It’s the same story every year. At the horizon is a loved one’s birthday, or an anniversary, and I want to make them something special. Buying something won’t do. Oh no, I have to design and build it myself. I would then start with a simple idea, and then complicate […]

Developing a BLE application requires a lot of domain specific knowledge. You need to learn a lot of languages that target specific platforms. Eg. Java or Kotlin for Android Native Application development, or Objective C or Swift for IOS development. Moreover, you need to be proficient in the tools, like […]
Introduction I worked for almost two decades in the software industry. In the early 2000s, I was developing applications on Windows, Linux, and various flavours of Unix. On the Windows side, we had Microsoft Visual Studio, MFC, NMake, and CL. On the Linux/Unix side, we had GCC, POSIX and various […]
If you are planning to buy a Bluetooth Low Energy (BLE) board or want to incorporate BLE functionality in your product, then hackaBLE could be a great candidate for the job! hackaBLE is a tiny Open Source Nordic nRF52832 based BLE development board developed by Electronut Labs that you can […]
Last weekend, my colleagues and I decided to go on a trek to Kudremukh peak in the Western Ghats. We thought, how about recording the GPS data throughout the trek. We quickly assembled a GPS module with our upcoming board blip, which is a development board based on Nordic’s nRF52840 […]
This post will have enough information to help someone understand the startup code and all the intermediate files present in a C project for a microcontroller. This will be explained through a minimal blinky example that pulls no external dependencies. Over here at Electronut Labs, we have been using the […]
Introduction I recently wrote about using Thread and MQTT-SN on the Nordic nRF52840 multiprotocol SoC. One thing I did not cover in detail is Thread Commisioning – a secure process by which a device joins a Thread network. I side-stepped the process by passing the network credentials directly to the […]
Introduction IoT is in the air. Impossible to surf the web in peace without tripping over some gushy article on billions of devices connecting to the Internet. The Teapot yelling at the Washing Machine has already become a stale joke. There are myriad complex technologies coming together to make this […]
Here at Electronut Labs, we work extensively on Bluetooth Low Energy technology, and we have chosen Nordic Semiconductors nRF5x series boards for developing our products. (We have our own range of breakout boards based on nRF5x series microcontrolers. You can visit out website or tindie to purchase our boards.) We […]
Introduction Do you sometimes wonder how polluted the air inside your house is? Our surroundings are constantly degrading, and there are innumerable disease that can be caused by living in unhealthy, impure and polluted surroundings. I know there are a number of devices in the market that will measure the […]
Introduction Last year, I had written about my experience of getting started with STM32 microcontrollers. There was (and still is) a bewildering number of choices when it comes to ARM programming. After some research, I had settled on using ARM GCC, Eclipse, and Standard Peripheral Library to program an STM32F103RB […]
It’s hard not to like a project with blinking LEDs. Red, Green, Blue, Yellow,… and then there are RGB LEDs where you have three lines to control the colour. In 2010 WorldSemi launched the WS2812 – an RGB LED and driver chip integrated into one package, which could be daisy-chained […]
