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....

Introduction There is a use case that I've seen several times recently that I find interesting due to the fact that its security requirements aren't directly addressed by the Bluetooth Low Energy (BLE) standard. It goes something like this: ...

The Zephyr Project RTOS The Zephyr Project RTOS is a recent effort by the Linux Foundation to provide the embedded world with a free, secure and fully-featured Real Time Operating System. It is designed from the ground up to be a modern, scalable, s...

It´s exciting to see that our friends at Sony Mobile Research and Incubation have released a desktop application called Otii, which supports our Power Profiler Kit. The beta version of the Otii application is cross platform and runs on Windows, Linu...

The challenge As a product is getting into the production phase, the need of a fast and standalone screening facility on the production line arises. Here I'm introducing a production screening setup based on Bluetooth Direct Test Mode (DTM). What ...

I am developing an open source sensor beacon board named: YS-Beacon which contains: nRF52832 DAPLink - LPC11U35 9-Axis Motion Sensor Ambient Light Sensor、Proximity Sensor and 3D-Gesture Sensor with Built-in IR LED Digital Pressure Sensor Ste...

Official Launch Video Welcome to this 2 or 3-part blog about the nRF52 Rocket, a BLE-enabled model rocket, which you’ve just seen soaring through the air in the video above. In the first part of blog, I will briefly introduce what model rocketry is ...

BLE is native supported on Android from v4.3. It has been continuously improved as Android evolving. It's getting more and more complex with additional features. It's important that a Bluetooth app should work smoothly on all Android versions, from 4...
