Let's start a conversation

A feature we had to sacrifice on the “getting done in time” altar was the downstream messaging (ie sending messages to the devices, not just receiving). We had a clear idea on how we should do it, but our main focus was to get the essentials up and running so we had to postpone it a bit. As with any LPWAN technology the first thing you’ll try is to get bytes through the system, then something slightly more useful like monitoring data but after a while you realise that you’ll need downstream messaging to really make it a useful technology. »

All Quiet on the Exploratory Front?

Nope. We’ve been busy. Real busy. All of us. Making stuff. We even had deadlines. You may already have been playing around with LoRa and our EE02 module. This required that you set up a dedicated network and had access to a gateway. For some time, this was the only viable option if you needed low power IoT connectivity. But now - something has changed. On october 1st, NB-IoT functionality was enabled in all of Telenor’s base stations in Norway. »

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”. »
