The MQ Telemetry Transport (MQTT) protocol is hugely popular in IoT because it is lightweight and versatile. In this post we will enable Transport Layer Security (TLS) in the mqtt_simple sample from the nRF Connect SDK (NCS) and then connect it to a ...

We released a small update late last week. It’s a follow-up to our last release of 2019, and like its predecessor, this release, 2.1.2, aims to improve the general stability of nRF Connect for iOS as well as take care of some of those loopholes...

I have spent a bit of time recently experimenting with different TLS credential configurations using nRF91-DKs. Eventually I got to the point where I wanted to do things like swap out the certificates on a DK for different types or connect several DK...

This blog post contains answers to questions asked during the "Embedded Antennas for IoT" webinar hosted by Nordic Semiconductor 17.10.2019. You can watch a recording of the webinar here. You can download the slides at the bottom ...

It has taken a lot longer than we previously thought, but we made it here, to our first big point release for nRF Connect 2.0. Throughout this “two-point-oh" journey, you’ve been an invaluable asset to us, both for your patience, your sup...

This page describes an easy workaround for the flashing error you get in Keil uVision when you are using nRF5 SDK v16 on nRF52833 chips.  The assumption is that you have installed the latest versions of nRF MDK and nRF-Command-Line-Too...

The nRF9160 SiP supports the use of both LTE-M and GPS. We want to show how these can be used in an application at the same time. In this project we demonstrate this by using the nRF9160 DK to send the GPS position of the DK to Google Cloud, which w...

It's been a month since we last spoke, when we announced the release of nRF Connect for iOS 2.0. What a day that was, wasn’t it? In any case, we’re here because, since then, we’ve made three successive bug-fix releases. With&nb...

I have been asked several times about variations of the following advertising scenario, so I decided to make a blog post that I can refer to, and hope it might prove useful for others out there that are looking to do similar things. I recommend ...

In this post I will give you an introduction to the four kinds of data you need to consider when developing an IoT product: Device State Device Configuration Past Data Firmware Updates It's these messages that are exchanged between y...

There are smart home applications that require an extended radio range. Is it possible to use Zigbee/BLE multiprotocol solution to increase the Zigbee mesh network coverage?

This blog post contains answers to questions asked during the "Introduction to Nordic Thingy:91" webinar hosted by Nordic Semiconductor 22.08.2019. You can watch a recording of the webinar here. You can download the slides at the bottom of this ...

Thingy:91 FAQ Should I update to the latest firmware? Yes, its recommended to update the firmware to get the latest and greatest functionality. See Update Thingy:91 firmware. What if I want to try it on NB-IoT? Due to restrictions in use of TC...

For the past ten months, we’ve been busy, hunkering down in front of our keyboards, keeping the blinds down, shooting mean looks at our bosses whenever they dared interrupt us. And of course, all the while, we were blasting some Linkin&nbs...

Continuous delivery is in important aspect of short time to market and since the nRF9160 supports firmware over the air updates we want to ship a new firmware to our development boards every time we update the application.

Nordic's Power Profiler Kit (PPK) is an inexpensive piece of hardware that can provide a significant amount of insight into the operation and performance of your project. Although there is a lot that you can learn by experimenting with the PPK using ...

Disclaimer: This is a student project, and thus we can not guarantee that everything will work perfectly. This blog post covers how to connect to Google Cloud with an nRF9160 DK. The nRF9160 DK is using MQTT protocol to communicate wit...

The production firmware version v1.0.0 is released for the nRF9160. - Release notes for the nRF Connect SDK v1.0.0 (NCS) - Release notes for the Modem Firmware v1.0.0 (MFW) Update NCS to v1.0.0: cd ncs/nrf git checkout master git pull ...

I implemented parts of the BLE-MIDI service along with a small example application. I wanted to share it here on the blog, in case someone would find it useful. The intended audience is primarily someone looking to send MIDI data over Bluetooth ...

Google I/O was wrapped up last week. One session was particularly interesting: "Connect Thread Devices to the Cloud with IoT Core". In it Google explains how the Thread protocol and their Cloud IoT Core are the future of IoT connectivity. T...

This blog post complements the video with the same title, see this. Introduction There are many sources of information on the web trying to characterize the new low power cellular technologies LTE-M (Cat-M1) and NB-IoT (Cat-NB1). Unfortunately, ...

Trace Collector app collects UART traces from the nRF91, over serial port. User can collect traces with this tool and send the trace files(binary) to Nordic for parsing and processing. In addition to the log file of the Link Monitor( you can get it c...

Recently, we've updated the SEGGER Embedded Studio Nordic edition (SES) to version 4.16 (SES Nordic Edition is special version of SES built specifically for nRF Connect SDK).  This updated version introduced some new features to support bui...

In this example we are using the nRF Connect for Cloud Device API, which is a free service for protyping IoT products and is built on top of AWS IoT, to store dust sensor readings. The API is device-agnostic and can store data from any kind of device. In this example we use an Espruino Wifi (firmware version 2v01). The Espruino will connect to the AWS IoT MQTT broker using TLS, and regularly publish temperatore and…
