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...

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...

nRF-connect-Mesh PC tool allows the user to demonstrate the nRF OpenMesh and the Mesh Device Firmware Update (DFU). The Mesh DFU will be used for nRF OpenMesh and the Bluetooth Mesh when it is made available. The nRF OpenMesh used is v0.8.7. The to...

Many developers might be familiar with the problems that may arise when wanting to measure current consumption, especially with applications using from a couple of µA to some mA. You most probably have to have some very expensive equipment that takes...

This is a summary of a three part blogpost series at www.norwegiancreations.com Introduction We at Norwegian Creations work out of the coworking space DIGS in Trondheim. In our office, we have a coffee maker capable of making large amounts of cof...

The ultra simple to use pxt editor for Microbit (https://pxt.microbit.org/) supports sending data using the nRF51822 radio. The tool supports using both BLE and proprietary protocols. For this project that I did with my kids I used the proprietary...

mROBerTO (milli-ROBot-TOronto) is a small modular millirobot designed and implemented for swarm robotics research. It was first featured in the 2016 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS). It consists of an nRF5142...

Hi. I'll introduce "neoFlash" produced by Mobilian. neoFlash is whole new BLE development toolkit & production solution. With this solution you can design, implement your idea and produce your target product. neoFlash is composed of ...

Hi I followed this Blog post on how to use Segger embedded studio(SES) to compile nrf5 examples and got into some truble with the newest version of SES v3.10c. And this blog post will tell how I solved the problem. I have not tried flashing the comp...

Working on fast calculation of CRCs I have an algorithm which uses a precalculated fixed lookup table to process data 1 byte at a time generating a 32-bit CRC. The calculation it's actually doing if the current CRC is C and the next byte is b is C =...
