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).
A production screening is a rapid screening process sorting out those units which are not functioning because of manufacturing issues, such as cold soldering, usage of incorrect materials, usage of bad materials, etc.
A production screening is NOT a functional test which correctness of the application functionality is verified. Functional tests must...
I am developing an open source sensor beacon board named: YS-Beacon

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 and what are some of the motivations behind my work on a BLE-enabled model rocket during my fun and rewarding internship at Nordic Semiconductor.
Model rocketry is a popular and exhilarating hobby that has inspired many young (or the young-at-heart) makers, hackers, engineers and scientists through the fun, educational, and most importantly safe process of...
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 4.3 to the latest one. One may find it's tricky to keep track of all the issues from earlier Android versions and the changes in BLE APIs of different API levels.
To help you with this, our app developers have provided a note, discussing about most important changes and added features on newer Android version 5...
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 tool will be updated to support the Bluetooth Mesh when it is available.
Any one of the below x 2 or more, all of the same type is best during the evaluation
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 up quite a lot of space on your desktop. This often means that it is stowed away at a lab, or actually too expensive to buy. Since we have created the nRF52 Online Power Profiler, this can solve some issues, but what if the application has forgotten to turn off unnecessary power consumers, has wrong intervals between events or...
This is a summary of a three part blogpost series at www.norwegiancreations.com
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 coffee. This is mostly a great thing, but not when the office is mostly empty due to summer vacation. Getting a cup of coffee turned into a game of chance, where you could end up with a sip of four hour old coffee. Things had to change.
We decided to augment our coffee maker with an indicator showing...
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 protocol (that package, called RADIO, is loaded as a module by default) as that was the path of least effort.
For this project used:
The result of the project can be seen here (video)
If you are interested in trying the code yourself it can be found on...
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 nRF51422 as its main system-on-chip and has various sensors such as a camera, proximity/ambient light sensors, IMUs, and IR. It has two small motors in the back which act like two wheels and allows the robot to move with a differential drive configuration.
We had specific design objectives for mROBerTO in order to meet our needs: maximum (i) modularity for easy changes and upgrades...

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 compiled code to the nrf52 dev kit, and I will opdate this turotial when I have figured out how to do this (help is appriciated). I have now managed to flash the device.
I followed the blog post up to the point where a project template should be choosen (this was not...
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
C = LOOKUP[ ( C >> 24 ) ^ b ] ^ ( C << 8 )
where C is in a 32 bit register and
>> is a logical shift. The assembler is here, for the nRF52, as it uses the extended 4-byte Thumb2 instructions
// on entry // // r0 - current CRC // r1 - pointer to byte data to add // r2 - count of bytes to...
nRF5 SDK v12.0 is now available for Nordic developers to download and use in their designs. We’ve added quite a few things this time around to help you, the big story however is the production grade introduction of secure OTA-DFU with signing.
Living in a constantly updated world
Software updates are a part of everyday life today. Barely a month passes without at least a few things we own getting a software shot in the arm from their manufacturers, be it feature improvements or resolution of issues both major and minor. I hear from those I talk to...
There is seemingly a gap to fill in the world of Internet of Things (IoT) when it comes to proving a suitable operation system. Real-time operating systems (RTOS) that are specialized for network connectivity has existed for a while, but they all provide quite different benefits and drawbacks, and as such there is no on OS that rules the MCU market. In all this new OSes continue to appear.
What these OSes have in common is that they target resource constrained devices, focusing on low memory usage and low power to allow long battery life. The OSes are designed for...
Smart Remote 3 for nRF52 setting a new standard for voice input features and ultra-low power performance in smart remote controls
Nordic Semiconductor has recently released the latest member of their reference design for next generation smart remote controls – nRFready Smart Remote 3 for nRF52 series. This latest reference design takes the Nordic Smart Remote 3 performance to an entirely new level, most especially in 4 categories:
• Unparalleled audio input performance for voice (search/control)
• Outstanding ultra-low power performance
• Available on-chip resources and capacity for introduction of even more features than those already present
Nordic Semiconductor already provides reference designs for Altium Designer (R), but if you prefer EAGLE here is a quick guide on how to use the EAGLE reference design.
In a previous blog post, RK has shown us how to use Segger SystemView to monitor a bare-metal application as well as the Softdevice. Based on his work, we will see how to go further and add FreeRTOS to SystemView in order to monitor the RTOS tasks and events.
The following steps are based on the Heart Rate application with FreeRTOS example located in the SDK...
It is exciting to see that in the release of Android Nougat, in addition to 72 new emojis, support for Bluetooth pairing with NFC using the out-of-band (OOB) method is included. By utilizing NFC pairing on Android Nougat, you can avoid the need to type in a passkey on your product, and still perform a secure pairing. And it is so simple that your grandma can do it :).
The nRF52832 have a built-in NFC radio (dynamic NFC Tag). So the additional cost to enable NFC pairing to your product is very low. In fact, all you need is 2 small...
Wanted to tell you about this free J-Link upgrade for the BBC micro:bit.
With the firmware upgrade your micro:bit DAPLink will be transformed into a J-Link OB (on board), while still maintaining the Drag and Drop capabilities that developers currently use with the online tools.
So what do you need to do the upgrade? A micro:bit board, USB cable, the latest J-Link software installed, the upgrade HEX file containing the upgrade firmware.
It's really easy to do the upgrade, just have to put the micro:bit into Maintenance mode (see the video on the SEGGER...
