#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...
TL;DR: It ignores whatever the computer tells it to do and does an automatic detection.
And the reason? UART terminals are not doing flow control settings in a consistent way, and in some cases incorrectly. Therefore the JLink OB firmware will detec...
Introduction
A few months ago I started running again. Music helps me to stay motivated. Since most earphones keep falling out, especially when the sweat comes out, I googled for some sports earphones. After reading some good reviews I bought the Pl...
List of changes from µESB to nrf_esb
All functions, structs, enums and defines have been renamed from uesb_xxx to nrf_esb_xxx.
Events:
Events used to be triggered within radio interrupt context in µESB. This guaranteed that no additional radio...
Some news I wanted to highlight from the SDK team.
What
With the release of nRF51 SDK v7.0.1 in Oct 2014, we introduced support for CMSIS pack. The main motivation was to have an easy to use dependency manager, which defines an open standard define...
With the alpha release of nRF5 SDK v11.0 in December 2015, we took a major step to enable the smooth migration path within the nRF5x family for developers.
A clear indicator of this, is visible by the name nRF5 SDK, compared to the previous nRF51 an...
The information in this post is outdated. Please refer this tutorial for updated information.
Motivation
Monitor Mode Debugging solves the biggest problem when debugging nRF5 devices. It allows BLE applications to be debugged without crashing af...
Hi developers,
We just released a BLE-Scanner App on the iTunes , and free for download.
Alos, the app is an open source project for iOS (Swift and Objective-C):

##Measuring humidity using TWI on nrf52##
In this post I will explain how the nRF5x chip can be used to communicate with a sensor over TWI (I2C). To run this example extract the files to examples -> peripheral in the SDK for nrf52 and open the ...
Since Nordic Semiconductor released the S130 SoftDevice for our nRF51 ICs in early 2015, we have been working hard to make our Bluetooth low energy protocol stacks more feature rich and more configurable than ever before. The S130 now does everythin...
