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. »

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. »

How to open an IoT lab... with IoT!

Not very long ago someone asked us to come up with something for the ribbon cutting ceremony for the opening of the IoT Protolab here in Trondheim with “IoT” being the operative word. They already had some suggestions that included a samurai sword and a robot but that doesn’t mix well with a room full of people. Strange that. The IoT Protolab is a joint venture between Wireless Trondheim, Telenor and NTNU. »
