Introducing the NB-IoT service

It has been awfully silent on our blog lately but let me explain: We’ve been quite busy (among other things) building a new backend for Telenor’s NB-IoT network here in Norway. Getting data on to the Internet with NB-IoT is very simple; modules like the uBlox SARA N2 supports UDP and CoAP out of the box: Send a few AT commands via the UART to open a socket and off you go. »

The First Industrial Evolution

“We’ve got to pause and ask ourselves: How much clean air do we need?” Lee Iacocca Clean air Feeling drowsy ? Got a headache ? Hard to concentrate ? No worries. Check the CO2 levels in the office. If they are on the high side, go open a window and breathe some fresh air - or yell at the janitor in order to get him/her to fix the air conditioning. »

The Location Engine

Beyond Cool Every once in a while, a piece of tech comes along, that is so cool that it blows your socks off. Enter the DecaWave DWM1001 module. This little 19 by 26 mm beauty contains a nRF52 microcontroller and a DWM1000 ultra-wideband transciever. Stick 3 or more of them on the walls around the workplace and you have an indoor version of GPS. Instead of GPS satelites, you will have “anchors”. »

Arduino library for NB-IoT breakout

One of our latest projects is a breakout board for the uBlox SARA N2 module. The breakout itself isn’t very exciting – you’ve got a voltage regulator, uFl connector for the antenna, a sim chip, a reset button and the module itself. If you are anything like us you probaly want to pull out your little teal friend, aka “the Arduino” and test it out quickly before deciding to do anything further, preferrably without having to fiddle too much with AT command parsing. »

I'm a developer, and I don't like people

Ok. That was a bit harsh, but bear with me, I have a point. Sort of. How I decide if I want to use… things As a developer I’m often scurrying the wild internet for libraries and services to make my day easier. Often, there’s several competitors who wants to solve my problem and choosing which one who gets my attention is a journey. I thought I could explain what makes or breaks a first impression for a service in my book. »
