example between mobile game based on Android and nRF51-DK or n...

nRF Connect is the new official name of the Bluetooth Smart tool previously known as Yggdrasil. We have now reached Release ...
Since NFC is one of new feature on nRF52, some customers often ask how to verify NFC tag they are implementing. The purpose of this blog is to provide how to setup and how the implementation based on SDK is shown on the reader. This is somewhat simpl...
Bluetooth LE is ideal for Internet of Things applications where many low powered sensors or devices feed data through a gateway and out onto the internet. An optimal solution would move away from the use of smartphones, which are not always available...
Recently, Google introduced some news about Eddystone. At the same time, we released a first implementation of the new specification on GitHub to get developers started. I would like to share some insights on what this is all about.
For those of y...
We in the Nordic Support team have created an online power profiler to estimate the power consumption during a BLE event with different parameters. The profiler gives you information about the different components in a BLE event as well as the averag...
#Why use trace
"Embedded Trace Macrocell (ETM) allows to capture information on the processor’s state without affecting the processor’s performance. Microcontrollers that include an ETM allow detailed program execution to be recorded and saved ...
Now delivering into kids hands in UK
BBC micro:bit has, as I write this, been delivered into the hands of 450 000 UK schoolchildren with a further 500 000+ to be handed out over the next couple of weeks. On 22nd March I was present at the official...
The award winning nRF51822 is now available as an ultra-thin Chip Scale Package) CSP variant. Measuring just 3.38mm x 3.38mm and with a height profile (including ball grid array) of just 0.35mm it is tiny, tiny enough to fulfill the requirements of t...
Bluetooth LE is not a fast wireless protocol, transfer speeds are usually measured in single-digit to low tens of kilobytes per second. This is generally not an issue unless large amounts of data need to be sent over the link, which is usually not th...
PCB Design
Abstract:
The SkyenLab Bluetooth module was developed using the nrf51422 QFN48 QFAC reference design as well as help from the Nordic Semiconductor support portal and white papers. A proof of concept circuit was developed to demonstrate f...
Our Project
This post is to clarify team SkyenLab’s scope for satisfying the senior design class requirements and Nordic Semiconductor requirements during the first semester (Aug. 2015 - Dec. 2015) of the teams senior design class. See SkyenLab’s pr...
