Segger RTT (Real-Time Terminal) supports multiple data channels. RTT Viewer uses channel 0 only, and implements multiple virtual terminals on top of this. The terminal can be switched by SEGGER_RTT_SetTerminal(). Channel 0 is used by NRF_LOG. NRF_LO...

Smartphones and tablets have revolutionized the manner in which people communicate with each other. Mobile applications with location-based features like Bluetooth beacons, WiFi, and GPS are helping people stay connected from any location. An increa...

Introduction The recently released nRF5 SDK for Bluetooth Mesh does not provide Keil project files for its example projects. Fortunately, it's relatively easy to set up your own project from scratch. This guide will show you how. While the list of ...

Here are two simple functions to use when you want to use timestamps for time measurement. uint32_t millis(void) { return(app_timer_cnt_get() / 32.768); } and for comperison of current with given timestamp with rollover correction (thanks to...

There are times that we needed to flash the nRF5x series on a PC where the development software were not installed. The problem could be worst when network access is limited. With a HEX file on hand, it is now possible to flash the nRF5x device usi...

Debugging interrupts in not an easy task. During the development of Jumper's Emulator, we gather few useful tips that we think can help you all when debugging the nRF52 interrupts. Hope it will help you all. https://medium.com/jumperiot/how-to-debug...

In my 2nd blog post in the series on Bluetooth 5, I go over one of the main features of Bluetooth 5: 2x speed. The advertised 2x speed of Bluetooth 5 is great! BUT, what does that even mean? Is it 2x "1 Mbps" = 2 Mbps? Is that even ach...

Embedded devices are no longer ship and forget products. Once deployed, a connected embedded device is updated and provide with services and not just functionality. This paradigm shift requires adopting DevOps practices and requires monitoring device...

Do you get sick of scouring the internet for Bluetooth 5 and BLE resources? Do you feel lost or get stuck during the development of your BLE project? Are you excited about Bluetooth 5 and its possibilities but don't know where to start? Do you experi...

About IoT security Since the Internet of Things is still in the emerging phase, ensuring security and privacy is an important issue that must be addressed and resolved now. The number of IoT and connected objects grows exponentially, so their secu...

We were trying to run the PPI example from the nRF5 SDK on our emulator. We quickly revealed a bug in the configuration of one of the timers by having a look at the HW log: Check out our Medium blog for the full story. Note: I could not find an...

If you haven't yet get to know command line interface (nrf_cli) module significantly improved in nRF5 SDK 14.0.0 please check this blog post: New command line interface - part 1 Enhanced logger and console It seems like a natural fit to use the con...

##Introducing concurrent MultiLinks I’d like to inform that it is possible to configure concurrent-multiple connections with several Centrals and Peripherals. This behavior can be possible to use examples in the nRF5 SDK v13. In the nRF5 SDK v13, ...

Thingy:52 Python Raspberry Pi Interface This blog is a follow up to both the Nordic Thingy:52 node.js/Raspberry Pi demos and the https://devzone.nordicsemi.com/blogs/1160/walkthrough-of-nordic-thingy52-nodejs-raspberry-pi/ blog posts. It will go thr...

In this article, I use the I2S peripheral of the Nordic nRF52832 to generate the waveforms required to drive the popular WS2812B RGB LEDs. http://electronut.in/nrf52-i2s-ws2812/

Thingy:52 Node.js Raspberry Pi Interface This blog post is a follow up to the Nordic Thingy:52 node.js/Raspberry Pi demos blog post, and will described how you can run and what to expect from each of the Node.js examples that have been provided in t...

This post describes how you can get the ble_app_hrs_freertos example project running in Atollic TrueSTUDIO 8.0 on a pca10040 board. This is a managed make build, it does not rely on the makefile provided by Nordic. No Nordic source files are change...

Just a quick post to say that we have ported the Adafruit GFX and SSD1306 libraries to nRF52832. Currently only I2C is supported. The code can be found here: https://github.com/electronut/ElectronutLabs-bluey/tree/master/code/bluey-OLED Here it's ...

At Jumper we’re developing tools that increase the happiness levels of embedded software developers. Our main tool to date is the Jumper Emulator. As a part of the development process we’re required to use embedded debuggers to verify that our emulat...

Bluetooth SIG has recently published a new standard, the Bluetooth mesh. The mesh capability is a significant update and enables radical new applications. This in turn means that there are significant changes, and many new concepts to learn for devel...

Introduction With nRF5 SDK v14.0.0, we have significantly refactored the Command Line Interface (CLI) module to make it more useful and user friendly. The new CLI has the following features: Support for multiple instances. Advanced cooperation ...

Introduction I would like to introduce simple source code that supporting NUS profile and pairing. Most of you will choose the proprietary profile to make your own application which is not provided by Bluetooth SIG. Since this reason Nordic is provi...

As you probably know having a build environment, you can replicate and deploy with ease has the potential to save a lot of R&D time. If you can also control its versioning so you would be able to "get back in time" for a build server th...

When we built our Bluey nRF52 BLE dev board, we were looking for an inexpensive option for our users to upload code to bluey and debug it using ARM GDB. We then came across the blackmagic probe (BMP) project - an Open Source debugging tool for embe...

The day after the Bluetooth SIG announced the 1.0 spec of the Bluetooth mesh we are happy to announce the nRF5 SDK for Mesh for our nRF51 and nRF52 Series SoCs. This first (v0.9.1) release is packed with new features and concepts for Bluetooth. What...
