The Field Application Engineers (FAEs) at Nordic Semiconductor work hard every day to help customers be successful with their designs. In that process, a number of issues come up repeatedly. This list was created to help the designer avoid those pote...

Hello World !! This is simple code which is compatible for nRF Blinky App which is based on Zephyr OS Bluetooth APIs. I've tested it on #nRF52840-PDK board. Isn't it simple ? You have to just replace $zephyr_base/samples/bluetooth/peripheral/src/ma...

Interfacing the Nordic Thingy:52 from the Amazon Alexa Voice Service just had to be done! In this blog post I will briefly explain how this demo was set up, but I will direct you to the GitHub page if you need more detailed information than what i pr...

After the release of nRF52840 Engineering B we have received several inquiries about the difference between Engineering A (nRF52840-QIAAAA) and Engineering B (nRF52840-QIAABB) reference designs. One reason for the inquiries is that after swapping Eng...

In mid-2017, I came across this project by James Munns. It essentially wraps the C SDK for nRF52 development boards, and provides bindings that can be called from Rust. James gave a talk to the Rust DC Meetup, remotely over video conference. This tal...

I've been looking for an excuse to write a low-latency, Enhanced ShockBurst (ESB), radio protocol that I can reuse when building remote control toys. Although Bluetooth is great for a lot of use cases, working with the Nordic radio's proprietary mode...

Posting this here in an effort to save the time of anyone else who is wanting to control a device from a desktop computer. Our application is a motor control device that is wirelessly controlled from a desktop computer. This is not really what BLE w...

Second part of the series Writing Bluetooth LE firmware the easy way blog. This second part shows how to read and advertise the environment sensor data (BME280 using Motsai Neblina module and BME680 using breakout board). Still with only a few line...

The first generation of wireless PC accessories to achieve widespread success (the ones that shipped with a dongle in the box) adopted 2.4GHz radios because these radios offered the optimal trade-off between power consumption, throughput, and range. ...

Writing a BLE firmware can now be done with a few lines of code. The code example bellow is all you need to write for a non-connectable BLE firmware that advertise a counter value every second in the manufacturer private data. More details with ful...

Hello I wrote a tutorial on using the nrF52 Development Kit with Keil MDK. www.keil.com/appnotes/docs/apnt_308.asp This document features essential debugging capabilities of the nrF52 series. ETM Instruction Trace: provides program flow debuggin...

1.Profile During connection procedure of BLE, there are three packages: SCAN_REQ, SCAN_RSP 和 CONNECT_REQ。 SCAN_REQ： Scan request, issued by MASTER DEVICE, send to SLAVE DEVICE，sent by the Link Layer in the Scanning State, received by a Link Layer i...

1.Profile MTU: ATT Maximum Transmission Unit (MTU) is the maximum length of an ATT packet. The ATT MTU is defined by the L2CAP and can be anywhere between 23 and infinity. The implementation of the Bluetooth stack is the key factor of determining th...

Today I tried to find the better ways to debug program on nRF52840 PDK from CLI on linux. The ways that I tried [Failed] openocd (both stlink and jlink) & gdb [Succeeded] JLink & JLinkGDBServer & gdb OpenOCD (failed) I could conn...

Hello, We are currently looking for an Embedded / nRF Developer in Stuttgart that will help us to further develop FruityMesh (https://github.com/mwaylabs/fruitymesh) and our commercial Product BlueRange (https://bluerange.io/). C++ knowledge is man...

The purpose of this tutorial is to expound my notes on the studies I have done on the use of nRF51, but also serve for the nRF52, and thus share with the beginner as I of the Portuguese language. This tutorial is continuity in the [previous tutorial]...

This tutorial aims to help Portuguese language beginners, like me, with the nRF5x family and who chose to use Eclipse as a development tool. The tutorial will be very simple and we will use the Eclipse Oxygen and the GNU MCU Plugin, in addition to G...

Hi, Using Git and choosing the right workflow is essential when you want to implement DevOps practices as part of your SW development. When it comes to embedded SW things start to get a bit rough. Take a look at the blog post below to learn how to u...
